In this paper the field experimentation was conducted during in 2012 in Huida Farm,Huizhou County,Guangdong Province.The main treatment is herbicide（Pretilachlor ＋ Bensulfuron-methyl,Yangguo and Butachlor）,the sub-treatment is application method（soil treatments,seedling treatment and integrated treatment）.Results of investigation showed that under the soil moist conditions two methods can significantly controlled weed when were applied at 1 or 2 days after the seeding.one which 80 g of 36% Pretilachlor＋4% Bensulfuron-methyl deluted to 50 kg of water was sprayed on the leaves of the weed per 667 m^2;another which 200 g of 23.9% Butachlor ＋1.1% Bensulfuron-methyl mixed with 15 kg of sandy soil were applied on the pad per 667 m^2.
