Pruning method for fruit tree with inverted-V-shaped tree shape and bracket

Abstract

The invention provides a pruning method for a fruit tree with an inverted-V-shaped tree shape. The pruning method comprises the following steps: S1, selecting seedlings and determining the plant row spacing; S2, controlling growth intensity of branches on the trunk: pruning side branches, and properly retaining auxiliary branches which do not influence the growth of the central trunk; S3, mounting a bracket; and S4, carrying out tree shape cultivation: pruning and cultivating the fruit tree to obtain the fruit tree with the inverted V-shaped tree shape. The bearing branch groups and the vegetative branches are obviously separated, classified management is facilitated, the bearing branch groups are all located below the central trunk, and flower thinning, fruit thinning, bagging and harvesting are facilitated. The bearing branch groups are distributed on the two side frame surfaces, so that the consistency of the branch groups is improved, mechanical pruning of the fruit tree is facilitated, and therefore, the technical problem that the current fruit trees are difficult to mechanically prune is solved.

Description

technical field [0001] The invention belongs to the field of fruit tree planting and pruning, and in particular relates to a fruit tree pruning method and a bracket with an inverted V-shaped tree shape. Background technique [0002] my country is the largest apple producer in the world, with apple planting area and output accounting for more than 50% of the world. In 2020, my country's apple planting area will exceed 30 million mu, and the output will reach 41 million tons. The apple industry has played an important role in promoting my country's farmers' income and regional economic development. [0003] my country's apple cultivation model has gone through three stages: big crown and rare planting, arbor and stock close planting, and dwarf and close planting. Currently, arbor and stock close planting orchards still account for the majority, and new orchards mainly adopt the dwarf and close planting model. Dwarf and close planting orchards are the future development of appl...

AI Technical Summary

Problems solved by technology

[0004] The dense planting of the arbor anvil adopts the common type of arbor anvil and the tree shape of the free spindle shape. The dense planting of the arbor anvil is difficult to control the crown and promote flowering, resulting in a densely planted orchard with an arbor anvil, poor ventilation and light transmission, and low yield in the orchard. Low, serious pests and diseases, low level of mechanization, poor fruit quality and other shortcomings

Dwarf root stock and dense planting mostly adopt dwarf, semi-dwarf root stock and spindle-shaped small-crown tree shapes, which are technically difficult, time-consuming and labor-intensive in shaping, vegetative branches and fruiting branches intersect, low level of mechanization, and high investment in pesticides and fertilizers. , not easy to bag, low yield, large difference in fruit shape, low rate of high-quality fruit, etc.
