摘要
采取盆栽控水法,研究多效唑对大叶黄杨、金叶女贞、紫叶小檗等绿篱植物抗旱性影响,以期为节水管理提供依据。结果表明：在干旱条件下,3种绿篱植物应用适宜浓度的多效唑可不同程度的增强抗旱性。单就抗旱性而言,大叶黄杨的适宜浓度范围为1.33-9.33 g/L,最佳浓度为6.67 g/L;金叶女贞和紫叶小檗适宜浓度均为1.33-4.00 g/L,最佳浓度为2.67 g/L。
The experiment is operated by pot-controlled water act,study the effects of paclobutrazol on the drought resistance of plants of hedge such as Euonymus japonicus,Ligustrum lucidum cv.and Berberis thumbergii cv.atropurpurea,so as to provide evidence for water saving management.The results showed that in drought conditions,the level of drought resistance of the three hedge plants were all improved at different degrees by using Paclobutrazol of appropriate concentration.As to the single index of drought resistance,the appropriate concentration of Euonymus japonicus ranges between 1.33 g/L and 9.33 g/L while the best one was 6.67 g/L;the appropriate concentration of Ligustrum lucidum cv.and Berberis thumbergii cv.atropurpurea ranges between 1.33-4.00 g/L while the best one was 2.67 g/L.
