Problems solved by technology

[0004] Currently, the cultivation method of two harvests of grapes in a year mostly uses the auxiliary shoots at the top of the branches to carry out secondary fruiting. Due to the high position of the fruiting, a larger area is required for the shelf surface, which restricts the existing small shelf surface area. The orchard is cultivated with two harvests a year

Embodiment 1

[0023] The present embodiment provides a kind of high-yield cultivation method that utilizes the subshoots of the base to carry out two harvests of grapes a year, comprising the following steps:

[0024] (1) Winter pruning: Winter pruning is carried out to the mother branch of grape fruit at the beginning of January;

[0025] (2) Summer pruning: After the new shoots germinate in spring, fix the shoots according to the shoot spacing of 18cm, and 5 days before the remaining new shoots bloom, keep 2 leaves above the flower spikes; choose 1 below the 4th section The healthy auxiliary shoots are kept, and the remaining auxiliary shoots are removed in time, and the retained auxiliary shoots are topped when they grow to 4 leaves; only the top auxiliary shoots are kept above the fifth node, and the remaining auxiliary shoots are erased in time. When the shoot grows to 4 leaves, the heart is topped; when the auxiliary shoot germinates again after the topping, the following treatments a...

Embodiment 2

[0029] The present embodiment provides a kind of high-yield cultivation method that utilizes the subshoots of the base to carry out two harvests of grapes a year, comprising the following steps:

[0030] (1) Winter pruning: Winter pruning is carried out to the mother branch of grape fruit at the beginning of January;

[0031] (2) Summer pruning: After the new shoots germinate in spring, fix the shoots at a shoot spacing of 20 cm, and 6 days before the flowering of the remaining new shoots, keep 2 leaves above the flower spikes; select 2 leaves below the 4th section The healthy auxiliary shoots are kept, and the remaining auxiliary shoots are removed in time, and the retained auxiliary shoots are topped when they grow to 4 leaves; only the top auxiliary shoots are kept above the fifth node, and the remaining auxiliary shoots are erased in time. When the shoot grows to 5 leaves, the heart is topped; when the auxiliary shoot germinates again after the topping, the following treat...

Embodiment 3

[0035] The present embodiment provides a kind of high-yield cultivation method that utilizes the subshoots of the base to carry out two harvests of grapes a year, comprising the following steps:

[0036] (1) Winter pruning: Winter pruning is carried out to the mother branch of grape fruit at the beginning of January;

[0037](2) Summer pruning: After the new shoots germinate in spring, fix the shoots according to the shoot spacing of 22cm, and 7 days before the remaining new shoots bloom, keep 3 leaves above the flower spikes; select 2 leaves below the 4th section The healthy auxiliary shoots are kept, and the remaining auxiliary shoots are removed in time. The reserved auxiliary shoots are topped when they grow to 5 leaves; When the shoot grows to 5 leaves, the heart is topped; when the auxiliary shoot germinates again after the topping, the following treatments are carried out: a. If the garden is cultivated with a V-shaped frame, the heart is repeatedly picked when the auxi...

Abstract

The invention provides a high-yield cultivation method for harvesting grapes twice in one year by base sub-lateral shoots, and relates to the technical field of grape cultivation. The high-yield cultivation method includes the steps: (1) winter pruning; (2) summer pruning; (3) re-flowering facilitation; (4) other management. According to the method, the grapes are harvested twice in one year by cultivation, fruiting parts of secondary fruits can be reduced, nutrition backflow is promoted, ineffective growth is decreased, light energy is sufficiently used, management is facilitated, pruning wounds are increased, the germination number of winter fruits is increased, and the yield and benefits of the winter fruits of the grapes are improved.

Description

【Technical field】 [0001] The invention relates to the technical field of viticulture, in particular to a high-yield cultivation method for harvesting grapes twice a year by using auxiliary shoots at the base. 【Background technique】 [0002] Grape is one of the main fruits in our country. It is rich in various nutrients such as sugar, organic acid, protein and vitamins. It is a kind of fruit suitable for all ages. It is also the raw material for various beverages, such as wine. Grapes are also seasonal fruits. Generally speaking, the ripening period of fresh grape fruits in southern regions ends in mid-to-late August, and in northern regions in mid-to-late October. Therefore, there is a large supply of fresh grape fruits on the market from September to November, while in other regions During the month, the supply of fresh grapes is less. [0003] Conventional viticulture only bears one fruit a year and harvests once. In recent years, in order to adjust the market supply of ...
