采用尼龙袋法,研究酸性土壤施用4种豆科绿肥(尖叶木蓝、铺地木蓝、扁豆与链荚豆)后,在1年内不同时间,土壤无机磷各组分含量的动态变化。结果表明:不同绿肥对于土壤无机磷影响的效果存在显著差异,但总体上施用豆科绿肥可显著降低酸性土壤无机磷的总量,对于土壤无机磷各组分,施用绿肥可显著增加土壤铁磷(Fe-P)以及铝磷(Al-P)的含量,但显著降低土壤中钙磷(Ca-P)以及闭蓄态磷(O-P)的含量;施用绿肥对于土壤无机磷的影响随施肥时间的变化而不同。 The nylon bag method was used to study the dynamic changes of soil inorganic phosphorus contents in acidic soils after applying four kinds of leguminous green manure (Phyllostachys pubescens, Phoebe bournei, lentils and pods) at different times within one year. The results showed that there were significant differences in the effects of different green manures on soil inorganic phosphorus. However, the application of leguminous green manure could significantly reduce the total amount of inorganic phosphorus in acidic soils. The application of green manure to soil inorganic phosphorus significantly increased the contents of iron-phosphorus (Fe-P) and Al-P (Al-P), but significantly decreased the contents of Ca-P and OP in the soil. The effects of applying green manure on soil inorganic P The difference is different.
