本研究通过连续三年多点、多因子的田间试验、示范,杂交油菜秦油2号栽培技术模式已基本制定成功。内容包括:选定氮、磷、钾以及微肥配合用量比例(N:P_2O_5:K_2O=1:0.4:0.3),提出适宜播期、合理密度、科学管理方法等。研究结果经大面积示范推广,证明模式适宜,经济效益显著,一般平均亩增油菜籽25公斤。 In this study, we successfully established the technical model of rapeseed Qinyou No.2 through three years of multi-point and multi-factor field experiments. The contents include: selecting the proportion of N, P, K and trace fertilizer (N: P_2O_5: K_2O = 1: 0.4: 0.3), and put forward the suitable sowing date, reasonable density and scientific management methods. The results of large-scale demonstration of the promotion of the model to prove appropriate mode, significant economic benefits, the average increase of 25 acres of rapeseed oil.
