稻瘟病、稻白叶枯病和稻褐飞虱是水稻生产上重要的病虫害。生产实践证明,利用水稻本身的抗病虫性,免于或减少化学防治次数,减轻水稻病虫危害,确保水稻高产稳产,是协调防治病虫害的主要手段。为此,我们对参加本市区试的水稻品种进行了抗病虫性鉴定,现将结果初报如下,供生产部门参考。 一、材料和方法 进行抗病虫鉴定品种的种子由上海市种子公司
Rice blast, rice leaf blight and rice brown planthopper are important pests and diseases in rice production. Production practice has proved that the main means of coordinating the prevention and control of pests and diseases is to utilize the pest resistance of rice itself, to prevent or reduce the number of chemical control, to reduce the pest and disease hazards of rice and to ensure the high and stable yield of rice. To this end, we have participated in the city of rice varieties tested for resistance to pest and disease identification, the results are as follows, for the production department for reference. First, the materials and methods for identification of anti-pest varieties of seeds by the Shanghai seed company
