Apple tree shaping and pruning management technique

Abstract

The invention discloses an apple tree shaping and pruning management technique. Planting, main branch determination, pruning and shaping, and a series of fertilizer applying techniques are used, so that apple trees can bloom and bear fruits in two years, the per mu yield of three-year-old apple trees can achieve 1000 kilograms, and the per mu yield of the five-year-old apple trees can achieve 5000-6000 kilograms. The pruning method is simple to operate and easy in popularization.

Description

Technical field: [0001] The invention relates to an apple tree shaping and pruning management technology Background technique: [0002] Since the early 1990s, my country's main apple production areas and apple technology research institutes have transformed from the former Soviet Union's main tree shape with delayed layer delay to the Western European free spindle shape as the main tree shape. [0003] Key points of free spindle shaping trimming: [0004] Before planting, carry out deep plowing and leveling on the land, the live soil layer reaches 40 cm deep, and keep drainage ditches. When planting, first dig a square pit with a length and width of 40 cm and a depth of 20 cm, apply a small amount of bio-organic fertilizer and potassium sulfate compound fertilizer into the pit and mix evenly, fill a small amount of soil, and then place a square pit with a height of more than 1.2 meters. The seedlings are planted in the pit, and the soil is buried and compacted (the spacing...

Problems solved by technology

To sum up the above, although the free spindle pruning method can result in early results and obtain early high yields, it also has the following disadvantages: due to the need to carve buds on both sides of the central trunk and main branches, the branches are pulled back in summer, and the opening angles of the branches in spring and autumn are Time-consuming and labor-intensive, large investment

[0009] At the same time, if the angle of free spindle-shaped branches is too large (80-90 degrees), it will easily cause the dorsal advantage, resulting in vigorous growth of branches, consumption of a large amount of nutrients, difficulty in forming flower buds, and deterioration of light conditions.
