采用盆栽,对花生不同连作年限的土壤及花生根际微生物区系进行了培养计数,结果表明,随着连作年限的增加,土壤及根际的真菌数量显著增加,细菌和放线菌显著减少,根际土壤中的芽孢细菌显著增加。
The results showed that the number of fungi in soil and rhizosphere increased significantly and the number of bacteria and actinomycetes significantly decreased with the increase of continuous cropping years. Bacilli in the rhizosphere soil increased significantly.
