왕대의 伐根周圍(根株周圍)와 胸高周圍와의 關係 = Relation between C.B.H. and Stump Circumference of Phylostachys reticulata Koch

국문 초록 (Abstract)

우리나라에서는 觀習的으로 竹結束의 편의상 胸高周圍와 伐根周圍를 같게 取扱하며, 더욱이 取捨方法如何에 따라 實際竹의 束數와 差가 많으므로 胸高周圍와 根株周圍와의 關係를 究明하여 이와 같은 不合理한 點을 是正코져 왕대 1024本에 對하여 調査測定한 結果를 要約하면 다음과 같다.
1. 왕대 1024本을 材料로 하여 伐根周圍로서 胸高周圍를 推定코저 본 調査를 實施했던 바 이 兩者間에는 直線的 關係가 있음이 認定되었다.
2. 一次式 X=a+bY로서 回歸式을 유도한 바 X=0.988+0.965Y와 같은 式을 유도하였고, γ=0.97992±0.00062이었다.
3. 이 回歸式을 使用하여 根株周圍로서 胸高周圍를 推定할 수 있는 關係表는 表 Ⅳ와 같다.

In Korea, binding-up of bamboo was usualy dealed with circumference breast height and stump circumference together. By the way, according to method of adoption and rejection, bundle of bamboo has a lot of differences.
So I find out the relation between circumference breast height and stump circumference, and in order to correct absurdity like these. I investigate and measured the follows in short.
1. In order to find out the means of estimating circumference breast height of cutting bamboo with the stump circumference, relationship between stump circumference and circumference breast height was investigated by employing 1,024 Phylostachys reticulata Koch as sample, and a linear relationship between those two has been recognized.
2. The regression equation led in linear equation, X=a+bY, was X=0.988+0.965Y and r=0.97992±0.00062.
3. With this regression epuation the related list which can estimate, as stump circumference, is (as the follow) Table Ⅳ.
