使用丰产抗病品种是综合防治稻瘟病经济有效的措施,1971年以来,在蒲江县基点,研究以使用丰产抗病品种为中心的综合防治措施。该县是我省西部的常发病区,由于山林多,日照少,地势阴蔽,空气湿度大,适于病害流行。从1972年开始先后鉴定出了“泸双1011”(1972)、“窄叶青8号”(1973)、“蜀丰105”(1974—1975)、“74—613”(1977)等抗病丰产良种。1973年以后,由于抗病品种的推广,病害逐步得到控制。实践证明使用丰产抗病良种是防病保产的有效措施。
The use of high-yielding disease-resistant varieties is a cost-effective measure for the comprehensive control of blast disease. Since 1971, a comprehensive prevention and control program centered on the use of high yield and disease-resistant varieties has been studied in Pujiang County. The county is the frequent ward in the western part of our province, due to more forests, less sunshine, topography shade, air humidity, suitable for disease epidemic. From 1972 onwards, the disease resistance such as “Lu Double 1011” (1972), “Narrow Yeqing 8” (1973), “Shu Feng 105” (1974-1975), “74-613” (1977) High yield varieties. After 1973, due to the promotion of disease-resistant varieties, the disease was gradually controlled. Practice has proved that the use of high yield disease-resistant varieties is an effective preventive measures.
