Screening of herbicides at seedling stage of Atractylodes chinensis
In the process of artificial planting and management,weeds affect the growth and development of Atractylodes chinensis seedling.In order to find a safe,efficient and broad-spectrum herbicide for Atractylodes chinensis seedlings.Three kinds of herbicides,108 g/L haloxyfop-R-methyl EC,250 g/L fomesafen and 10%tribenuron-methyl,were used to spray the main weeds(Ixeris chinensis,Setaria viridis and Portulaca oleracea)and Atractylodes chinensis seedlings in the field.The suitable herbicide concentration and suitable ratio were selected,and the control effects of weeds and Atractylodes chinensis seedlings under different treatment ratios were counted.The results showed that 108 g/L haloxyfop-R-methyl EC had good control effect on Setaria viridis.250 g/L fomesafen had effective control effect on three weeds,but had damage to Atractylodes chinensis.10%tribenuron-methyl had good control effect on Ixeris chinensis.0.023 mL/m2 108 g/L haloxyfop-R-methyl EC+0.024 mL/m2 250 g/L fomesafen had the least damage to Atractylodes chinensis and the best effect on weed control.The herbicides selected in this study can provide theoretical guidance and reference value for the field cultivation of Atractylodes chinensis.
