金华是浙江省的葡萄主产区,全市鲜食葡萄的种植面积达4万亩,早春葡萄园的除草一直来都采用10%草甘膦水剂,但是使用草甘膦后碰到一些具体问题。首先,金华农区早春往往阴雨连绵,若施药后遇上大雨,除草效果就不理想。其次,草甘膦对雀麦、碎米荠、酸模等杂草效果较差。第三,草甘膦对暴露于地表的葡萄根,有内吸伤害作用。此外近年有些农药经营户,为了提高除草效果在大桶包装的草甘膦中加入少量甲黄隆,农民使用这种草甘膦后,葡萄就会停止生产,叶片变黄,严重的田块,葡萄植株会慢慢枯死,所以不少农户化大量劳力进行人工除草也不愿使用草甘膦。针对这一现状,我们于2000年分别在
Jinhua is the main grape producing area in Zhejiang Province. The planting area of fresh grape in the whole city is up to 40,000 mu. The weeding of early spring vineyards has always used 10% glyphosate, but met some specific problems after using glyphosate . First of all, Jinhua rural areas often rainy and rainy in early spring, if after application of heavy rain, weeding is not ideal. Second, glyphosate has less effect on weeds such as broccoli, chestnut rice, and acid mold. Third, glyphosate has a systemic effect on grape roots exposed to the earth’s surface. In addition, some pesticide operators in recent years, in order to improve the weeding effect in the barrel of glyphosate added a small amount of jasmine, farmers use this glyphosate, the grape will stop production, the leaves turn yellow, serious plots, grapes Plant will die slowly, so a lot of labor to do a lot of labor manual weeding do not want to use glyphosate. In response to this situation, we were in 2000 respectively
