我省夏季积造农家肥主要是用普通堆肥和沤肥方法,原料是秸秆、青棵、垃圾、草炭等有机物以及人畜粪尿和土等。1.普通堆肥.普通堆肥的性质基本与厩肥相类似,属于热性肥料。堆温不超过50℃,腐熟时间较长(3～4个月),堆肥中有机质含量较高,其成分以纤维素、半纤维素为主,还含有少量的蛋白质态氮,一般堆肥的碳氮比较大,分解较慢,但肥效持久。长期施用普通堆肥,可以起到增加作物产量和改良土壤的作用。
The summer harvest in our province is mainly used ordinary fertilizer manure and fat method, the raw material is straw, green tree, garbage, peat and other organic matter as well as human and animal waste urine and soil. 1.

The composting temperature is no more than 50 ℃, the decomposing time is longer (3-4 months), the content of organic matter in compost is higher, its composition is mainly cellulose and hemicellulose, and also contains a small amount of protein nitrogen, composting carbon Nitrogen is relatively large, slow decomposition, but fertilizer lasting effect. Long-term use of ordinary compost, can play a role in increasing crop yield and soil improvement.
