Spring is the season when the grape sprouts to spread leaves, shoot elongation, heading and flowering. It is a common concern for fruit growers to strengthen spring grape management and increase grape yield and quality. The following focuses on the main management of the March-April grape. From March to mid-April: Fix shoots, wipe buds, spikes, and pest control. 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. Therefore, we must pay attention to wiping shoots. When the buds often have one bud on the mother bud, germination occurs every 15 to 20 centimeters, leaving 2 to 5 new shoots per mother tree, and the rest are wiped from the base. When the buds are wiped off, the apical buds or weak buds in the two buds are generally wiped out, and only one shoot is left in one bud. Of course, in order to ensure the yield, it is also possible to determine whether to leave the first coil when the shoot length reaches 4 to 5 leaves, but this wastes more nutrients. The tip of the preserved tip of the vine was left with five leaves above the flower head before flowering, and 8 leaves were left without flowers. After topping, a large number of secondary shoots were sprouted, leaving only 1 to 2 apical shoots on the top and leaves 2 leaves repeatedly topping. The rest of the auxiliary shoots were all erased. At the same time according to the growth of vines tied vines. Treatment of Flowering Ears To ensure fruit setting rate, one-fifth of the panicle spikes are 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 fruit trees with more fruits and then bagged. Cultivated Weeding and Disease Control Grapes begin to prevent disease when they germinate from 3 to 5 leaves, spray once every 7 to 10 days, especially after the rain, they must strengthen spray protection and pay attention to cultivating and weeding. This period is mainly to prevent grape black spot disease, gray mold, rust and so on. For example, black pox can be used DuPont Fuping 800 times liquid, gray mold can be used to control the speed Ke Ling 1500 times. In addition, commonly used drugs can also be used, such as carbendazim 800 times, mancozeb 800 times, 800 times and other agents such as zinc control. Black Goji Berry is rich in protein, fat, sugar, free amino acid, organic acids, minerals, trace elements, alkaloids, vitamin C, B1, B2, calcium, magnesium, copper, zinc, manganese, iron, lead, cobalt, nickel, cadmium, chromium, potassium, sodium and other nutrients. Been scientifically tested that the content of calcium, iron, niacin is respectively 2.3, 4.6, 16.7 times of red Goji Berry, especially procyanidins than blueberries(Black goji berry contain procyanidins is 3690 mg / 100 g; blueberries contain procyanidins is 330-3380 mg / 100 g). This is the highest ever discovered procyanidins content of natural wild fruit, which is the most effective natural antioxidant, its efficacy is 50 times of VC and 20 times of VE, the vitamins, minerals and other nutrients content is also higher, medicinal and health care value is much higher than ordinary red Goji berry, known as "soft gold".
