摘要
采用宏观调查方法,研究了玉溪市传统耕作习惯及秋末降水对蚕豆根病发生的影响。结果表明:开沟质量越高,蚕豆根病的发生程度越轻:江川龙街的病田率仅为16.4%,1级指数区比4级指数区病田率平均下降57.7%;实行窄墒深沟,取土碎垡盖墒的开沟方法,有利于形成适宜蚕豆生长发育的土壤水分环境,对预防蚕豆苗期根病有明显的作用;澄江坝子蚕豆根病发生严重,除与开沟质量密切相关外,与澄江坝子蚕豆早播也有很大关系。
With macro - survey methodology, the influences of traditional tillage practices and autumn rainfall in the occurrence of Vicia faba root disease was investigated in the present work. The results revealed that high quality ditching might obvious inhibited the occurrence of Vicia faba root disease. The field disease rate in Jiangchuanlong Street was only 16.4%. Compared with index 4 area, and the field disease rate of index 1 area decreased by 57.7%. Implementation of narrow - entropy ditch was proved to be conducive to Viciafaba growth and and beneficial to root disease prevention. Serious Viciafaba root disease in Chengiiang Bazi was, at least partially ascribed to ditching quality as well as early sowing.
