Spring grape management pay attention
Spring is the season when the grapes sprout, and the elongation, heading, and flowering of the branches and branches are increased. The strengthening of grape management in the spring will increase the grape yield and quality. First, in mid-to late February to early March, budding: irrigation water, application of nitrogen fertilizer. Second, from March to mid-April: Fixing shoots, wiping buds, flower ear processing and pest control. 1. Trimming buds: Usually when a single bud has germinated on one parent, one bud is left every 15-20 centimeters, leaving 2-5 new shoots for each result, and the rest are wiped from the base. When the buds are wiped, the apical buds or weak buds in the two buds are generally wiped off, leaving only one shoot in one bud. Of course, in order to ensure the yield, it is also possible to decide whether to leave the first coil when the new shoot grows to 4-5 leaves, but this wastes more nutrients. 2, fixed tip binding vines: the preserved shoots before flowering in the spike to leave 5 leaves topping, and no flowers to leave 8 leaves topping. After topping, a large number of secondary shoots were sprouted, leaving only 1-2 apical shoots at the top and leaving two leaves repeatedly topping. The rest of the auxiliary shoots were all erased. At the same time according to the growth of vines tied vines. 3. Treatment of flower ear: In order to ensure the fruit setting rate, one-fifth of the panicle spike is usually removed manually and 0.3% boron fertilizer plus 0.5% urea is sprayed during the flowering period. Five days after flowering, artificial fruit thinning was performed on fruit trees with more fruits and then bagged. 4. Cultivated weeding and disease prevention and treatment: The grape begins to prevent disease when 3-5 leaves are sprouted, spray 600-800 times of new high-fat film every 7-10 days, especially after the rain, we must strengthen spraying protection, and pay attention Weeding and weeding. This period is mainly to prevent grape black spot disease, gray mold, rust and so on. If germs have been used, commonly used drugs, carbendazim 800 times + 600-800 times the new high fat film treatment.

The conditional orchards at this stage should be filled with water in a timely manner to ensure that they are budding. At this time, it is the time when the flower buds continue to differentiate and the new shoots begin to thrive. When a large amount of nutrients is needed, the human feces and urine is mixed with 0.2% urea. The amount of fertilizer this time is about 15% of the whole year.
After winter refurbishment, the winter buds on the mother twigs usually have 70% to 80% germination, and care should be taken to keep the buds. Too many buds remain, it is easy to waste nutrients, weak tree vigor, is not conducive to fruit setting; However, if too few buds are left, it is easy to promote the growth of strong twigs, and it is easy to severely drop flowers and fruit, so we must pay attention to wiping shoots.
