通过对广西龙胜里骆林区不同林龄杉木幼林和间种黄豆的杉木幼林土壤微生物及生化特性的分析测定表明,3龄杉木幼林土壤微生物数量最高,生化活性较强。间种黄豆的杉木幼林土壤细菌和放线菌数量以及生化活性强度明显高于纯幼林。显示了3龄幼林和间种黄豆的幼林土壤微生物较活跃,具有较高肥力和森林生产力。
According to the analysis of soil microbe and biochemical characteristics of young Chinese fir plantations with different ages and different seasons in Longsailili village of Longsili, Guangxi, it shows that the soil microbial population and the biochemical activity of the young Chinese fir plantation are the highest. The number of soil bacteria and actinomycetes and the biochemical activity of young seedlings of Chinese fir grown on soybean were obviously higher than those of pure young forest. The results showed that the young microbes in the 3rd and 5th seedlings were more active soil microbes, with higher fertility and forest productivity.
