栽培绿肥作物,能使土壤内有机质增加,提高肥力,还能改善土壤物理特性。我们曾于1957年在一块89亩的油菜茬地上,利用夏季土地体闲期,以每亩5斤播种量栽培黑豆绿肥:出苗后经过65日的生长,至7月28日翻耕时,每亩黑豆枝叶产量1834斤。播种小麦后,根据小麦苗期以至成熟前的田间观察,其发育情况与每亩施基肥12,000斤厩肥的对照区此较,绿肥地小麦生长表现优异。1958年夏收时这块小麦亩产302斤,比对照区亩产218斤高

Cultivation of green manure crops, can increase the organic matter in the soil, improve fertility, but also improve soil physical properties. In 1957, we cultivated black bean green manure on a 89-acre stubble field using the summer land-based leisure time at a rate of 5 kg per acre: After 65 days of emergence, till July 28, Mu black beans foliage yield 1834 kg. Wheat sowing, wheat seedling and mature field before the observation that its development and per hectare of base fertilizer 12,000 kg of manure compared to the control area, green manure wheat growth performance. In the summer of 1958, the yield of this piece of wheat was 302 pounds per mu, 218 kilograms more than the control plot
