城市生活垃圾堆肥对土壤农化性状的影响

THE EFFECTS OF REFUSE COMPOST FROM URBAN SOURCES ON THE AGRICULTURAL CHEMICAL PROPERTIES OF SOIL

利用城市生活垃极堆肥作为肥料进行了土壤盆栽水稻和小麦的试验。试验结果表明,土壤中N、P、K、Si、有机质和矿质成分明显地增加,土壤的酸度和粘滞性显著下降,提高了土壤的透气性,同时土壤中的酶活性也有一定的改变。

Urban refuse composts utilized as fertilizer has been studied on effects of soil by rice plant and wheat pot - cultivated experiments. The results show that N,P, K,Si,organic matter and mineral compositiom in soil increased, soil acidity and viscidity decreased, permeability of soil increased , enzyme activities of soil changed.
