| Abstract: | The weedicide test of protective cultivation in wheat field fallow of dry farming region in Kongtong district of Pingliang City.The results showed that the control effect of the correction and control effect of fresh weight of 2 250 g/hm2,1 500 g/hm2 of 74.7% Nongjiale water-soluble granules,18 000 mL/hm2,12 000 mL/hm2 of 10% glyphosate aqueous solution in 14 day after pesticide application were 97.5% and 99.0%,respectively,and the persistence of long,can be used for perennial weed control.900 mL/hm2 and 1 800 mL/hm2 of 20% of the herbicide Paraquat processing speed,but persistence is short,easy to perennial weeds in the short term regeneration,it can be used for annual weeds. |
