Greenhouse grape dense-planting and high-yield early maturing cultivating method

Abstract

The invention discloses a greenhouse grape dense-planting and high-yield early maturing cultivating method. The cultivating is performed in a vegetable greenhouse, and seven measures, such as new seedling dense planting, fertilizer and water management, trimming management of fruiting mother vines, trimming management of fruiting vines, management of grape ears, later-stage management of a grape garden, and management after fruit ear harvesting, are taken. The greenhouse grape dense-planting and high-yield early maturing cultivating method has the advantages that the single-stem and fewer-main vein grape sparse planting mode in the traditional shed frame, fence frame and T-shaped fence frame or the existing greenhouse is replaced into the greenhouse vegetable type high-density planting mode, so the grape stereo structure is simplified, the grape is cultivated in a vegetable greenhouse cultivating way, a single-branch fruiting structure mode is formed, the space structure is sufficiently utilized, the problem of unbalance growth of grape is solved, the yield contradiction between the number of grape plants and the group is solved, and a new cultivating mode with stable and high yield and annual yield exceeding ten thousand kilograms per mu is realized.

Description

technical field [0001] The invention relates to viticultural techniques in fruit and vegetable production. Background technique [0002] At present, grapes are the fruit with the largest cultivated area and the highest yield in the world. The traditional open-air viticulture production in my country mostly adopts trellis structure and trellis structure mode. With the development of production, small trellis and trellis structure cultivation models gradually appear. In the open-air cultivation, the plastic cultivation mode of grapes is constructed according to the growth potential index of grapes. The row spacing of the plants is large, the height of the rack is small, and the number of cultivated plants is small. 2 to 3 meters, and 55, 74, and 220 plants are planted per mu. At the end of the 20th century, with the rise of greenhouse vegetable production, people gradually applied greenhouses to viticulture, and a single-arm hedge cultivation or T-shaped hedge single-stem an...

Problems solved by technology

In the cultivation implementation of this model, the "single branch" fruiting habit of grapes and the shallow root characteristics of grapes are also ignored. People still regard the vigorous growth of grapes and the large growth of branches as the main factors that cannot be adjusted according to traditional habits. Passive adaptation measures are adopted, and the annual renewal of fruiting vines cannot be realized, resulting in a large amount of pruning and excessive nutrient consumption, resulting in waste of nutrients

Although it can also achieve early maturity and go on the market more than 50 days in advance, it has no obvious effect on ensuring the quality of grape fruit and increasing yield, especially for stable, high and high yield in grape greenhouse cultivation. The general yield per mu is 2500-3000 kg

Moreover, it has caused the disadvantages of high labor intensity, high labor cost and difficult management.
