不同浓度2钾4氯除草剂与肥料配施在稻茬麦田施用的安全性报告

Safety Report on the Application of Different Concentrations of 2 Potassium 4 Chlorine Herbicide and Fertilizer in Rice Wheat Field

试验采用完全随机的方法,将不同浓度除草剂与肥料配施,对其药效及安全性进行试验,并测定不同浓度的除草剂与肥料配施下对小麦的叶面积、株高等形态指标的影响以及对小麦田杂草的防除效果,结果表明:除草剂(2钾4氯)在1 500~2 250 ml/hm^2与肥料配施对小麦生长发育影响较小,安全性高,而且麦田杂草防除效果较好,可作为麦田良好的除草剂施用方法。

This test uses completely random method, different concentrations of herbicide and fertilizer, on their efficacy and safety tests were conducted and determination of different concentrations of herbicide and fertilizer application on wheat leaf area, plant higher morphological index of effect and on weeds in wheat field of anti removing effect. The re- sults show that： （2 potassium chloride） herbicides in 1 500 ml-2 250 ml/h square meters of fertilizer application on wheat growth and development has little effect, high safety and chemical control of weeds in wheat field effect is better, and it can as a good crop of herbicide application methods.
