摘要
盆栽试验结果表明城市生活垃圾堆肥施入紫色土中，可增加土壤的氮肥潜能，降低作物中Ｈｇ、Ｃｒ、Ｐｂ的含量；但施量过大会影响作物生长，造成作物减产，品质下降。本次土培试验初步提供了紫色土和垃圾的较适比为１∶１。
The results of pot experiments showed that application of composted domestic refuse could lead to increase of N fertilizer potential of purple soil and reduction of Hg,Cr and Pb contents of crops;however,excessive dose influenced crop growth,brought about decline of crop yield and quality.The suitable rate of purple soil to refuse 1∶1 was primarily proceeded.
