摘　　要：石质山地立地条件差,土壤瘠薄干旱,造林难度大,部分地块历经多次造林,均出现成活率和保存率低,造林效果不理想。为解决石质山地的造林困难,真正彻底消灭荒山,湄潭县通过造林综合配套技术试验,选用大穴整地、容器苗造林、覆盖灌草等造林综合配套技术,实行专人管护和割灌抚育,造林成活率和保存率均分别达95%、90%以上,苗木长势良好,造林成效明显。The site condition of stony mountain area is poor, the soil barren is dry, the afforestation is difficult, some plots have been afforestation many times, all have the survival rate and the preservation rate is low, the afforestation effect is not obvious. In order to solve the afforestation difficulties in the Rocky Mountains, and truly completely eliminate the barren mountains, Meitan County through the comprehensive technical test of afforestation, the selection of large caves, nutrient bag seedlings afforestation, shrub weed cover and other afforestation comprehensive supporting technology, the implementation of personal care and swamping, afforestation survival rate and preservation rates of 95%, 90%, respectively;seedlings grow well and the afforestation effect is obvious.
