近日接到许多农民来信和来电,咨询农药对下茬作物的影响等问题。为了更好地解答农民心中的疑惑,笔者咨询了植保站的有关专家。据了解当前对后茬作物造成药害的长残留除草剂品种主要有豆磺隆、莠去津、快杀稗、甲磺隆等,不同品种的长残留除草剂对后茬作物的影响还因施用浓度的不同而不同,浓度越高,在土壤中的存留的时间就越长。所以农民在决定今年种啥时一定要考虑上茬作物使用了什么除草剂,以免产生药害造成损失。
Recently, many peasants have received letters and phone calls asking about the impact of pesticides on the crop. In order to better answer the doubts of farmers in mind, I consulted plant protection station experts. It is understood that the current crop residues caused by pesticide residues of long-legged herbicide varieties are mainly metsulfuron-methyl, atrazine, barnyardgrass, metsulfuron, etc., the long-residue herbicides of different varieties on the succession of crops also because of The application concentration varies, the higher the concentration, the longer the residence time in the soil. Therefore, when farmers decide to plant their crops this year, they must consider what herbicides were used on the crops in order to avoid any damage caused by injury.
