摘　　要：以黄瓜为试材 ,用菜园土与河沙的不同配比及蛭石作为基质处理 ,接种丛枝菌根菌Glomusversiforme(简称GV)和不接种CK(接同样量的灭菌的沙土 )。结果发现丛枝菌根菌的侵染率在菜园土与河沙不同配比处理中较高 ,为 48.48%～ 5 6 .15 % ,蛭石处理的侵染率较低 ,为 37.82 %。基质处理 2 (菜园土∶河沙 =1∶2 )的丛枝菌根促生效果最显著 ,与对照比在叶面积、干物质量、壮苗指数上 ,分别提高 44 .0 9% ,36 .46 %和 83.6 2 % ,是黄瓜菌根化育苗的理想基质。此外 。The substrate treatments were the mixture of soil/sand (1∶0,1∶2,1∶4) and vermiculite. Cucumber seeds were sown with Glomus versiforme and CK. The results showed the infectionrates of GV were 48.48%-56.15% in mixture of siol and sand, was 37.82% in vermiculite. The most significant beneficial effects of GV are in substrate treatment No.2 (soil/sand=1∶2),which increased leaf area,dry weight and index of health seedling up to 44.09%,36.46% and 83.62% as compared with CK respectively. Therefore substrate treatment No.2 was the best substrate with inoculation of mycorrhiza for cucumber seedling growth. In addition inoculation of GV in soil also increased the growth of cucumber seedlings.
