摘　　要：研究结果表明：垃圾堆肥具有促进作物增产的作用，并不会引起重金属污染。但在北方潮土地区，垃圾肥施用量以４０～５０ｔ·ｈｍ－２·茬－１为宜。过量施用垃圾肥不仅会引起施肥经济效益明显降低，且会引起土壤砂化。研究还表明，粘质土壤对垃圾肥有更大的容纳量。Experimental results showed that refuse compost could increase yield of crops and could not cause heavy metal pollution. The optimum applying amount of refuse compost is about 40～50 t. hm-2. crops-1 in the moist region of northern China. Over application of the compost could not only obviously reduce the economic benefit of the compost, but also lead to formation of sandy soil. Clay soil could accept large number of refuse compost.
