吉林西部地区土壤微生物区系初探

A Primary Study on the Soil Microflora in Western Jilin

本文通过对吉林省松原市三义乡二屯村、扶余县容家沟镇、大安市东方红农场、镇赉县岔台村四个地区土样分析,结果表明,四个地区土壤微生物的数量之间有明显差异,细菌数量最多,占微生物的总量的70%以上,在1.89×108cfu/g^5.72×108cfu/g之间,放线菌在2.10×107cfu/g^7.85×107cfu/g之间,真菌最少,在1.74×105cfu/g^6.92×106cfu/g之间;扶余县容家沟镇耕地土壤的性质较好,镇赉县岔台村土壤的恶化程度较高。

The soil microorganisms are extremely important for soil component parts.We analyzed more than ten samples of soil,which are collected from the following four areas-the Ertun village of Sanyi town and Rong Jiagou town of Fuyu county in Songyuan City,Dong Fanghong Farm of Da'an City and Chatai village of Zhenlai county in Baicheng.It shows that there is obvious difference in the quantity of the soil microorganisms from the four areas.The number of bacteria is the most,over 70%,1.89×108cfu/g～5.72×108cfu/g in ...
