Abstract

The invention provides a prediction model for predicting the density of a wood component by using moth damage information. The model is used to realize the rapid and accurate detection of the basic density of the wood, and provides a fast, accurate, simple and cheap method for the large-scale detection of the material property parameters of wood, so the genetic variation law of the material properties of the wood can be comprehensively known, the great potential of the wood is disclosed, accurate selection can be carried out, studies on the correlation among material property factors of the wood and among the material property factors, a growth factor and a form factor in China are enriched, and the process of genetic improvement of the wood is actually important. The establishment of thebasic density model of the moth damaged wood component overcomes the shortcomings, comprising long detection time, large human operating error and high cost, of conventional detection methods. The method has the advantages of no consumption of chemicals, reduction of harms of the chemicals to human bodies, typical nondestructive analysis measurement, good test reproducibility, high analysis efficiency and good result stability.

Description

technical field [0001] The invention relates to a method for predicting the density of wooden components, in particular to a method for predicting the density of wooden components by using moth information. Background technique [0002] At present, the determination method of wood density mainly adopts GB / T 1933-2009 wood density determination method, which is applicable to the determination of air-dry density, full-dry density and basic density of small unblemished wood samples. The basic density of wooden components is determined by the drainage method (that is, refer to GB / T 1933-2009 Timber Density Determination Method). When using this method to measure the density of wooden components, there are strict requirements on the sampling and preparation of samples. The measurement process has cumbersome steps, time-consuming, great damage to the sample, and large human error and low efficiency. shortcoming. Contents of the invention [0003] The technical problem to be so...
