稻瘟病是水稻的主要病害之一,尤其穗颈稻瘟(包括枝梗瘟和粒瘟)为害更大。为了防止这种病害,我们重点改进了氮肥施用技术,使大面积水稻生产实现了丰年无病高产、灾年少病稳产;并在小面积上创造了一批高额丰产的典型。如我场38000多亩水稻,1979年亩产超过千斤,其中有49.23亩亩产1300斤以上。1980年北方稻瘟大流行,我场产量却比1979年又有增长,并有8.64亩亩产达1300斤以上,1.6亩亩产1437.5斤。 Rice blast is one of the main diseases of rice, especially panicle rice blast (including branch and plague and grain blast) harder. In order to prevent this kind of disease, we have focused on improving the application of nitrogenous fertilizers, enabling large-area rice production to achieve disease-free and high-yield during the harvest season and less serious diseases and diseases in disaster-prone areas; and creating a number of typical high-yielding crops on a small area. If my field more than 38,000 mu of rice, in 1979 more than a kilogram per mu, of which 49.23 mu per mu yield of more than 1300 pounds. In 1980, the northern rice blast hit the northern part of the country. However, the output of our field has increased more than that of 1979. There are 8.64 mu of mu produce of more than 1300 kg and the output of 1.6 mu of mu produce is 1,437.5 kg.
