除草剂与植调剂协同使用对小麦增产效果初探

Effect of Synergetic Application of Herbicides and Plant Regulators on Wheat Yield

通过协同使用3%甲基二磺隆可分散油悬浮剂和70%氟唑磺隆水分散粒剂除草剂,同时喷施两次0.5%噻苯隆可溶性液剂,结果表明,对小麦田杂草有良好防除效果,30 d综合植株防效达88.10%,校正后防效为86.45%;施药后促进了小麦产量形成,增产率可达14.84%。

By using 3%metsulfuron methyl dispersible oil SC and 70%fluzosulfuron water dispersible granule herbicide,and spraying 0.5%thiazoluron soluble liquid agent twice,the results showed that it had good control effect on weeds in wheat field.The comprehensive control effect of 30 days was 88.10%,and the control effect was 86.45%.After application,the yield formation of wheat was promoted,and the yield increase rate reached 14.84%.
