Growth Differences of Vitiveria Zizanioides and Its Impact on Environment in Sandy Land of Poyang Lake
[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. ② V. 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.
