The tree diameter at breast height and crown length can be used to predict the size and location of mean knot diameter in a whorl.A linear mixed model expressed as function of tree and knot variables such as HK、RKD、KD and DBH was used to predict sound knot length,and a log-linear mixed model using RKD and DBH as variables was used to describe loose knot length.4.A knot has four development phases:from the birth of a branch to its growth cessation,from growth cessation to death,form death to occlusion and form birth to occlusion.The numbers of annual rings in four periods,as well as the stem width of respective zones were used as dependent variables predicted by models expressed as function of tree variables and knot attributes.5.Using the data of diameter out side bark of 15 relative heights along the step,the best taper equation for Larix olgensis was established.

节子平均直径可以用以胸径，冠幅和节子高度为参数的舒马克生长方程来预测，用树木胸径和冠长可对每轮节子平均直径的最大值及位置进行预测；健全节长度可用以节子着生高度、相对直径、节子直径以及树木胸径为参数的线性混合模型来预测，疏松节长度采用节子相对直径和胸径为自变量的可转化为线性模型的自然对数模型来预测；4、节子有四个生长发育时期：从枝条形成到生长停止BC从生长停止到死亡(CD从死亡到包藏DO从形成到包藏

Controlled by the computer, the device can transport a sample to be subjected to parameter extraction to the electrical rotation stage through the pipeline system, the CCD imaging system takes the plant image at a single angle, then the images are subjected to image segmentation by the computer, the projection plant height at the angle can be obtained after subjecting the divided binary images to skeleton extraction and leaf path searching, and finally the maximal value of the projection plant heights at all angles is calculated as the plant height.

本发明涉及植物株高自动测量装置及测量方法，本装置包括流水线系统、可见光CCD成像系统、电动旋转台、旋转台控制器、计算机、图像采集卡，电动旋转台依次与旋转台控制器和计算机相连，可见光CCD成像系统依次与图像采集卡和计算机相连，本发明由计算机控制，采用流水线系统，将待提取参数的样品送上电动旋转台，由CCD成像系统拍摄单个角度下的植株图像，由计算机将所得图像进行图像分割，从分割后二值图像经过骨架提取和叶片路径搜索可得到该角度下投影株高，最后求出所有角度下投影株高的最大值作为植株的高度。
