Vitis vinifera flower-fruit retention method

Abstract

The invention provides a vitis vinifera flower-fruit retention method and belongs to the technical field of grape planting. The method includes following steps: (1), in a grape growing season, applying organic fertilizer into a grape orchard by 1400-1600kg / mu; (2), in 5-10 days before grape enters an initial flowering stage, performing main tip pinching and inflorescence finishing on grape plants;(3), 1-2 days after a grape end flowering stage, topdressing instant compound fertilizer by 20-80kg / mu; (4), in 3-4 days after the grape end flowering stage, putting cluster into a growth regulator for soaking for 3-8s. Fertilizer-water regulation, tree vigor regulation and hormone treatment technologies are integrated to prevent flower-fruit falling of vitis vinifera. The method is simple in operation and good in effect; grape fruit setting rate can be about 35% higher than 25% which is the fruit setting rate of conventional cultivation; the grape is uniform in fruit grain and excellent in fruit coloring, and sugar content can reach 19-20% (which is basically consistent with that of conventional cultivation methods).

Description

technical field [0001] The invention relates to the technical field of grape planting, in particular to a method for preserving flowers and fruits of giant rose grapes. Background technique [0002] The giant rose grape is a hybrid of Europe and America, which was bred by Dalian Academy of Agricultural Sciences. The parent is Shenyang Rose×Jufeng. The fruit of the giant rose grape is purple-red, the flesh is soft, the quality is high, the content of soluble solids is high (up to more than 20% after the fruit is fully ripe), and it has a strong rose fragrance, which is very popular among people. Due to the low natural fruit setting rate of this variety, the cluster tends to show sparseness, which affects the overall appearance quality of the cluster and has a negative impact on the production of Jumbo Rose grape. [0003] At present, most of the production methods for protecting the flowers and fruits of the giant rose grape are hormone treatment, tree vigor regulation, or s...

Problems solved by technology

Due to the low natural fruit setting rate of this variety, the fruit ears tend to show sparse phenomenon, which affects the overall appearance quality of the fruit ears and has a negative impact on the production of giant rose grapes.

[0003] At present, most of the production methods for protecting the flowers and fruits of the giant rose grape are hormone treatment, tree vigor regulation, or strengthening fertilizer and water management. Although the fruit setting has improved to a certain extent, it still cannot meet the requirements of high-quality fruit production. need
