枫香是在观赏、药用、用材方面都有着重要作用且颇具潜力的造林绿化树种，为了加快培育优质的枫香苗木，笔者根据枫香的生长特性，采用不同的轻基质组配、不同的栽种密度和是否进行苗期大小苗分级的方法设置7个处理，对枫香苗木进行容器育苗试验。结果表明：使用LQ基质的处理组在种苗保存率、Ⅰ级苗率、合格苗出圃率、每平方米合格苗出圃数、平均苗高和平均地径等方面均高于使用SX基质或LZ基质的处理组。在轻基质组配和分盘处理相同的情况下，采用143株/m2的密度培育枫香容器苗，较采用195株/m2、238株/m2密度培育枫香苗有着更高的保存率、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。而进行大小苗分级培养的处理组与未分级培养的处理组在种苗成活率、合格苗出圃率、每平方米合格苗出圃数等指标上差距不大，但进行分级处理后的大苗盘的Ⅰ级苗率远高于未分级组和小苗组。
楓香是在觀賞、藥用、用材方麵都有著重要作用且頗具潛力的造林綠化樹種，為瞭加快培育優質的楓香苗木，筆者根據楓香的生長特性，採用不同的輕基質組配、不同的栽種密度和是否進行苗期大小苗分級的方法設置7箇處理，對楓香苗木進行容器育苗試驗。結果錶明：使用LQ基質的處理組在種苗保存率、Ⅰ級苗率、閤格苗齣圃率、每平方米閤格苗齣圃數、平均苗高和平均地徑等方麵均高于使用SX基質或LZ基質的處理組。在輕基質組配和分盤處理相同的情況下，採用143株/m2的密度培育楓香容器苗，較採用195株/m2、238株/m2密度培育楓香苗有著更高的保存率、Ⅰ級苗率和閤格苗齣圃率，且平均苗高、地徑以及苗木整齊度也更優。而進行大小苗分級培養的處理組與未分級培養的處理組在種苗成活率、閤格苗齣圃率、每平方米閤格苗齣圃數等指標上差距不大，但進行分級處理後的大苗盤的Ⅰ級苗率遠高于未分級組和小苗組。

Liquidambar formosana is a considerable potential afforestation species that plays an important role on ornamental, medicinal, timber, in order to accelerate the development of high-quality seedlings of L. formosana, according to its growth characteristics, using the ways of different light matrix groups, different planting density and whether size grading of seedlings, 7 treatments were set to make container seedlings tests. The results showed that: in treatment groups using LQ matrix, the seedlings survival rate, grade Ⅰ seedling rate, qualified seedling rate, the number of qualified seedlings per square meter, average height and average diameter, etc. were higher than that of treatment groups using SX matrix or LZ matrix. In the case of with the same light matrix group and sub-plate treatment, container seedlings of L. formosana was cultivated with the density of 143/m2, compared with 195/m2, 238/m2 have a higher survival rate, grade Ⅰ seedling rate, qualified seedling rate, and average height, diameter and uniformity of seedlings were better. The indicators of seedlings survival rate,qualified seedling rate, the number of qualified seedlings per square meter of treatment group with size grading of seedlings have no wide gap from that of without size grading of seedlings, but after gradingⅠ level seedlings rate was much higher than that of in unrated group and the group seedlings.
