摘要/Abstract

摘要： 以玉米为材料,利用三室隔网培养方法,研究了缺P土壤上施用植酸和卵磷脂时接种几种菌根真菌(Glomus mosseae, Glmous versiformea, Gigaspora margarita)对根际土壤酸性磷酸酶和碱性磷酸酶活性的影响.玉米生长70d后,收获测定距根表不同距离土壤中的磷酸酶活性.结果表明,接种菌根真菌增加了根际土壤酸性和碱性磷酸酶活性,Gigaspora margarita菌根菌的作用大于其它2个菌根菌.不同P源对磷酸酶活性有明显影响.

关键词: VA菌根, 玉米, 酸性磷酸酶, 碱性磷酸酶

Abstract: The effect of VAM fungi on phosphatase activity in maize rhizosphere was examined by pot culture experiment,in which,three-compartment-pots were used,the central compartment being separated from the outer two by a nylon net with 30μm mesh.Plants were harvested 70 days after planting.Soil acid and alkaline phosphatase were measured at different distances from root surface.The results showed that VAM increased the activities of soil acid and alkaline phosphatase in the rhizosphere.It was found that different phosphorous sources had different effects on phosphatase activity.

Key words: Vesicular-arbuscular mycorrhizal, Maize, Acid phosphatase, Alkaline phosphatase
