一、化学除草 果园化学除草一般使用草甘膦。10％草甘膦水剂使用一周左右杂草开始发黄枯萎,10～15天地上部干枯死亡,一个月左右地下部变褐腐烂,杀草效果100％。使用草甘膦除草要把握以下几个技术关键。 1.喷药质量 喷药时要求喷雾器的喷嘴向下,尽量接近杂草,喷洒均匀周到,防止药雾飘移到果树枝叶上,以免造成药害。尤其杏树对草甘膦敏感,易出现药害,因此,杏园使用草甘 First, the chemical weeding Orchard chemical weeding generally use glyphosate. 10% glyphosate using weeds about a week began to yellow brown withered, 10 to 15 days dead above the ground, a month or so brown rotting the ground below the grass killing effect of 100%. The use of glyphosate herbicides to grasp the following key technologies. 1. Spraying quality Spraying spray nozzle requirements down, as close to weeds, spray evenly and thoughtfully, to prevent drug mist drift to the branches of fruit trees, so as to avoid injury. In particular, apricot tree is sensitive to glyphosate, prone to injury, therefore, apricot garden grass sweet
