油菜菌核病是我县油菜生产上的重要病害。历年平均株发病率达24%,少数白菜型土油菜损失率高达50%以上。1978—1979年,我们对此病进行了观测调查,认为此病的防治,主要应抓好以下几点:一、选用高产抗病品种。油菜有甘蓝型,白菜型两种。白菜型油菜虽然早熟,但抗病力差,产量较低。甘蓝型油菜,植株高大,分枝多,结荚多,千粒重高,抗病力较强,耐寒性较好,产量高而稳定、增产潜力大。近三年来我县基本上以种植甘蓝型油菜为主,以九二、早丰1号、川油9号等栽培较多。甘蓝型油菜品种间
Sclerotinia sclerotiorum production is an important disease in our county. The average annual incidence of strains over the years up to 24%, a small number of cabbage-type rape loss rate as high as 50%. From 1978 to 1979, we conducted an observation survey of the disease, that the prevention and treatment of the disease, mainly should do a good job the following points: First, the selection of high yield disease-resistant varieties. Rape has a cabbage type, cabbage type two. Brassica napus although precocious, but poor disease resistance, lower yield. Brassica napus, tall plants, more branches, more pods, 1000-weight, strong resistance to disease, cold tolerance is good, high yield and stability, yield potential. In the past three years, our county has basically planted Brassica napus mainly to 92, early Feng 1, Sichuan oil 9 and other cultivation more. Brassica napus varieties
