据日本《杂草研究》(1975 19)介绍,用敌稗和土壤长效除草剂(如甲氧除草醚、除草醚、地散磷、灭草灵、TOPE、草达灭、Amiprophos和杀草丹)混合使用,进行防除旱地直播水稻田杂草试验。其中以敌稗和杀草丹的混合物最为有效。评选了这两种除草剂的使用剂量。在水稻二叶期时,使用敌稗17.5克/公亩加杀草丹50克/公亩对杂草防效最好,对水稻药害很小。而在高剂量敌稗35克/公亩和杀草丹75克/公亩进行单独处理时则不能达到完全防除杂草 According to the Japanese Weed Research (1975-19), the use of propanil and soil long-acting herbicides such as methicillin, fenpropicol, azadirachtin, mefenpyr, TOPE, Dan) mixed use of dryland to control weeds in direct seeding rice fields. Among them, propanil and herbicide mixture of Dan most effective. The dosage of these two herbicides was chosen. In the second leaf stage of rice, the use of 17.5 grams of propanil and 50 grams of herbicide to kill herbaceous grass per square centimeter of the weed control effect is best, little damage to rice. However, the complete control of weeds could not be achieved when the high-dose propanil 35 g / acre and the herbicide 75 g /
