摘要
为筛选矿源腐植酸(MHA)和生化腐植酸(BHA)最佳施用浓度,推动蝴蝶兰产业绿色高效发展,本研究采用不同浓度的MHA和BHA处理蝴蝶兰,测定其叶片发育、光合作用、抗氧化能力及成花品质等指标。结果表明:施用不同浓度的MHA和BHA能促进蝴蝶兰叶片发育,提高干鲜重比与根冠比,促进花芽分化、延长花期,增加花序长度和花朵数量,提升叶片类胡萝卜素、叶绿素和可溶性糖的含量,增强超氧化物歧化酶、过氧化氢酶活性。同时,施用MHA和BHA可显著提升蝴蝶兰的生长发育水平并优化其开花特性。其中25 mg/L MHA、12.5 mg/L BHA条件下蝴蝶兰的生理表现与观赏价值均显著提升。研究结果可为提高蝴蝶兰的观赏与经济价值、改良其温室栽培技术、推动产业向绿色高效及可持续方向发展提供科学依据。
In this study,in order to screen the optimal application concentration of mineral humic acid(MHA)and biochemical humic acid(BHA)and promote the green and efficient development of Phalaenopsis aphrodite industry,P.aphrodite was treated with different concentrations of MHA and BHA to measure such indexes as leaf development,photosynthesis,antioxidant capacity and flowering qual⁃ity.The results showed that the application of different concentrations of MHA and BHA could promote the leaf development of P.aph⁃rodite,increase the dry-fresh weight ratio and root-crown ratio,promote flower bud differentiation,prolong the flowering period,in⁃crease the length of inflorescence and the number of flowers,increase the content of carotenoids,chlorophyll and soluble sugar in leaves,and enhance the activity of superoxide dismutase and catalase.At the same time,the application of MHA and BHA could signif⁃icantly improve the growth and development level of P.aphrodite and optimize its flowering characteristics.Among them,the physi⁃ological performance and ornamental value of P.aphrodite were significantly improved under the conditions of 25 mg/L MHA and 12.5 mg/L BHA.The results could provide a scientific basis for improving the ornamental and economic value of P.aphrodite,im⁃proving its greenhouse cultivation techniques and promoting the industry to develop in a green,efficient and sustainable direction.
