The so-called fruit tree molting is the method of removing bark from the base of the trunk or main branch and exposing the smooth xylem to promote the formation of new bark during the vigorous activity of the fruit tree formation. The role of molting is to prevent and treat diseases and pests of fruit trees, and promote the high yield of fruit trees. The following describes the methods and functions of fruit tree molting.
First, the method and period of fur
1. Most of the methods are from the top down, first cut off the bark at the base of the trunk or main branch, or dig a hole to the xylem first, then insert a wedge in the hole, cut the bark horizontally, cut off both hands Live the broken skin and tear it, you can tear it directly into the root and neck of the trunk. The bark had yellowish-white coloration just after it had fallen off, and soon the color became darker. It turned reddish brown after 1 week and the new skin had basically formed. After the winter, the new skin turned gray, and the color of the newly formed bark no longer changes, but only grows thick. From the results of the investigation of pear tree moltings at different times, the new skin thickness was 0.7 mm after 40 days of skinning, 0.8 mm 45 days thick, and 1 mm thick 60 days; the new skin was 1.6 mm thick after 1 year of molting. The bark that is reformed after molting is relatively smooth. About 10 years later, with the thickening of the new skin, cracks begin to appear, and thin skins appear.
Fruit trees can be mowed several times in their lifetime. We saw the pears that had been peeled in 1990 at Tianguan Sungou Orchard. In 2005, we once again skinned and the new skin formed again. The growth and development of the trees is the same as other trees. In 2005, we conducted three molting tests on apple saplings and old pear trees in the orchard of Beijiao Village, Dinghe Town, on June 24th, June 28th, and July 13th respectively. The effect is also very encouraging. satisfaction.
2. Sungou orchards generally carry out molting on the second day after entering the mountain. In the past two to three years, many fruit farmers came to visit and study and required demonstrations. In this way, from Mang species, from the summer solstice to the great summer, fruit tree moltings were carried out, and none of the results were fatal. Of course, the suitable period of molting in different regions and conditions was different.
Second, the role of fur
1. Prevention and control of pests and diseases When fruit trees are rotted and dry rot are harmed, scrapings often leave diseases of varying sizes, which are generally difficult to heal. Because they are exposed all year round, the xylem decays, causing nutrients and moisture to be blocked, resulting in trees. The weaker, lower production, shorter life expectancy. After molting, it can be pre-preserved so that the bark is updated. For example, in 1985, an old pear tree in the moltings had three original tree holes and the two tree holes after healing had healed. The reconstituted bark cells after molting are dense and tough, not only can prevent the invasion of bacteria, but also enhance the disease resistance of fruit trees.
Mink skin can also be larvae of some branch pests (such as small gimidines, small perches, etc.) to carry out manual killing, and to play a good role in the treatment of pests. After the fruit trees pass through the molting, the bark is smooth, free from cracks and flaking, so that the wintering pests have no hiding place.
2. To promote the formation of flower buds and ensure that the fruit tree has the same effect as ring peeling in the high-yield fruit tree, which is conducive to the differentiation and formation of flower buds and lays a good foundation for the next year's high yield. For example, there is a pear tree in Beijiao Village, Dinghe Town, Xixia County. Although it grows vigorously, it does not produce results year after year. After being guided by humans, it was smashed in 1995. In 1996, the tree tended to ease, resulting in more results. There are similar situations elsewhere. Our experimental team carried out the molting of apple trees and pear trees. After processing, the leaves were dark green and the leaves were thick and brittle. Their dry matter weight was higher than that of the control trees.
3. Make the young trees advance. The saplings generally have more nutritious growth and are less likely to form flower buds. The use of a tanned skin method can properly suppress leggy and promote the early formation of flower buds. The schedule is a survey of relevant conditions of the 9-year-old red star apple in the orchard orchard.
4. To improve the quality of fruit The fruit trees accumulated a lot of nutrients after molting, in addition to favoring flower bud differentiation, it also had a good effect on fruit growth. According to Sungou Orchard management staff, compared with the control, Fructus trichocarpa fruit has neat size, bright coloration, and thin skin, such as increased fruit after hawthorn; the content of soluble solids measured by refractometer is higher than that of Fir tree. The control was slightly higher; the fruit coloring was not significantly different from the control.
Third, pay attention to matters
1. Don't touch mucus while molting During molting, care must be taken to protect the mucus in the xylem. Once the mucus is knocked off, new bark cannot be formed and the tree will be strangled.
2. Avoid rainy days. In northern China, before and after the rain falls in rainy season, after raining, the mucous membranes will shower out, or the mucus will not dry after a long period of time. It is easy to mold and rotten, new skin. Nor can it be formed: Therefore, do not mingle in rainy days.
3. After scabs to avoid the sun exposure and the spraying season, the temperature is higher, and the young tissue after the skin is exposed to the sun. The new skin is not well formed. Therefore, it is necessary to shade the saplings or incomplete trees. In addition, high-concentration pesticides cannot be sprayed just after molting. Otherwise, young tissues will be injured, resulting in poor molting.
4. When the tree vigor is weakened, it is not possible to molt the skin to weaken the tree vigor. When the tree vigor is too weak, the molting effect is not good. After the clams, the new skin becomes thicker and slower, and the tree vigor is even weaker.
IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor.
