运用液压喷播技术进行植草护坡的研究

A Study on Hydraulic Seeding Technique for Slope Stabilization

液压喷播植草护坡机械化程度高、速度快、效果好、适应性广,是一种快速建立绿化草坪的植草护坡方法。选择广东省飞来峡水利枢纽工程开挖的典型坡面为试验区,研究了液压喷播技术在植草护坡中的应用。结果表明,液压喷播植草护坡的成坪速度主要受草籽的生态学特性、种子萌芽条件及生长环境等因子的影响,即与草籽种类、植物生长调节试剂及土壤状况与气候条件等因子密切相关。

Hydraulic seeding is an affordable, widelyapplicable and efficient mechanized technique to establish an extensively and actively growing vegetation cover for slope stabilization. A dug typical slope of the key water control project at Feilai gorge in Guangdong province was selected as the test plot to study the application of hydraulic seeding technique for slope stabilization. The result shows that the speed for the seededlawn to cover the slope surface effectively depends mainly on the ecological characters of the main species, the environmental condition for the seed germination and growth, and some other factors. These factors are closely related to the seed categories, the plantgrowinghelp chemicals, soil states, climatic conditions etc.
