夏玉米青枯病是一种较为复杂的土传病害,以往发病较轻,近两年有暴发流行的趋势。1995年邯郸市播种夏玉米207466.7hm~2,有57466.7hm~2严重发生青枯病。占播种面积的27.7％。由于青枯病的发生使正在灌浆乳熟的植株,突然青枯死亡,故而对产量影响很大。据田间测产:收获前半月发病的千粒重下降146.1g,收获前10天发病的千粒重降低69.9g。
Summer corn bacterial wilt is a more complex soil-borne diseases, the incidence of mild in the past, the outbreak in the past two years the trend. In 1995, Handan City, sowing summer corn 207466.7hm ~ 2, 57466.7hm ~ 2 serious bacterial wilt. Accounting for 27.7% of sown area. Because of the occurrence of bacterial wilt, the milk-ripening plants are being grouted and the sudden death of the withering and withering plants leads to a great impact on the yield. According to the field test: the first half of the harvest of grain weight decreased by 146.1g, 10 days before harvest incidence of grain weight decreased 69.9g.
