High-quality grape cultivation method

Abstract

The invention provides a high-quality grape cultivation method. The high-quality grape cultivation method comprises the steps that in a gutter-connected greenhouse, Beda rootstocks are selected, planting ditches are dug to improve soil, then planting tables are made according to the row spacing, and a row of grape plants are planted on each planting table; an iron wire net horizontal frame is horizontally arranged at the position, 1.75 m away from the ground, in the greenhouse, pinching is carried out when grape trunks grow to the position 1.6-1.7 m away from the ground, so that the grape trunks branch out main vines towards the two sides correspondingly, fruiting branches are reserved on the two sides of each main vine, and only one string of fruits are reserved on each fruiting branch; and when six complete leaves grow from young shoots of the fruiting branches, pinching is carried out to stop growth of the young shoots, and nutrition supply is transferred to clusters. The high-quality grape cultivation method has the advantages that high-platform thin planting is achieved, growth of grape roots can be controlled, and vigorous grape root systems are avoided; and the T-shaped shaping and horizontal frame type mode is combined, so that the tree body loading capacity is reasonable, the leaves are evenly distributed, sufficient photosynthetic products are provided for the plants,grape peels are bright, the color is bright, the fruit grain size is uniform, the soluble solid content of the grapes is high, pulp juice is rich and sweet, and the grape quality is high.

Description

technical field [0001] The invention relates to a cultivation method of high-quality grapes. Background technique [0002] As a bulk fruit in Liaoning Province, table grapes are favored by consumers because of their good appearance, flavor and rich nutrition. However, with the improvement of living standards, people are increasingly demanding high-grade and high-quality grapes. However, the quality of grapes sold on the market is uneven. Less and sour. After research, it was found that the defects of the traditional grape cultivation mode are the important factors that make the quality of the grapes different, which are mainly manifested in the following aspects: [0003] (1) The climate environment has a great influence on the growth and quality of grapes. The Liaoning area belongs to the semi-arid monsoon continental climate in the northern temperate zone. The annual precipitation is 450-650 mm, most of which are concentrated in August and September. At this time, the r...

AI Technical Summary

Problems solved by technology

Excessive dense planting, dense rows, uneven distribution of grape leaves, leaf cut-off rate cannot meet the growth needs of grapes, and the plant load is too large in the link of uncontrolled yield. Generally, the soluble solid content of grapes is between 14- Around 15%, the quality is not high

[0005](3) Flower and fruit management is not in place, tree nutrition regulation, fruit picking is not scientific

The traditional grape cultivation technology still adopts the management mode of branches and tendrils, resulting in too many branches per unit area, unreasonable tree load, closed canopy surface, poor ventilation and light transmission, affected inflorescence pollination, and leaves cannot get enough light. Body nutrition imbalance, fruit quality reduction

In addition, the nutritional regulation of the tree body is not fine, the supply level of nutrient elements for topdressing is low, and the fruit does not receive sufficient nutrients, resulting in low quality of grape fruit

[0006](4) Excessive application of pesticides, fruit safety questioned

Due to the excessive reliance of farmers on pesticides in production management, the excessive use of pesticides often causes pesticide residues to exceed the standard, which reduces the quality of fruits
