Method for scalping large area of phellodendron amurense trunk and regenerating new skin

Abstract

The invention discloses a large area barking and bark regrowth method of trunk of phellodendron which deals with large area barking of the trunk and corresponding treatment for the phellodendron with the age of 3 to 15 years and vigorous growth in the local condition with temperature of 15-30 DEG C. The method essentially comprises the following steps: fertilizing before barking, barking, spraying barking growth promoter and fungicides, packing with plastic films, and unpacking and germination removal of the trunk after barking, etc. The method has no need to carry out barking after a phellodendron plant is cut down and new bark can grow in a short time after barking, with the survival rate of above 65 percent and re-barking after three years; the content of berberine which is the main active ingredient has no significant difference between reborn bark and original bark. Moreover, the method can not only change the conventional method of harvesting phellodendron bark which is killingthe goose that lays the golden egg so as to realize sustainable utilization of phellodendron resources, but also improve the productivity of phellodendron, having good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of peeling and regenerating new bark of Chinese medicinal materials used in woody bark, and particularly relates to a method for peeling and regenerating new bark of cork trunks in large areas.

One of them, so it is also called "Chuan Phellodendron". [0004...

AI Technical Summary

Problems solved by technology

This method has been used so far for hundreds of years, but it is obviously a harvesting method of killing chickens and taking eggs. It mainly has the following obvious shortcomings: the tree will be cut down and then peeled, that is, the cork will be replanted after the cut, and the growth of the cortex The cycle is long, generally more than 10 can be used. Therefore, the productivity of cork cypress is not high, and the speed of resource cultivation is far behind the speed of felling and utilization, which will also cause adverse effects on the ecological environment.
