摘要
苗圃预防试验结果表明，粉锈宁可有效地防治花椒苗期根腐病，经处理后的苗圃发病率为对照的１／１７。不同立地类型移栽试验显示，新垦山地及在耕地中的砂土、砂壤土较适宜花椒生长，不易感染根腐病。成年椒园根腐病的治疗效果，以粉锈宁灌根方式较好，并与施药剂的次数有关，在此基础上，本文结合病害流行条件与花椒栽培布局结构的关系，初步探索出预防和治疗根腐病害的综合措施。
Triadimefon was effective in controlling the root rot on Chinese prickly ash in nursery ex- periments. The . incidence of the seedling disease was only 1/17 the contrast with triadimefon treatment in seedling period. lt was indicated through replantion trials of the different soil types that the plant was appropriate to growing in the newly-cultivated soil or the sands and the sand loam of the agricultural cultivated land without being infected by the disease. On the basis of the trials , in the paper a set of integrated control measures were discussed on precautioning and curing the disease in combination with the epidemic conditions of the disease and the cultivated distribu- tion structure of Chinese prickly ash.
