最近几年,郧阳地区以间作套种为主的耕作制度发展很快,夏粮预留行面积迅速增加到100多万亩,对抗灾增产起了很大作用。要使这一改革发挥更大的增产作用,一个重要方面就是发展粮肥间套,以解决肥料矛盾和提高地力,从而提高各熟的单产。充分利用预留行种绿肥,是当前增加有机肥料的一个主要途径。它的增产效果十分显著。从全地区范围看,预留行绿肥一般亩产千斤,不
In recent years, the farming system dominated by intercropping has been developing rapidly in Yunyang. The reserve area for summer grain has rapidly increased to more than 1 million mu, which has played a significant role in increasing output. An important aspect of this reform to play a bigger role in boosting production is to develop a fertilizing system to solve the contradictions of fertilizers and enhance the fertility so as to increase the yield of cooked crops. Making full use of reserved green plants is one of the main ways to increase organic fertilizers. Its yield increase effect is very significant. From the perspective of the whole region, reserve green manures generally yield a thousand pounds, no
