Abstract: FIELD: apiculture, in particular, beehive construction. SUBSTANCE: hive has n-individual sections composed of casing including two pairs of walls arranged in mutually perpendicular relation and flanges for mounting of comb frames, detachable bottom defining in conjunction with casing walls bee-entrance windows and section roof. Bee-entrance windows are arranged at four sides of section in plane extending in parallel with section bottom and directed toward slots, which define arrival sites. Section bottom is provided with central and side recesses for receiving of central and side plates. Plates are beveled at their one side and are provided with cavities formed in their other side for defining feed accommodating slots, when position of plates is altered through 180 deg relative to recesses. To assemble hive, plates are removed, sections are coupled to one another with their side surfaces and secured by means of catches positioned on ends of pins. As a result, side recesses are aligned with respect to one another to define single channel-shaped space inside hive. Apparatus for creating microclimate with predetermined parameters inside hive may be joined to said channel-shaped space in hive. Hive of such construction allows microclimate with predetermined parameters to be created in all hive sections, prophylactic treatment of all bee families to be carried out simultaneously without necessity for removal of bee families from their sites, and comfortable conditions to be provided during prolonged transportation under high density conditions. EFFECT: increased efficiency and simplified construction. 8 cl, 13 dwg

Abstract: Изобретение относится к сельскому хозяйству и может быть использовано при прогнозировании урожая и качества зерна, а также оценки эффективности проводимых агротехнических мероприятий и сроков их проведения. Способ включает оптимизацию сроков посева, уточнение норм высева и способов посева. Для этого сначала определяют по среднестатистическим данным сумму среднесуточных температур в пределах 526... 694° С. По этой величине устанавливают срок начала высева семян, но не раньше 60 и не позже 44 суток от момента посева до прекращения вегетации. Контролем правильности выбора сроков посева служит наличие трех-четырех стеблей на каждом узле кущения и с достаточным запасом сахаров для устойчивости растений к минусовым температурам в диапазоне 18-20° С. Расчетом устанавливают величину гидротермического коэффициента (ГТК). При ГТК в пределах до 0,5 норму высева семян уменьшают на величину 10-15%. Ширину междурядий устанавливают равной 22,5 см. При ГТК в диапазоне 0,5-0,9 норму высева семян сохраняют. При этом ширина междурядий в посевах - 15 см. При расчетном значении ГТК больше 0,9 норму высева семян увеличивают на 20... 25%. Ширину междурядий при рядовом способе посева устанавливают равной 7,5 см. При той же урожайности в зерне озимых культур содержание белка увеличилось на 2,8-3,0%, а клейковины - на 6,7-8,4%. Потенциальную урожайность устанавливают из выражения: у=к 1 · а· х 2 +к 2 · в· х -1 +к 3 · с -1 , где у - ожидаемая урожайность, кг/га; а - норма высева, штук/га; в - сумма положительных температур от даты посева до устойчивых отрицательных температур, ° С; с - ширина междурядий, м; х - длительность посева в днях от рекомендуемых сроков, сутки; к 1  - коэффициент пропорциональности, учитывающий сортовые качества каждого семени в накоплении зерновой массы, к 1 =(0,6... 0,8)· 10 -3  (кг· сутки 2 )/штук; к 2  - коэффициент пропорциональности, учитывающий влияние температурного режима на формирование корневой системы растений, к 2 =(0,0512... 0,0934)· 10 4  кг· сутки/(° С· м 2 ); к 3  - коэффициент пропорциональности, учитывающий размещение растений на поверхности поля; к 3 =(0,00007... 0,00015)· 10 4 , кг/м. При устойчивых запасах почвенной влаги в посевном слое О... 12 см предлагаемый способ с надежностью 0,90... 0,95 обеспечит получение расчетной урожайности в последующем году.
