在金沙江干热河谷地区引种黑荆树试验表明,黑荆树适应该区气候和土壤条件,生长良好;而在海拔1200m、1400m和2200m高度坡耕地与荒地生长的黑荆树状况不同,其地径、株高和冠幅存在显著差异,黑荆树在低海拔比高海拔生长良好,在坡耕地比荒地生长良好,表明海拔高度和立地条件对黑荆树生长影响很大,黑荆树作为金沙江干热河谷地区造林和水土保持的先锋树种,其应用前景广阔。 The introduction of black wattle in the Jinshan River dry and hot valley showed that the black wattle acclimated to the climate and soil conditions in this area and grew well. However, the black wattle growing at slopes of 1200 m, 1400 m and 2200 m altitude was different from the black wilts, There were significant differences in diameter, plant height and crown width. Wattle black wattle grew well at high altitudes at low altitudes and grew better than on badlands at sloping fields, indicating that altitude and site conditions had a significant impact on the growth of black wattle. Black wattle as Jinshajiang dry and hot valley afforestation and soil and water conservation pioneer tree species, its broad application prospects.
