Study On The Mixed Effect Of Herbicides In Soil Treatment Of Miscellaneous Bean Fields

Soil treatment has the characteristics of soil treatment of safety,high efficiency and simple.Herbicide is seldom used in mixed beans fields for soil treatment,in order to achieve the safety and control technology of the mixed beans field.Adopt the methods of field experiment,through the soil treatment to screen the safe and efficient screening mixed beans herbicide,the research of its safety,weed control effect on mixed beans,agronomic characters,yield,etc,the influence of the results are as follows: 1.Adzuki bean soil treatment12% oxadiazon 3000 m L/hm2;25% romesafen 1875 ~ 2250 m L/hm2 + 48% colmazone 1125 ~ 1500 m L/hm2;25% romesafen 1500 ~ 1875 m L/hm2 + 12% oxadiazon 3000 m L/hm2 evil grass,can improve the germination rate.25% romesafen 1875 m L/hm2 + 12% oxadiazon 3750 m L/hm2,strain effect control efficiency was 96.9%,fresh control efficiency is 87.0%,dry control efficiency was 88.0%,increase 5.31%.25% romesafen 1500 m L/hm2 + 12% oxadiazon 4500 m L/hm2,strain control effect was good,increase tje production effect 1.10%.2.Mung bean soil treatment25% romesafen 1500 m L/hm2 + 48% colmazone 1125 m L/hm2 emergence rate to compare basic same,strain effect control efficiency was 92.4%,fresh control efficiency was 94.5%,dry control efficiency was 94.4%,to increase the production effect 7.11%.3.Kidney bean soil treatment33% pendimethalin 3750 ~ 4500 m L/hm2 + 50% prometryn 1500 ~ 3000 g/hm2 high safety of kidney bean.33% Pendimethalin 4500 m L/hm2 + 50% prometryn 2250 g/hm2,strain effect control efficiency was 96.9%,fresh control efficiency is 93.6%,dry control efficiency was 93.2%,to increase production effect 23.51%.Adzuki bean soil with 25% romesafen 1500 ~ 1875 m L/hm2 + 12% oxadiazon 3750 ~ 4500 m L/hm of Adzuki bean has important effect on the red bean safety,control of weeding,yield increase;Mung bean soil with 25% romesafen 1500 m L/hm2 + 48% colmazone 1125 m L/hm2 has important effect on the mung bean safety,control of weeding,yield increase.Kidney bean soil with 33% pendimethalin 3750 ~ 4500 m L/hm2 + 50% prometryn 1500 ~ 3000 g/hm2 of kidney bean has the safety,weed control effect is better,increasing yield.
