Eucommia girdling and processing technology

Eucommia is the dry skin of the Eucommia plant Eucommia. The famous medicinal materials for our country's specialties have been cultivated for nearly a thousand years. The body of Eucommia ulmoides is a treasure. Eucommia ulmoides not only has liver and kidney, strong bones and muscles, and does a good job of tocolysis, but also the bark can be used to extract eucommia rubber. Wood is a superior material for making high-end furniture. Eucommia ulmoides leaves is a good animal feeding additive. Very high. Eucommia can not be stripped 6-10 years after it is cultivated in general. The author did not cut down and peel the Eucommia tree when he was retired to establish Duzhong Forest Farm, and he adopted girdling regeneration technology to increase the yield of Eucommia bark. The introduction is as follows:

First, girdling technology

When duodenum breast diameter is more than 5 cm, peeling is performed. The best peeling time is from May to June in Jiangnan and from June to July in Jiangbei; the roots of Eucommia ulmoides are peeled off after cloudy or cloudy or rainy days. Cross a circle at a centimeter, deep to the xylem, then cut it again from the ground at a distance of 10 cm. Then cut a knife between the upper and lower blades to reach a layer of depth, taking care not to damage the cells of the young xylem on the surface of the xylem. Gently peel off the bark and spray Eucommia "Zengpi Ling" or Eucommia "promoting agent" on the xylem of the tree bark. (Available at Plant Protection Stations.) The preparation is sprayed at a certain concentration on the nude body of the Eucommia zombie. After 30 days, the neoplastic cells grow well and the contamination rate is almost zero. Its production and utilization are convenient, the growth promoting agent has a low cost, and the neonatal cell layer is rich. When circling the Eucommia ulmoides should avoid sun exposure and prevent the pollution of nearby pesticides, and do not touch the hand or other mechanical hit xylem.

When the eucommia tree was peeled and sprayed with Eucommia cervix or a growth promoting agent, the nude body was bandaged with a mulch, the upper bandage was tight and the lower part was slightly loose; the mulching film was peeled off after 40-45 days. With the above circumcision (skin) regeneration technology, the survival rate after peeling can reach 100%, and the second girdling can be performed 1-2 years earlier than the general peeling technique.

Second, processing technology

The eucommia bark peeled off was scalded with boiling water and placed on the bottom of the straw so that the eucommia ulmoides peels closely overlapped with each other. The mulberry bark was overlaid with wood, and the stones were pressed flat. Then, they were covered with straw to make them “sweat”. After 5-6 days, take out the middle of the inspection, if the inside of the bark has been purple or dark brown, you can take out the sun, scrape off the rough skin, trim the side skin according to the specifications, bale or process and cut into the Eucommia silk and then Pan fried, exquisite packaging (250 grams a box) for sale, the higher the price.
