伐桩处理对毛竹林生产力的影响研究

Effect of Stump Treatment on Productivity of Phyllostachys heterocycla cv. Pubesence Stand

    摘要
  • 摘要: 2012年11月至2015年7月，在浙江省安吉县用材林样地中对毛竹（Phyllostachys heterocycla cv．pubescens）伐桩进行0（CK）、225、450、675株/hm2 4种密度伐桩处理，研究其对毛竹林生产力的影响。结果表明，随伐桩处理密度的加大，样地中新竹生物量、新竹质量呈稳定提高的趋势；在伐桩处理密度为675株/hm2的毛竹用材林中，新竹生物量高达35.4 t/ hm2，较未伐桩处理林地提高了27.57%，大径级（DBH＞10 cm）新竹密度是未伐桩处理林地的1.43倍，新竹胸高处节间长度平均较未伐桩处理毛竹林提高了1.8 cm；伐桩处理能显著提高新竹的中、小径级竹材品质，继而提高毛竹材用林培育的整体经济效益。

     

    Abstract: From November 2012 to July 2015, experiments were conducted on stump cutting with four treatments namely 0, 225, 450 and 675 stumps/ha, in Phyllostachys heterocycla cv. pubescence stands in Anji, Zhejiang province. The result showed that biomass and quality of new bamboos at stands with different treatments increased with intensity of cutting. Stand with cutting intensity of 675 stumps/ha had biomass of new bamboo of 35.4 t/ha, 27.57% more than that of the control, density of large diameter new bamboo （DBH＞10cm）was 1.43 time of the control, and internode length at breast height was 1.8 cm longer than that of the control. The experiments also revealed that stump treatment could significantly improve the quality of medium and small diameter new bamboos.
