摘　　要：在公路边坡香根草生物治理中应用新型抗旱保水剂和高效缓释肥料的试验证明,该技术措施既能保证香根草生长期间的水分和养分的有效供应,又能提高香根草的种植成活率和坡面覆盖率,达到较好的护坡效果。试验结果表明:既施用缓释肥料,又采用保水剂处理的香根草移栽成活率达93%,坡面覆盖率达90%,护坡效果极好,150 d后坡面香根草已形成草篱,能有效地拦截坡面水土,生物治理和景观效果较佳。The technical measure of applying new water absorbing reagent and fertilizer with high efficiency and slow release can not only ensure the effective supply of water and nutrients, but also improve the planting survival ratio and cover rate in management of Vetiveria zizanioides planted on sloping land along road. The results show that the transplant survival ratio and cover rate of Vetiveria zizanioides with applying the water absorbing reagent and fertilizer with slow release are up to 93% and 90% respectively and the Vetiveria zizanioides planted on sloping land after 150d forms the straw hedge which can effectively preserve soil and water in sloping land and get the better effects of ecological administer and landscape.
