怀化紫色土造林树种选择及引种栽培技术研究

A Study of the Selection of Afforestation Tree Species and Practical Forestry Technology in Purple Soil in Huaihua

运用近自然营造和生态管护理论,采用“广泛采种、集中育苗、即起即栽”创新配套培育方法,通过长期试验观察,筛选出适合怀化紫色土生长的珍贵树种49种,提出优先发展黧蒴栲、香樟、秃瓣杜英、木荷、大叶榉树、猴欢喜、泡桐等7个树种.

Applying the theory of near-natural afforestation and ecological management,and using innovate supporting cultivation methods of“extensive seed collection,concentrated seedling raising,instant planting after lifting”,and through long-term experiments and observation,49 species of precious trees suitable for the growth of Huaihua purple soil were selected.Seven species of trees,including Castanopsis fissa,Cinnamomum camphora,Elaeocarpus glabripetalus,Schima superba,Zelkova schneideriana,Sloanea sinensis and Paulownia fortunei,are put forward to be developed as a priority in the purple soil of Huaihua.
