为明确70%三氯吡氧乙酸.草甘膦可溶性粉剂在免耕小麦田的应用前景,建立小麦田杂草管理体系,研究了三氯吡氧乙酸.草甘膦对小麦田杂草的防除效果,并测定了田间透光率、杂草对养分和水分的吸收量和小麦产量。结果表明,三氯吡氧乙酸.草甘膦对免耕小麦田主要杂草菵草、小飞蓬、牛繁缕、野老鹳草等均有较好的防除效果。并显著提高了小麦田间的透光率,降低了杂草对田间养分和水分的吸收,促进了光合作用,小麦增产效果显著。
In order to clarify the application prospects of glyphosate-soluble 70% triclopyr and soluble glyphosate in tillage-free wheat field, weed management system was established in wheat field to study the effects of triclopyr and glyphosate on weeds in wheat field Effect, and field transmittance, weed nutrient and water absorption and wheat yield. The results showed that triclopyr and glyphosate had a good control effect on the main weeds in the no-tillage wheatgrass, Scirpus monnieri, Bovine splendens and Geranium spp. And significantly increased the light transmittance of wheat in the field, reduced weeds absorption of nutrients and moisture in the field, promoted photosynthesis, and the wheat yield was significantly improved.
