What should I do if the wheat is damaged by freezing?

If the freezing damage is not heavy, do not blindly fertilize and water the water. It is necessary to promote the temperature increase, and then generate new roots and then water; if the freezing damage is heavy, you can water and fertilize early to prevent the young ears from dehydration and death. Young ears have been subjected to frozen wheat fields, and should be applied with quick-acting nitrogen fertilizer, 10-13 kg of ammonium nitrate per acre or 20-30 kg of ammonium bicarbonate, combined with watering and cultivating loose soil to promote the recovery of frozen wheat seedlings as soon as possible. In addition, due to the high nutrient consumption of frozen wheat, it is prone to premature senescence in the later stage. On the basis of topdressing in spring, the growth and development of wheat seedlings should be observed. According to their needs, appropriate amount of topdressing should be carried out during jointing or picking. Hydrogen potassium foliar spray fertilizer promotes large grains and large grains and increases grain weight.
