| 兰屿肉桂 Cinnamomum kotoense，属于樟科樟属常绿乔木，原产于我国，是良好的盆栽观叶
树种和园景树种。为了更好发挥兰屿肉桂的价值，提高栽培方法多样性，研究设置 2 个营养液配方，并
使用不同的浓度和不同栽培基质，探究其对肉桂幼苗水培生长的影响。结果发现配方 2（Ca(NO3)2 945
mg · L-1、K2SO4 440 mg · L-1、KH2PO4 350 mg · L-1、MgSO4 400 mg · L-1、FeSO4 · 7H2O 7.000 mg · L-1、
EDTA-2Na 9.300 mg · L-1、H3BO3 0.075 mg · L-1）稀释 500 倍处理下水培兰屿肉桂幼苗根系生长效果最好，
配方 2 稀释 700 倍处理下茎干叶生长效果总体最佳、生长量最佳，配方 2 稀释 900 倍处理下新芽萌发数
目最多。总体而言使用配方 2 进行水培表现更好。各组营养液 pH 和电导率规律性不明显。使用不同栽培
基质时，使用陶粒的水培兰屿肉桂生长明显优于使用石块和彩陶。 |

| Abstract: |
| Cinnamomum kotoense is a kind of evergreen tree species from Cinnamomum genus,Lauraceae
family. C. kotoense is originated from China and can be used as a kind of ornamental foliage plant and landscape
tree.Meanwhile,it is also widely used in medical fields and perfume industry. In order to take advantage of the
potential of C. kotoense and improve the the diversity of cultivation,this paper focuses on effects of different
formulations of nutrient solutions and different cultivating matrices in cultivating seedlings.The optimal
formulation and concentration of nutrient solution for root growing is Formulation 2（Ca(NO3)2 945 mg · L-1、
K2SO4 440 mg · L-1、KH2PO4 350 mg · L-1、MgSO4 400 mg · L-1、FeSO4 · 7H2O 7.000 mg · L-1、EDTA-
2Na 9.300 mg · L-1、H3BO3 0.075 mg · L-1） diluting with 500 dilution ratio.As for stem and foliage growth and
biomass of the seedlings,the optimal one is Formulation 2 diluting with 700 dilution ratio.Meanwhile, the optimal
one for improving sprouting of seedlings is Formulation 2 diluting with 900 dilution ratio.Generally, Formulation
2 behaves better in cultivating seedlings of C. kotoense. pH and electric conductivity of each experimental
groups show less differences in tendency.Compared with using stones and colorful ceramisites, using ceramisite
as matrices is good for the growth of hydroponic seedlings.These results have a certain reference value in high
quality cultivating and improving product quality of C. kotoense. |
