摘　　要：通过在公路边坡对香根草3种反季节保护性栽培技术措施的研究，结果表明：在公路边坡采用保护性栽培技术措施进行香根草反季节种植是可行的；以香根草采用打浆覆膜保护性栽培措施处理最好，成活率达83．3％，株高、分蘖、根系深度等指标达到公路护坡的要求，同时坡面覆盖率达71％，护坡效果好；一般采用香根草进行的公路边坡治理成本约为20元／m^2左右，各处理仅较一般边坡治理种植增加投入0．25％～4．05％。Three cultivation techniques with the out-season protection for Vetiveria zizanioides planted on the sloping land along road were tested. The results show that three tested cultivation techniques are feasible and the cultivation technique including soaking root in damp soil for 5-10 rain and protective mulch is the best compared with other two techniques. The survival rate, plant height, tiller, root length and sloping cover rate used by the cultivation technique including soaking root in damp soil for 5- 10min and protective mulch accord with the demands of protecting sloping land. The cost of three cultivation techniques only increases by 0. 25%-4.05% compared with that of the tradition technique.
