摘要
不同造林密度下杂种落叶松土壤细菌、放线菌和真菌的数量及随季节变化的动态规律的研究结果表明:细菌占微生物总量的99%以上,其次是放线菌,真菌数量最少;造林密度对杂种落叶松土壤微生物均有显著影响,其中,造林密度为3 300株/hm2的林分,土壤中微生物含量最高,最适合微生物的繁衍增殖。
Focused on the analysis of the number of the bacteria, actinomycetes, fungi and the seasonal dynamics of different afforestation density of Hybrid Larch. The results showed that： the bacteria account for 99% of the total amount of microorganism, followed by actinomycetes, fungi the least number. The effect of afforestation density on microbes was significant and the 3300 tree/hm2 was the most suitable density for microbial breeding.
