杨永杰, 唐伟, 朱晓群, 金文涌, 于晓玥, 张建萍, 陆永良 . 水稻机插秧“插喷同步”封闭除草技术及配套除草剂防效对比[J]. 中国稻米, 2022 , 28(1) : 109 -113 . DOI: 10.3969/j.issn.1006-8082.2022.01.022
A field trial was carried out in 2019, the transplant spray synchronous technology （TSST） and four herbicides （33% metazosulfuron, 19% triafamone, 25% benzobicylon, 300 g/L pretilachlor+10% bensulfuron-methyl） were applied for weed control, the safety of each herbicide treatment on rice and the control effects of weeds in paddy fields were compared. The results showed that, there was no visible phytotoxicity occurred in the rice after spraying herbicide, and the tested herbicides are safe for rice. 35 days after the application of the herbicide, the control effects of the tested herbicide on the total weeds in the test field reached more than 95.0%. Compared with the herbicide treatment, the rice yield loss of the untreated control was severe, with a decrease of 12.5%~42.7%. It can be seen that the TSST is an economical and efficient weeding technology. The four herbicides tested can effectively control weeds, reduce the cost of weeding, and improve the economic efficiency in rice planting.
