怎样才能实现高产稳产低成本?我们大队近几年来的生产实践证明,发展绿肥就是一条重要途径。一九七四年,第二生产队开始在四十亩麦田里套种了草木樨,秋季翻压后,第二年种植的谷子亩产三百八十一斤,比没有套种绿肥的增产25％。之后年年扩大绿肥面积,到一九七七年达到一千三百多亩,使现有耕地中有65％的面积用绿肥倒了一次茬,肥了一次地。大种绿肥带来了很多好处: How can we achieve high and stable output and low cost? Our production practice in recent years has proved that the development of green manure is an important way. In 1974, the second production team began to plant grass and mulch in forty acres of cornfield. After turning over in the autumn, the output of mounds per mu in the second year was 381 kilograms, 25% more than that of no intercropping green manure. . The area of ​​green manure will be expanded every year after that. By 1977, it will reach 1,300 mu, so that 65% of the existing cultivated land will be sprinkled once with green manure and fattened once. Large green manure has brought many benefits:
