水稻普通矮缩病在我国南方稻区的浙江、江苏、上海、安徽、江西、福建、湖南、湖北、贵州、云南等省市均有发生。近年来已成为水稻主要病害之一。为了探明其发生规律和防治措施,我们于1970～1973年间先后在黄岩县马铺公社管淋大队、金华县秋滨公社朱基头大队和萧山县迳游公社下俞大队设立研究基点,与当地植保员一起摸索田间发病规律,研究防治措施,并在杭州本院对传毒昆虫的传毒特性等也进行了一些观察研究。现将几年来所得的结果综合整理如下。
Rice common dwarf disease in China’s southern rice in Zhejiang, Jiangsu, Shanghai, Anhui, Jiangxi, Fujian, Hunan, Hubei, Guizhou, Yunnan and other provinces and cities have occurred. In recent years, it has become one of the major diseases of rice. In order to find out its occurrence and prevention and control measures, we set up a research base in 1970 and 1973 successively at Guanlin Brigade of Mapu Commune in Huangyan County, Zhujiadou Brigade of Qiu Bin Commune in Jinhua County and Xia Yu Brigade of Xiayou County Commune Commune The local plant insurer worked together to find out the regularity of disease in the field, studied the prevention and control measures, and conducted some observations on the toxicity characteristics of the poisonous insects in our hospital in Hangzhou. Now the results obtained over the past few years are summarized below.
