CERCETĂRI PRIVIND PRODUCTIVITATEA AGROECOSISTEMULUI GRÂULUI DE TOAMNĂ ÎN CONDIŢIILE DE PRODUCERE ALE REPUBLICII MOLDOVA
Authors: RACOVIȚĂ Gheorghe
Published: April 2024

The research focused on examining the elements of agroecosystems, with a particular emphasis on the interconnections between „soil-plant”, energy flow dynamics, and human interventions aimed at achieving the primary agricultural objective: the harvest. The assessment of both qualitative and quantitative parameters of winter wheat yiled provides insights into the potential and realized productivity of the crop under specific production conditions, including factors related to potential and effective soil fertility. Discrepancies between reported harvest values by agricultural enterprises and those observed in field research were significant. Based on soil bonitation data, potential harvest values were calculated for winter wheat agroecosystems within the administrative territories of Chistelnita and Tirsitei villages, Telenesti district. Assessment of organic matter mineralization processes in winter wheat agrocenoses revealed negative values in the energy balance, indicating potential soil degradation. Analysis of input/output ratios offer opportunities to correct and complete formulas governing the energy flows cycle within agroecosystems, aiming to mitigate soil degradation and preserve fertility levels for sustained agricultural productivity and food security.
Au fost cercetate componentele agroecosistemului grâului de toamnă, accentul fiind plasat pe analiza relaţiilor de interacţiune sol-plantă, a legităţilor fluxului energetic şi a funcţiei reglatoare exercitate de om în scopul obţinerii produsului agricol principal – recolta. Cercetarea indicilor calitativi şi cantitativi ai recoltei grâului de toamnă oferă informaţii privind productivitatea potenţială şi reală a culturii în condiţii concrete de producere. Cercetările au arătat o diferenţă semnificativă dintre valorile recoltelor declarate de reprezentanţii întreprinderilor agricole şi recoltele obţinute în câmp. În baza notei de bonitare a solului (cernoziom argilo-iluvial, cernoziom obişnuit şi cernoziom stagnic) a fost calculată recolta potenţială ce poate fi obţinută în cadrul agrocenozei evidenţiate cu cultura grâu de toamnă în comunele Chiştelniţa şi Tîrşiţei, raionul Teleneşti. Evidenţierea consumului elementelor biofile în cazul recoltei declarate şi a recoltei în câmp oferă date privind manifestarea proceselor de degradare agrochimică a solului exercitat de cultura grâului de toamnă în condiţii actuale de producere. Utilizarea datelor privind exportul elementelor biofile prin recoltă oferă posibilitatea de corecţie şi completare a formulelor definitivate privind circuitul substanţelor nutritive în agroecosistem, pentru atenuarea degradării agrochimice a solurilor, menţinerea fertilităţii efective la nivelul fertilităţii potenţiale şi consolidarea capacităţilor de asigurare a securităţii alimentare.

Ecological farming can be successfully initiated and implemeted when there is a consistent flow of high-quality organic matter in the soil and the soil is rich in biologically available phosphorus. Pedological research in the Lower Dniester meadow area revealed the presence of 600 hectares of deep humic post-marsh clayey alluvial soils exceptionally rich in available phosphorus, ranging from 5-10 mg/100g. These soils present ideal conditions for ecological agriculture, yielding highly favorable results. Large-scale field experiments in ecological agriculture were conducted on a 10-hectare plot under irrigation, where early potatoes were planted at the end of May following the incorporation of a green mass crop consisting of a vetch + wheat mixture. The results were promising, with potato yields reaching 31 tons per hectare.
Agricultura ecologică poate fi inițiată și aplicată cu succes dacă există un flux permanent de substanță organică calitativă în sol și solul este bogat în fosfor biologic mobil. Cercetările pedologice au constatat că în lunca Nistrului Inferior există 600 ha de aluvisoluri argiloase postmlăștinoase profund humice foarte bogate în fosfor mobil (5-10 mg/100g), sol care poate fi utilizat în agricultura ecologică cu obținerea unor rezultate foarte favorabile. Testarea la scară mare, în teren, a posibilității utilizării în agricultura ecologică, în regim de irigare, a unui teren (10 ha) semănat la sfârșitul lunii mai cu cartofi timpurii după încorporarea în sol a recoltei de masă verde a amestecului de măzăriche+grâu s-a dovedit a fi efectivă.

