水稻白叶枯病是我省水稻上主要病害之一,严重威胁水稻生产。从早、中、晚稻被害程度来看,早、晚稻受害轻,损失小,中稻发病面积大,受害重,损失大。 选育抗病品种是减轻白叶枯病为害的经济有效途径。秧田防治是综合防治该病的关键措施。为此,1974～1976年着重开展了水稻品种抗病性鉴定和秧田药剂防治试验,示范工作,现简结如下。 Rice bacterial leaf blight is one of the main diseases on rice in our province, which seriously threatens rice production. From the early, middle and late rice victims of the degree of view, early and late rice victims of light, small losses, medium incidence of large area, heavy damage, loss. Breeding of resistant varieties is an economical and effective way to reduce bacterial blight. Seedling control is the key to comprehensive prevention and treatment of the disease. To this end, from 1974 to 1976 focused on the identification of disease resistance of rice varieties and seedling pesticide control trials, demonstration work, are summarized as follows.
