滴灌技术在墙面绿化中的应用研究

[目的]解决滴灌技术在墙面绿化中的应用问题.[方法]研究不同滴灌方式、连续滴灌时间及滴灌时间间隔对垂直绿化植物彩叶草生长及其基质持水特性等的影响.[结果]滴灌均匀布水的彩叶草各项指标优于滴灌顶端布水处理的彩叶草.两种处理最优状态比较,滴灌均匀布水处理比滴灌顶端布水处理彩叶草株高增加8.8％和冠幅增加14.5％.滴灌间隔2d的处理彩叶草株高和叶片数达到最大值,与对照相比,株高增加0.09％,冠幅增加11.7％.比较彩叶草生长效果,确定连续滴灌4min后间隔2d的滴灌方式有利于植物稳定生长.[结论]该研究可为华南地区垂直绿化滴灌技术的成熟应用提供参考.

Application of Drip Irrigation Technology in Wall Greening

[ Objective ] To solve the application issue of drip irrigation technology in wall greening. [ Method] By studying the drip irrigation methods, the continuous drip time and the effects of drip intervals on the vertical plants coleus growth and matrix effects such as water retention characteristics. [ Result] Drip uniform is superior to drip form top treatment in the indicators of Coleus. By comparing two optimal treatments, it was found that drip uniform increased by 8.8% in height and crown by 14.5% than drip from top treatment Coleus plant. Drip irrigation in- terval 2 d processing Coleus reached the maximum in height and the number of leaves. Compared with the control group, its plant height in- creased by 0.09% and the crown increased by 11.7%. As to the Coleus growth effects, the interval 2 d after 4-minute continuous drip manner is conducive to the stable growth of the plant. [ Conclusion] The study can provide a reference for the application of vertical greening drip irri- gation technology in southern area.
