摘　　要：对油茶（Camellia oleifra）优良无性系采穗圃进行密度试验,比较研究了4种造林密度对采穗圃植株生长、穗条产量及质量的影响。结果表明：1～3年生油茶采穗圃的适宜初始密度为9999株/hm2,3年生时单产穗芽量达163.41万个/hm2,对养分和空间利用率最高,综合经营效益最好。Density test on cutting orchards of Camellia oleifera fine clones was taken to compare the effect of four kinds of planting density to plant growth,yield and quality of cutting orchards. The results showed that the suitable initial density of 1 ～ 3 year-old C. oleifera cutting orchards was 9 999 strain / hm2. Yield of scion per hectare was amounted to 1. 6341 million,having maximum utilization of nutrients and space and the best management efficiency at 3-year-old C. oleifera cutting orchards.
