摘要
为研究不同泡桐品种在湖北低山丘陵区的生长适应性及不同造林密度对泡桐幼林生长量的影响,在京山市虎爪山林场对6个不同泡桐品种1 a生苗期生长量及3种不同造林密度的泡桐幼林生长量进行调查分析。结果表明:中桐1号表现最为优良,与9501相比,胸径生长量提高51.38%,树高生长量提高37.56%;造林密度对泡桐胸径和树高生长量的影响达到显著水平,胸径和树高生长量均随种植密度增大而降低。
To study the growth of different Paulownia in Hubei province and effects of different planting densities on the growth of young Paulownia trees,the growth of 6 different Paulownia varieties at the seedling stage of one year and the growth of 3 young Paulownia trees with different planting densities were investigated and analyzed in the Huzhao Mountain Forest Farm of Jinshan city.The result showed that the no.1 of Zhongtong had the best performance,Compared with 9501,the DBH growth increased by 51.38%and tree height by 37.56%.The effect of density on DBH and tree height were significant,the DBH and tree height of Paulownia decreased with the increase of planting density.
