How to water the solar term wheat?

Wheat is watered with wheat, because the area where wheat is planted is relatively wide and the climate is different from place to place. For example, some places freeze early, while others freeze late. So the time of pouring frozen water is different. For example, in our local area, frozen water is usually poured between light snow and heavy snow, because after watering, a frozen layer will form on the soil surface in the morning and evening, and it will be thawed properly at noon, on the one hand, wheat will not grow vigorously; On the other hand, it is beneficial to protect wheat from freezing injury. Watering wheat at the beginning of the winter solar term depends on the actual situation.

(Weak seedlings that need watering and fertilization)

Wheat suitable for irrigation in beginning of winter

1 Poor water content: After the previous harvest, the water content was average, or it was planted in dry land after a light rain, but the planted wheat barely emerged. Because of the limited moisture in the soil, the roots of the seedlings can't be tied, and the nutrients in the soil can't be absorbed, forming weak seedlings, which can't reach the standard of strong seedlings when they are frozen. At this time, water is needed to meet the needs of seedling growth.

2 Less sowing amount: When wheat is planted, due to various reasons, such as low seed germination rate, burning seeds with chemical fertilizer, substandard or poor water content, the emergence rate is low, so it is necessary to water in time to improve tillering rate, reach the number of plants per mu and prevent yield reduction.

3 Look at the growth: the planted wheat is poor and sparse, and its tillering ability is poor after emergence, so it needs to be watered in time when the soil is dry; At the same time, topdressing urea and other quick-acting nitrogen fertilizers to raise seedlings.

(Planting is too dense to water)

In short, the above three conditions are suitable for watering before and after beginning of winter, and the seedlings become stronger from weak. So, under what circumstances is it not suitable for watering?

1 Not suitable for beginning of winter watering when wheat is planted too closely: after wheat is planted too closely, control watering, reduce tiller number, prevent root system from growing and falling down, and prevent seedlings from growing vigorously and causing freezing injury before winter. It is good to turn green in early spring, because there is a saying that "the wheat is not prosperous" to prevent the vigorous growth years ago and the formation of weak seedlings after turning green.

2. The already flourishing wheat is not suitable for watering in beginning of winter: when planting wheat, the soil moisture is good, the fertility is sufficient and the temperature is suitable. Due to early planting and other reasons, the seedlings all grow vigorously. In this case, do not water, but postpone watering to control the vigorous growth of wheat seedlings.

(After the Spring Festival, water it in time after it turns green)

In a word, watering wheat at the beginning of winter should be based on the local climate and wheat growth. When the seedlings are flourishing, control the wheat to be frozen after the seedlings are strong; When the seedlings are weak, promote the seedlings to grow into strong seedlings. It is not only conducive to safe wintering, but also conducive to turning green in spring. Achieve the purpose of increasing production and income.
