蔬菜生长期短,茎叶容易吸收农药,有的采摘后直接生吃,如农药施用不当,很容易发生中毒现象.为此,蔬菜喷药须注意:1.禁用高毒高残农药.如一六○五、氧化乐果、磷化锌、呋喃丹、六六六等.2.用药适量.如:80%敌敌畏乳剂,每亩最多用4两,90%的敌百虫结晶体,亩最多用2两;40%乐果乳剂,亩最多用2～3两. Vegetable growth period is short, easy to absorb pesticides stems and leaves, and some directly eaten raw after picking, such as improper application of pesticides, it is prone to poisoning phenomenon.To this end, the spraying of vegetables should pay attention to: 1. To disable highly toxic and highly pesticide residues, such as a 650, omethoate, zinc phosphide, carbofuran, BHC, etc. 2. The amount of medication, such as: 80% dichlorvos emulsion, with a maximum of two two, 90% trichlorfon crystals per acre, up to 2 two; 40% dimethoate, mu up to 2 to 3 two.
