【摘要】 用外生菌根菌纯培养的固体和液体菌剂在田间落叶松、樟子松幼苗进行人工接种试验,以研究外生菌根菌对松苗猝倒病的生物防治效应。结果:1、兴安落叶松幼苗猝倒病的发病率比对照区降低14.01％～21.91％;樟子松幼苗猝倒病的发病率比对照区降低11.48％～20.26％。2、试验筛选出Suillus grevillei,Boletus sp.,Gomphidius rutilus,Russula foetens 等优良菌种。3、母种培养基以松针(浸膏)培养基、马铃薯葡萄糖麦芽汁琼脂培养基为最佳;原种培养基则以草炭(石至)石玉米粉葡萄糖松针(浸膏)培养基、草炭(石至)石MMN液培养基为最佳。更多还原

【Abstract】 The seedlings of Larix gmelini and Pinus sylvestris var. mongolica that grow in the field were inoculated with fungi that grow on solid and liquid culture medium. We conclude that: (1) The seedling damping-off disease rate of Larix gmelini and Pinus sylvestris var. mongolica are less than that of contrast; (2) Suillus grevillei, Boletus sp., Gomphidius rutilus, Russula foetens are the best vailable ectomycorrhizal fungi selected in this experi- ment; (3) Pine needle decoction and PDMA culture medium are the best cultures to maternal species.更多还原
