摘要
在涪陵茎瘤芥(榨菜)根肿病常发重病区,进行了该病可控栽培因子和化学药剂防治的控害技术研究。结果表明:自然感染条件下,适当推迟播栽期,异地培育无菌壮苗,调节土壤pH值至8.0左右,移栽时立即用杀菌剂灌根等技术,可有效控制茎瘤芥(榨菜)根肿病的发生危害。其相对防效达70%左右。
In Fuling area where club-root of tumour mustard occured,a study of its controlling by cul -tivation and chemicals was made.The results showed that in natural infection condition,properly postpon-ing sowing,raising disease-free strong seedling,adjusting soil pH to about 8.0and promptly irrigating root with bactericide could control club-root effectively.Relative controlling effect arrived about 70%.
