How to remedy the Frost injury of Wheat

If only the leaves of wheat are frozen and the degree of freezing injury is mild, the wheat can generally resume its growth after a period of time, and special measures can not be taken to remedy it.

??? However, if the wheat seedlings are severely frozen and dead seedlings appear, appropriate measures should be taken to promote the recovery of wheat seedlings:

First, the wheat field should be suppressed in time, compacted soil to close soil gaps, increase soil compactness, improve soil moisture conservation, moisture conservation, fertilizer conservation capacity, and form strong seedlings. After suppression, vigorous seedlings can control the growth of aboveground stems and promote the development of low tillers, especially for vigorous seedlings jointed before winter, suppression can promote the transformation of prosperous seedlings to strong seedlings and increase the ability to resist stress.

The second is to supplement nitrogen and phosphorus fertilizer or spray foliar fertilizer to promote tiller formation, improve root development, cultivate strong seedlings and enhance resistance.

Third, timely winter irrigation, according to the weather forecast, irrigation horse water in the field moisture ditch before the cold current strikes, the soil can be moist, raise the temperature near the ground and leaves, form a microclimate, and can prevent or reduce freezing damage. Generally speaking, the effect of irrigation is the best 1-3 days before cooling, and the effect of choosing breeze or calm wind weather is obvious when irrigation is anti-freezing. Lin Donghua
