五节芒幼苗水培的优化方法

Optimum Method for Hydroponic of Miscanthus floridulus

摘要: 五节芒(Miscanthus floridulus)是常见的野外群生禾本科芒属植物，在土壤污染植物修复方面具有广阔应用前景。但植物修复机理研究不够深入，水培实验是解决单因素影响机制的有效途径。通过总结其他植物水培方法和设置一系列五节芒水培方法试验，获得五节芒水培成功的最佳实验条件。结果表明：通过控制水培前五节芒植株的长势和根部的生长激素前处理方法、水培过程中使用正确的营养液配方(Hogland全营养液)、培养液不间断鼓气和根部光照等条件，成功完成水培五节芒实验。

Abstract: Miscanthus floridulus is a common wild population of Miscanthus, which has broad application prospects in soil contaminated phytoremediation. However, the study of phytoremediation mechanism is not thorough enough. Hydroponic experiment is an effective way to solve the single factor effect mechanism. By summarizing the hydroponics methods of other plants and setting up a series of water culture methods for Miscanthus floridulus, we obtained the best experimental conditions for the success of Miscanthus floridulus water culture. The results showed that: hydroponics method of Miscanthus floridulus can be successfully achieved by controlling the growth conditions of mangrove plants before hydroponics and the growth hormone pretreatment method in the roots, the correct nutrient solution formula (Hogland nutrient solution) in the hydroponics process, continuously irrigating the culture solution, and the roots lighting.
