产生药害后要针对原因采取相应的补救措施。常用药害的急救措施有以下几种:1 喷大量清水或微带碱性的水淋洗。药害发现较早,可以迅速用大量清水反复喷洒受害植物叶面,尽量把植株表面的药物洗刷掉,并增施磷钾肥,中耕松土,促进根系发育,以增强作物恢复能力。同时,由于用大量清水淋洗,能使作物吸收较多水分,增加作物细胞含水量,对作物体内的较高浓度药剂能起到稀释作用,也能在一定程度上减轻药
After the occurrence of phytotoxicity to take the appropriate remedial measures. Commonly used first aid measures of injury are the following: 1 spray a lot of water or microstrip alkaline water rinse. Early detection of phytotoxicity, you can quickly spray a large number of water with the leaves of the victim plants repeatedly, try to wash away the plant surface of the drug, and the increase of phosphorus and potassium, cultivating loose soil and promote root development to enhance crop resilience. At the same time, as a large amount of water leaching, the crop can absorb more water, increase crop cell moisture, the body of the higher concentration of the drug can play a dilution effect, but also to some extent reduce the drug
