摘　　要：为筛选出能应用于谷子生产使用的除草剂,我们分别对四种除草剂混合后各按照1倍,1.5倍和2倍浓度进行喷施。试验结果表明谷草青和拿捕净混合处理的药害最高,二甲四氯钠拿捕净处理和2-4D拿捕净药害最低,且药害随浓度提升而明显提高。综合各项数据,可以得出施用1倍剂量2-4D拿捕净处理、1.5倍剂量2-4D拿捕净处理和1倍、1.5倍二甲四氯钠拿捕净处理对作物的各项影响最小,对田间杂草也可以进行有效控制。In order to screen out herbicides that can be used in millet production,The mixture of four herbicides was sprayed at concentrations of 1,1.5 and 2 times,respectively.The results showed that the combined treatment of Gucaoqing and Sethoxydim had the highest toxicity,and the combined treatment of 2-4D Sethoxydim and MCPA-Na Sethoxydim had the lowest toxicity,and the toxicity increased obviously with the increase of concentration.1 times of 2-4D Sethoxydim,1.5 times of dose 2-4D Sethoxydim and 1 and 1.5 times of MCPA-Na Sethoxydim were the least effect on the crops,and it could also be effectively controlled in the field.
