| Abstract: | [中文摘要]：以内蒙古锡林郭勒羊草(Leymuschinensis)草原为对象,研究了割草频率对土壤微生物数量和植物地下生物量的影响。结果表明,经过17年的割草,土壤微生物的数量和植物地下生物量均随割草频率的增加而降低。根据割草频率的土壤微生物数量和植物地下生物量的变化,提出较为合理的割草频率是割1年休1年,其次是割2年休1年。但是,多年围封不割草,不仅造成大量牧草资源的浪费,也削弱了微生物在土壤养分转化过程中的作用。
[英文摘要]：The study showed that through 17 years of mowing,the soil microbial quantity and underground plant biomass in the Xilinguole Leymus chinensis steppe of Inner Mongolia were decreased with increasing mowing frequency. Based on the variation of soil microbial quantity and underground plant biomass under effects of mowing frequency,it was suggested that one year cutting and one year no cutting,or two years’ cutting and one year no cutting would be the more reasonable mowing frequency,while fencing too many years would not only lead to the waste of pasture resources , but also weaken the effects of soil microbes on soil nutrients transformation. |
