Method for improving bird frame type low-trunk grape tree form

Abstract

The invention belongs to the technical field of grape cultivation facilities, and discloses a method for improving a grape bird frame type low-trunk tree form, which comprises the following steps of: improving a shed frame, adopting cement columns as frame columns, adopting a small-arch shed frame as the shed frame, and drawing 7 lines on a grape frame surface along the row direction; tree body shaping, wherein the overall tree shape is T-shaped in the current year of nursery stock planting, and young sprouts germinated in the growing period are bound to be in a flying bird frame shape; pruning management is conducted, the horizontal main vines bound to the first iron wires serve as bearing mother branches, and bud eyes and new shoots germinating below the horizontal main vines are all removed; the cultivation technology in different ripening periods comprises primary fruit management and delayed fruit management. By lowering the main vines and lengthening the growth distance of the vegetative branches, the method is more suitable for growth and cultivation management of'summer black seedless' delayed fruits compared with one-time fruits; by increasing the height of a fruiting zone, the fruits are lighter than the fruits which are damaged once, and the berry quality can be improved to a certain extent; trunks are determined in advance, tree shapes are obtained in advance, fruiting is carried out in advance, time and labor are saved, management is convenient, and the effect is fast.

Description

technical field [0001] The invention belongs to the technical field of grape cultivation facilities, and in particular relates to a method for improving the tree shape of a grape flying bird frame with low trunk. Background technique [0002] At present, grapes belong to the perennial deciduous vines of the family Vitaceae (Vitis) and have the characteristics of strong plant adaptability, high fruit yield, super-node differentiation of flower buds and multiple results in a year; Drying, juice making, medicine and health care and other purposes. With the rapid development of social economy and the improvement of living standards, people's demand for grapes is increasing day by day, and the area and output of grapes are constantly increasing. According to statistics, the global grape cultivation area reached 7.4 million hectares in 2018 (FAO), and my country's grape production reached 14.1954 million tons in 2019 (National Bureau of Statistics). [0003] In recent years, the...

Problems solved by technology

[0004] At present, there are many problems in the cultivation and management of grape ripening regulation: under the small trellis, the length of annual branches is not enough in the process of delaying fruit management (such as pruning to promote germination is Prune at the 6th to 9th node, and the fruiting zone is at the 9th to 12th node), the branches are easy to grow out of the scaffolding, which increases the incidence of diseases, making it difficult to produce high-quality delayed fruits; in some areas, delayed fruits are more commercially available than primary fruits (Normal fruit), especially the flowering rate is not high, the fruit is small, the yield is low, etc.

[0007] (1) In the current cultivation and management of grape ripening regulation, the length of annual branches is not enough in the small trellis and in the process of delayed fruit management (such as pruning to promote germination in the The 6th to 9th nodes are pruned, and the result band is at the 9th to 12th nodes), the branches are easy to grow out of the scaffolding, which increases the incidence of diseases, making it difficult to produce higher quality delayed consequences

[0008] (2) In the current cultivation and management of grape ripening regulation, the commerciality of delayed fruit in some areas is higher than that of primary fruit (normal fruit), especially the flowering rate is not high , small fruit, low yield, etc.

[0011] (2) The flower buds of the delayed fruit are poorly differentiated, and the fruit quality of the primary fruit is different, and it is not commercial
