1973—1990年的实地调查和标样鉴定结合有关报道明确,我国水稻条纹叶枯病分布于福建、江西、浙江、上海、江苏、安徽、湖北、广西、广东、云南、山东、河南、河北、北京、辽宁和台湾等16个省区,其中在福建已波及36个县市.以四优2号和黎明粳为供试品种,采用同期播种、分期接种方法,明确了水稻三叶期、五叶期和分蘖始期接种发病的损失可达79%-100%;分蘖盛期接种发病的,减产50%-70%;幼穗分化期40%-50%;孕穗期10%-15%;齐穗期1-3%;乳熟期不受影响.2个品种趋势一致,以黎明粳受害大些.这一结果打破了以往把幼穗分化期以前作为病害感染的界线,并可为病害测报和治虫防病提供科学依据.
Field surveys and standard samples from 1973 to 1990 confirmed that the reports of rice stripe disease were distributed in Fujian, Jiangxi, Zhejiang, Shanghai, Jiangsu, Anhui, Hubei, Guangxi, Guangdong, Yunnan, Shandong, Henan, Beijing, Liaoning and Taiwan, including 36 counties and cities in Fujian Province.With Siyou 2 and Dawmingjing as the tested varieties, the methods of sowing and staging inoculation in the same period were used, The incidence of leaf stage and tillering inoculation onset up to 79% -100%; incidence of tillering inoculation disease, cut 50% -70%; young panicle 40% -50%; booting 10% -15%; Qi 1-3% in the panicle, and no effect in the milk-ripening stage.The trend of the two cultivars was the same and the damage to dawn japonica was larger, which broke the boundary of the disease infection before the young panicle differentiation period and could report the disease And pest control provide scientific basis.
