The benefits of winter irrigation can make the soil increase water storage and prevent drought in the coming spring. This method is commonly used in the cultivation of winter wheat in northern China to achieve the purpose of increasing production. In order to have a good winter irrigation effect, three factors must be considered: soil moisture, temperature, and seedlings. Soil Moisture Considering soil moisture, if it is less than 70% of the field capacity (less than 16% for the combined soil and less than 18% for the silt), winter irrigation is required; if it is higher than 70%, winter irrigation or non-winter irrigation may be appropriately delayed. However, it is necessary to strengthen the measures for soil loosening and soil conservation, increase the temperature of the ground, and promote the lowering of the roots of wheat to cultivate strong seedlings. temperature The suitable temperature for winter irrigation is about 3°C ​​per day. If the winter irrigation is too early, the temperature is still high and the evaporation is large, which will not achieve the effect of water irrigation and mashing. At the same time, it will cause the wheat seedlings to grow in length and not resist freezing. The winter irrigation will be late, the temperature will be low, the soil will freeze, and the water will not infiltrate. The occurrence of Lingtai will cause the wheat seedlings to freeze or suffocate. After the winter irrigation, the cold current came and when the temperature dropped below 0°C, the winter irrigation was higher than the ground temperature without winter irrigation, which was greatly beneficial to ensure the safety of winter wheat seedlings. Seedlings The seedling condition during winter irrigation is also an important condition for considering whether to perform winter irrigation. Wang Miao generally does not lack water and fertilizer, do not have winter irrigation. Weak seedlings (especially late-seeding wheat and single-rooted seedlings) are also not suitable for winter irrigation to prevent silt seedlings, Lingtai, freeze-infested wheat seedlings, and even dead seedlings. For such weak seedlings, the winter water can be turned back to Qingshui, and the water can be used to adjust the fertilizer, and the fertilizer can be used to attack the seedlings, so that the wheat seedlings can turn from weak to strong. Note: 1. The amount of winter irrigation should not be too large, so as to avoid water in the ground area and form ice shells in case of low temperature, causing the plants to be frozen in the ground, suffocating the roots, and dying after giving birth and reducing production. 2. After winter irrigation, loose soil must be cut in time to avoid the occurrence of crack damage due to soil compaction. Late sowing must pay special attention. In addition to protecting soil to prevent cracking and aeration of the soil, it can also increase the ground temperature by 0 to 10 centimeters to about 1 degree Celsius, which is conducive to promoting seedling growth. Winter wheat irrigation can greatly increase the soil moisture, increase the survival rate of wheat seedlings, and finally achieve the effect of increasing production and income.
