为摸索铁矿水土流失区治理最佳树种,为今后综合治理提供科学依据,我们经二年多的试验、观测、分析,结果表明:黄檀、胡枝子等阔叶树种在矿区水土流失区种植成活率可达90%以上,且抗逆性强,速生快长,种植当年枝梢生长150cm以上,第二年400cm以上,平均覆盖率达80%以上。该树种枝叶茂密,根系发达,固土保水效果显著。该树种与草带配置措施能减少矿区土壤侵蚀68.7%。
In order to explore the best tree species for soil erosion control in iron mines and provide a scientific basis for future comprehensive treatment, after more than two years of experiment, observation and analysis, the results showed that broad-leaved species such as Dalbergia and Lespedeza are planted in the soil and water loss areas of mining areas. The rate of up to 90%, and strong resistance, fast growing fast, growing branches shoot more than 150cm, the second year more than 400cm, the average coverage rate of 80% or more. The tree species of dense foliage, developed root system, soil water retention effect is remarkable. The tree species and grass belt configuration measures can reduce soil erosion 68.8%.
