When is the best time to water winter wheat (what are the benefits of watering winter wheat before winter)

Winter wheat must be watered thoroughly, but it is necessary to avoid flooding. The size of frozen water should be determined according to soil moisture. One thing to remember is that it is best to pour frozen water around 900 am-400 pm, so that there is enough time for water to penetrate. Because it is best to pour frozen water into the soil that day. Otherwise, the accumulated water will freeze at night, which will lead to poor respiration of wheat roots and death of seedlings.

The temperature is gradually decreasing in winter, so it's time for winter wheat to be watered with frozen water.

Wheat is one of the main food crops in northern China. Planting in late autumn, growing in winter and spring, and harvesting in summer. This is the longest growing crop I know.

In our country, it has become a habit to water the winter wheat with frozen water every year before freezing. So, why pour frozen water? When does this water need watering? How much water is suitable?

Why pour frozen water?

There are many advantages to pouring frozen water, which is why we should pour frozen water. The analysis has the following points:

First of all, providing sufficient moisture can better maintain the ground temperature.

The winter in the north is dry, with insufficient rainfall and snowfall, and the moisture in the wheat field is not enough to support the safe winter of wheat. After pouring frozen water, it can not only provide water for wheat seedlings, but also lay a good foundation for returning to green in the coming year.

The frozen water covers the wheat field with a "quilt", which can better keep the ground temperature and make the wheat keep out the cold in winter!

Second, change the soil structure and compact the soil.

After wheat is irrigated with frozen water, with the infiltration of water, the loose soil becomes compact, and after freezing and thawing, the soil gradually becomes granular, which is beneficial to the root system growth of wheat.

Third, eliminate pests and diseases.

In winter, pests and diseases in the field will also lurk and hide under the warm soil layer. After pouring frozen water, especially after freezing, some pests and eggs will be frozen, and some will freeze to death, reducing the harm of pests in the next spring.

When is the best time to pour frozen water on winter wheat?

When is the best effect of frozen water for winter wheat? It is important to grasp this time. It is not good to be too early or too late, and no good result can be achieved.

If the time is early and the temperature is high, the wheat seedlings are still growing and grow too vigorously, which is prone to freezing injury.

If the best time passes, it is too late, and the temperature is too low, the soil will freeze, and the poured water will not penetrate below the surface of the soil, and it will not play the role of "frozen water" at all.

When should winter wheat be watered with frozen water?

There is an agricultural proverb: "The night is frozen and the winter irrigation is just right". Generally speaking, water can freeze at night and melt into water during the day. This temperature is the best time to pour frozen water. Generally, the average daily temperature is 3-5℃, which is most suitable for pouring frozen water.

How much water should I water?

Winter wheat must be thoroughly watered, but to avoid flooding, the size of frozen water should be determined according to soil moisture.

One thing to remember is that it is best to pour frozen water between 9 am and 4 pm, so that there is enough time for water to penetrate.

Because it is best to pour frozen water into the soil that day. Otherwise, the accumulated water will freeze at night, which will lead to poor respiration of wheat roots and death of seedlings.

Summarize the wintering of winter wheat, when to water it and how much water to water it? It should be implemented according to the specific situation. Never copy mechanically, lest you be self-defeating and can't seal the frozen water.
