摘要
加强冬季垂直绿化植物筛选和应用研究有助于提高我国南方冬季园林绿化水平。以滨柃(Eurya emarginata)、含笑花(Michelia figo)和红花檵木(Loropetalum chinense var.rubrum)3种常绿灌木为研究对象,采用生态基质和轻基质进行垂直栽培,通过对控水和复水处理中株高增长量、总生物量、根冠比、叶绿素含量、超氧化物歧化酶(SOD)活性、过氧化物酶(POD)活性和可溶性蛋白(SP)含量等抗旱性能指标的测定与分析,筛选最佳栽培基质和水分管理措施。结果表明,三种植物抗旱性综合评价由大至小依次为滨柃、红花檵木和含笑花,且采用轻基质栽培滨柃和红花檵木,以及采用生态基质栽培含笑花有利于提高杭州冬季常规温度下的栽培效果,其生物量和根冠比分别提高1.6%~36.8%和20.2%~41.1%,灌溉周期可以达到20天左右。
Exploring the vertical cultivation techniques helps improve the economic,ecological,and landscape benefits of urban garden greening in south China in winter.In this study,three evergreen shrubs,Euryaemarginata,Micheliafigo,and Loropetalumchinense var.rubrum,were cultivated in ecological substrates and light substrates under vertical cultivation conditions.Through the determination and analysis of drought-resistant performance indexes,such as plant height growth,total biomass,root-shoot ratio,chlorophyll content,superoxide dismutase(SOD)activity,peroxidase(POD)activity,and soluble protein(SP)content in water control and rewater treatment,the optimal cultivation substrate and water management measures were selected.The results showed that the comprehensive evaluation of the drought resistance of the three plants in descending order was Euryaemarginata,Loropetalumchinense var.rubrum,and Micheliafigo,and the use of light substrate to cultivate Euryaemarginata and Loropetalumchinense var.rubrum and the use of ecological substrate to cultivate Micheliafigo were beneficial to cultivation.When cultivation of Hangzhou was done at a conventional temperature in winter,its biomass and root-to-shoot ratio increased by 1.6%-36.8%and 20.2%-41.1%,respectively,and the irrigation period could reach about 20 days.
