摘要 对无土栽培观叶植物的光合速率及环境因子动态变化的初步研究,结果表明,无土栽培观叶植物生长良好,光合速率较高,随时间变化,八角金盘光合速率变化较小,其次为万年青,最后为发财树。在晴到少云天气条件下,无土栽培观叶植物在一天中环境因子的变化较复杂。在无土栽培过程中,对耐萌植物八角金盘必须加强遮荫,同时进行喷雾,而万年青、发财树中性、阳性植物则需进行适当的遮荫,以达到最适的生长环境条件。 This paper is on the preliminary study on the dgnamic changes of net photosynthetic rate and environment factors of soiless foliage plant. It indicates: The soiless foliage. plants grow well and the rate net photosynthesis is fairly high,However,it will change with time changing,The rate of not photosynthesis of Fatsia japonicachanges less than that of Rohdea japonica and pachira macrocarpa, and the changes of thepachira macrocarpais the largest.The change of the environment factors about the foliage plant is complicated.In the process of soiless culturing, well shading and water spraying is needed properly shaded.
