Staggered-layer cultivation method for prunus avium and four-layer arc-shaped shed frame used in method

Abstract

The invention discloses a staggered-layer cultivation method for prunus avium and a four-layer arc-shaped shed frame used in the method. The staggered-layer cultivation method comprises the steps thatthe four-layer shed frame is set up in a field planting cherry orchard, odd-layer trees and even-layer trees are arranged in the same row at intervals, the main branches of the odd-layer trees grow on frame surfaces of shed frame bodies in the first layer and the third layer, the main branches of adjacent even-layer trees grow on a frame surfaces of shed frame bodies in the second layer and the fourth layer, and the odd-layer trees and the even-layer trees are alternately planted in staggered layers. The four-layer shed frame comprises upright columns 1 which are arranged vertically and horizontally, the two or more upright columns 1 are arranged into one row and fixedly buried, the upright columns 1 are each provided with four layers of arc-shaped cross arms 2, and the arc-shaped cross arms, in the same layer, on each row of upright columns 1 are connected through a pull rope into a shed frame surface. According to the cultivation method, staggered-layer cultivation is adopted, the tree structure is simpler and more convenient to manage, and production is early and stable. The four-layer arc-shaped shed frame is firm in structure and simple and flexible in building method, the management work spacer of flowers and fruits in the orchard can be controlled, and the orchard management cost is helped to be reduced.

Description

Technical field [0001] The invention relates to a sweet cherry cultivation technology, in particular to a sweet cherry staggered cultivation method with simple operation, premature and stable yield, and a four-layer arc-shaped shelf adopted by the method. Background technique [0002] The hedgerow cultivation of sweet cherry is an advanced cultivation technique that emerged in developed countries in the 1980s. It adopts a new low-density cultivation mode with narrow row spacing, large plant spacing, and fence-like frame support. The advantages of the fence-style tree are: fast forming, high planting density, early high yield; suitable for small-scale mechanized management, which can greatly reduce labor costs; simple tree structure, and all standard trim sizes are quantified. However, each tree needs to cultivate a four-layer crown for each tree. The crown structure is difficult to cultivate, and the balance of the tree vigor is difficult to control in the later stage. The low l...

Problems solved by technology

However, for the hedge-shaped tree shape, each tree needs to be cultivated with four layers of canopy. It is difficult to cultivate the crown structure, and it is difficult to control the balance of tree potential in the later stage; the land utilization rate is low, the investment in facilities is large, and the output is low. These problems lead to the promotion of the hedge-shaped tree shape. limit
