Embodiment

[0060] (1) adopt the forest compass, combine the triangular property and the mathematical principle to measure the tree height h of Magnolia officinalis living trees, the specific measurement method is shown in the paper "Using the forest compass to measure the tree height" published by Lin Feng et al.;

[0061] (2) Climb to the center of the trunk to measure the diameter of the trunk with the help of the climbing board Then use the bark sampling mold to take a piece of bark at the center of the trunk, and use a digital display vernier caliper to measure the thickness of the bark, that is, the thickness of the bark at the center of the trunk t 中央 ;

[0062] (3) Adopt the bark sampling mold to get a piece of bark at the DBH place of the living tree of Magnolia officinalis, measure the fresh weight FW, length l, width w and thickness t of this piece of bark 胸径 ;

[0063] The specific measurement method is: the bark sampling mold is erected at the DBH, and the inner frame edge...

Abstract

The invention discloses a method for measuring and calculating the bark yield of Magnolia officinalis, comprising: collecting information on the height of the Magnolia officinalis, the central diameter of the trunk and the thickness of the bark at the center of the trunk; Take a piece of bark, according to the obtained bark information, calculate the density of the bark of Magnolia officinalis; bark yield. The method does not limit the age group and the measurement time, has high measurement accuracy, and effectively solves the problem that the bark yield value of Magnolia officinalis is difficult to obtain. It is of great reference significance to carry out the breeding and asset evaluation of Hopu improved varieties.

Description

technical field [0001] The invention relates to the field of forest resource investigation, in particular to a method for measuring and calculating the bark yield of Magnolia officinalis living trees. Background technique [0002] Magnolia officinalis ( officinalis (Rehder et E.H.Wilson) N.H.Xia et C.Y.Wu) is a deciduous tree of the genus Magnolia in the family Magnoliaceae. It has the effects of drying dampness and eliminating phlegm, lowering Qi and eliminating mites. It is a unique traditional Chinese medicinal material in my country and belongs to the National II Class-level key protected tree species and Class-II protected Chinese herbal medicines. The medicinal Magnolia officinalis mainly includes Magnolia officinalis Rehd.et Wils.subsp.officinalis (Magnolia officinalis Rehd.et Wils.subsp.officinalis) and Magnolia officinalis Rehd.et Wils.subsp.biloba (Rehd.et Wils.) Law); the most obvious difference between Magnolia officinalis and Magnolia officinalis is whether the...