The Earth upward trend in average annual air temperatures has led to increased physical evaporation of water from soil and plant transpiration. This phenomenon raises questions about the adequacy of soil moisture reserves to support optimal plant growth under changing environmental conditions. In addition to precipitation, factors such as constanty updated sunflower varieties (hybrids), mineral nutrition, and irrigation techniques significantly impact sunflower yields. This study aims to assess the correlation between key climatic parameters in the Republic of Moldova and sunflower yield. Analyzing data on average annual air temperatures and spring moisture reserves from 2006 to 2020, it was found out that, on average, climatic conditions in this region ensure a sunflower yield of up to 20 quintals per hectare over a 15-year period. Knowing the spring reserves of productive moisture in the soil and precipitation levels from April to July allows for predictive modeling of sunflower yield.
Тренд изменения среднегодовых температур воздуха является положительным, а их повышение увеличивает физическое испарение воды с почвы и транспирацию растений. В связи с этим актуально изучение вопроса, позволяют ли запасы продуктивной влажности почвы раскрыть потенциал растений в условиях критического земледелия. На урожайность подсолнечника, кроме осадков, влияют такие факторы как постоянно обновляемые сорта (гибриды), минеральное питание, орошение и другие элементы технологии. Цель наших исследований – изучение корреляции основных климатических условий Республики Молдова с урожайностью подсолнечника. Проанализированы данные среднегодовых температур воздуха и весенних запасов влаги за период 2006-2020 г.г. Установлено, что в среднем за анализируемые 15 лет климатические условия нашего региона могут обеспечить урожайность подсолнечника не выше 20 ц/га. Зная весенние запасы продуктивной влаги в почве и количество осадков за апрель-июль месяцы, можно прогнозировать урожайность подсолнечника.

For the intensive development of beekeeping, the creation of new preparations is of particular importance, as they stimulate the growth of bee colonies and contribute to increased productivity. The research aims to assess the impact of the CobalRibo biostimulator (aqueous solution of hexamine cobalt (III) chloride and Rebaudioside A glycoside) on the growth of bee colonies, early developmental stages, and overall productivity. It has been determined that the optimal dose of the CobalRibo biostimulator for early spring bee feeding, in the absence of a maintenance nectar-pollen crop, is 3 ml/L of sugar syrup. Early spring bee feeding with a mixture of 50% sugar syrup and 3.0 ml/L of CobalRibo biostimulator, in a quantity of 1.0 L per bee colony, administered once every 6 days starting from April until the beginning of white acacia flowering, enhances queen prolificacy, promotes the growth of the number of capped brood, and increases honey yield.
Pentru dezvoltarea intensivă a apiculturii, o deosebită importanță are elaborarea noilor preparate, care stimulează creșterea și contribuie la sporirea productivității albinelor.

Published: April 2024

Há diferentes formas de identificação dos sistemas frontais como, por exemplo, algoritmos que utilizam dados de reanálise para identificação objetiva desses sistemas. Porém, devido à complexidade dos sistemas frontais, a identificação objetiva pode levar a muitos erros nos resultados, sendo a análise sinótica tradicional (manual) de cartas meteorológicas o método ainda mais confiável para a identificação das frentes. Com isso, os objetivos do presente estudo são (a) identificar o número de passagens de frentes frias pelo sul do Rio Grande do Sul (SRS) e sul de Minas Gerais (SMG), entre 2009 e 2021, com base em cartas sinóticas, (b) determinar a porcentagem de sistemas que passam pelo SRS e chegam ao sul SMG, (c) calcular a contribuição das frentes frias para o total sazonal de precipitação e (d) realizar uma avaliação de como a temperatura da superfície do mar (TSM) interfere no deslocamento das frentes frias entre o SRS e SMG. As frentes frias foram identificadas nas cartas sinóticas disponibilizadas pelo Centro de Previsão de Tempo e Estudos Climáticos do Instituto Nacional de Pesquisas Espaciais (CPTEC/INPE). Por estação do ano, considerando o verão, outono, inverno e primavera, o número médio de frentes frias registradas no SRS é de 10, 12, 13 e 14 e no SMG é de 1, 4, 7 e 5 sistemas, respectivamente. Cerca de 30% das frentes frias que passam pelo SRS também chegam ao SMG e o tempo e a velocidade média anual de deslocamento das frentes é de dois dias e 6,8 m/s, respectivamente. As frentes frias têm maior contribuição no total sazonal de precipitação no inverno tanto no SRS quanto em SMG. Com relação à TSM, foi analisado o número de frentes frias que se deslocaram do SRS para o SMG em situação de TSM maior e menor do que um desvio-padrão e meio (1,5𝜎) em relação à climatologia. Em situação de anomalia negativa (positiva) de TSM, 70% (30%) das frentes frias conseguem chegar no SMG.

