摘要: 为了明确不同配方营养液对金钗石斛(Dendrobium nobile)生长和品质的影响,以金钗石斛幼苗为研究对象,设置6种不同营养液处理,观测其存活率、新芽数量、茎长、茎粗、节间距、叶片长度、叶片宽度、茎鲜重等生长指标以及可溶性糖含量、可溶性蛋白质含量、游离氨基酸含量等品质指标。结果表明,各营养液处理与CK相比,幼苗存活率未表现出显著差异;T2在促进金钗石斛新芽数量方面表现出明显优势;T2的茎长、节间距、叶片长度、叶片宽度、茎鲜重均相对高于CK及其他营养液处理,在幼苗生长方面表现相对较好;T1、T2和T5的可溶性蛋白质含量、可溶性糖含量、游离氨基酸含量均处于相对较高水平,在金钗石斛幼苗品质方面表现相对较好;隶属函数分析表明,T2综合得分最高,为0.72分。综合来看,T2营养液在金钗石斛幼苗生长和品质方面均表现相对较好。

Abstract: To clarify the effects of different nutrient solution formulations on the growth and quality of Dendrobium nobile, six different nutrient solution treatments were applied to Dendrobium nobile seedlings. Growth indicators including survival rate, number of new shoots, stem length, stem diameter, internode length, leaf length, leaf width, and fresh stem weight, as well as quality indicators including soluble sugar content, soluble protein content, and free amino acid content, were measured. The results showed that compared with the control (CK), no significant differences in seedling survival rate were observed among the nutrient solution treatments. T2 demonstrated a clear advantage in promoting the number of new shoots of Dendrobium nobile. The stem length, internode length, leaf length, leaf width, and fresh stem weight of T2 were relatively higher than those of CK and the other treatments, indicating relatively better performance in seedling growth. T1, T2, and T5 exhibited relatively high levels of soluble protein content, soluble sugar content, and free amino acid content, showing relatively good performance in seedling quality. Subordinate function analysis showed that T2 achieved the highest comprehensive score of 0.72. Overall, T2 nutrient solution performed relatively well in both the growth and quality of Dendrobium nobile seedlings.
