摘要
在耐高磷营养的ＶＡ真菌初筛试验的基础上，对两株采自不同地区的摩西球囊霉（Ｇ．ｍｏｓｓｅａｅ）菌株，在不同施磷条件下进行盆栽试验，研究ＶＡ真菌对高磷营养的耐性，从中选出一株耐高磷菌株。
A pot culture study to select P-tolerant isolate of VA mycorrhizal fungi was conducted. Two isolates of Glomus mosseae, which were collected from Xinjiang and Beijing,were inoculated into soil samples of different P levels. Soybean was grown for 2 months. The results showed that isolate '93' had more tolerance to applied P. When the content of available P in soil inoculated with isolate '93' reached 150 ppm, the colonization rate in root did not decreased significantly and the content of total P in seedlings had an increase of 70% in comparison to uninoculated control seedlings.
