麦田化学除草一般在小麦3叶期后(10月下旬左右)和次年返青至拔节前(2月下旬至3月中旬左右)进行。以看麦娘等单子叶杂草为主的麦田,每1/15公顷町用6.9%骠马乳油50～75毫升,对水50千克喷雾,防效可达90%以上。 Wheat field chemical weeding is generally carried out after the third leaf stage of wheat (late October or so) and the rejuvenation of the following year to the pre-jointing stage (from late February to mid-March). In order to see Ophiopogon and other monocotyledonous weed-dominated wheat fields, each 1/15 hectare chooses 6.9% of Emu EC 50-75 ml and 50 kg of water to spray, and the control effect can reach over 90%.
