How to harvest the leaves of Eucommia ulmoides? Please introduce the method of Eucommia ulmoides bark leaves can be harvested with reference to the following methods: 1. The bark of Eucommia ulmoides trees planted for 10-15 years can be harvested for medicine. There are two ways to peel skin. (1) felling and peeling method, also known as total peeling method. The bark is easy to peel when the sap begins to flow from April to May every year. When peeling, first cut 1 knife along the trunk ring from about 20 cm at the base of the trunk, cut 1 knife every 80 cm ring on it, cut 1 knife longitudinally between the two rings, peel off the bark after cutting, and cut down the tree after peeling the base. continue to peel off the bark on the stem and branches, and the unsuitable length can be used for crushing bark. After cutting, the stump can still sprout and renew, because the root system is larger, the absorption capacity is strong, and the growth rate of sprouting strip is fast, so one sprouting strip is selected, and 7 Mel can be cut and peeled after 8 years.

When cutting longitudinally, it is necessary to enter the knife accurately and the depth should not hurt the xylem. After peeling, the bark will not be removed temporarily, and the bark will be taken for processing when the new bark grows. 2.
