Eucommia, as a medicinal tree, is a tonic for the kidneys and antihypertensive medicine, farmers rely on the peeling of its skin to sell money, generally more than 1,000 pounds per mu, there are more than 20 years of age of eucommia, mu yield is close to 2,000 pounds, nearly doubling the earnings, only after peeling the skin of a time, but also need to wait three years before peeling again.

The 10-year old tree has a relatively high yield of eucommia bark, which can be partially peeled for the first time. Then every 4 to 5 years peeling is more appropriate, can maintain the normal growth potential of the tree, but also can effectively increase the production of dulcimer bark.

The peeling of eucommia, the traditional method of peeling is to cut down the tree and then peeling, eucommia to 20 to 30 years when the fastest growing, if cut down before this age, reduces the economic benefits; if you wait until the tree grows into the tree and then cut down the peeling, it is too late to gain the benefits of the time. since the 1970s, the study of the success of live tree ring peeling or peeling method, greatly improving the economic benefits.

The peeling time is roughly in early May to mid-July, due to different climatic conditions around the world, should be tested around the world, choose the best peeling period. According to the ring peeling test on the cultivated eucommia in Shenyang area, harvesting in May and June, the new skin formation is fast, the skin layer is uniform and the color is the same;?

Before winter, the new skin is 2 to 3 mm thick, peeling branches and leaves are still growing vigorously after wintering, the growth is normal after wintering, and the peeling parts have not seen frost damage; harvested in July, the new skin formation is slightly late, the new skin color is shallow and thin, and the growth of branches and leaves after peeling is not as good as the former.
