| 摘 要： | Known as North Fir, Olga Bay Larch (Larixolgensis) is the most important afforestation speciesin Northeast China, and one of the best fast-growingand high-yielding species among coniferous speciesin the north. However, numerous researches indicatethat there is a deterioration tendency to various degreesin the quality of soil in the forest land of larchplantations (Asada Sutao,1981; Wang Xiushi, 1982;Zhang Huiliang, et al., 1987; Liu Shirong, et al., 1993;Yan Deren, et al., 1997; Pan Ji…

| Abstract: | 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 developmentstages in Larch (Larix olgensis) plantations was revealed. The result showed: when stand age increased, thecontent 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 orsignificantly. 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 non-rhizosphere soil was more than that in rhizosphere soil. |
