摘 要：
通过对白刺花(Sophora davidii)年生长周期内苗高、地径及冠幅的调查,研究了在石漠化地区不同造林密度对白刺花生长的影响。结果表明,在栽培密度为90 cm×90 cm时,白刺花的地径、苗高和冠幅达到最高,效果最好。方差分析表明,栽培密度对白刺花的苗高影响不显著,在一定密度范围内,对白刺花的地径和冠幅影响达显著水平。

摘 要：
The effects of different planting densities on the growth of Sophora davidii in karst rocky areas of Guizhou province were studied by investigating height, diameter and crown in the annual growth cycle. Results showed that the average ground diameter, plant height and crown were the highest in plant density of 90 cm×90 cm in four plant densities. The analysis of variance showed that the effects of density on the height were not significant in karst rocky area. The effects of density on the diameter and the crown were significant in a certain density range.
