In conclusion, rapeseed is a large number of crops that need NPK nutrients, and the absorption of nutrients and the accumulation and consumption of various organs in different growth stages are not the same. Therefore, only in accordance with the laws of need of fat rape, continue to meet the nutritional needs of its growth and development in order to achieve high yield. Improving fertilization technology is the main means to achieve this goal. (1) Effect of Cooperating Application of Farming Fertilizer and Chemical Fertilizer According to the results of the pilot application of combined fertilization with chemical fertilizer in 1981, that is, the output of each treatment in Table 6,