Published: April 2024

O conhecimento do comportamento dos elementos meteorológicos de uma região é de grande importância para a tomada de decisões, principalmente no cultivo agrícola, pois influenciarão diretamente no crescimento e desenvolvimento das lavouras. Portanto, o objetivo deste trabalho foi conhecer a distribuição dos elementos meteorológicos pela distribuição não paramétrica de Kernel e analisar sua influência no cultivo de culturas. O estudo foi realizado com dados obtidos da Estação Meteorológica Automática A854-Frederico Westphalen. A estação está localizada no município de Frederico Westphalen, Rio Grande do Sul, Brasil. Os elementos meteorológicos utilizados no estudo foram a radiação solar global incidente, precipitação e temperatura média do ar. Os dados foram organizados em geral, por ano e por mês. Foi utilizado o método não paramétrico de estimativa da densidade do kernel. A aplicação do método não paramétrico de estimativa de densidade Kernel aos elementos meteorológicos permitiu observar a distribuição ao longo dos 10 anos de registo globalmente, no ano e no mês. Além disso, a distribuição possibilitou identificar os picos mais altos que estão relacionados a densidades mais altas. A observação de 10 anos de registros de dados de radiação solar, precipitação e temperatura do ar da estação meteorológica pelo método não paramétrico de distribuição de Kernel dá uma indicação de como os elementos estão se apresentando no período. Apesar de restrições específicas, o clima/tempo é adequado para o cultivo de espécies que vêm sendo utilizadas na região, seguindo seu zoneamento.

Authors: Carpenedo Camila Bertoletti , Bonfim André Luiz de Souza , Limberger Leila
Published: April 2024

Estudos mostram uma tendência de aumento nos extremos chuvosos na Região Sul, a qual se destaca na ocorrência de desastres naturais hidrometeorológicos no Brasil. Assim, este estudo tem como objetivo investigar a variabilidade climática e os padrões de circulação atmosférica associados aos extremos chuvosos em Curitiba - PR no verão (1980-2021), visto que este é o município mais populoso da Região Sul. Foram utilizados dados observados/estimados e índices de diferentes fontes (SPEI Global Drought Monitor, ERA5, NOAA, CEDEC). Através da técnica de composições, os resultados mostram que nos extremos chuvosos em dezembro predomina resfriamento no Pacífico equatorial, favorecendo a fase positiva do Dipolo Subtropical do Atlântico Sul (SASDI) e negativa do Dipolo do Oceano Índico. Também há predomínio de fase negativa da Oscilação do Ártico (AO) e da Oscilação do Atlântico Norte. Em janeiro há um padrão de enfraquecimento da Zona de Convergência do Atlântico Sul (ZCAS) oceânica, associado ao padrão de intensificação do jato de baixos níveis da América do Sul (JBNAS), e predomínio de fase negativa da AO. Em fevereiro predomina ZCAS enfraquecidas, associadas ao padrão de intensificação do JBNAS e do ramo sudoeste da Alta Subtropical do Atlântico Sul, a qual bloqueia e estaciona os sistemas sinóticos na costa Sul, contribuindo para o aporte umidade. Há predomínio de La Niña-Pacífico Central, favorecendo a fase positiva do SASDI. O monitoramento dos índices climáticos e dos padrões de circulação atmosférica pode auxiliar na previsão de extremos chuvosos em Curitiba e na prevenção dos impactos associados aos desastres naturais hidrológicos.

