一、夏播绿肥 我县1957年试种麦茬绿肥成功,1959年扩大到公社试种,1960年各公社播种面积达10,981亩。据县良种繁育场核算:绿肥每亩成本是2.8元,能收鲜草1,000公斤左右（不包括地下根部分）;施用绿肥能省去运肥和施肥的费用,并且后效较好。绿肥增产的效果也很显著,如县良种繁育场有130亩麦田,种绿肥前一年,小麦亩产240斤,种绿肥后一年（配合其他生产技术）,亩产则达410斤,增产70.8％。 通过县良种繁育场的两年试验,初步找到了当地种麦茬绿肥较好的种类（表1及表2）。
First, the summer sowing green manure County in 1957 trials of stubble green manure success, in 1959 to expand the commune trial planting, communes in 1960 sown area of 10,981 acres. According to county seed breeding farm accounting: green manure cost per acre is 2.8 yuan, can receive about 1,000 kg of fresh grass (not including the underground part); application of green manure can save the cost of fertilizer and fertilization, and better after-effects. The effect of increasing green manures is also remarkable. For example, there are 130 mu of wheat fields in the county seed breeding farms. In the year before planting green manure, 240 mu of wheat was mu per mu, and one year after planting green manures (with other production techniques) 70.8%. Through the two-year trial of the county elite seed breeding farms, the better species of local green stubble stubble was found (Table 1 and Table 2).
