地堰黄花水土保持效益研究

A Study on the Effects of Citron Daylily on the Water and Soil Conservation of Terrace Edge

利用生态学原理,对山东省山地丘陵区梯田地堰栽植的黄花在涵养水源,保持水土方面的效应进行了观测。结果表明:地堰黄花具有改善土壤物理性状,提高土壤渗透速度,减少土壤侵蚀量的作用,其水土保持效益和经济效益都非常显著,是一种开发利用和保护地堰的有效植物。

Based on the priciples of ecology,the effects of citron daylily on water source maintain- ing and water and soil conservation of terrace edge were observed in area of mountain and hill in Shandong province.The results are as follows:the citron daylily could improve soil physical characteristics,increase the soil permeability and prevent soil from eroding.It has considerable benefits of soil and water conservation and ecology,Obviously,the citron daylily in terrace edge is a effective plant for developing, using and protecting of terrace edge.
