In order to ensure a good harvest of summer food next year, if the soil is not empty and the fields are lacking, winter irrigation must be carried out. At present, the best time for winter irrigation has passed, we must master the watering method and scientific watering.
One is the condition of winter irrigation. It is necessary to look at the sky, see the earth, and watch the air. Seeing the sky is to choose sunny weather; to see the ground is to look at the soil moisture, not watering the winter water, soil moisture content is lower than the index (sand land <12%, soil land <14%, clay land <16%), must be carried out Winter irrigation; the suitable temperature for winter irrigation is about 3 °C, the temperature is lower than 3 °C, there is a threat of freezing damage after irrigation, the temperature is lower than 0 °C, the freezing damage is more serious, in addition to freeze-dried stems and leaves, it will form "Lifting the phenomenon" caused the mechanical damage of the wheat seedlings.
The second is winter irrigation time. Try to choose sunny weather, from 9 am to 3 pm. The amount of water should not be too large, but the water should be poured evenly, but it should be poured into the soil on the day of irrigation. Avoid flooding with large water to prevent the formation of “Linglift†wounds.
The third is reasonable topdressing. For wheat fields without application of base fertilizer or insufficient base fertilizer, small population, thin growth of wheat seedlings and yellowing of leaves, 5-7 kg of urea should be applied per acre combined with watering to promote the transformation and transformation of seedlings.
The fourth is cultivating and warming. After watering, it should be timely ploughed, remove the knot, eliminate cracks, spray new high-fat film to keep warm, water-proof evaporation, sun-proof and drought-resistant, anti-soil layering, suffocation and isolation of pests and diseases to ensure safe wintering of wheat seedlings.
