1980年我所60亩玉米草木樨间种试验田,实收玉米1,009斤/亩(按毛面积算),压草木樨绿色体1,166斤/亩.玉米与草木樨2:1间种,垄距1.9尺,玉米株距0.8尺;草木樨占1/3面积,一条垄种双行,实际等于种半亩草木樨.草木樨压青后,相当于给土壤增加223.4斤有机质,增施29.2斤硫铵和2.9斤过磷酸钙、4.7斤氯化钾,这样就可以改变土壤结构,调解土壤的水热气光条件,起到了养地作用,为来年增产打下了基础.
In 1980, 60 mu of maize mulberry plants were planted in an intercropping field, with 1,009 kg / mu of corn and 1,166 kg / mu of green body pressed with 1,009 kg of corn per mu. The ratio of maize to grasses 2: 1 was 1.9 Feet, corn spacing of 0.8 feet; grass mulch occupy 1/3 area, a ridge two lines, which is actually equal to half a mu of grass mulberry .Compression grass green pressure, equivalent to increase soil 223.4 kg of organic matter, 29.2 kg additional ammonium sulfate And 2.9 kg of superphosphate, 4.7 kg of potassium chloride, so you can change the soil structure, adjust the soil water and heat conditions, played a role in raising land for the coming year to lay a foundation for yield.
