Economical and efficient apple tree branch stretching method

Abstract

The invention discloses an economical and efficient apple tree branch stretching method. The method includes the following steps of firstly, concentratedly containing soil with plastic bags, wherein 0.3-1 g of soil is contained in each bag, and the soil containing bags are formed for use; secondly, determining the hanging parts of branches according to the ages and thicknesses of the branches, andhanging the soil containing bags on the hanging parts for branch stretching, wherein according to the method of determining the hanging parts and the soil containing bags, the hanging parts of the branches which are one year old or have the thickness of 0.7-1.0 cm are 15-20 cm above base parts of the branches, and each soil containing bag contains 0.3-0.4 g of soil; the hanging parts of the branches which are two years old or have the thickness of 1.1-1.3 cm are 30-35 cm above the base parts of the branches, and each soil containing bag contains 0.5-0.6 g of soil; the hanging parts of the branches which are three years old or have the thickness of 1.4-1.6 cm are 50-60 cm above the base parts of the branches, and each soil containing bag contains 0.9-1 g of soil. Materials are easy to use,cost is low, the soil containing bags can be recycled multiple times, operation is simple and convenient, time and labor are saved, no branches are injured, and the method is suitable for hanging andbranch stretching of main branches, side branches and fruiting branch groups of fruit producing and culturing trees of various shapes and high in 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