Published: April 2024

A evapotranspiração de referência (ETo) é um parâmetro importante para o planejamento e gerenciamento dos recursos hídricos. O objetivo deste estudo foi comparar os métodos de estimativa da evapotranspiração de referência propostos por Hargreaves-Samani, Blaney-Criddle e Priestley-Taylor em relação ao método padrão de Penman-Monteith para o município de Codó, Maranhão, Brasil. Os dados meteorológicos utilizados para a estimativa da ETo foram obtidos na Estação Meteorológica Automática, instalada no Campo Experimental do Instituto Federal de Educação, Ciência e Tecnologia do Maranhão (IFMA), localizada no município de Codó, MA. O período de coleta de dados foi de 2009 a 2013. Foram quantificados valores diários de temperatura do ar máxima (Tmáx), média (Tméd) e mínima (Tmín), umidade relativa do ar máxima (URmáx), média (URméd) e mínima (URmín), direção do vento (Dv), radiação solar global (Rs), saldo de radiação (Rn), precipitação (P) e velocidade do vento (V/v). Para a análise do desempenho dos métodos foram considerados os coeficientes de correlação (R), de determinação (R²) e o índice de Willmott (c). Durante todo o ano, a estimativa da ETo pelo método HS superestimou a ETo obtidas por PM, BC e PT. O mesmo ocorreu com PT em relação a PM, mas com uma menor magnitude. Independente da estação do ano, o método de BC foi o que apresentou melhor desempenho de dados em relação ao método padrão PM-56 e o de HS não apresentou boa concordância para a ETo nas condições climáticas de Codó, MA, para as estações do verão e outono.

Authors: Couto Rodney Murillo Peixoto , Santos Priscilla Soares dos , Godoi Mauricio Neves , Miguel Maiara Cabrera
Published: April 2024

Here, we highlight significant expansions in the distribution of Rhinella ocellata in the state of Mato Grosso do Sul, Brazil. Originally described as Bufo ocellatus by Günther (1858) and subsequently reclassified as Rhinella ocellata by Cochran (1954), this species belongs to the Rhinella margaritifera group. Novel records were obtained through nocturnal surveys of anurans in two previously undocumented locations for the species. In December 2019, in Vista Alegre, Maracaju, the species was identified approximately 190 km south of the nearest record in Miranda. The second record, in Aparecida do Taboado, November 2021, expanded the distribution by 300 km east of Camapuã and 375 km south of Caldas Novas, Goiás. The observation of males vocalizing near ponds formed by recent rainfall suggests reproductive activity. These findings significantly underscore the expansion of Rhinella ocellata distribution and mark its first record in the state of Mato Grosso do Sul, providing valuable contributions to the understanding of the ecology and dynamics of this species occurrence.

Published: April 2024

Digital transformation is a key factor in realizing innovative development and driving economic growth, driving companies to improve competitiveness, efficiency, and sustained growth. Innovation investment is an important source of funding for corporate innovation. Does digital transformation affect the tilt of corporate economic resources toward innovation investment projects? To answer the above question, this paper empirically examines the impact and mechanism of digital transformation on corporate innovation investment using a panel regression model with A-share listed companies in Shanghai and Shenzhen, China, from 2012 to 2022 as the initial research object. The study shows that the digital transformation of enterprises will increase the level of innovation investment, and this effect is realized by increasing the level of human capital, reducing surplus management, and lowering the level of cash holdings. The results of this research will provide strong support for enterprises to improve the motivation of innovation investment and innovation quality, help realize the goal of high-quality development of China's economy, and provide an important theoretical basis for relevant policy formulation and decision-making.
Rethinking and Solving the Model for Protecting Enterprise Data
Authors: Cao Rui
Published: April 2024

With the rapid development of China's digital economy, data competition disputes among internet enterprises have become increasingly diverse and complex. The theory of commercial data empowerment has been proposed by academics as the value of commercial data becomes more prominent. However, this theory faces the problem of insufficient legitimacy at the theoretical level, including property right theory, copyright theory, and new property right theory. Considering the current lack of clarity regarding data ownership, Chinese judicial practice mostly relies on anti-unfair competition laws to regulate competitive behavior. Legitimacy is determined through the use of 'general terms' and 'trade secrets'. However, these methods have certain limitations. Considering recent developments in the commercial data industry and judicial practice in China, Article 18 of the Draft Revised Anti-Unfair Competition Law (Draft for Public Comments) (Special Article on Commercial Data) aims to provide better protection for enterprise data.

