采用不同的轻基质组配、不同的栽植密度、苗期大小苗分级的方法开展枫香容器育苗试验。结果表明：采用泥炭—谷壳轻基质比泥炭—珍珠岩轻基质、泥炭—椰糠轻基质培育枫香苗木，可以获得更高的存活率、Ⅰ级苗率和合格苗率，以及最大的枫香苗木生长量和最高的每平方米合格苗数；采用密度143株? m-2培育的枫香容器苗，比密度195、238株? m-2培育的枫香苗有着更高的存活率、Ⅰ级苗率和合格苗出圃率，且平均苗高、地径以及苗木整齐度也更优。分级培养后，枫香苗木的平均地径、平均苗高、Ⅰ级苗率、合格苗率及每平方米合格苗数均表现为大苗组＞不分级组＞小苗组，存活率、Ⅱ级苗率均表现大苗组＜不分级组＜小苗组，枫香苗木3个处理组间的存活率、合格苗率以及每平方米合格苗数3个指标间差别均不大，但进行分级处理后大苗组的Ⅰ级苗率远高于未分级组和小苗组。

Container nursery trials of Liquidambar formosana of different light matrix group ,different planting densities and different seedling size grading were performed .The results shows that compareing with the peat-perlite light matrix and the peat-perlite light matrix,the peat-chaff main components matrix had higher survival rate ,gradeⅠseedling rate and qualified rate,and also had the highest seedling growth and qualified seedling amount per square meter of Liquidambar formosana container seedlings .143 plants?m-2 density cultivation,compared with the 195、238 plants? m-2 density cultivation,had higher survival rate,gradeⅠseedling rate and qualified rate ,and higher average seedling height and average basal diameter ,and better uniformity too .After the seedling classi-fication,average seedling height , average basal diameter , gradeⅠseedling rate , qualified rate and qualified seedling amount per square meter of Liquidambar formosana all had the highest index in seedling group , then the no-grade group, then the young group.The survival rate and the grade Ⅱseedling rate shows the index of seedlings group <no-grade group<young group .The index of survival rate ,qualified rate and the qualified seedling amount per square meter among 3 groups were non-significant ,but far higher in the seedlings group then the unrated group and the young group .
