随着化学工业的发展,为水稻生产不断地提供经济高效的化学除草剂。化学除草已为我省在稻作生产中,实行综合灭草的重要措施之一。除草醚、二甲四氯、扑草净已在大面积上推广应用;杀草安应用面积也正在逐年增加;稗草稀在试点单位已经取得了良好效果。上述几种药剂已经构成了化学除草体系,如能合理搭配、科学施用、则足可以消灭水田中危害性极强的稗草、三棱草(水葱)、荆棱草(地、梨)、眼子菜(水上漂)等恶性杂草,从
As the chemical industry has evolved, it has been providing cost-effective chemical herbicides to rice production. Chemical weeding has been one of the important measures in our province to implement integrated weed control in rice production. Weeding ether, dimethyl tetrachlor, prometryne has been widely applied in large areas; the application area of herbicide is also increasing year by year; barnyard grass dilute in the pilot units have achieved good results. The above several agents have formed a chemical weeding system, if they can be reasonably collocated and applied scientifically, it is enough to eliminate the extremely harmful barnyard grass, the trifoliate grass (water onion), the sable grass (ground, pear) in the paddy field, Ocimum vegetables (water drift) and other malignant weeds, from
