Abstract

The invention discloses a molecular identification method of a tree species of a wood and a material of each part of a wood product. The method comprises: if it is judged that all of a cross section, a longitudinal section, and a peeled section of a to-be-identified wood or a material of a part of a wood product achieve a set smoothness standard, obtaining microscopic characteristic information of the wood or the material of the part of the wood product at a cellular level and a molecular level from the cross section, the longitudinal section, and the peeled section; and comparing the obtained microscopic characteristic information at a cellular level and a molecular level with microscopic characteristic information of known tree species at a cellular level and a molecular level to determine the tree species of the wood or the material of the part of the wood product. Based on the comparison of microscopic characteristic information at a cellular level of the to-be-identified wood or the material of the part of the wood product with that of known tree species, a comparison method of microscopic characteristic information at a molecular level is added, so that the tree species of the wood or the material of each part of the wood product can be accurately identified.

Description

technical field

[0001] The invention relates to the field of wood identification, in particular to a method for identifying tree species used for wood and parts of wood products. Background technique

[0002] In recent years, the consumption, trading volume and import volume of wood and wood products in my country are relatively huge. There is a large price difference between wood of different tree species, or wood product parts made of wood of different tree species. In order to ensure that consumers can buy genuine wood and wood products, it is necessary to check tree species are identified.

[0003] At present, a kind of identification method of the tree species of timber used in various parts of wood and wood products comprises: cutting out a small sample from the wood to be identified or the materials used in various parts of wood products; softening the sample; softening the softened sample After slicing and taking pictures, make temporary or permanent sliced ​​speci...

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0020] In the technical solution of the present invention, for the wood or wood product parts to be identified, if it is determined that the surface reaches the set smoothness standard at a higher magnification by using a portable microscopic device, then the magnification can be determined at the set magnification. Next, obtain the molecular-level microscopic feature information of its surface; and compare it with the molecular-level microscopic feature informati...
