本文研究了马尾松高、低产脂类型产脂量、产脂力和轴向树脂道的关系。初步结果认为:1.高、低产脂类型的产脂量和产脂力相差很大,树脂道面积、数量、直径也有差别;2.采脂割面下沿木质部的树脂道面积、直径与产脂力之间相关密切,相关系数分别为γ=0.629和γ=0.641;3.根据计算产脂力经验公式,测定树脂道直径或面积,可求出相应的产脂力,作为鉴定高、低产脂类型的估测依据。
In this paper, the relationship between lipid mass, fat yield and axial resin channel of high and low fat mass type of Pinus massoniana was studied. The preliminary results showed that: 1. The lipid yield and fat-producing capacity of high-fat and low-fat-fat varieties varied widely, and the area, number and diameter of resin road also differed; 2. The resinous area, diameter and yield The correlation coefficients are γ = 0.629 and γ = 0.641, respectively.3. According to the formula of calculating the fat-producing capacity, the diameter or area of the resin can be determined, and the corresponding fat-producing capacity can be obtained as the identification of high and low yield Lipids based on the estimation.
