摘　　要：通过当地典型造林树种油松、侧柏在 4种营养土及对照土上的育苗试验 ,综合考虑技术及经济因素 ,选择“山坡草皮土 10 0 %”为培育当地主要造林树种的容器育苗基质。播种方法对比试验表明 ,采用先装土至容器袋上口 1 0cm ,然后点种、盖土可提高出苗率。播种深度对比试验表明 ,播深 0 5～ 1cm可提高油松。It selects '100% of slope turf' as the basic quality of container seedling for the main local afforestation through seedling tests of Chinese Pine and Oriental Arborvitae those are the typical trees suitable for local afforestation in 4 prescriptions of nourishing soil and compared soil and comprehensively considering technical and economic factors. The contrast test of seeding method shows that the rate of emergence can be increased if puts soil up to 1.0 cm lower the container mouth, then dibbles in the seeds and covers with soil. The contrast test of seeding depth shows that the rate of emergence of Chinese Pine and Oriental Arborvitae can be increased if seeding depth is 0.5～1.0 cm.
