Background

Herbicides refer to agents that kill weeds and protect crops. The herbicide has the characteristics of low cost, high efficiency, simple and convenient operation, labor saving, obvious weed control effect and the like, and is widely applied in agriculture, but the phenomenon of phytotoxicity on crops is frequently caused when the herbicide is improperly used, and the phytotoxicity on the crops can be caused when the herbicide is excessively used, the herbicide is improperly mixed and used, and abnormal and poor environmental conditions and the like. Herbicide damage results in abnormal growth of crops, stem and leaf distortion, clumping, dwarf plants, flowers without fruits, and even dead seedlings with reduced yield. The yield of the herbicide is reduced by 10-40% for the case with light phytotoxicity, and the yield is no longer ensured for the case with heavy phytotoxicity. With the development of agricultural science and technology, the application area of the herbicide in agricultural production is larger and larger, and the herbicide hazard brings serious threat to the agricultural production safety. In the field of herbicide phytotoxicity detoxification research, the current method is as follows: the method comprises the following steps of washing with clear water, applying seedling fertilizer early, applying quick-acting fertilizer, enhancing intertillage and loosening soil, applying special antidote (such as isoxadifen, cyprosulfamide, mefenpyr, cloquintocet, naphthylamine and the like), spraying alkaline substances such as sodium bicarbonate water and the like, but the method only has the effect of relieving slight herbicide hazard and has no effect on serious herbicide hazard. In addition, the methods are remedial measures taken after the herbicide hazard occurs, and the problem of the herbicide hazard is not fundamentally solved.
