本文采用室内培养法和田间埋设玻璃滤纸包法研究了粉状畜禽粪便堆肥和颗粒堆肥的养分释放。结果表明,粉状堆肥经颗粒化处理后,养分释放速度变缓,适合在生长期较长的农作物上施用。在一个生长季中牛粪、猪粪和鸡粪颗粒堆肥N素释放率分别为30～35%,35%～45%和45～55%,但其中60～80%的N素释放主要集中在施用后的前二个月内。

In this paper, the indoor culture method and field buried glass filter paper bag method to study the powder manure composting and particle composting nutrient release. The results showed that after the compost of the powder compost, the nutrient release rate slowed down and was suitable for application in the crops with longer growing period. In a growing season, the N release rate of cow manure, pig manure and chicken manure composting was 30-35%, 35% -45% and 45-55%, respectively. However, 60-80% of the N released mainly concentrated in Within two months after application.
