选用泥炭、炭化稻壳、蛭石、珍珠岩混合配制成9种育苗轻基质,通过对中国鹅掌楸容器育苗试验,进行基质配方的选择研究。结果表明,使用不同配方的轻基质培育的中国鹅掌楸苗木在苗高、地径、根系、单株干生物量上差异显著, M9配方轻基质(泥炭50%+炭化稻壳50%)育苗效果最好,当年苗木(4月龄)高8．10 cm,地径3．43 mm；移植原基质中继续培育1年的苗高达到38．7 cm,地径7．9~10．0 mm,苗木粗壮,根系发达。
選用泥炭、炭化稻殼、蛭石、珍珠巖混閤配製成9種育苗輕基質,通過對中國鵝掌楸容器育苗試驗,進行基質配方的選擇研究。結果錶明,使用不同配方的輕基質培育的中國鵝掌楸苗木在苗高、地徑、根繫、單株榦生物量上差異顯著, M9配方輕基質(泥炭50%+炭化稻殼50%)育苗效果最好,噹年苗木(4月齡)高8．10 cm,地徑3．43 mm；移植原基質中繼續培育1年的苗高達到38．7 cm,地徑7．9~10．0 mm,苗木粗壯,根繫髮達。

9 seedling formulas of light medium were made from mixture of peat, carbonised rice husk, vermiculite and per-lite. Containerized seedling method was applyed to plant Liriodendron chinensis ( Hemsl. ) Sarg. to choose better substrate formula. The results showed that there were significant differences in seedling height, ground diameter, root system and dry biomass per plant among the 9 formulas. The young plants with formula M9 ( peat 50% + carbonised rice husk 50%) grew the best than the other 8 formulas, its height and ground diameter ( age of four months) were 8. 1 cm and 3. 43 mm respec-tively. And when it was transplanted and continued to cultivate in original formula, then its height could reach 38. 7 cm and ground diameter could be 7. 9~10 mm, and the tree trunks and roots presented strong.
