我市单季稻条纹叶枯病在八十年代再度流行,给水稻生产带来很大威胁。1983年全市单季稻发病面积183.65万亩,占单季稻总面积74.9%,大田病株率5.46%,严重田块病株率超过80%。由于对发病规律缺乏足够的认识,防治工作盲目性很大,损失产量达4297.4万斤。因此,我市于当年组成科研协作组,开展病害发生规律及防治技术的试验研究,三年来已取得初步成果。
Single-season rice stripe leaf blight in the city again popular in the eighties, to bring great threat to rice production. In 1983 the city’s single crop area of 183.65 million mu, accounting for 74.9% of the total area of single season rice, field disease rate of 5.46%, severe field disease rate of more than 80%. Due to the lack of adequate understanding of the pathogenesis, prevention and control work is very blind, with a loss of output of 42.974 million kg. Therefore, the city in the year to form a scientific research cooperation group to carry out the law of disease occurrence and prevention and control of experimental research, has achieved initial results over the past three years.
