近几年来,耕地不断增加,复种面积迅速扩大,肥料供应很感不足.发展绿肥是解决肥料问题最经济有效的办法,特别是复播短期绿肥,既不占地,又能很快地生产大量绿色体作为肥料,省工、省费,比割草沤肥的成本还低.一九六五年,我们在哈拉塔公社多浪管理区第一大队三个生产队的麦茬地复播绿豆、油菜作绿肥,到九月中旬翻耕时,亩产鲜草4,000斤.而每亩成本仅0.7—0.8元,还可大量节约积肥运肥劳畜力,加快秋播进度.复播绿肥要注意下面几个问题:1.选地:复播绿肥生长期短,一般不施肥料,必须选择较肥沃的土地,否则生长不好,
In recent years, increasing arable land, rapid expansion of the area of multiple cropping, lack of fertilizer supply.Development of green manure is the most economical and effective way to solve the problem of fertilizer, especially the short-term green manure replanting, neither occupy land, but also quickly produce large quantities In 1965 we reprocessed mung beans at the stubble of the three production teams of the First Brigade of Halata Commune in Longlang Commune, Rape as green manure, tillage by mid-September, per mu yield 4,000 kg of fresh grass, while the cost per acre is only 0.7-0.8 yuan, but also a large number of savings in fertilizer and labor force to speed up the autumn sowing progress. Several questions: 1. Election: Multicropping green manure growth period is short, the general fertilizer, must choose more fertile land, or poor growth,
