绿肥是良好的有机肥料。据化验,每千斤绿肥,一般含有机质200斤,相当于硫铵20斤、过磷酸钙10斤、硫酸钾7斤。施用绿肥不仅能供给作物生育所需要的氮、磷、钾养分,而且还能给土壤增加大量有机质,有效地改良和培肥了土壤。夏季,气温高,湿度大,杂草繁茂,沤肥原料多,是突击沤制绿肥的大好时机。我们应抓紧时机,结合田间管理,发动群众,大量收集杂草,大沤绿肥,为夺取农业全面丰收积攒更多的有机肥料。
Green manure is a good organic fertilizer. According to the test, every kilogram of green manure, generally contains 200 kilograms of organic matter, equivalent to 20 kg of ammonium sulfate, superphosphate 10 kg, potassium 7 kg. The application of green manure can not only supply nitrogen, phosphorus and potassium nutrients required for crop growth, but also can increase a large amount of organic matter to the soil and effectively improve and fertilize the soil. Summer, high temperature, humidity, lush weeds, fertilizer and more raw materials, is an excellent opportunity to assault green tea manure. We should seize the opportunity to combine farmland management, mobilize the masses, collect large quantities of weeds and large green manure, and accumulate more organic fertilizers to seize the full harvest of agriculture.
