摘　　要：为了绿化陡峭坡面,2017年3月中旬在甘肃省天祝藏族自治县城北侧华藏寺镇南山村G 338国道3 km+700 m处护坡地带,采用在坡面上钻孔,注水后带泥浆插入易生根的旱柳(Salix matsudana Koidz)插杆进行扦插造林(简称插杆微创造林)。结果表明,护坡插杆微创造林均能形成一定的植株和盖度,达到固土和绿化坡面的目的。其中插杆截留长度80 cm,垂直坡面(角度90°)插洞深60 cm,扦插后插杆顶端在坡面外露20 cm的栽植成活率、单株萌芽数、新梢长度、保存率、覆盖度最高,分别为92.18%、5.04个·株-1、282.46 cm,90.35%、85.82%,且绿化效果评价为优,在坡面绿化中可应用和借鉴。In order to green steep slope,the steep slope beside G 338 national road of nanshan village huazangsi town Tianzhu Tibetan Autonomous County,Gansu Province was holed on mid-March 2017,the cuttings of Salix atsudana Koidz were inserted into slope with mud after watered to forest(shorted cutting minimal wound foresting).The result showed that cutting minimal wound foresting on steep slope could formed certain plants and cover degree,and achieved the purpose of soil consolidation and greening to slope.The survival rate,single plant sprout number,new shoot length,preservation rate and cover degree of the cuttings(that were inserted into slope with length 80 cm,depth of hole 60 cm,angle of hole 90°,and top showed 20 cm out slope)were the highest in all treatment combinations,which were 92.18%,5.04 per plant,282.46 cm,90.35%and 85.82%separately,and the effect of greening was good,the technology should be applied and consulted in slope greening.
