The remedial measures that can be taken for the occurrence of phytotoxicity in corn are mainly to improve the root environment of the crop, promote the growth of the crop, and increase its resilience. Take farming measures, loosen soil, increase ground temperature and soil aeration. According to the growing trend of crops, apply some quick-improving nitrogen, phosphorus, potash or other trace fertilizers. Foliar fertilization is better and the fertilizer effect is faster. It is also possible to spray some plant growth regulators that encourage and strengthen, especially to promote root growth. However, according to the needs of crops, they must not be arbitrarily used, otherwise they will be counterproductive. If there is water on the ground, remove it as soon as possible; if pests and diseases occur, they should be treated as soon as possible. In short, as long as the measures conducive to the growth and development of crops are conducive to alleviating phytotoxicity and reducing losses. 1. For the pesticide damage caused by the excessive use of soil treatment herbicides, cultivator can be used to reduce the harm caused by cultivator, continuous irrigation and drainage, and repeated flushing, and a certain amount of lime powder can be applied during watering. Neutralization of acid herbicides, whereby the residual chemicals are washed out, reducing the residual herbicide content in the soil. At the same time, strengthen field management and enhance corn resistance. Second, strengthen field management, and promote seedlings to grow quickly. In combination with watering, increase the availability of available manure, ammonium bicarbonate, ammonium nitrate, urea and other quick-acting fertilizers to promote root development and regeneration; strengthen the cultivating loose soil, remove soil compaction, promote beneficial microbial activities, and accelerate the decomposition of soil nutrients, Enhances the ability of roots to absorb nutrients and water, so that the plants can restore growth and development as soon as possible, and reduce the damage caused by phytotoxicity. At the same time, it is also possible to spray 1%-2% urea or 0.3% potassium dihydrogen phosphate solution on the foliage to promote the growth and development of the crop and restore growth as soon as possible. Third, spraying plant growth regulators or antidote against different agents. Plant growth regulators have a good stimulatory effect on corn growth and development. At the same time, they can also use zinc, iron, aluminum and other micro-fertilizers and foliar fertilizers to promote crop growth and effectively reduce drug damage. Common plant growth regulators include gibberellic acid, vinegar vinegar, and sodium nitrophenolate. 4. Spraying antidote can reduce or eliminate the poisoning of grasses to crops. For example, tea blends are selective seed dressing protectants that can be absorbed by the seed and protect the corn from herbicides such as acetochlor, butachlor and isopropyl alachlor. V. Remedy and destroy seed in time. For those fields where there is no remedy for serious injury, we must take the time to replant and replant the crop to make up for the loss. Sweeteners are Food Additives that sweeten soft drinks. Sweeteners can be divided into nutritional sweeteners and non-nutritional sweeteners according to their nutritional value. According to its sweetness, it can be divided into low sweetness sweetness and high sweetness sweetness I flavor; According to its source can be divided into natural sweeteners and synthetic sweeteners. Natural sweeteners include stevia, grosvenin, licorice, disodium glycyrrhizinate, tripotassium glycyrrhizinate and trisodium.
