Problems solved by technology

However, this method requires a lot of labor, time-consuming and labor-intensive, and the cost is high. Especially in today's increasingly expensive labor force, its promotion is becoming more and more difficult, and it will also have an impact on the surrounding environment. Network coverage technology becomes very urgent and necessary

Embodiment 1

[0009] Eight bayberry trees of 'Fugong No. 1' were used as test trees, all of which were 12 years old, with a height of 3.3-3.6 meters and a crown diameter of 5.5-6.1 meters. They were pruned for the first time in October 2012. Select 5 more robust branches as the branches supporting the insect-proof net, cut off the side branches and pull the branches so that the angle between them and the horizontal plane is kept at 70°, and at the same time remove the large branches in the inner chamber, and dwarf the entire tree crown Retraction pruning, keep the selected 5 branches about 80 cm above the crown. Prune off the newly grown side branches in the next year to ensure the nutrient supply for the growth of the supporting branches, and perform appropriate retraction pruning according to the growth speed and quality of the supporting branches to ensure that the supporting branches are about 80 cm above the crown.

Embodiment 2

[0013] Four 'Ruansi Anhaibian' red bayberry trees were used as test trees, all of which were 10 years old, with a height of 3.1-3.4 meters and a crown diameter of 4.9-5.5 meters. Select 7 branches with stronger growth as the branches supporting the insect net, cut off the side branches and pull the branches to keep the angle between them and the horizontal plane at 60°, and at the same time remove the large branches in the inner chamber and dwarf the entire tree Retraction pruning, keep the selected 7 branches about 60 cm above the canopy. Prune off the newly grown side branches in the next year to ensure the nutrient supply to support the growth of the branches, and perform appropriate retraction pruning according to the growth speed and quality of the supporting branches to ensure that the supporting branches are about 60 cm above the crown.

[0014] Cost analysis: The pruning and shaping of the 4 test trees can be completed by one worker in one day. The daily salary of the ...

Embodiment 3

[0017] Four 'Ruansi Anhaibian' red bayberry trees were used as test trees, all of which were 12 years old, with a height of 3.2-3.5 meters and a crown diameter of 5.2-5.8 meters. Select 6 more robust branches as the branches supporting the insect-proof net, cut off the side branches and pull the branches so that the angle between them and the horizontal plane is kept at 50°, and at the same time remove the large branches in the inner chamber and dwarf the entire tree Retraction pruning, keep the selected 6 branches about 70 cm above the crown. Prune off the newly grown side branches in the next year to ensure the nutrient supply for the growth of the supporting branches, and perform appropriate retraction pruning according to the growth speed and quality of the supporting branches to ensure that the supporting branches are about 70 cm above the crown.

Abstract

The invention discloses an arbutus tree pruning method facilitating insect net suspension. According to the invention, robust supporting branches are directly cultivated on the periphery of an arbutus tree; inner large branches are thinned; and an entire crown is subjected to dwarfing retraction cutting. Therefore, a natural support formed by arbutus tree large branches is used as a support frame for suspending the insect screen. The insect screen can be suspended on the arbutus plant, such that damages caused by fruit tree pests such as fruit flies can be prevented. The implementation method of the invention is simple, and cost is low. With the method, insect net suspension time is short, and efficiency is high. The harm of pests to arbutus fresh fruits can be substantially reduced, and fruit farmer funding can be substantially reduced. The method has significant economic benefit, and is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a bayberry pruning method which is convenient for hanging insect-proof nets. Background technique [0002] Red bayberry fresh fruit is sweet and sour, and is very popular among consumers. However, fruit flies are vulnerable to damage during the fruit growth process, which can easily lead to a decline in fruit quality. During production, fruit growers usually use spraying drugs for prevention and control. Although some effects can be obtained, it also leaves more pesticide residues in bayberry fruits, causing food safety hazards. In recent years, it has also been proposed to cover the bayberry trees with insect-proof nets to prevent insect damage, that is, to build supports with moso bamboo or steel frames around the bayberry trees, and to cover more than 40 orders of insect-proof nets on the bayberry fruit trees 40 to 50 days before harvesting. . Howe...
