分别以R、S代表植物根际、非根际土壤微生物数量,一般植物(或作物)的细菌R/S比例均为5-20.本研究结果表明:雅连的细菌R/S是0.82±0.38,表明雅连根际细菌受到了其根系分泌物的明显抑制,这可能是造成黄连连作障碍的原因之一.
Respectively R, S on behalf of the plant rhizosphere soil, non-rhizosphere soil microorganisms, the general plant (or crop) bacteria R / S ratio is 5-20.The results show that: Ya Lian bacteria R / S is 0.82 ± 0.38, indicating that the yaron rhizosphere bacteria were significantly inhibited by its root exudates, which may be caused by Coptis one of the reasons for the obstacle.
