文摘内容 By the method of comparison and analysis, the succession pattern of total P, available phosphorus, organic P types and inorganic P types in rhizosphere and non-rhizosphere soil at different development stages in Larch (Larix olgensis) plantations was revealed. The result showed: when stand age increased, the content of available phosphorus, O-P, total P and organic P in rhizosphere soil decreased greatly or significantly,the content of inorganic P, Ca-P and Fe-P in rhizosphere soil in rhizosphere soil increased greatly or significantly. The content of Ca-P in non-rhizosphere soil increased with stand growing. The content of Fe-P in half-mature stand, available P and Fe-P in near mature stand, available P and Ca-P in mature stand in nonrhizosphere soil was more than that in rhizosphere soil。
