厚荚相思不同栽植密度试验结果表明，不同株行距组合在单位面积蓄积量、单株生长量及干形指标间存在显著差异。种植密度在1665株/hm2以上时，株距与行距相近时单位面积蓄积量较高；密度为1245，1005株/hm2时，株距小、行距大的组合的单位面积蓄积量优于株行距相近的组合，且同密度不同株行距之间单位面积蓄积量可提高11％～20％。不均衡行距试验显示，US16和US17处理有利于单株生长，且相同密度条件下，不均衡行距模式的单位面积蓄积量明显优于均衡行距的组合。

A plantation test was conducted to examine the effect of density on growth of Acacia crassicarpa. Significant differences in volume per unit area,individual growth and stem form were found among different row-spacing modes.The mode of 1 665 plants hm-2 which row was close to spacing had higher volume per unit area than other modes.For the density of 1 245 and 1 005 plants hm-2 ,the volume per unit area of modes with lower spacing and higher row were 1 1% to 20% higher than those which row was close to spacing.In uneven spacing test,the treatment US16 and US17 were conductive to individual growth.Under the condition of same density,vol-ume per unit area in the mode of uneven spacing was higher than those in the modes of even spacing.
