不同营林方式对杉木幼林生长及土壤微生物数量的影响

Effect of different afforestation measures on Chinese fir growth and soil microbial quantity

对不同营林方式的杉木幼林生长量及土壤细菌、真菌、放线菌的数量进行了研究。结果表明:不炼山、定植2年生容器苗、造林后免抚育的生态型模式,相比炼山、定植1年生裸根苗、造林后抚育三年的传统型模式,杉木幼株生长量没有显著性差异;生态型营林方式减少了对微生物的破坏,且有利于微生物数量的恢复,建议在生产中推广生态型营林方式。

Under the different ways of afforestation, the Chinese fir young forest growth and the number of soil bacteria, fungi and actinomycetes were researched. The results showed that, the ecological mode of without controlled burning, 2-year-old container seedling and without tending, compared with the traditional mode of controlled burning, 1-year-old bare-rooted seedling and tending three years after afforestation, the Chinese fir young growth had no significant difference. The ecological mode reduced the damage to the microbial, and was beneficial to the recovery of microbial quantity. It is suggested to promote the ecological forest mode.
