保试达防除水稻田杂草稻研究

目的]明确保试达防除稻田杂草稻的效果及安全性，为稻田杂草稻防除提供高效、安全的解决方案。方法]开展以保试达为基础药剂对杂草稻防除效果的研究，通过选择常年杂草稻发生严重的中产稻田为试验地和保试达单用、与农思它混用等方法进行试验。结果]保试达和农思它对杂草稻和直播稻田的主要杂草都有较好的防治效果。硝酸钾、保试达和农思它配套使用处理对产量有最终安全性。结论]研究结果为水稻生产提供了参考。

Study on Glufosinate-amonium in Controlling Oryza sativa f. spontanea in Rice Field

Objective The aim was to explore the efficacy and safety of glu-fosinate-ammonium in controlling Oryza sativa f. spontanea in rice field, for pro-viding efficient and safe solution for controlling Oryza sativa f. spontanea. Method] The research which taking the glufosinate-ammonium as the based phar-maceutical for controlling Oryza sativa f.spontanea was carried out, by se-lecting the middle paddy in which Oryza sativa f. spontanea serious outbroke at perennial as the testing ground, and single-use of glufosinate-ammonium and mix of glufosinate-ammonium and oxadi-azon. Result] The results showed that glufosinate-ammonium and oxadia-zon had better effects for controlling O-ryza sativa f.spontanea and the main weeds in seeded rice. Supporting use treatment with potassium nitrate, glufosinate-am-monium and oxadiazon had final safety of yield. Conclusion] The results provid-ed a reference for the rice production.
