条纹病是我市二棱大麦的主要病害,一般田块病株率3%左右,重病田块病株率达40%以上,以迟播田受害最重。石灰水浸种是防治病害的有效措施,但夏天浸种时如遇有阴雨,种子得不到及时晾晒,常造成烂种和发芽,影响到这一技术的推广。为了寻求简便易行的浸种措施,1983—1986年我们在浸种技术方面作了一些改进,取得了明显的效果。现报告如下: 一、改夏天浸种为播种前浸种1983—1984年试验,“盐幅矮早三”大麦在播种前用1%石灰水浸种48小时,防病效果较好。以湿籽播种,收获前调查,在对照区病株率13.3—15.7%的情况下,处理 Stripe disease is the main disease of two-rowed barley in our city. Generally, the number of diseased plants in the field is about 3%. The rate of diseased plants is more than 40%. Lime water soaking is an effective measure to prevent and cure diseases. However, in case of rainy soaking in summer soaking seeds, the seeds can not be dried in time, often resulting in rotting and germination, which affects the popularization of this technology. In order to seek simple soaking seed soaking measures, we made some improvements in seed soaking technology from 1983 to 1986 and achieved remarkable results. Now report as follows: First, change the summer soaking for the soaking seeds before sowing 1983-1984 test, “salt breadth three” barley before sowing with 1% lime soaked 48 hours, better disease prevention. Seeding with wet seeds, before harvest investigation, in the control area diseased plants rate of 13.3-15.7% of the case, the treatment
