盆栽基质对AM真菌及宿主植物生长发育的影响

摘要

Under greenhouse conditions and Glomus mosseae as applied culture, the influences of growth mediums to the growth of arbuscular mycorrhizal fungi (AMF) and its host plant were studied in pot culture. The results showed that the influences of the black stone powder mixed with 1/3 amount of loam soil (Jl) on the growth of AMF and its host plant were the highest. Comparing to other growth mediums treatments, the infection rates of AM fungus in Jl treatment increased by 24.6% - 114.1%, number of spores by 12.9% - 65.6%, total dry weight of corn by 15.6% ~ 109.2%, and P concentrations by 9.1 % ~ 84.6%. The influences of sand mixed with 1/3 amount of loam soil (J5) on the growth of AMF and its host plant were the lowest. This research provided technical parameter for processing of the high quality AM production.%在温室条件下,采用盆栽法,以摩西球囊霉(Glomus mosseae]为供试菌种,以玉米(运单19号)为供试作物,研究了不同盆栽基质(J1,J2,J3,J4和J5)对AM真菌及宿主植物生长发育的影响.结果表明,基质J1(黑石粉与壤土体积比为3∶1)对AM真菌及宿主植物生长的影响作用最大,与其他处理相比,菌根侵染率提高24.6％～ 114.1％,孢子含量提高12.9％～65.6％,玉米总干质量提高15.6％～109.2％,磷含量提高9.1％～84.6％.基质J3(灰石粉与壤土体积比为3∶1)对AM真菌及宿主植物的影响作用次之,基质J5(细红砂与壤土体积比为3∶1)的效果最差.此研究为优质AM菌剂生产体系的建立提供了技术参数.
