土质坝坝坡易遭暴雨径流冲蚀而破坏,草皮护坡是常用的一种护坡措施.山东省招远市采用当地野生的结缕草进行坝坡防护,取得良好效果。结缕草耐旱、耐寒、耐瘠薄、耐践踏碾压。抗逆性强,根系发达,茎叶茂密,繁殖生长快,是优良水土保持草种。该市勾山水库下游坝坡,1990年按照一定的栽培、管护技术进行结缕草护坡,护坝面积2.67万m2,栽植成活率达98%,两年后完全覆盖坝面,经6个汛期32次暴雨袭击,坝坡未发现水毁现象,较采用人工培植的专用草皮护坡节省资金13.35万元。结缕草草皮护坡已在招远市库坝工程中推广应用。
Soil dam slope easily eroded by storm runoff and destruction, turf slope protection is commonly used as a slope protection measures. Zhaoyuan City, Shandong Province, using the local wild Zoysia slope protection, achieved good results. Zoysia drought, cold, resistance to infertility, trample resistant rolling. Strong resistance, root system developed, stems and leafy, reproductive growth, is an excellent soil and water conservation grass. The dam of the lower reaches of the city hooks the reservoir in 1990 according to a certain cultivation, management and protection technology Zoysia slope protection, dam area of 26700 m2, planting survival rate of 98%, two years after the dam completely covered by the There were 32 rainstorms in 6 flood season and no water damage was found on the dam slope, which saved 133,500 yuan compared with the special turf slope protection by artificial cultivation. Zoysia sod protection has been Zhaoyuan Cuoba project to promote the use of.
