- 摘要:
- 选择绥化地区现存羊草草地为研究对象，比较了围栏内外不同植物群落的土壤微生物数量变化趋势。结果表明：无论围栏内外，土壤三大类微生物数量以0～15 cm高于15～30 cm，围栏内微生物数量显著大于围栏外；真菌和细菌无论在围栏外还是围栏内在不同植物群落中的分布规律相似，真菌的分布为:羊草群落>杂类草群落>碱茅群落，细菌的分布为:杂类草群落>羊草群落>碱茅群落;放线菌的分布在围栏内外稍有不同，在围栏内:羊草群落>杂类草群落>碱茅群落，在围栏外：杂类草群落>羊草群落>碱茅群落。围栏内外三类微生物数量表现为放线菌数量最大,真菌次之,细菌较少。
- Abstract:
- Choosing the Leymus chinensis?steppe of abandoned field as object,the change tendency of soil microorganism population(fungi,bacteria and actinomycetes)in and out of the fence was compared.The results showed that:no matter inside or outside the fence,three types of soil microorganism quantity in 0 ~ 15 cm soil layer were higher than those of in 15~30 cm soil layer,and soil microorganism quantity inside the fence were higher than those of outside the fence;Bacteria and fungi whatever inside or outside the fence,the distribution law in different plant communities was similar,the distribution of fungi:Leymus chinensiscommunity>Weeds community>Puccinellia tenuifloracommunity,the distribution of bacteria for:Weeds community>Leymus chinensiscommunity>Puccinellia tenuifloracommunity;The distribution of inside and outside the fence of actinomyces were slightly different,inside the fence:Leymus chinensiscommunity>Weeds community>Puccinellia tenuifloracommunity,outside the fence:Weeds community>Leymus chinensiscommunity>Puccinellia tenuifloracommunity.Three kinds of microorganism quantity performance both inside and outside the fence for the largest number of actinomyces,second fungi,bacteria was the least.
