草甘磷对植物绿色部分具有很强的杀伤力。植物吸收药液后,可传导到根部,使其腐烂枯萎死亡,是果园理想的除草剂。草甘磷可根除果园一年生和多年生杂草,但对土壤中未萌发的杂草种子和尚未出土的杂草,因未着药而无效。所以,果园用草甘磷除草,必须在杂草充分萌发、长出绿色茎叶时喷药,效果才好。 Glyphosate green plant has a strong lethality. After the plant absorbs the liquid, it can be transmitted to the root to make it decay and wilt, which is the ideal herbicide in the orchard. Glyphosate can eradicate annual or perennial weeds in orchards, but weeds that are not germinated in the soil and weeds that have not been unearthed are not effective because they are not medicated. Therefore, the orchard with glyphosate weeding, germination must be fully weeds, grow green stems and leaves spray, the effect is good.
