摘　　要：以食用向日葵9023为试验材料,用48%仲丁灵、48%氟乐灵、72%金都尔3种药剂,设置低、中、高3种不同浓度播前处理土壤,调查分析不同药剂处理对列当寄生向日葵危害程度的影响。结果表明:3种药剂不同浓度处理对向日葵列当严重度和产量的提高均具有较好的效果,其中,72%的金都尔中浓度处理对向日葵列当的严重度控制在15.93,粒长、粒宽、百粒重、出仁率等均显著高于对照,产量最高,达4248kg/hm^2,较CK的产量显著提高,提高率为45.0%,列当控制效果好。3种药剂随着用药浓度的增加,对向日葵籽粒的粒长、粒宽和百粒重等均有所减小,说明药剂用量越高对向日葵生长和产量具有抑制效应,且环境污染也加重。综合分析,72%的金都尔中浓度处理防控列当较为理想。In this experiment,the edible sunflower 9023 was used as material.The soil was treated with 48%butralin,48%trifluralin and 72%Dual Gold,and the soil was treated with three different concentrations.Parasitic sunflower damage degree.The results showed that the three kinds of chemicals had better effects on the improvement of the se⁃verity and yield of sunflower,among them,medium concentration treatment of 72%Dual Gold was controlled the se⁃verity of sunflower broomrape in 15.93,and the grain length,grain width,100 grain weight and kernel rate were sig⁃nificantly higher than those of the control,the yield was the highest,up to 4248kg/hm^2,significantly higher than that of CK,with an increase rate of 45.0%,The effect of rank control is good.With the increase of the three chemicals concentration,the grain length,width and 100 grain weight of sunflower decreased,which indicated that the higher the dosage of three chemicals,the more restrained the growth and yield of sunflower,and the more serious the envi⁃ronmental pollution.Comprehensive analysis drawn,the medium concentration of 72%Dual Gold is an ideal treat⁃ment for the prevention and the control of Orobanche cumana.
