Spring is the season when the grape sprouts grow leaves, shoots and headings and blossoms. Strengthening the spring management of grapes can increase the yield and quality.
From late February to early March, this period is the budding period of the grape. In this stage, the water should be promptly given to the vineyard to produce nitrogen fertilizer. Conditional farmers should timely flood the entire garden to ensure that the grape plants are budding. Grape sprouting stage is also the time when the grape plant buds continue to differentiate and the new shoots begin to thrive. When large amounts of nutrients are needed, it should be blended with 0.2% urea when applying manure excretion. The amount of fertilizers accounts for about 15% of the total amount of fertilization in the whole year.
From early March to mid-to-late April, winter shoots left by grapevines after winter cutting usually have 70% to 80% germination, resulting in more germination. Therefore, reasonable sprouting should be performed after the grape plants sprout in spring. Too many buds will result in waste of nutrients and competition, which is not conducive to fruiting. Leaving the buds too low will make them prosperous and increase fruit and fruit. The specific management method is as follows:
Trimming buds: When one bud has multiple buds, one bud is left every 15 to 20 centimeters, and each bud leaves one new shoot. Each result leaves 2 to 5 new shoots, and the rest are wiped from the base. except. When the buds are applied, they are also wiped off with antherosclerotic buds or weak shoots.
Pintip binding vines: preserved shoots before flowering to leave 5 leaves above the spike topping, no shoot spikes leave 7 to 8 leaves topping. Auxiliary shoots after the pinching only left the top 1 ~ 2 axillary shoots, leaving 2 leaves repeatedly picked up the heart, the rest of the auxiliary tip all erased. At the same time, according to the growth of dendrite timely vines.
Ear treatment: In order to ensure the fruit setting rate, usually 1/4 to 1/5 of the tip of the plant should be removed, and 0.3% boron fertilizer plus 0.3% to 0.4% urea should be sprayed during the flowering period. Five days after flowering, artificial granules are made and then bagged.
Disease prevention and treatment: When the plants have 3 to 5 leaves to prevent disease, spray once every 7 to 10 days, especially after the rain should strengthen the spraying protection, and pay attention to cultivator weeding, improve ventilation conditions in the park. Blackpox can be used to control 8000 times of DuPont Fuxing, and gray mold can be used to prevent and treat 1500 times of quick keratin.
