中文摘要	[目的]香根草(Vetiveria zizanioides)是保持水土的理想植物,研究香根草在鄱阳湖沙区的生长情况及对沙区环境的影响,为南方治沙提供参考。[方法]采用野外测量与室内试验相结合的方法,分析距湖距离和不同处理方式对香根草生长的影响以及香根草对土壤温度、湿度的影响。[结果]①距湖距离对香根草生长高度的影响不显著,对香根草的分蘖数影响显著;刈割和分蘖处理对香根草生长高度的影响不显著但有促进作用,刈割处理可以促进香根草的分蘖,分蘖处理不利于香根草的分蘖;生长期末,香根草各指标存在差异;②香根草可以降低土壤温度,增加土壤含水量;③距湖距离、香根草生长高度均与香根草分蘖数呈显著正相关(p<0.05);土壤温度与土壤含水量呈极显著负相关(p<0.01)。[结论]香根草在重度沙化区存活率高,距湖距离和不同处理方式影响香根草生长,香根草种植对沙区土壤具有改善作用。
英文摘要	[Objective]Vitiveria zizanioides is an ideal herb to maintain soil and water,study on the growth of V.zizanioides in sandy land of the Poyang Lake and its impact on sandy environment can provide a reference for the sand-control in Southern China.[Methods]Field investigation and laboratory experiments were conducted to study the influences of distance to the lake and different treatments on the growth of V. zizanioides,and the impacts of V.zizanioides on soil temperature and humidity.[Results]① The effect of distance to the lake on the height of V.zizanioides was not significant,while its effect on the tiller number of V.zizanioides was significant.Mowing and tillering treatments showed a positive effect on the height of V.zizanioides.The mowing treatment could promote the tillering of V.zizanioides while the tillering treatment was not conducive to the tillering of V.zizanioides.At the end of growth period,the indexes of V.zizanioides were different.②V.zizanioides could reduce soil temperature,but increase the soil water content.③ Both the distance to the lake and the growth height of V.zizanioides had a significantly positive correlation(p<0.05)with the tiller number of V.zizanioides.In addition,soil temperature and water content were significantly negatively correlated(p<0.01).[Conclusion]V.zizanioides has a high survival rate in the heavily sandy land.The distance to the lake and different treatment methods can affect the growth of V.zizanioides,and V.zizanioides planting can improve the soil in sandy land.
