A kind of cultivating method of grapes harvesting twice a year and cultivating secondary flowers

Abstract

The invention discloses a method for cultivating secondary flowers of grapes harvested twice a year and belongs to the technical field of grape cultivation. In the present invention, 5-10 days after the first fruit is harvested, the fruiting branches and vegetative branches of the current year are uniformly retracted and trimmed to the 8th node position, and the re-cultivated new shoots are used to cultivate and form secondary flowers, which not only has a high rate of flowering branches, but also The flowering period is neat, which is conducive to ensuring high yield; it also increases the space for the growth of branches and leaves, which is conducive to the production of high-quality secondary fruits; and the operation and management are simple and labor-saving, which is conducive to improving production efficiency. The method of the present invention is suitable for producing two-generation fruits in two generations of different halls for early-maturing varieties in areas where the annual average temperature is lower than 20°C, and is also suitable for producing two-generation and different halls for early-, middle-, and late-maturing varieties in areas where the annual average temperature is higher than 20°C Second, make fruit.

Description

technical field [0001] The invention relates to a method for cultivating grapes, in particular to a method for cultivating grapes which are harvested twice a year and cultivated for secondary flowers. Background technique [0002] Grapes are one of the main fruits in our country. Conventional viticulture only bears fruit once a year and harvests once. Adopting the two-harvest cultivation technology of grapes in a year can realize grape cultivation and harvesting twice a year. It is a new technology developed in recent years. This technology not only meets the market demand, but also increases the income of fruit farmers. [0003] The existing two-harvest cultivation method for grapes a year has two modes, which are: [0004] (1) The two-generation co-cultivation mode in which the first and second fruits overlap and grow, that is, technical measures are taken at the young fruit stage of the first fruit, and the second flower is promoted again to form the second fruit; The ...

AI Technical Summary

Problems solved by technology

However, in the process of cultivating secondary flowers in this invention, the production management requirements are relatively fine; the flowering period of the secondary flowers is not uniform, which increases the cost of flower and fruit management;

Therefore, this two-harvest cultivation method is rarely used in production.
