摘要:

采用机插秧“插喷同步”技术,于2019年开展大田试验,分别施用4种除草剂(33%嗪吡嘧磺隆、19%氟酮磺草胺、25%双环磺草酮、300 g/L丙草胺+10%苄嘧磺隆)进行除草,对比各除草剂处理对水稻的安全性及对稻田杂草的防治效果。结果表明,药后水稻均未发生可见药害,参试除草剂安全性好;药后35 d供试除草剂对试验田总草防效达95.0%以上;与施用除草剂处理相比,未施药对照水稻产量损失严重,减幅12.5%~42.7%。可见,“插喷同步”技术是一种高效除草技术,供试4种除草剂均能有效防治杂草,降低除草成本,提高种稻效益。

Abstract:

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.
