近年来,各种作物田草害损失有所增加,一般田块在10%-20%,严重的高达50%以上,因此,加强冬种作物化学除草尤为重要。现根据油菜田、麦田的草相特点及各地试验示范结果,就不同冬种作物化学除草技术介绍如下:一、大小麦田1.免耕田播种前除草。在水稻收割后,麦子播种前3-5天,亩用10%草甘膦水剂400-600毫升,兑水30升均匀喷雾,以消灭老草。2.播后苗期除草。在播后至麦苗2叶1心期或杂草2叶1心期前,亩用50%异丙隆(江苏宝带农药厂生产)
In recent years, grassland damage losses have increased in a variety of crop fields, with fields ranging from 10% to 20% and severeness up to 50%. Therefore, it is particularly important to strengthen chemical weeding in winter crops. Now according to rapeseed, wheat grass characteristics and around the demonstration test results, different varieties of winter crop chemical weeding technology are as follows: First, the size of the wheat field 1. No-tillage before sowing weeding. 3-5 days before sowing the wheat, 400-600 ml of mu with 10% glyphosate and 30 liters of water are evenly sprayed to eliminate the old grass after the rice is harvested. 2 seedling weeding after sowing. After sowing to wheat 2 leaf 1 heart or weed 2 leaf 1 heart period, mu 50% isoproturon (Jiangsu Baobain Pesticide Factory production)
