近年来,随着农业种植结构的调整,河南省大面积推广种植双低杂交油菜,大部分双低杂交油菜品种,对菌核病的抗性较差,属高感病品种。油菜菌核病俗称白秆、烂秆病,河南省上蔡县油菜花期雨水偏多,菌核病常年发生并流行,造成油菜产量大幅度的减产,轻者5%～10%,重者达70%,有的甚至绝收。因此,防治好油菜菌核病是夺取油菜丰产的关键。本文进行了防治油菜菌核病的试验。
In recent years, with the adjustment of agricultural planting structure, large-scale popularization and cultivation of double low rapeseed in Henan Province, most double-low hybrid rapeseed varieties have poor resistance to sclerotinia and are highly susceptible varieties. Rape sclerotiorum commonly known as white stalk, stalk disease, rain in Shangcai County, Henan Province, the flowering period is too much, sclerotinia perennial occurred and prevalence, resulting in a substantial reduction in rapeseed production, light 5% to 10% 70%, and some even never received. Therefore, the prevention and control of rape Sclerotinia is the key to seize rapeseed yield. In this paper, the control rape sclerotinia test.
