在水土流失严重的丘陵地，对薄果相思进行了８年的试验，结果表明：薄果相思对于旱瘠立地具有较强的适应性，具有固氮作用，能改良土壤，提高地力；３年生时为胸径生长高峰期，连年生长量为１．０３ｃｍ，树高在１年生时为生长高峰期，年生长量为１．５２ｍ；７年生林分蓄积和生物量分别为２５．０ｍ３／ｈｍ２和２９．２ｔ／ｈｍ２，单株生物量（地上部分）为１４．６９ｋｇ／株；可采用萌芽和根蘖两种更新方式，两者采伐的效果与采伐时的林龄关系密切，萌芽更新４年的优于６年的，根蘖更新则６年的优于４年的。 The results showed that Acacia purpurea had strong adaptability to dry land and nitrogen fixation, which could improve the soil and improve the soil fertility. In 3-year-old For the peak DBH growth, annual growth was 1.03cm, tree height at 1 year growth peak, the annual growth was 1.52m; 7-year-old stand volume and biomass were 25.0m3 / hm2 and 29 .2t / hm2, and the biomass per plant (aerial part) was 14.69kg / plant. Two kinds of regeneration methods, germination and root tiller, could be adopted. The cutting effect of the two plants was closely related to the cutting age, Better than 6 years, the root tiller renewal is 6 years better than 4 years.
