研究了不同扦插密度下苗木的生长性状、质量、产量和生产成本。结果表明：不同扦插密度下，苗木的基径、高径比差异达显著或极显著水平，苗高和分枝数未达显著差异程度。随着扦插密度的增加，苗木基径下降，高径比增大，质量下降，整齐度更差，Ⅰ级苗比率和成苗率均下降，苗高和分枝数也呈下降趋势。综合苗木质量、产量以及生产成本，闽北及类似地区杉木扦插育苗的适宜密度为４．５～５万株／６６７ｍ２。
The seedling growth traits, quality, yield and production cost under different cutting density were studied. The results showed that under different cutting densities, the difference of base diameter and height to diameter ratio of seedlings reached significant or extremely significant level, and seedling height and branch number did not reach significant difference. With the increase of cutting density, the base diameter of seedlings decreased, the height to diameter ratio increased, the quality decreased, the uniformity was worse, the grade Ⅰ seedling rate and the seedling emergence rate decreased, the seedling height and branch number also showed a downward trend. According to the quality of seedlings, the yield and the cost of production, the suitable density of cutting propagation of Chinese fir in northern Fujian and similar areas is 4.5-500 / 667m2.
