Planting technique of Black Barado Grape

Black Barado grape is a kind of hybrid grape, which is deeply loved by people because of its thin skin and crisp meat. At present, it can be planted in some areas. What are the planting techniques of black balado grape?

1. Greenhouse construction: build a connected plastic greenhouse with 60mm in length and 60m in width, build 3.5mi high ridges, and use arches to enhance the bearing capacity of the shed.

2. Seedling selection: black Barado grows weakly, so it is suggested that grafted seedlings such as SO4, 5BB and 1103P should improve their growth potential.

3. Seedling planting: spring and March is the best. Before planting, 5 jin of mature organic fertilizer was applied per mu, and deeply ploughed and matured, and then the fields with high 25cm were dug according to the row spacing of 3 meters. Then the seedlings are planted on the field border according to the distance of 1 to 3 meters, then covered with soil, watered and covered with film.

4. Post-planting management technology:

(1) New tip management. When a true leaf appears after the grape is planted and germinated, it begins to wipe the bud and tie it to the bamboo pole when the new shoot grows to 25-30 cm high. When the new shoot grows to 40-50 cm high, the first coring is carried out. After the coring, a strong summer bud secondary shoot is selected as the elongated shoot, and the growth is extended upward. The following summer buds leave a leaf to pick the heart repeatedly. And tie it to the shelves in time. When the new tip grows to 1.5 meters high, the second coring is carried out, and when the accessory tip at the top of the coring grows to 4 leaves.

(2) fertilization management. More bio-organic fertilizer and residue fertilizer were applied in rainy season, and slag fertilizer and manure were mainly applied in dry season, combined with bio-organic fertilizer.

(3) shaping and pruning: wipe off the overdense and weak buds on the new grape branches in early spring and fix the branches when the new shoots grow to 15-20 cm. It is appropriate to keep the distance between the branches in 10-l5 cm. In general, 2-5 leaves were left on each fruiting mother branch, only one secondary shoot at the top and one leaf on the other secondary shoots were left for repeated coring.

(4) bagging the fixed fruit. The amount of fruit is determined according to the tree potential and variety characteristics, and the hanging amount of fruit can be determined according to the ratio of leaf to fruit at 1:1. Then bagging the fruit was carried out to effectively prevent the harm of diseases and insect pests and improve the appearance quality of the fruit.

(5) pest control: when the new shoots grow to 15-20 cm high, 50% wettable powder 800 times or 70% mancozeb 600 times solution can be used to control grape downy mildew, anthracnose, black rot, white rot, brown spot and so on. In the later stage, you can spray an appropriate amount of pesticides according to the situation of the tree.

Generally speaking, Herbalado grapes are easy to grow, similar to other grapes. Please refer to the above method for planting.
