雪灾受损毛竹材利用率比较及其效益分析

Research and Analysis on the Utilization Benefit and Damaged Bamboo Utilization of Moso Bamboo

对雪灾翻倒毛竹材进行3种不同加工方式的研究。结果表明:竹子胸径与竹材利用率及经济效益均呈二次曲线关系。竹席+重组竹地板加工的毛竹胸径在9.40cm处取得59.4%的最大综合利用率,在9.15,9.14cm处获得1.06,0.24元·kg-1的最大销售收入和利润。竹席+竹建筑模板加工的毛竹胸径在9.4cm处取得56.74%的最大综合利用率,在9.44,9.27cm处达到0.99,0.20元·kg-1的最大销售收入和利润。竹拉丝+竹片地板加工的毛竹胸径在10.33,10.63,10.39cm处取得58.27%的最大综合利用率和1.03,0.24元·kg-1的最大销售收入和利润。断竹的综合利用率为45.37%,销售收入为0.82元·kg-1,利润为0.12元·kg-1,明显低于正常毛竹约55%的综合利用率,1元·kg-1的销售收入和0.2元·kg-1的利润。研究认为要提高竹材利用率和经济效益需要注重对加工剩余物的利用,竹林培育应以提高单位面积产量和培育中等径级的竹材为目标。

Three processing ways of bamboo that turned over by ice and snow were done and the results show that the relation between the DBH and the utilization ratio was conical relationship,so does the relation between the DBH and the economic benefit.In processing way of bamboo mat and recombinant floor,the highest comprehensive utilization（59.4%）,sales income（1.06 yuan·kg^-1）and profits（0.24 yuan·kg^-1）was obtained at 9.40 cm,9.15 cm,9.14 cm respectively.In processing way of bamboo mat and construction formwork,The highest comprehensive utilization（56.74%）,sales income（0.99 yuan·kg^-1）and profits（0.20 yuan·kg^-1）was obtained at 9.40 cm,9.44 cm,9.27 cm respectively.In processing way of bamboo strips and floor,The highest Comprehensive utilization（58.27%）,sales income（1.03 yuan·kg^-1）and profits（0.24 yuan·kg^-1）was obtained at 10.33 cm,10.63 cm、10.39 cm respectively.As for the broken bamboo,the comprehensive utilization,sales income,profits（45.37%,0.82 yuan·kg^-1,0.12 yuan·kg^-1）were lower significantly than normal bamboo（55%,1 yuan·kg^-1,0.2 yuan·kg^-1）.The testing results points out that we should attach importance to bamboo waste utilization for raising the utilization ratio and economic benefit.The target of bamboo cultivation is attach more importance to improving output and cultivating medium diameter bamboo.
