A Cost-Effective Method for Pulling Branches of Apple Trees

Abstract

The invention discloses an economical and high-efficiency apple tree branching method, which comprises the following steps: (1) Concentrating on carrying out plastic bags to store soil, each bag containing 0.3-1 catties of soil, forming soil bags for use; (2) According to the age of the branches 1. The degree of thickness determines the hanging position of the branch, and the hanging position is wrapped with the described soil bag to pull the branches. The determination method of the hanging position and the soil bag is: annual or branches with a thickness of 0.7-1.0cm, the hanging position At a distance of 15-20cm from the base of the branch, the soil bag is 0.3-0.4 catties of soil; for biennial branches or branches with a thickness of 1.1-1.3 cm, the hanging part is at a distance of 30-35 cm from the base of the branch, and the soil bag is 0.5-0.6 catties of soil; three-year-old Or branches with a thickness of 1.4-1.6cm, the hanging part is 50-60cm away from the base of the branch, and the soil bag is filled with 0.9-1 catties of soil. The invention is easy to obtain materials, low in cost, the soil bag can be recycled and used for many times, easy to operate, saves time and labor, does not damage the branches, and is suitable for hanging and pulling the main branches, side branches and fruiting branches of various tree shapes in apple production and cultivation. Branches, wide adaptability.

Description

technical field [0001] The invention belongs to the technical field of fruit tree shaping, pruning and branch pulling, and in particular relates to an economical and efficient method for pulling branches of apple trees. Background technique [0002] During the growth of apple trees, in order to reduce the dominance of the top of the fruit tree and avoid a large amount of nutrients from being supplied to the branches and the tree body to affect the flower bud differentiation and fruit setting of the fruit tree, the fruit tree is usually pulled, bent, twisted, etc. The current methods of pulling branches for apple trees are mainly simple wooden sticks, poles and other support methods, ropes, plastic straps combined with wooden wedges for pulling branches, and using commercial angle-opening branch pullers for pulling branches. However, these methods for pulling branches have the following deficiencies Where: [0003] Simple wooden sticks, poles and other supporting methods are...

AI Technical Summary

Problems solved by technology

In the process of pulling branches, the size of the space between the tether and the branches is difficult to grasp. If the space is too large, the rope will easily slide on the branches, and the effect of pulling the branches is not ideal; if the space is too small, the rope will easily hinder the normal growth of the branches, causing the branches to suffer The subsidence of the cortex not only inhibits the growth of the front of the branch, promotes the growth of the rear, and the growth is disordered, but also breaks easily at the strangled part, especially when the branch bears heavy fruit, it is more likely to break, and the strangled branch has poor fruit bearing capacity.

[0005] Using the method of pulling branches with open-angle branch pullers, the use of open-angle branch pullers is expensive, with an average price of 0.5-1.5 yuan / piece. Generally, free spindle-shaped and improved spindle-shaped trees are 5-6 years old, and the number of branches per plant About 60 orchards planted with a density of 3×4 meters, 56 branches×60 = about 3360 pieces of branch pullers are needed, and the cost is 1680-5040 yuan. The cost is too high, and the adaptability of the branch pullers is relatively low. Narrow, only suitable for main branches that are 1-2 years old. For main branches that are more than 2 years old, because they are too large and thick, the angle straightener will not be able to open the corners. At the same time, the fruiting branches on the side branches and main branches will The support and pulling effect of the corner puller is not good, and it is easy to damage the branches
