1, fast fruiting: the whole tree has only one main vine and four fruiting branches, and full and sufficient flower buds can be formed in the first year of planting, and the harvest can be obtained in the second year after planting.

2. High yield: the fruiting position is stable between 1 and the second iron wire, never moving up, with few trunk branches, short nutrient paths, less nutrient waste and double hedges, so the yield is high.

3. Good quality: Prune long branches and make full use of the plumpest flower buds in the 3rd-8th section, so the fruit ear is large, the fruit setting rate is high, the fruit grains are neat and the ear shape is compact.

4. Easy to manage: the results are consistent locally and the height of new vines is consistent, which is convenient for production management. There is only one fruiting vine per plant, so the main vine is thick and slow, which is convenient to be buried underground for cold protection.

Second, the small dragon pole technology of scissors in the first winter:

1, the first line is 60cm from the ground, which is the main stem, and the upper and lower tips have been cut off.

2. The part of the trunk extending forward is the fruiting vine, and the length of the cut leaves is equal to the plant spacing.

3. As a result, when the winter buds on the mother vine are not full, there are only two buds left in the secondary branch of this node. As a result, when the winter buds on the mother vine are full, the secondary branches on the nodes are cut off.

Members of Zheng Hao Grape Planting Cooperative in Peixian County, Jiangsu Province adopt new technology. In the first year of planting, the yield per mu can reach about 5000 kg in the second year and 15000 kg in the third year.

However, there are some shortcomings in the cultivation techniques of Xiaolonggan grape. For many years, many fruit farmers have been using fan-shaped pruning in grape management. Planting for one year, aborting for two years, and after three years, it is a big drawback of grape production, which is small high yield, long cycle and slow effect.

In recent years, a grape management technology called main stem type has become a revolution in grape production. It builds a garden in one year and produces high yield in two years! Its technical core is to change the original three-fork branch fixing technology into one-fork branch fixing technology, and to change the main branch of the sector into one-fork long spoon pruning. Originally, I was worried that the result part would move outward and the short and medium buds had to be retracted. Now I have lost weight directly. At the same time, I cultivate four robust vegetative branches every year as fruit branches in the coming year, and there are new fruit branches every year, so I don't have to worry about the years. I changed the complicated fan-shaped binding into a simple single-arm plastic binding, replacing the complicated and difficult binding in the past.
