Technique for cultivating non-polluted seedless grape

Abstract

The invention relates to a non-polluted grape culture technique of seedless grape; the main steps are as follows: a first step: conventional management is carried out in prophase; a second step: from 15 days before blooming to 1 week before blooming, 15-20mg/L of GA3, 10-25mg/L of 4-CPA, 1g/L of KH2PO4 and an NO.1 synergist are adopted for dipping fruit cluster; a third step: 10-20 days after blooming, 15-20mg/L of GA3, 25mg/L of 4-CPA, 1g/L of KH2PO4 and an NO.2 synergist are adopted for dipping fruit cluster; other management is operated according to conventions. By carrying out seedless treatment on seedy grape, the method can delay the formation of grape megaspore, affect the normal fertilization process, and promote seed abortion to form parthenocarpic seedless fruit; meanwhile, the method can remarkablely reduce pesticide dose, and ultimately realize the purpose of pollution-free and seedless cultivation, thus having remarkable social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of pollution-free cultivation of fruit trees, in particular to the pollution-free and seedless cultivation technology of grapes. Background technique [0002] Grapes are perennial deciduous vines of the genus Vitis in the family Vitaceae. There are more than 70 species in this genus, and about 35 species are distributed in my country, but only a few species are used for cultivation or as rootstock in production. Grapes have rich nutritional value and good health care functions, and can also provide raw materials for the food industry. Because of its excellent color, fragrance and taste, wide application and strong adaptability, it has become one of the world's important fruit tree species. Its cultivation area and output have always been at the top of the world's fruit production, and it is listed as the world's second largest main planted fruit tree. [0003] my country is one of the origins of grapes. In...

Problems solved by technology

[0007] In view of the immature denuclearization technology for seeded varieties in the above grape production, serious economic losses for fruit farmers, low benefits, abuse of plant growth regulators, and lack of science and standardization The pollution-free and seedless cultivation of seeded varieties of grapes is the key to the cultivation of grapes in Sichuan and other places, and it is also an important trend in the development of the grape industry.
