中文摘要:

文章对韶关市翁源县林科所附近于2005年3月营造的12种不同造林技术措施黎蒴试验林进行研究,比较其中不同施肥措施、不同造林密度和不同整地规格下林木生长状况的差异,找出有利于黎蒴幼林生长的关键造林技术措施。研究结果表明:(1)12种不同造林技术措施下的树高、地径、冠幅等生长指标存在显著差异;(2)12号标准地树高生长显著高于其它标准地,8号标准地地径和冠幅生长最旺盛;(3)在不同施肥量的试验中,12号标准地黎蒴的生长最好;(4)在不同造林密度的试验中,8号标准地黎蒴的生长最好;(5)在不同整地规格的试验中,6号标准地黎蒴的生长最好;(6)聚类分析结果,将12个标准地林木的生长速度分为快、中和慢3种类型。

英文摘要:

In this paper, twelve kinds of testing plantations built in March 2005, applying different cultivation measures on hilly lands nearby Wengyuan Forestry Research Institute were studied. By setting up permanent sample plots (plot No. 1 - 12 ) and measuring all individuals of population, with the comparison of the tree growth under different fertilization measures, different planting densities and different size of planting hole, the key factors working on Castartopsis fissa and the most effective measurement were trying to find out. The result showed : (1) Tree growth among the 12 sample plots had significant differences. (2) The average tree height of No. 12 sample plot was distinctly higher than other samples, the status of average ground and crown growing in sample 8 were the best. (3) Under different fertilization measures, trees of sample plot 12 grew most prosperously. (4) Under different planting densities, No. 8 was the best testing sample plot. (5) Under different size of planting hole, No. 6 was the best testing sample plot. (6)Based on the cluster analysis, growth effect of the 12 sample plots could be divided into three kinds,rapid-growth plots, medium-growth plots and slow-growth plots.
