国家自然科学基金项目“茶树根际土壤铝、磷形态特征及其相互作用机理”（41071204）；

本校为第一机构

以茶树(Camellia sinensis)根际和非根际土壤为研究对象,选取湖南省石门、临澧、桃源、长沙、安化、资兴等6县(市)的茶园为采样点,对其根际和非根际土壤的全磷、有效磷及无机磷的不同化学形态进行了分析。结果表明,茶树根际土壤全磷和有效磷含量均高于非根际土壤,有效磷在根际富集明显;土壤无机磷含量及占全磷的比例差异都很大。不同母质发育土壤的无机磷组成也不同,板页岩母质发育的根际土壤中A1—P含量最高,Fe—P其次,O—P最少。花岗岩和第四纪红色黏土发育的根际土壤Fe—P最高,A1—P其次,O—P最少。3种母质发育的非根际土壤中均为Fe—P含量最高。根际无机磷中的 A1—P,Fe—P和Ca—P含量与有效...

The characteristics of soil total phosphorus（P）, available P, different chemical form of inorganic P were studied in rhizosphere and non-rhizoshpere soil that was collected from Shimen, Linli, Taoyuan and Changsha area in tea plantation. The results showed the content of total P and available P were higher in rhizosphere soil than non-rhizosphere soil, and the apperent enrichment of available P was observed, while the difference was greater in the content of inorganic P, the ratio of available P to total P in tea plantation soil. In the rhizo...
