堆肥占农村有机肥料的大部分,它是用作物秸秆、杂草、树叶、泥炭和垃圾等各种废弃物加上适当的人、畜粪尿沤制成功的。通过微生物的分解作用,使堆肥原料从植物不能利用的有机质态转变为有效的矿质养分态,同时形成一定量的菌体和腐殖质。为了提高堆肥沤制效果,除注意调节堆肥的水分、温度和通气状况外,还应搭配好堆肥的原料。
Composting accounts for most of the organic fertilizer in rural areas, and it is made by using various kinds of waste such as straw, weeds, leaves, peat and rubbish together with appropriate human and animal excrement. Through the decomposition of microorganisms, the composting material can be transformed from the organic matter that can not be used by the plant into an effective mineral nutrient, and at the same time, a certain amount of bacteria and humus are formed. In order to improve the compost system, in addition to adjusting the moisture, temperature and aeration of compost, it should be well compounded with the raw materials of compost.
