为了探究不同种养模式对油茶林地土壤磷素含量的影响，对油茶林下养鸡、林下种草、间种花生和间种大豆4种林下种养模式下林地土壤磷素形态变化和含量进行研究。结果表明：不同模式下油茶林地根际土壤中有效磷含量显著高于非根际土壤，显著提高0～20 cm土层中有效磷含量，其中间种大豆的效果最显著；林下养鸡和林下种草显著提高油茶林地根际土壤和非根际土壤中全磷含量，间种花生和间种大豆对其影响不显著；不同模式下Al-P和Fe-P的含量均显著高于O-P和Ca-P，其中林下种草能显著提高根际Ca-P含量。

In order to explore the effects of different interplanting and breeding modes on the contents of phosphorus inCamellia oleiferaforest soil, forms and contents of phosphorus in C. oleiferaforest soils were analyzed at four kinds of inter planting and breeding modes, including raising chicken, sod culture, intercropping peanut and intercropping soybean in forest. The results showed that, under different planting and breeding modes, available phosphorus content in rhizosphere soil ofC. oleifera forest was signiifcantly higher than that in non rhizosphere soil, and could signiifcantly improve the ...
