摘　　要：为了探明贵州山区旱坡地冬春季干旱与油茶植苗成活率的关系,解决建园造林成本高等问题,采用田间试验研究了植苗时间、植苗方式和苗木类型对油茶成活率的影响。结果表明:用2年生芽砧嫁接营养袋苗于5月采取浇定根水和树盘盖膜方式植苗,其树苗成活率可达90%以上。结论:用该方法建园(造林)可1次性植苗成功,降低新植园和改造园的生产成本。To ascertain the relationship between the winter and spring drought in arid hillside of Guizhou mountain area and the survival rate of C. oleifera seedling and solve the problems of high cost for building garden and planting, field experiments were conducted to investigate the influence of seedling time, seedling method and nursery stock type on the survival rate of C. oleifera. The results showed that the survival rate could reach more than 90% if grafted with biennial bud stock, watering in May and mulching trees. Conclusion. the establishing method （forestation） could achieve successful disposable planting and reduce the production cost of the new and reconstructive C. olei fera plantations.
