稻田稗草和其它一年生杂草,在我省普遍发生危害,特别是秧田造成损失更大。随着化学药剂除草的群众运动的深入发展,各地对于秧田和本田防除稗、杂草,筛选新除草剂的工作,提出了要求。我省早、中稻秧田的播种期,常遇寒流侵袭,温度骤降,造成烂秧。施用除草醚对芽谷和幼嫩秧苗有一定抑制作用,如施用和管理不当,往往加重烂秧的发生。今年我们对秧田使用除草醚的安全应用技术和新除草剂的筛选工作,进行了试验,现将试验结果初报如下: Barnyardgrass and other annual weeds in paddy fields are generally harmful in our province, especially in seedling fields. With the deepening development of the mass movement of chemical weeding, various localities put forward requirements for the control of barnyard grass, weeds and screening of new herbicides in seedling fields and Honda. In our province, the sowing date of early rice seedling and middle rice seedling is often affected by the cold current and the temperature plunges, resulting in rotten seedling. Application of weed-ether on buds and young seedlings have some inhibitory effect, such as the application and management of improper, often increase the incidence of rotting seedlings. This year, we used seedlings of weeding herbicide safety technology and screening of new herbicides were tested, the test results are as follows:
