摘    要: 毛竹Phyllostachys edulis竹材经拉丝可加工成竹席、竹筷和竹帘,是毛竹竹材加工利用中的重要产品。调查了179株不同胸径分布的毛竹,截取拉丝段竹杆按照4种不同的规格进行粗刨开片和拉丝,将毛竹拉丝段加工成竹席丝,竹筷条和竹帘丝。分析了不同规格竹片的刨片对竹拉丝碳转移的影响,不同胸径的竹拉丝对碳转移率的影响,并建立不同胸径单株毛竹与拉丝材产品的碳储量模型。结果表明:①4种不同规格竹片的竹青和竹黄粗刨碳转移率差异显著(P<0.05),竹筷条比竹席丝和竹帘丝碳转移要高;由于拉丝段的竹材随着壁厚的减小变窄的趋势,导致不同规格随着小头壁厚的减小,碳转移率呈逐渐下降。不同规格竹片的拉丝材平均综合碳转移率为34.11%。②不同胸径毛竹拉丝材生产的综合碳转移率为24.20%~41.83%,平均为32.51%。③不同胸径毛竹拉丝材生产的整株综合碳转移率为9.97%~29.30%,平均为18.09%;④建立不同胸径单株毛竹与拉丝材产品碳储量模型为y=0.006 5x2.236 2,R2=0.631 8。图5表3参12

Abstract:Bamboo stems can be made into filar products,such as bamboo curtain,mat,and chopsticker. We open and wiredrawing 179 bamboo stems which in different DBH (dimeter at breadth height) into four size of bamboo fila,and analyze the effect of fila size and bamboo stem DBH on carbon transfer ratio. The model of carbon stocks is also studied. Results show:1) Carbon transfer ratios of 4 different size fila are significantly different (P<0.05),and the carbon transfer ratio of mat are the highest. Total carbon transfer ratio of different size of bamboo flia is 34.11%. The carbon transfer ratio decreases gradually because of the decrease in thickness of bamboo stem. 2) Carbon transfer ratios of filar processed from different DBH range from 24.20% to 41.83%,with an average of 32.51%. 3) Total carbon transfer ratios of filar products with different diameters range from 9.97% to 39.30%,with a avarage of 18.09%. 4) Using the above established relationship between DBH and carbon storage of filar products,a formula is given:y=0.006 5x2.236 2,R2=0.631 8.[Ch,5 fig. 3 tab. 12 ref.]
