Cultivation method capable of postponing mature period of grape leading shoot fruits

Abstract

The invention relates to a cultivation method capable of postponing the mature period of grape leading shoot fruits. The cultivation method is characterized by: removing fruiting parent branches which are immature or have the diameter smaller than 0.5 cm after entering the fruiting period at the time of leaf falling in winter, and not pruning the preserved fruiting parent branches in winter; spraying a growth inhibitor for the first to delay the growth of new tips after spring beginning when the winter buds of the fruiting parent branches germinate to generate 8-12 cm-long new tips; pruning the fruiting parent branches when the winter bud new tips at the top of the fruiting parent branches grow to about 20-25 cm length, and preserving 1-3 winter buds at the bottom part; and spraying the growth inhibitor for the second time to delay the growth of the net tips and the formation of inflorescence when the winter buds germinate and generate 2-3 leaves.

Description

technical field [0001] The invention relates to a cultivation method for grapes, in particular to a cultivation method for delaying the ripening period of main shoot fruit of grapes. Background technique [0002] Grapes are also one of the main fruits in my country. They have the characteristics of bright fruit color, juicy pulp, unique flavor, rich nutrition, and wide application. At present, grapes are cultivated and utilized on five continents in the world, and more than 80% of grapes produced in my country are used for Fresh food, fresh table grape production is the main body of my country's grape industry. [0003] In terms of the variety structure of table grapes in my country, there are fewer early-maturing varieties and late-maturing varieties, mainly middle-maturing varieties, and the ripening time of fresh fruit is relatively concentrated. Under normal circumstances, the ripening period of fresh grape fruits ends in mid-to-late September in southern regions and mid...

AI Technical Summary

Problems solved by technology

The problem with this technology is: the main shoot fruit (primary fruit) needs to be strengthened in the process of retaining on the tree body after maturity, including soil, fertilizer and water management, pest and bird pest control, etc. The implementation of these measures increases the management cost. At the same time, some late-maturing varieties have the risk of reduced fruit quality when harvesting is delayed

The problem with this technology is that the primary fruit (secondary fruit) of winter buds or summer buds often has problems such as irregular ears, small ears and small grains, which affect the commodity rate.

The problem with this technology is that this technology is only suitable for use in high altitude and cool climate areas in my country, and the cost is relatively high
