The latest course of girdling techniques and points for attention of Eucommia ulmoides

Eucommia ulmoides is a traditional Chinese medicine in China. It is the dry bark of Eucommia ulmoides. It has the effect of tonifying liver and kidney, strengthening muscles and bones and calming the fetus, so it has high economic value. While harvesting is to peel off the bark ring, now the use of ring peeling regeneration method, can increase the yield, let's take a look at the detailed introduction.

1. Peeling time

The best time to peel Eucommia ulmoides is when the temperature is about 25-30 and the air relative humidity is 70%-90%, that is, from May to June. During this period, the temperature was extremely high and stable, and there were more Rain Water and higher air humidity. The leaves of Eucommia ulmoides plants were all unfolded, so it was the best time for peeling.

2. Ring peeling method

First of all, it is necessary to make a horizontal cut in the branch of the trunk, which is vertically T-shaped. Pay attention to the length of the vertical cut, which can be cut horizontally to about 20 cm from the ground. To grasp the depth of the cut, you can cut off the phloem without damaging the xylem, then pick up the longitudinal seam with the tip of the knife, tear it with your hand, pry at the same time, and cut off the connected skin until the peeling is complete. In the process of peeling, do not use your hands or touch the peeled tree trunk, so as not to cause mechanical damage.

3. Protective measures

After girdling, protective measures should be taken to speed up the regeneration of new skin. generally, the air humidity after girdling is more than 80%, which is beneficial to the regeneration of new skin. After peeling, wrap the peeling part with a transparent film, the intersection of the film should be tied tightly so as not to be dried by the wind, the upper and lower ends should also be fastened with ropes, the upper part should be tighter and the lower part should be looser.

4. Points for attention

When girdling, it is appropriate to choose Eucommia ulmoides trees that have been growing for more than 10 years and fed. Trees with weak or poor growth should not be girdled, and the girdling length should not exceed 1 meter, so as to prevent the normal growth of plants from being inhibited. Ringpeeling should avoid rainy days, lest the wound can not heal for a long time and mildew, can not form new bark, affect the regeneration of bark, serious to the death of the tree, it is best to choose cloudy and rainless weather for girdling. Be careful not to damage the cambium of the trunk during girdling.
