Method for improving yield of amur corktree bark

Abstract

The invention relates to a method for improving yield of amur corktree barks and belongs to the technical field of improvement of yield of barks of trees with the barks useful. The method comprises the following steps: selecting healthy amur corktree plants free from plant diseases and insect pests, girdling trunks, then binding up the profile with a plastic thin film after the bark is peeled, unbinding the plastic thin film after new bark is grown, removing branches sprouted at the base, and girdling the trunks, which are at least 10cm above the ground base and at least 10cm below trunk bifurcations, in sections, wherein peeling length of each section is 80-100cm, and a bark ring which is 8-10cm long is kept between two adjacent sections; and spraying a new bark regeneration agent to the profiles after the girdling and before binding. The method provided by the invention has the advantages that the barks are peeled in sections, and the new bark regeneration agent is smeared after the barks are peeled and used for growth of the new bark of amur corktree, so that on one hand, survival rate is improved and reaches more than or equal to 80%, on the other hand, new bark growth can be promoted after the amur corktree is peeled, regeneration time is shortened, thickness of the new bark can basically reach the thickness of an old bark, and sustainable regeneration and utilization of the amur corktree are realized.

Description

technical field [0001] The invention belongs to the technical field of increasing the bark output of bark trees, and relates to a method for increasing the bark output of amur bark. This technology adopts segmental peeling, and after peeling, apply new skin rejuvenation agent, which is mainly used for the growth of new bark of Phellodendron amurense. On the one hand, the survival rate is increased, reaching more than 80%. On the other hand, it can promote the growth of new bark after peeling and shorten the regeneration time. After 2-3 years, the thickness of the new bark can basically reach the thickness of the old bark, realizing the sustainable regeneration and utilization of amur bark. . Background technique [0002] Phellodendron amurense is a deciduous tree with a height of 10-15 meters and a diameter at breast height of more than 50 centimeters. The bark is light gray or taupe, deeply fissured, the cork layer is thick and soft, the inner bark is yellow, and the tast...

Problems solved by technology

However, if no special treatment is taken after peeling, the regeneration speed of the new skin is slow, and it often takes 4 or 5 years before the skin can be peeled again, and some even fail to regenerate the new skin; in addition, the content of active substances in the new skin is low, resulting in poor product quality

[0005] Application number is that the Chinese patent of 200710050755.2 discloses a kind of Cortex cork trunk large-area peeling and the method that makes it regenerate new bark, and it adopts trunk large-area integral peeling, and after peeling, spray growth agent and fungicide, although this method has certain effect, to a certain extent shortened the new skin regeneration time of Phellodendron cork, but its survival rate was low