Authors: Liu Jiaxin
Published: April 2024

To explore the law of land use change in Suizhou City, strengthen land resource management and improve the efficiency of land resource utilization, this paper study the dynamic changes and trend prediction of land use in Suizhou City. In this study, three periods of Landsat-TM/ETM and Landsat 8 satellite image data in 1995, 2005 and 2015 were selected, and the evolution of land use pattern in Suizhou City from 1995 to 2015 was analyzed by calculating its land use area and percentage, land use dynamics and establishing a land use transfer matrix. The PLUS model Kappa coefficient was found to be 0.81 and the accuracy meets the requirement. We considered six natural factors, two social factors, and one limiting factor and predicted the land use pattern of Suizhou City in 2035. The results show that from 1995 to 2015, the proportion of cultivated land and forest land area was 33.43%~34.23% and 61.29%~62.49%, respectively. The proportion of unused land had always been the lowest, accounting for 0.01%. The proportion of grassland, water area, and construction land was 0.25%~0.27%, 2.48%~2.83%, and 0.60%~2.20%, respectively. The land area of construction land in Suizhou City changed the most dramatically among all land types from 1995 to 2015, with a land use dynamics of 13.28%. From 1995 to 2015, cultivated land in Suizhou City was mainly transformed into construction land and forest land, accounting for 42.28% and 44.28% of the outflow area, respectively. The conversion of forest land to arable land accounted for 66.50% of the transferred area. The increase in construction land mainly derived from arable land and forest land, accounting for 66.60% and 32.21% of their transferred area, respectively. The Kappa coefficient of the PLUS model was 0.81, indicating that the model can be used for the study of land use change in Suizhou City. The prediction results indicate that the construction land area in Suizhou City will significantly increase by 2035 and expand to the southwest, northeast, northwest, and central regions, with an increase in forest land area, a decrease in cultivated land area, and a slight reduction in grassland, water area and unused land area. The study results can provide a decision-making basis for land use policies and planning measures in Suizhou City, and also facilitate relevant departments to guide urban construction and land development activities more reasonably.

As comunidades ribeirinhas, são reconhecidas politicamente, entretanto, apesar dos amparos legais, ainda vivem expostas a diversos riscos, devido a fatores socioambientais, como a falta de acesso a sanemaneto básico, água potável e educação em saúde. O presente artigo aborda as consequências da exclusão social, a partir da realidade precária de saneamento básico e ambiental na comunidade ribeirinha, localizada no município de Tucuruí-PA, bairro Rio Onze – Porto Pesqueiro. Objetivou-se, portanto, realizar uma análise observacional para verificar os problemas mais nevrálgicos na localidade em questão, relacionadas às questões de saneamento básico e ambiental, carência de políticas públicas e as possíveis implicações no processo saúde-doença. O estudo é de caráter qualitativo descritivo, de abordagem observacional, visto que se registrou informações sobre o espaço geográfico, sem interferência ou manipulação do ambiente. Por conseguinte, observou-se fatores de exclusão social devido ao afastamento da população ribeirinha de centros urbanos, por exemplo, da Vila Permanente, bairro adjacente ao Rio Onze, que recebe coleta de lixo diária, esgotamento sanitário adequado e ruas pavimentadas em contraste com a comunidade ribeirinha que vive em condições precárias de saúde com ausência de coletas de resíduos sólidos e esgotamento sanitário, gerando uma desigualdade social. Esses fatores podem levar ao aparecimento de doenças agudas e o acometimento por inúmeras parasitoses, principalmente, às de veiculação hídrica que afetam os grupos mais vulneráveis, sobretudo as crianças. Sendo asism, a pesquisa retratou que que embora as comunidades ribeirinhas fossem amparadas e reconhecidas pelo Governo Federal, as exposições e vulnerabilidades  constantes geram um fator preocupante. Portanto, evidencia-se a necessidade de políticas públicas diligentes, enfatizando a coleta de lixo constante, esgotamento sanitário adequado e a prática de educação em saúde.
