摘要
对湖北省武汉市和老河口市的２个机械化垃圾处理场制作的垃圾堆肥的质量进行了测定与评价，并通过盆栽生物试验和大田取样调查方法对垃圾堆肥的肥力特征及其对土壤基本性状的影响进行了研究。结果表明，所有７个供试垃圾堆肥的全氮、全磷含量均达不到国家标准的要求，少数垃圾堆肥铅含量超标，武汉市的垃圾堆肥优于老河口市。垃圾堆肥在大量施用的情况下，具有一定肥效并能提高土壤养分含量，但其有效供肥时间短，长期连续施用可能引起土壤砂化和污染。
The quality of urban waste manures(UWM)was tested and evaluated which were produced in two mechanized urban waste manure-disposing yards in Hubei Province.The fertility characteristics of these manures and their effect on the soil basic properties were studied by the method of pot biological experiment and investigation sarnpling in field.The results showed that the contents of total N and total P in all of the seven urban waste manure sample could not reach the state standard,but the Pb content in a few of them exceeded the standard stipulatio. Manures made in Wuhan were superior to Laohekou′s.Urban waste manure had some nutrient function and fertilization effect on soil when applied in a large amount, but the period of effective supply of nutritions was short. And it may cause the soil to become sandy and contaminated if applied continuously for a long time. The agricultural application of UWM was also discussed in this paper.
