湿地松在沙山治理中的试验示范研究

针对鄱阳湖区沙化土地实际，在多宝沙山进行湿地松移栽试验示范研究.结果表明：（1）两年生湿地松幼苗具有较强的抗逆性，比一年生苗移栽效果明显；湿地松幼苗能否在初植后存活是目前鄱阳湖沙地植被恢复所要解决的关键问题；移栽初期，一年生湿地松苗存活率低（30%～40%），而两年生苗湿地松对环境适应性强，初植存活率达80%以上，因此建议对鄱阳湖沙山的治理应优先选择移栽两年生湿地松苗；（2）在示范区周边村落开展育苗，不仅可以掌握湿地松的生长动态，便于进行科学研究，而且可以通过当地育苗促使苗木快速适应环境，保证移植后存活率，节省大量经费开支.

英文摘要:

According to the situation of sandy desertification land of Poyang lake area，we were transplanting the Pinus elliottii for experimental study and demonstration on Duobao sandy hills area.The result indicated：（1）The two seedling age Pinus elliottii with strong resistance； for one seedling age Pinus elliottii， It has low initial planting survival rate（30%～40%），and the two seedling age Pinus elliottii has higher initial planting survival rate（80%）.Therefore，we should first choose two seedling age Pinus elliottii used for environment governance.（2）Grow saplings in the surrounding villages，not only can control the growth of pinus elliottii in time，but also let trees quickly adapt to the local environments，guarantee the survival rate after initial planting，and save a lot of expenditure．
