"A layer of ice in the winter, a green in the spring." This fully shows that if the villagers, communities and households of the farmers with electric irrigation conditions can carry out the winter irrigation, they can reach a sowing every spring next year and take the whole plant once. Especially in the severe drought this autumn, winter irrigation is very important. So why can winter irrigation increase production? The first is water conservation. Due to the cold-removing effect after winter irrigation, the topsoil is formed with 1-2 cm thick false pellets, which can reduce evaporation on the ground and facilitate the storage of water. The second is no drought at the seedling stage. Due to the large amount of water in winter, even in the spring drought, the need for seedlings to maintain moisture can be ensured. The third is to loosen the soil. Without the land that has been turned over by the fall, the winter irrigation can make the moisture in the soil frozen and swell. After thawing, the surface is loosened. The temperature of the soil moisture in the soil after the winter-turning irrigation is appropriate and the role of bacteria accelerates the decay of the broken leaves, which is conducive to improving the soil fertility. The fourth is to reduce the pests and diseases. After the winter irrigation, the eggs on the surface of the soil can be rushed into the ice water and frozen to death. According to surveys of relevant departments, the incidence of wheat smut was lower by 4% than that of unfilled land after winter irrigation. The fifth is to protect the topsoil. Due to large soil moisture. It can prevent the wind from stripping the ground and reduce the damage of wind erosion. The time of winter irrigation and the quantity of irrigation should be adapted to local conditions. The soil with small soil leakage can be used during freezing to reach freezing with freezing. If it is sandy loam, 70-100 cubic meters can be filled per mu, and other soils can be filled with 60-70 cubic meters per mu. Leakage larger land mass, should be carried out after freezing, generally in mid-December to mid-January start winter irrigation. The irrigation method is: Conditional farmers are best built into rakes. Implementation of long irrigation, the distance between the ridge and the ridge width of 10-20, 20-30 cm high. It is also possible to use a ridge irrigation system or a flood irrigation system without building a concrete wall. In order to achieve the effect of winter irrigation, we must organize various farmers to prepare well-watering groups. First, we must prepare for water supply, especially for organic wells and electric irrigation stations. We must overhaul the pumping equipment and properly cover the wells for timely heating to prevent freezing of the machines. Where rivers and rivers are used for winter irrigation, dams should be maintained. Secondly, the land is well-formed and the canals are repaired so that the water flow can be unimpeded, running water can be prevented, and water leakage can be prevented. When the water transport takes a long time, it is necessary to prevent the channels from freezing and blocking water. Third, organize well-fed winter irrigation teams, prepare classes and groups, clarify the responsibility system, and supply water continuously throughout the day and night. Fourth, the water in the water source, water pipes and water tanks should be drained in a timely manner to prevent freezing injury. Use the water in the reservoir, close the gate after irrigation, use river irrigation, and block the water intake after filling. China Agricultural Network Editor
