title: 红壤区双季稻田长期施肥定位试验1981-2020年水稻产量性状及关键物候期数据集

description: This dataset consists of 3 tables, which are:1. "Yield and critical phenological period" table, including the annual yield of rice in Jinxian red soil paddy field with single application of nitrogen fertilizer (N), single application of phosphorus fertilizer (P), single application of potash fertilizer (K), application of nitrogen-phosphorus fertilizer (NP), nitrogen-phosphorus-potassium fertilizer (NK), nitrogen-phosphorus-potassium fertilizer (NPK), twice nitrogen-phosphorus-potassium fertilizer (NPK2), fertilizer-organic fertilizer (early rice), pig manure in late rice), and no fertilizer (CK), etc. in nine treatments, from 1981 to 2020. Ziyunying, late rice pig manure) with application (NPKM), no fertilizer (CK), and other 9 treatments of rice annual output, early and late rice sowing period, transplanting period, the beginning of the spike period, spike flushing period, maturity, fertility monitoring data, a total of 15 fields, a total of 360 pieces of data, the amount of data 43.8KB.2. "Experimental site information" table, including the name of the experiment, geographic location, representative description, surrounding environment and site selection, altitude, slope, soil parent material, climatic conditions, animal activities, human activities, field management records, a total of 10 fields, a total of 1 data, data volume of 19.5KB.3. "Experimental design" table, including the year of the experiment, the varieties of early and late rice in different years, variety information, and the amount of N, P, K and organic fertilizer used in each year from 1981 to 2020, with a total of 14 fields, a total of 12 data entries, and a data volume of 23KB.
