Although the enthusiasm of the majority of farmers to grow rapeseed is high, some ethnic species are numerous, chaotic, and miscellaneous; others are even planted and planted, and rape cannot grow and develop normally; in addition, there are problems with white seeding and applying nitrogen fertilizer. These are taboos for rapeseeds. To this end, attention should be paid to the following points: Select good quality rape varieties. That is, high oil production, low erucic acid content, and low glucosinolate content in the cake. The newly launched "Double Low" varieties include Zhongyouza No.2, Zhongyouza No.4, Zhongshuang No.6 and Zhongshuang No.7, as well as a series of new varieties such as Huaza, Ningza, Xiangza, Noza, and Youyan. . All localities should choose to plant 1-2 varieties according to the local ecological environment and planting habits. Rotation should be implemented for planting rapeseed. Even the earthworms have reduced the soil fertility as a whole, resulting in the shortage of certain elements and intensified diseases, resulting in a reduction of production by 10-15%. Therefore, in the last year, a field of rapeseed was planted and it was necessary to plant crops in autumn. Reapply base fertilizer and fertilize years ago. The high yield of rapeseed must catch autumn and winter crops, producing 100 kilograms of rapeseed, it needs to absorb pure nitrogen 8.8-11.3 kilograms, phosphorus pentoxide 3.0-3.9 kilograms, potassium oxide 8.5-10.1 kilograms, boron 0.5 kilograms; 70% Apply Base Fertilizer and Fertilizer before.
