Winter rape (1) Winter rapeseed area in the upper reaches of the Yangtze River. Including Sichuan, Chongqing, Guizhou, Yunnan and western Hubei. Fertilization principle (1) According to the soil fertilization results, determine the reasonable amount of nitrogen, phosphorus and potassium fertilizer; (2) The application of nitrogen fertilizer in different times, appropriate reduction of the application amount of nitrogen fertilizer, and the application of manure; (3) According to the soil available boron content, an appropriate amount of boron fertilizer; (4) Adding organic fertilizer, promoting the cooperation of organic and inorganic fertilizers, and increasing the strength of straw returning; (5) Adding alkaline fertilizer to acidified soil. 2. Fertilization advice (1) The production level is above 200 kg/mu: nitrogen fertilizer (N) 13~14 kg/mu, phosphate fertilizer (P2O5) 6~7 kg/mu, potash fertilizer (K2O) 5~7 kg/mu, borax 1.0 kg/mu; (2) Production level 150~200 kg/mu: nitrogen fertilizer (N) 10~12 kg/mu, phosphate fertilizer (P2O5) 4~6 kg/mu, potash fertilizer (K2O) 3~5 kg/mu, borax 0.75 kg/mu ; (3) Production level 100~150 kg/mu: nitrogen fertilizer (N) 7~9 kg/mu, phosphate fertilizer (P2O5) 3~4 kg/mu, potash fertilizer (K2O) 2~4 kg/mu, borax 0.75 kg/mu ; (4) The production level is below 100 kg/mu: nitrogen fertilizer (N) 5~7 kg/mu, phosphate fertilizer (P2O5) 2~3 kg/mu, potash fertilizer (K2O) 1~3 kg/mu, borax 0.5 kg/mu. 60% of the total nitrogen fertilizer is applied as base fertilizer, 20%~30% for wintering seedling fertilizer, 10%~20% for manure fertilizer; 60% potassium fertilizer for base fertilizer application, 40% for manure fertilizer; phosphate fertilizer and boron fertilizer for base fertilizer application. If the organic fertilizer is applied to the base fertilizer, the amount of chemical fertilizer can be reduced as appropriate; when the straw is returned to the field in the previous season, the amount of potassium fertilizer can be reduced by 1/3. (2) Winter rapeseed area in the middle and lower reaches of the Yangtze River. Including Anhui, Jiangsu, Zhejiang and most of Hubei. Fertilization principle (1) According to the soil fertilization results, determine the reasonable amount of nitrogen, phosphorus and potassium fertilizer, appropriately reduce the amount of nitrogen and phosphorus fertilizer, and determine the reasonable ratio of nitrogen, phosphorus and potassium fertilizer; (2) Deep application of transplanted rapeseed base fertilizer, direct seeding of rapeseed seed and fertilizer, concentrated application of fertilizer to improve nutrient utilization efficiency; (3) According to the soil available boron content, an appropriate amount of boron fertilizer; (4) Increase the intensity of straw returning to the field and promote the cooperation of organic and inorganic fertilizers; (5) Adding alkaline fertilizer to acidified soil. 2. Recommended formula and recommended recommendations for fertilization: 18-10-12 (N-P2O5-K2O, containing boron) or similar formulation. Fertilization recommendations: (1) The production level is above 200 kg/mu: the recommended dosage of formula fertilizer is 50 kg/mu, the wintering seedling fertilizer is applied with urea 5~8 kg/mu, and the manure fertilizer is applied with urea 5~8 kg/mu; (2) The production level is 150~200 kg/mu: the recommended dosage of formula fertilizer is 40~50 kg/mu, the wintering seedling fertilizer is applied with urea 5~8 kg/mu, and the manure is applied with urea 3~5 kg/mu; (3) The production level is 100~150 kg/mu: the recommended dosage of formula fertilizer is 35~40 kg/mu, and the fertilizer is applied 5~8 kg/mu of urea; (4) The production level is below 100 kg/mu: the recommended dosage of formula fertilizer is 25~30 kg/mu, and the fertilizer is applied 5~8 kg/mu. (3) Three-cooked winter rapeseed area. Including Hunan, Jiangxi and Guangxi. Fertilization principle (1) According to the results of soil testing and formula fertilization, determine the reasonable dosage and ratio of nitrogen, phosphorus and potassium fertilizer, and pay attention to the application of manure; (2) According to the effective boron content of the soil, the amount of boron fertilizer is supplemented; (3) 2 to 3 kg/mu of sulfur can be applied in the sulfur-deficient area. If other sulfur-containing fertilizers are used, the amount of sulfur can be reduced. (4) Increase the intensity of straw returning to the field and promote the cooperation of organic and inorganic fertilizers; (5) Adding alkaline fertilizer to acidified soil. 2. Recommended formula and recommended recommendations for fertilization: 18-8-14 (N-P2O5-K2O, containing boron) or similar formulation. Fertilization recommendations: (1) The production level is 180 kg/mu or more: the recommended dosage of formula fertilizer is 50 kg/mu, and the fertilizer is applied to urea 5~8 kg/mu; (2) The production level is 150~180 kg/mu: the recommended dosage of formula fertilizer is 40~45 kg/mu, and the fertilizer is applied 5~8 kg/mu of urea; (3) The production level is 100~150 kg/mu: the recommended dosage of formula fertilizer is 35~40 kg/mu, and the fertilizer is applied to urea 3~5 kg/mu; (4) The production level is below 100 kg/mu: the recommended dosage of formula fertilizer is 25~30 kg/mu, and the fertilizer is applied to urea 3~5 kg/mu.
