外生菌根菌剂在油松育苗造林中的应用

将工业液体发酵法生产的厚环乳牛肝菌固体菌剂与彩色豆马勃孢子粉剂，细菌菌剂及磷马以不同的模式进行组合。应用到油松容器育苗中，并将生长百天的菌根化油松苗在山西黄土高原造林。结果表明，将厚环乳牛肝菌与细菌混合接种并施磷肥效果最佳。接种菌根真菌并施肥的处理优于菌根真菌单接种的处理，单施肥处理优于驿照但不及其它处理。接种菌根真菌能促进苗木的生长，尤其是增加苗木的干重和对磷元素的吸收，提高造林成活率，并在...

APPLICATION OF COMMERCIAL ECTOMYCORRHIZAL INOCULA ON CONTAINER-GROWN CHINESE PINE SEEDLINGS USED FOR AFFORESTATION IN CHINESE LOESS PLATEAU

The commercial inoculum of Suillus grevillei which was produced with aliquid fermentor was inoculated onto the container-grown Chinese pine see-dlings, together with the spore slurry of Pisolithus tinctorius, bacteria inocu-lum and phosphate fertilizer in the different type of combinations. Havinggrown for only 100 days, the mycorrhizal seedlings were used for afforestationin Chinese Loess Plateau. The results of this 4-year-experiment showed thatthe optimum treatment was the combination of S. grevillei, bacteria andphosphate fertilizer, the treatment which was the combination of mycorrhizalfungi and fertilizer performed better than the one which used only mycorrhi-zal fungi, the treatment which used only fertilizer performed better thancontrol but was not as good as other treatments. It could be concluded thatmycorrhizal fungi could enhance the growth of seedlings, especially in dryweight and phosphate absorption, increase the survival rate of afforestation,continue to exert their abilities to accelerate the growth of seedlings in theafforestation sites after 3 years.
