Vineyard Winter Management Technology

Deep-sweeping the soil: In combination with the base fertilizer, the soil in the garden is deep-ripened and the drainage system is well-organized. Shizujifei: Basal fertilizers are mainly farmyard manures, supplemented by chemical fertilizers. General Mushi decomposed organic fertilizer 3000 ~ 4000 kg, potassium fertilizer 10 ~ 15 kg, 35 ~ 40 kg of phosphate fertilizer, and the organic fertilizer is fully mixed and then applied. Do not accelerate nitrogen fertilizer when applying base fertilizer. Pay attention to pruning: 1. Select the best annual branch. This new shoot is generally thick and round, with a small pith, short internodes, nodules, and branches that are yellow-brown or red-brown. On the other hand, the length of the long internodes, the large part of the pulp, the small long branches of the buds and the flat branches should be removed or extended, and should not be retained. 2. Prevent clipped buds from drying or damaging. Grape pith has a large pith, loose tissue, and easy to evaporate. Therefore, trimming should be 3 to 5 cm away from the bud. 3. Pay attention to the direction of the cut. Cut as much as possible on the opposite side of the clipped bud. 4. Note that the length of the general festival is slightly longer at the base, and the buds are smaller, and should be cut off from the base. When the vines and side vines are senescent, the sprouting twigs can be used for renewal. When the vacancies are vacant, they can make up for the racks. Clear the garden: Remove the fallen leaves and weeds, and burn them in concentrated form (do not use the leaves as fertilizer). At the same time, Baume 5 degree lime sulfur was used to spray fruit branches, poles and the ground; when sprouts sprouted in spring, they were sprayed with Baume 3 degree lime sulfur. Timely winter irrigation: In case of severe drought in winter, combined with the application of organic fertilizer, the soil becomes more dry, and winter irrigation should be performed timely.
