【摘要】 ２．８％稻床净经过１９９３～１９９４年全国大田药效网试验表明：该药是一种高效、低毒、广谱、安全性强的旱育秧田较为理想的除草剂。在水稻旱育秧苗床播种复土１厘米后，施用量：东北地区为５０～６０公斤／每公顷；上海地区为４４～４９公斤／公顷，施用时加过筛湿润细土３７５０～４０００公斤，搅拌均匀，用手撒施，之后盖塑料薄膜，保温保湿。可有效地防稗草、龙葵、野黍、狗尾草、藜、雾、苋、草、苣卖菜、鲤肠、节节菜、矮慈菇、异性莎草等多种一年生和多年生杂草。更多还原

【Abstract】 Abstract Two years eaperiment on chemical-effect experiment network arround the country showedthat 2. 8% Daochuangjing is a kind of herbicide with high effect. low toxicity, wide spectrum andmuch more safety to drought rice seedling-bearing bed. After covering with soil on seeds, the herbicidecan be used. Its usage is as follows: (1) In Northeast regions, 50～60kg Daochuangjing Per ha is applied, (2) arround Shanghai, 44-49kg per ha. It shouldbe mentioned here that the herbicide needs tobe mixed with 3750-4000kg seived wet fine. soil and then cast on the seed bed with hands. After that,plastic filmis covered on in order to maintain moisture and increase soil temperature. This kind of herbicide can effectively contral annual and Perennial weeds, Such as: Echinachioa Crusgalli cu, Setariaviridis, Sagitaria pygmaea (Mig), Cyperas difformis(L), Amarathus spinocus(L), Chenopodiumabout (L), Solanum nigrum(U) and on.更多还原
