本刊讯众所周知,草甘膦属于内吸传导型灭生性除草剂,药液通过杂草的茎和叶渗透、吸收、传导到杂草全身,干扰蛋白质的合成,导致杂草中毒发黄,最终引起根、茎、叶干枯死亡。而引起杂草中毒发黄的时间与温度、用药浓度、草相等因素有关,以一年生敏感性禾本科杂草为例,在高温条件下,中毒时间一般在2~3天,而低温条件下(日均温15℃以下),中毒时间一般在5~7天,在这个过程中,草甘膦药液在杂草体内被充分吸收传导,从而保证了除草的彻底性。
As we all know, glyphosate belongs to the absorption-type exudative herbicides, chemicals through the stems and leaves of weeds infiltration, absorption, conduction to the weeds, interfering with the synthesis of proteins, leading to weed poisoning yellow, eventually Cause root, stem, leaf dry death. Caused by the yellowing time of weed poisoning and temperature, drug concentration, grass and other factors related to the annual grass-sensitive weeds, for example, at high temperatures, the poisoning time is generally 2 to 3 days, while the low temperature conditions Average daily temperature below 15 ℃), poisoning time is generally 5 to 7 days, in the process, glyphosate liquid in the weed body is fully absorbed conduction, thus ensuring the thoroughness of weeding.
