摘要
通过砂滤管和尼龙网袋法研究了有机物料在砂土的腐殖化和矿质化规律,对该土壤有机质培肥及调控提出了建议。研究表明:供试的几种物料总的分解速率趋势为:玉米秸杆>小麦秸杆>鸡粪>牛粪>猪粪。砂土有机质的矿化速率为3.06%;同时发现两种研究方式下,土壤有机质含量和活性有机质含量二者之间具有明显的相关性。
The decomposition of organic matters were studied by porous and nylon - bag experiment, and then organic matter management was suggested. The results showed that the decomposition rate of several tested organic matters was: maize straw 〉 wheat straw 〉 chicken manure 〉 cow manure 〉 pig manure. The results also showed that mineralization rate of organic matters in sandy soil were 3.06%. And the amounts of organic matter and labile organic matter (LOM) in sandy soils had the obvious correlation under two methods.
