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.

Embodiment 1

[0033] The test carried out the practical application of the method of the present invention in 2020 in the ×× adult Xiahei vineyard of Jujiangtang Village Committee, Lianhua Town, Gongcheng County, Guilin City, Guangxi.

[0034] The test area is 3 mu, the planting distance is 1.2 meters, the row spacing is 2.3 meters, and 241 plants are planted per mu; rain shelter cultivation, the rain shelter is 2 meters high and 1.8 meters wide. V-shaped off-frame plastic pruning is adopted, and the shoots are fixed according to the shoot spacing of 20cm after germination in spring, with an average of 2300 shoots per mu.

[0035] The test is established in 2 sub-districts, and the A test area adopts the method of the present invention to cultivate secondary flowers, with 2.8 mu of test area and 675 strains. In the B test area, the existing conventional two-generation and different hall model is used to cultivate secondary flowers with two harvests a year, with a test area of ​​0.2 mu and 4...

Abstract

The invention discloses a method for cultivating secondary flowers for harvesting grapes twice a year, and belongs to the technical field of grape cultivation. According to the method, fruiting branches in the current year and vegetative branches are uniformly retracted and trimmed to the eighth node 5-10 days after harvesting of primary-cropping fruits, and the secondary flowers are formed through recultured new shoots, so that the flowering branch rate is high, the flowering period is tidy, and high yield is guaranteed; the growth space of the branches and leaves is increased, and productionof high-quality secondary-cropping fruits is facilitated; and operation and management are simple and convenient, labor is saved, and production benefits can be improved. The method is suitable for producing the secondary-cropping fruits by adopting a two-generation different-hall mode for early-maturing varieties in areas with annual average temperature lower than 20 DEG C, and is also suitablefor producing the secondary-cropping fruits by adopting the two-generation different-hall mode for the early-maturing varieties, medium-maturing varieties and late-maturing varieties in areas with theannual average temperature higher than 20 DEG C.

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 ...
