卷荚相思在饶平不同种植密度的生长表现初步研究

The Study on Growth Performance of Acacia cincinnata at 4 Different Planting Densities at Raoping City Area

文章通过对饶平县4年生不同种植密度的卷荚相思的生长表现进行研究,结果表明:不同种植密度对卷荚相思的平均胸径、平均树高及单株材积无显著影响;因不同种植密度的平均每亩种植株数差异较大,因此平均每亩材积差异极显著。结果表明:卷荚相思是一个适宜各种种植密度的速生树种,其树高生长和胸径生长受环境的影响较小,所能适应的立地条件和环境条件较为广泛。

The study on growth performance at age of 4 years old of Acacia cincinnata are focused on 4 different planting densities at Raoping city area,the results indicated that there were no significant differetent among the 4 different densities with the average plant height and the average DBH,but for the different planting densities there were signifcant different with the average volumes per mu.A.cincinnata maybe one kind of the growth fast speices that can be suitable for different planting densities and most environment,and there were almost no effects on the plant height and DBH by enviornment.
