不同造林密度对泡桐幼林生长和林分蓄积量的影响
|
摘要
[目的]研究造林密度对泡桐幼林生长和林分蓄积量的影响。[方法]在广西自治区南宁市江南区苏圩镇,采用随机区组试验设计研究不同造林密度(625、833、1 111、1 666株/hm~2)对2年生泡桐生长、材积、蓄积量的影响,经过定位观测,探讨种群密度与胸径、树高、立木单株材积、冠幅、蓄积量、枝下高等的作用规律和相关模型。[结果]造林密度对胸径、冠幅及材积和蓄积量的影响达极显著水平;造林密度对树高、枝下高的影响达显著水平。[结论]泡桐幼林的合理造林密度在1 111~1 666株/hm~2。
[Objective] To study effects of different planting densities on saplings growth and stand volume of Paulownia.[Method]Effects of different planting densities( 625,833,1 111,1 666 trees/hm~2) on the growth,volume,and accumulation of 2-year-old Paulownia were studied with randomized block in Suwei District,Nanning,Guangxi Autonomous Region.The functional rule and correlation model between the population density of Paulownia and DHB,height,individual standing volume,crow cover,volume of forest-crop,live braches height were observed and analyzed.[Result]Effects of density on the DBH,the crow cover,the individual standing volume,the volume of forest-crop were extremely significant,and effects of density on tree height and height under the branches were significant.[Conclusion]The reasonable density of Paulownia was suggested to be between 1 111 and 1 666 trees/hm~2.
