随着化学工业的发展和引进困外新技术,为水稻生产不断地提供经济高效的化学除草剂。从六十年初期以来,除草醚、二甲四氯,扑草净已在大面积上推广应用,杀草丹应用面积也正在逐年增加,已成为稻作生产中实行综合灭草的重要措施之一。今年又从国外进口一批新除草剂,即禾大壮和灭草特(去草胺),这两种除草剂很多地方都是首次使用,所以许多地方对使用方法不太熟练或者持有不同看法。为了推广新技术,伊用好这两种新除草剂,我们主要根据试验结果和参考国内外使用经验,对灭草特和禾大壮除草剂的灭草技术,谈谈看法和体会供各地参考。
With the development of the chemical industry and the introduction of new technology that is beyond its control, it will continue to provide cost-effective chemical herbicides for rice production. Since the early 1960s, weeding ether, MCPA and prometryn have been widely applied in large area. The area of applying herbicide Dancandi is also increasing year by year, which has become an important measure to implement integrated weed control in rice production one. This year they imported a number of new herbicides from abroad, namely, Herbaceous and Herbicide (tolachlor), both of which are used for the first time in many places, so many places are not familiar with or use different methods of treatment view. In order to promote new technologies, Yi used these two new herbicides well. Based on the test results and reference to domestic and international experiences, we talked about the views and experiences for the reference of weed control technologies. .
