Abstract: 【Objective】To solve the harm caused by sunflower broomrape to host plants in the northern foot of Yinshan Mountain,and provide new ideas and methods for comprehensive prevention and control of sunflower broomrape.【Methods】The experiments were carried out in the sunflower planting area of the northern foot of Yinshan Mountain. Microecological agents were applied to the prevention and control of sunflower broomrape by different application methods,drip irrigation at different growth stages,and different application doses. The plant height,stem diameter,flower disk diameter,and yield of sunflowers were investigated,and the parasitic rate,parasitic intensity,parasitic degree,height,withering rate,and fresh weight of different treatments of sunflower broomrape were analyzed.【Results】Compared with the control group with clear water(D1),the yield of sunflower was increased by 83.6% on average,the parasitic rate of sunflower broomrape was decreased by 10.3% on average,the wilting rate of sunflower broomrape was increased by 24.8% on average,the height of sunflower broomrape was decreased by 23.9% on average with basal application 150 kg/hm2 microecological agents before sowing. Compared with the clear water control(Y1),the yield of sunflower increased by 21.4% on average,the parasitic rate of sunflower broomrape decreased by 54.3% on average,the wilting rate of sunflower broomrape increased by 43.3% on average,the fresh weight of sunflower broomrape decreased by 533.0 kg/hm2 on average with drip irrigation 112.5 L/hm2 microecological agents at 4-6 leaf stage.【Conclusion】In the process of sunflower planting in the northern foot of Yinshan Mountain,appropriate amount basal application prevention and control sunflower broomrape microecological agents before sowing can significantly reduce the parasitic rate and growth height of broomrape,increase its wilting rate,and significantly increase the yield of sunflower. In addition,in the 4-6 leaf stage of sunflower,the application of microecological agents by drip irrigation also has the effect of effectively preventing and controlling sunflower broomrape disease and improving sunflower yield and quality.
