水稻黄矮病是我省水稻上的一种重要病毒病,其为害在一些地区甚至超过稻瘟病,发病田块一般损失3—5成,重者绝收。为有效地控制此病,搞好预测预报是当前生产上急需解決的问题。 此病为虫传病害,主要感染期在秧苗期和本田初期,虽有再侵染,但不重要,加上一般都在晚季暴发成灾,短期预测意义不大,因此,我们把研究重点放在中长期预测上,既可为除虫防病指出关键时间,更能为综合防治提出可行的措施。几年来我们配合有关部门,通过各种途径进行测报,取得了较好的效果。例如闽西北的水稻黄矮
Rice yellow dwarf disease is an important virus on rice in our province, and its damage in some areas and even more than rice blast, the general loss of 3-5% of the field plots, the worst of all income. In order to effectively control this disease, improving forecasting and forecasting is an urgent problem to be solved in current production. The disease is an insect-borne disease, the main infection in the seedling and early Honda, although re-infection, but not important, coupled with the outbreaks are generally affected in the late season, short-term forecast is of little significance, therefore, we focus the study On the medium and long term forecasts, both for pest control and disease prevention pointed out that the key time, but also for comprehensive prevention and control put forward feasible measures. Over the past few years we cooperate with relevant departments, through various channels to measure, and achieved good results. For example, Northwest Fujian rice yellow dwarf
