Wheat remediation measures
1, watering fertilizer
Maintaining sufficient soil moisture and moistening the field is of great importance for preventing and remediating low temperature and freezing damage. Immediately before or after the onset of low-temperature freezing injury, immediate nitrogen fertilizer and watering should be applied to promote small tillers and spikes, increase tiller percentage, and compensate main stem losses. Generally, about 10 kilograms of urea are applied per acre, and the amount of topdressing can be increased as appropriate for the frozen wheat fields, but the maximum amount is not more than 15 kilograms per mu.
2. Foliar spraying plant growth regulator
Spraying plant growth regulators can maintain the stability of the plant cell membrane, improve the wheat's resistance to stress, and can repair the damage caused by low temperature on wheat, and have certain effects on the prevention and mitigation of cryogenic freezing injury. After freezing and freezing injury, spraying plant growth regulators such as Tianda-2116 (Zhuangmiaoling) on ​​the surface of frozen wheat leaves has a significant role in promoting the recovery of wheat, and the rapid growth of medium and small tillers is reduced to a spike.
