Problems solved by technology

However, these techniques will cause wounds to the apple tree body. The wound is the main source of fruit tree rot, and it cannot solve the problem of light in the orchard for a long time. After a few years, the orchard will be closed again, and it will have to be remodeled again, causing a lot of damage. renovation cost

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0022] The method for transforming closed apple orchards provided by the invention is aimed at the transformation of closed apple orchards with tree ages over 10 years old, orchard coverage above 80%, and light transmittance under tree canopies below 20%.

[0023] Furthermore, these orchards also have the following characteristics: orchards with high density, in which there is basic handover between rows (the working belt is less than 1 meter), severe handover between plants (the length of branch handover exceeds 30 cm), and poor light conditions in the orchard (the canopy canopy is transparent). light rate below 20%), field operations are difficult. And there is almost no yield in the lower part of the canopy, and the leaf area index exceeds 3.5.

[0024] In addition, in terms of canopy str...

Abstract

The invention discloses a crown-closure apple orchard improvement method which mainly based on uprooting combined with tree form modification. Uprooting is a most fundamental, most thorough and most effective technological approach for crown-closure apple orchard improvement and mainly functions in removal of unnecessary plants, adjustment of planting spacing, reduction of planting density and opening of light paths and operation passages of orchards to solve the problem of crown closure of the orchards. According to tree ages, planting spacing and crown closure degrees of the orchards, two modes including 'one-time uprooting' and 'delayed uprooting' can be adopted for the crown-closure orchards. Sufficient work space and sufficient growth space for fruit trees are reserved after uprooting, the fruit trees are trimmed into proper shapes, preferentially heart shapes, by taking measures of lifting, topping, opening, branch pulling and the like, and accordingly fruit quality can be improved, and overall efficiency of the orchards can be improved.

Description

technical field [0001] The invention belongs to the technical field of apple cultivation, and relates to a method for transforming an apple canopy garden. Background technique [0002] At present, the area of ​​apples in my country has reached 30.73 million mu, of which 70% are apple orchards planted after the 1990s. There are common problems such as excessive planting density of arbor anvils, joints between rows, crossing between plants, poor ventilation and light transmission in the group; middle anvils in short anvil orchards All buried in the soil, dwarfing into arborization. Improper selection of tree shape in densely planted gardens, non-standard shaping techniques, too high and too large tree crowns, poor individual ventilation and light transmission; unreasonable tree structure, uncoordinated growth, low trunk, thin middle trunk, and no obvious advantage of the central leadership ; Branches or branch groups are multiaxially extended, crowns are large, and fruiting pa...
