Winter wheat irrigation principle
The drought-heavy plot, or the bottom lot, is not enough, but it lacks land, and it is necessary to pay close attention to watering time to promote more wheat roots.
Prosperous wheatfields with good lyrical conditions may not be poured over winter water to control the prosperous spring.
For weak seedlings with poor fertility, insufficient fertilization, small groups, and poor growing conditions, wintering water can be poured early in late November, and combined with watering fertilizer, generally about 10 kilograms of urea is recovered to promote growth.
In general, strong seedlings and wheat fields, when the average temperature dropped to around 5°C (from the end of November to early December), it was best to pour over winter water when it was frozen overnight. Preheating at high temperatures will promote growth, and it will cause ice damage to the wheat seedlings on the ground. Complete the pouring of winter water before chilling on the wheat field. The pouring of winter water should be carried out in the sunny morning. The amount of watering should not be too large, but it must be thoroughly irrigated. It is advisable to infiltrate into the soil on the same day after the watering. Avoid flooding.
