Description

Portable fruit tree girdling device

Technical Field

The utility model belongs to the technical field of fruit tree circular cutting, and particularly relates to a portable fruit tree circular cutting device.

Background

The ring cutting technology is adopted in fruit tree production, and effects of controlling vigorous growth, protecting flowers and fruits, preventing and controlling fruit cracking and promoting flower bud formation can be achieved. The fruit trees are balanced, the yield is increased, and the economic benefit of the orchard is improved.

The fruit tree girdling function: 1. controlling the tree vigor: the tree is vigorous and prosperous, resulting in no or little blossoming and bearing. The ring cutting can prevent the photosynthetic products from being transported downwards, improve the nutrition level and carbon-nitrogen ratio of branches above the cutting day and promote the flower bud differentiation. 2. Flower and fruit retention and stabilization: the effect of improving the fruit setting rate is obvious. 3. And (3) fruit cracking reduction: when a large amount of rainfall or irrigation suddenly occurs after a long drought, the fruit cracking rate of some orchards or single plants can reach more than 50 percent, thereby reducing the yield and influencing the quality. Preventing fruit cracking, timely irrigating to maintain proper water content in soil, reasonably applying fertilizer, and timely girdling after long-term drought and raining, wherein girdling should be performed according to tree vigor and attention is proper. 4. And (3) promoting flower bud differentiation: the ring cutting technology is adopted to promote the transformation of leaf buds to flower buds, breed a large amount of high-quality flower buds, promote differentiation and improve the yield of fruit trees in the next year.

The applicable objects of fruit tree girdling are as follows:

the method is generally used for perennial fruit trees such as oranges, plums, pears, Chinese chestnuts, jujubes, waxberries and the like by girdling. And (4) selecting a growing bare-grown branch, a growing fruited or to-be-fruited sapling, a temporary tree in a planned close planting garden or a particularly strong branch group for girdling. The method is suitable for particularly vigorous woody and vine trees or strong young trees with sufficient fertilizer and water, high management level, thick green leaves, dark green leaves and the like, and is not suitable for girdling young trees, weak trees or fruit trees entering a high yield period. Otherwise, the tree vigor is easy to seriously decline and even die. The main trunk is not required to be girdled and girdled, each main branch is not required to be cut, banded and girdled, and tips of the branches are required to be reserved to deliver nutrients to roots, so that the nutritional requirement for normal growth of the roots is met.

The operation method of the fruit tree girdling comprises the following steps:

1. selecting morning and evening in sunny weather, selecting 5-10 cm thick main branch or bone branch, and cutting the girdling part with thin and sharp knife to ensure that the cortex is cut off and the depth is just equal to the xylem. Usually, the girdling is performed for 1-2 circles, and the depth reaches the xylem. 2. The girdling degree cuts are aligned and can not be staggered; cutting around the smooth part of the trunk to a depth of xylem with a blunt blade, wherein the width of the cut is about 1.5 mm, and after 1 hour, coating No. 2 cream with a width of 1 cm on the cut with a writing brush, and coating back and forth to make the medicine enter the cut. The high-temperature rainy weather can be used for 1-2 times. 3. The girdling can only reach the cortex deeply, does not damage the xylem, does not need to be too large, does not need to peel nearby the cut, and is not suitable for trees lack of fertilizer and lose pipes, weak tree vigor and high yield. Is only suitable for various fruit trees with vigorous growth and no fruit bearing or little fruit bearing.
