80年代以来,在研究油菜高产栽培的过程中,发现亩产200公斤以上的油菜,到秋末(11月底)植株绿叶达9～10片,叶面积指数1.5以上,越冬前(12月底)植株绿叶达12～13片,叶面积指数2.5以上,我们将这种油菜称为“秋发”生长型。经对比试验表明,秋发油菜亩产211.4～213.4公斤,比冬发油菜(冬前绿叶9～10片,叶面积指数1.5以上)亩产 Since the 1980s, in the process of high yielding rapeseed cultivation, rapeseed production over 200 kg per mu was found. By the end of autumn (the end of November), the number of green leaves reached 9 to 10 and the leaf area index was over 1.5. Before the winter (at the end of December) Up to 12 to 13, leaf area index above 2.5, we will call this rape as “autumn hair” growth type. The comparative tests show that the yield per acre of 211.4 ~ 213.4 kg, more than the winter cole (green leaves 9 to 10 before the leaf area index of 1.5 or more) per mu
