In winter, pouring winter water not only can play the role of winter water in spring to prevent the spring drought, but also can practise soil, crush crushed rubbish, solidify cracks, ease the drastic changes in the ground temperature, prevent frozen seedlings from being killed, and help foster strong seedlings to overwinter. It can also eliminate overwintering pests, promote the activities of soil microorganisms, accelerate the decomposition of soil organic fertilizers, and create good fertility conditions for spring wheat return to green. However, most farmers' understanding of winter irrigation is inadequate. There are the following problems in winter irrigation: First, flood irrigation. In winter, when the temperature is low, the watering should be done slowly and slowly. The amount of watering should be completely infiltrated on that day, and must not be flooded. Otherwise, it may cause excessive mechanical damage due to watering too much. Frozen seedlings due to freezing. Second, rather than pouring water rather dry. Some farmers think that winter wheat can cause wheat freeze damage and wheat rooting, so no matter how dry it is in the winter, it will not dare to water the fields. When the soil moisture content is lower than the specified index (sand land Third, ignore the time choice. Some farmers in order to improve the watering efficiency of wheat fields, when watering early and late, black water, water can not be in time infiltration, in case of low temperature at night can easily make the wheat frozen or cause Ling lift, so that the wheat seedlings died due to rooting; there are to be able to borrow others The watering tools often choose to water on a windy or cloudy day. This is not worth the candle. Watering should be selected from 9am to 3pm on sunny days. Fourth, only water without top dressing. For wheat fields with insufficient base fertilizer, small groups, thin wheat seedlings, and slightly yellowed wheat fields, topdressing 5 to 7.5 kg of urea per acre should be used in combination with watering to promote seedling upgrading and transformation. Fifth, only water without cultivating. After the watering, it should be ploughed in time to remove the compaction, eliminate cracks, increase the temperature, and ensure that the wheat seedlings safely pass winter. Sixth, do not pour drought. In some local and individual plots, when the planting time is sufficient or the wintering water has been poured during the winter, the water content of the cultivated layer can also meet the current wheat growth needs. These plots do not need to be watered again. Nursing pad is a disposable sanitary product made of PE film, non-woven fabric, fluff pulp, polymer and other materials.
