摘要： 研究了盆栽培养后处理方式、宿主种植密度和农药对Glomusmosseae生长繁殖的影响,结果表明,后处理A和后处理B的处理方式均可促进孢子的形成,以高粱为宿主的产孢量分别比对照提高90.9%,54.5 %,三叶草为宿主则分别提高 61.5 %,7.7%杀菌剂利得不利于G.mosseae繁殖体的形成,施后产孢量仅为对照的 47.6 %,杀菌剂代森锰锌对生长繁殖影响不大.试验所设的在体积为9600cm3的容器里高粱的 4个种植密度中,7和14棵的处理更有利于G.mosseae孢子的产生。

Abstract: Up to now,pot culture is the common method for producing AM fungi inoculum.Some factors can affect the quality of inooulum .In this paper, the effects of post-treatment,fungicide and planting density on the quality of inoculum of G.mosseae were studied. The result showed that the effect of post-treatment was abvious.In Sorghum vulgate Per,compared to the control, the post-treatment A and the post-treatment B increased spore number by 90.9% and 54.5%respectively.Spore development decreased 47.6% by fungicide Lide, while the other fungicides hacl no obvious influence on G.masseae growth .The experiment on planting density indicated that the spore number of 7 or 14 sorghums/9600 cm3 was greater than 21 or 30 sorghums/9600 cm3.
