施用草甘膦最重要的一条就是选定最佳用药时期。草甘膦是内吸传导型除草剂,所以要在杂草生长最旺盛时用药,应以开花前用药为最佳时期。一般禾本科杂草对草甘膦较敏感,能被低剂量的药液杀死,而防除阔叶杂草时则要提高浓度;对一些多年生的根茎繁殖的恶性杂草,则需要更高的浓度,杂草叶龄大、耐药力提高,相应的用药量也要提高。其次,是要讲究环境条件。在24℃~25℃范围
Glyphosate is the most important one is the selection of the best medication period. Glyphosate is a systemic herbicide, so to be the most vigorous weed growth medication should be used before flowering medication for the best period. Gramineous weeds are generally more sensitive to glyphosate, can be killed by low doses of liquid medicine, and control of broadleaf weeds to increase the concentration; for some perennial rhizomatous breeding weeds, you need a higher Concentration, weed leaf age, resistance increased, the corresponding dose should be increased. Second, we must pay attention to environmental conditions. In the range of 24 ℃ ~ 25 ℃
