Abstract
Weeds are important factors that influence the output of upland rice in upland rice field.In order to characterize weeds in upland rice field and select the suitable herbicides,the categories and number of weeds in upland rice field were investigated at different time after sowing and efficacy of herbicides using different herbicides and concentrations were assessed.The results showed that the features of weeds in upland rice field were various varieties,large quantities and rapid germination.Upland-Rice-Herbicide No.1 with 3000-3150mL/ha and Ronstar with 3750mL/ha had good control effects 93.39%.The effects of mixture of two herbicides were not good.Herbicide mixture(Upland-Rice-Herbicide No.1 + Butachlor + Ronstar,Upland-Rice-Herbicide No.1 + Butachlor + MCPA,Upland-Rice-Herbicide No.1 + Ronstar + Goal) had good control effect(95%) and could be adopted in upland rice field.
