Answer: In order to ensure that the grape plants can survive the winter safely and ensure their vigorous growth in the coming year, reasonable fertilization and winter irrigation are required. The basal fertilizer application should be carried out after cleaning the garden, and the fertilizer is mainly decomposed organic fertilizer. Dig a fertilization ditch about 20 cm along the root of the grape plant. The width of the fertilization ditch is 40 cm, and the depth is 60 cm. The organic fertilizer is evenly spread in the ditch. Generally, 3000-4000 kg of decomposed organic fertilizer is applied per mu. The fallen leaves and weeds in the garden can also be backfilled into the ditch as fertilizer and then filled with soil. Applying organic fertilizer can supplement plant nutrition, improve the physical and chemical properties of the soil, and can also increase the ground temperature and prevent root damage from freezing. After applying organic fertilizer, you can start winter irrigation, just pour water into the fertilization ditch. The amount of watering is subject to the natural absorption of the soil and no accumulation of water on the surface. Irrigation in winter can also increase soil temperature, prevent freezing damage, and at the same time help decompose fertilizer and absorb roots, creating good conditions for growth and development in the second spring.
