Spring is the season when the grape buds spread out, and the elongation and heading and flowering of the branches spread. The spring grape management is strengthened to increase the grape yield and quality. In the budding stage: irrigation with buds and applying nitrogen fertilizers quickly, conditional orchards should be filled with water in a timely manner to ensure budding and neatness. In addition, it is at this time that flower buds continue to differentiate and new shoots begin to prosper. When large amounts of nutrients are needed, it is necessary to apply decomposed human urine mixed with 0.2% urea. The amount of fertilizer this time is about 15% of the whole year. Buds, shoots, spikes and pest control. After winter pruning, the winter buds on the mother tree 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, making the tree weak, is not conducive to fruit setting; However, if too few buds are left, it is easy to promote vigorous growth of branches, resulting in serious flowering and fruit drop, so pay attention to shoot buds shoot. Stubbles: Usually when one bud has germinated on one parent, one bud is left every 15-20 centimeters, leaving 2-5 new shoots per mother branch and the rest wiped off from the base. When the buds are wiped, the apical buds or weak buds in the two buds are generally erased, and only 1 shoot is left 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. Pinpointed vines: Before the flowering of the preserved shoots, leave 5 leaves above the panicle topping, and leave the shoots to leave 8 leaves topping. After topping, a large number of axillary shoots will be sprouted, leaving only 1-2 apical shoots at the top and leaves 2 leaves repeatedly topping, and the rest of the auxiliary shoots will be wiped off. At the same time, it is necessary to tie the vines according to the growth of vines. Spike processing: In order to ensure the fruit setting rate, one-fifth of the panicle spike is usually removed manually and 0.3% boron plus 0.5% urea is applied during the flowering period. Five days after flowering, artificial fruit thinning was performed on the ear with more results and then bagged. Cultivated weeding and disease prevention and control: The grape begins to prevent disease when it germinates 3-5 leaves, spraying once every 7-10 days, especially after the rain, it is necessary to strengthen spraying protection and pay attention to cultivating and weeding. This period is mainly to prevent grape black spot disease, gray mold, rust and so on. 3 Ply Breathable Face Masks,Non-Woven Disposable face Mask,Medical Disposable Face Mask,Medical Disposable Face Mask Dongguan Keyutai Mask Co., Ltd. , https://www.maskkytai.com
