Since the autumn last year, there has been no effective precipitation in the northern winter wheat region for four consecutive months. After the Spring Festival, the temperature will gradually rise. In addition, more gale winds in the north will increase the rate of soil loss. If drought is not promptly watered, some wheat fields will cause drought due to drought. If there is no effective precipitation before and after the Spring Festival, various wheat households must prepare for drought and watering, and resist drought and water in time after the Spring Festival. First, the degree of arid wheat field looting wheat field without watering winter water; autumn, poor soil quality of soil preparation of wheat field; straw returned to the field, poor quality of wheat fields, all showed different degrees of drought. The more of the above three factors, the more severe the drought in wheat fields. II. Watering Time of Dry Wheat Fields The time of watering drought wheat fields should be determined according to the drought conditions. Above the wheat tillering festival is dry wheat field, and the watering time should be at a sunny day above 3°C on the average daily temperature of 10°C. It will be carried out until 16:00. At the same time, it is important to use frozen soil as an important basis for watering. If you do not wait until the permafrost is opened to water, it will easily lead to water accumulation in the field, freezing, and cold. This will result in the formation of “cold feeding water†and will lead to stagnation of the growth of the wheat seedlings or delay the reproduction of “little old seedlingsâ€. A simple and easy test method, that is, whether to open it with a stick of fire. Below the tillering section of wheat, dry soil and severely droughty wheat fields should be properly watered 3 to 5 days in advance. In fertile wheat fields, a small amount of available nitrogen fertilizer can be applied with water. Even in the same area, the soon-to-be-frozen tundra will not be consistent due to different factors such as the year, temperature, soil quality, topography, and seedlings. In Ningjin County, Shandong Province, the general year is around mid-February, but the date of the start of watering should not be based on "regular", but should be completely frozen ground. Third, the drought watering method of wheat in early spring when the temperature is low, cold weather and more, can not take a flood irrigation method, should use "Little White Dragon" plastic soft water for irrigation. When watering, it is necessary to finely fill the small water and pour it thoroughly. When watering, pay close attention to the weather changes. If there is a strong cooling in the forecast, stop the watering immediately. After the cold wave weather, raise the temperature and then pour it to prevent freezing. Fourth, the cultivator will increase the temperature and ensure the water level of the wheat fields after the watering. Cultivator draw hoe can get rid of compaction, loosen the soil after watering to bridge cracks, increase in temperature, soil water. The ploughing and ploughing should be carried out with clear and windless weather to increase the warming effect and promote the growth of wheat. Note that the depth of ploughing in early spring should not be too large to prevent root injury.
