近几年水稻轻型栽培在我省已大面积推广,但杂草问题尚未得到很好解决,是制约其进一步发展的一大障碍。为探索轻型农业稻田一次性化学除草的可能性,1996年我们在台州市轻栽稻田化除研究课题协作组的统一布置下,在早稻抛秧田中采用35％丁苄可湿性粉剂(乐清乐吉化工厂),50％二氯喹啉酸可湿性粉剂即杀稗王(江苏新沂农药厂),10％苄黄隆超微可湿性粉剂(乐清乐吉化工厂)等药剂,进行了除草药效试验。试验共设四个处理:①丁苄120克;②丁苄150克;③杀稗王30克+苄黄隆15克;④不施药为对照,小区
In recent years, light cultivation of rice has been widely promoted in our province, but the problem of weeds has not yet been solved well, which is a major obstacle to further development of rice. In order to explore the possibility of a one-time chemical weed-control in light-crop paddy fields, we used 35% dibutyltin wettable powder (Yueqing Lok Kyrgyzstan) in the early rice paddy field under the unified arrangement of the research group on light- Chemical plants), 50% quinclorac wettable powder that kill the king of propolis (Jiangsu Xinyi Pesticide Factory), 10% benzyl Huanglong ultra-micro WP (Yueqing Lucky Chemical Factory) and other agents, conducted a herbicidal efficacy test. The test consists of four treatments: ① 120 grams of dibenzyl; ② 150 grams of n-butyl; ③ kill 30 grams of barnyard grass + benzyl Huanglong 15 grams; ④ not spraying as a control, district
