以农田栽参主要土壤类型白浆土为研究试材,采用盆栽的方式,根据白浆土田间持水量的40%、60%、80%分别设置低、中、高水分处理组,采用Biolog微平板法和化学方法研究水分对土壤微生物代谢功能多样性和土壤状况的影响。结果表明:在高水分处理下(白浆土相对含水量为80%),物种丰富度指数、AWCD值和碳源利用丰富度指数最高;土壤速效磷含量显著高于其它水分处理,同时土壤酶活性较高,对人参生长发育有利。
The main soil types of white soil soil were planted in potted soil. The low, medium and high water treatment groups were set according to 40%, 60% and 80% Effects of soil moisture on metabolic functional diversity and soil conditions of soil microorganisms by plate method and chemical method. The results showed that species richness index, AWCD value and carbon source utilization index were the highest under the high water treatment (white soil soil relative water content was 80%); soil available P content was significantly higher than other water treatments, High activity, beneficial growth and development of ginseng.
