摘要
水稻病毒病是系统侵染性病害,是水稻上危害损失重而难以防治的严重病害。概述了广东省化州市水稻上发生的水稻瘤矮病、水稻橙叶病和南方水稻黑条矮缩病3种病毒病的发生概况、发病症状、传播方式,同时针对水稻病毒病发生流行特点,结合病害调查情况对该病毒病在化州地区间歇性暴发流行的原因进行了分析,并预测了未来几年的水稻病毒病发生流行的可能性,提出了加强监测预警预报,选用抗耐病品种,适当推延水稻播栽期,清除田间杂草,防虫网覆盖育秧,药剂拌种与适时对介体昆虫进行化学防治等的"抗、避、断、治"综合防控对策。
Rice virus diseases are systemic and infectious,causing heavy damage to rice,which are difficult to control.This article summarized the occurrence profile,the symptoms and the transmission modes of three types of viral diseases,including rice tumor dwarf disease,rice orange leaf disease and rice black streaked dwarf disease occurring in Huazhou rice fields.At the same time,according to the epidemic characteristics of rice virus diseases,combined with the investigation of the diseases,the causes of the intermittent outbreak of the virus diseases in Huazhou were analyzed,and the possibility of the rice virus disease epidemic in the next few years was also predicted.Prevention and control countermeasures like monitoring,early warning and forecasts,selecting disease-resistant varieties,appropriately delaying the planting period of rice,removing field weeds,covering seedlings with insect nets,dressing with chemicals and timely chemical control of mediator insects,etc.were suggested.
