近几年,我县水稻条纹叶枯病频发,通过研究确认,推迟水稻播种期能有效抑制条纹叶枯病的严重发生,所以水稻直播技术得到迅速推广,种植面积逐步扩大,但直播稻田草害是制约直播稻发展和夺取高产的障碍,合理选择除草剂、研究施药方法及适期用药就成为解决直播稻田草害的关键。2008年笔者对江苏快达农化股份有限公司生产的35%苄.丙草WP进行了直播稻田田间除草试验,取得了较为理想的效
In recent years, the frequent occurrence of rice stripe blight in our county confirmed through research that postponing rice sowing period can effectively inhibit the occurrence of stripe leaf blight. Therefore, direct broadcasting technology of rice has been rapidly popularized and its acreage has been gradually expanded. However, Harm is the obstacle to the development of direct-seeding rice and to seize high yield. The reasonable choice of herbicides, the study of application methods and the proper medication have become the key to solve the direct-seeded rice fields. In 2008, the author conducted a field experiment of weeding on direct-seeded rice field with 35% Benzylpropion WP produced by Jiangsu Express Chemical Co., Ltd., and achieved satisfactory results
