1991年四川全省计划蓄留再生稻面积700万亩,收割面积为555.2万亩,平均亩产80.1公斤。单产不稳不高是个普遍问题,在影响单产的诸因素中,病虫为害是重要因素之一。除1991年飞虱大暴发有些特殊和部分群众对纹枯病的防治有所认识外,就整个再生稻的病虫防治而言,无论在认识上或是在防治实践上,都还存在一些亟待探索的问题。1.再生稻的病虫防治应与常规栽培有所区别再生稻是利用水稻收割后存留于稻桩上的休眠芽,通过强化管理,促使再次萌发、生
In 1991, Sichuan province planned to reserve 7 million mu of ratoon rice and harvest 5.55 million mu of land, yielding an average of 80.1 kilograms of mu per mu. Unmanaged yield is a common problem. Among the various factors affecting yield, pest damage is one of the important factors. In addition to some special and some masses of planthopper outbreaks in 1991 that know about sheath blight prevention and control, in terms of pest and disease control of the entire ratoon rice, there are still some urgent needs in terms of knowledge or prevention and control practices Exploring the problem. 1.
