Grape is one of the oldest fruit tree species in the world. It originated in western Asia and has been cultivated all over the world. About 95% of the world's grapes are concentrated in the Northern hemisphere. Grapes not only taste delicious, but also have high nutritional value.
Grapes are one of the most popular fruits. In recent years, the table grape industry has developed rapidly and the planting area has been increasing. Grape planting is very exquisite, and it is also important to master the planting skills.
1. The seedling.
Seedling grape planting will generally use the method of transplanting seedling, so before planting to dig a good seedling hole, and then put the right amount of farm fertilizer as the base fertilizer.
After the bottom fertilizer covers the soil, a moderate amount of compost can be mixed into the soil. Do a good job in advance of germination sowing, April, May transplanting preparation.
2. Water management.
We should do a good job in the management of grape seedlings. After colonization, irrigate the root water, cover with plastic film, and seal the outlet with wet soil. Controlling planting density is also important.
Do not water too much at seedling stage and water less when the soil is dry. After the seedlings are alive, you can increase the frequency of watering. If it is summer high temperature weather, to avoid watering at noon, generally in the morning and evening watering.
3. Put up the vines.
Grapes are a kind of vine fruit, so we should put up shelves when the grapes have not entered the growing season, shelves should be strong, can withstand the wind, prevent the wind from blowing away, causing damage to the plant.
When grape new branch grows TO 20 CENTIMETERS or SO, want TO do a good job guide vine work, and appropriate topdressing, control the amount of nutrition and proportion. After success, grapes are watered once every half month. Watering and weeding work together to improve soil permeability, strengthen the absorption of water and nutrients, and promote grape growth.
4. Trim well.
After viticulture, pruning and finishing are key. The aim of pruning and thinning is to regulate yield, save nutrients, increase fruit set rate and improve fruit quality.
Medium growth of the fruiting branches left 1 flower spike, a few strong branches left 2, weak branches do not leave, its leaves generally need to leave 30~40 leaves, in order to make nutrition to meet the needs of 500 grams of fruit.
5. Fruit picking.
Batch harvest, should not be picked in advance, otherwise not only the sugar content is low and not resistant to storage, harvest by hand to cut the panicle handle, do not touch the fruit surface damage fruit powder, timely boxed into the warehouse temperature storage.
The content of resveratrol in grape skin and proanthocyanidin in grape seed is higher than that in other parts of grape and also higher than that in most other fruit trees. They have very high medicinal value and have become important nutritional medicinal materials in the world.
