1) Strengthen field management. Timely watering, adding ammonium bicarbonate or urea and other fast-acting fertilizers, promote corn roots to absorb more water, improve the metabolism of corn and the speed of nicosulfuron degradation in the body, and promote corn as soon as possible to restore normal growth and development. Appropriate cultivating, increasing the permeability of the soil, and enhancing the ability of the maize root system to absorb water and nutrients. 2) Spray plant growth regulators or foliar fertilizers. After the dew is dry in the morning or in the evening, foliar spray is performed with a 50 to 200 ml/L gibberellin (920) solution or 1% to 2% urea water and 0.2% to 0.3% potassium dihydrogen phosphate solution, which can effectively reduce Drug damage, promote the normal growth of corn. 3) For some herbicides that are easily decomposed and degraded by alkaline substances, the crop can be sprayed with 0.2% quick lime or 0.2% sodium carbonate diluted water solution, with good results. Should also be sufficient irrigation, promote root absorption, reduce the concentration of drugs in crops, and ease the injury. Excessive application of drugs can effectively reduce the harm of drugs. 4) to reduce or avoid corn stems and leaves herbicide harm, simple and easy measures are directed or semi-directional spray; remedy corn stem and leaf herbicide harm, the most effective measure is to strengthen the management of fertilizer and water. The measures adopted for the injury and damage of herbicides in corn field stemmed from the following: 1) Maize "whip-like" and "fist-like" injury. This type of situation is a heavy corn injury, and it is unrealistic to recover the normal growth of the affected corn. The best remedial measures are to artificially assist in lifting the external appearance of "whiplash" and "fist-like", and then fertilize the water, and in combination with spraying foliar fertilizer or growth regulators, can receive significant results. If this measure is not adopted, other measures will have little effect. 2) Dry stems and leaves of corn are more severe, but the heart has not yet died. This type of situation is a contact-killing phytotoxicity, the most effective measure is to fertilize first, then water, especially topdressing available nitrogen. Through the above remedial measures, corn generally does not reduce production. However, spraying only growth regulators and foliar fertilizers is not satisfactory 3) General light injury. Including the appearance of chlorotic spots in corn leaves, mild fading growth inhibited. The preferred measure is to enhance fertilizer and water management. If there is no watering condition, only foliar fertilizers and growth regulators can be sprayed and certain effects can be obtained. Commonly used such drugs are PNS, Nai'an, Gibberellin, KH2PO4, urea, etc., which should be reasonably selected according to specific conditions.
