摘　　要：对应用平衡根系无纺布容器苗、塑料袋容器苗、蘸泥浆苗和裸根苗（对照）造林的8个树种的成活率、栽植初期生长量进行了分析,并比较了采用不同类型苗木造林时侧柏苗的造林成本。结果表明：应用无纺布容器苗、塑料袋容器苗、蘸泥浆苗造林的8个树种的平均成活率较裸根苗造林提高151.9%～522.8%,栽植当年平均新梢生长量提高325.0%～1475.0%;应用平衡根系无纺布容器苗（侧柏）与塑料袋容器苗（侧柏）的造林成本相当,比裸根苗降低30.5%～32.1%,蘸泥浆苗与裸根苗的造林成本基本相当。应用平衡根系无纺布容器苗造林,不仅造林成活率高,在造林初期苗木的新梢生长量大,生长状况良好,其造林成本也较低。An experiment was conducted to afforest with no-woven-cloth container seedlings with balanced root system, plastic container seedlings, seedlings with muding root, and bare-root seedlings （control） of eight tree species. The survival rate of seedlings and the height increment of current shoots were analysed, and the planting costs of Platycladus orientalis seedlings planted through different ways were also compared. Results show that the survival rates of the seedlings of these three types of afforestation increase by 151.9% -522. 8% and the mean height increments of current shoots by 325.0% - 1475.0% in the first year of afforestation compared with those of bare-root seedlings. Afforestation costs for seedlings with mudding root and bare-root seedlings are approximately equivalent, so do no-woven-cloth container seedlings with balanced root system and plastic container seedlings, and their costs decrease by 30.5% - 32.1% compared with that of bare-root seedlings. It indicates that afforestation with no-woven-cloth container seedlings with balanced root system is a feasible afforestation technology for its higher survival rate, earlier increment, lower cost and better growth status.
