张家口市宿根花卉资源及绿化应用潜力分析
Analysis of perennial flower resources and the potential for greening application in Zhangjiakou City
摘要
Abstract
[Objective]The introduction of perennial flowers can effectively address issues such as short flowering periods,limit-ed species diversity,frequent replacements,and high maintenance costs associated with ornamental annual plant in Zhangjiak-ou.[Methods]A field survey was conducted to investigate the application of perennial flowers in representative green spaces in Zhangjiakou.Subsequently,various growth-related shape indexes of these flowers were analyzed.[Results]The region hosted a more diverse range of perennial flowers compared to annual plant flowers,totaling 17 families,41 genera,and 45 species.Notably,Compositae,Labiatae,and Irises exceeded annual plant flowers by 200%,150%,and 100%,respectively.Perenni-al flowers exhibited higher ornamental value,boasting 11 color variations,a 120% increase over annual plant flowers.Yel-low,blue,and white perennial flowers held higher proportions,constituting 24.4%,17.1%,and 14.6%,respectively.The flowering period for various perennial flowers extended from 210 to 240 days,surpassing annual plant flowers by 130% to 160% .Sprouting typically occurred from late March to mid-April,with variation in sprouting periods observed across different locations.Parks displayed sprouting 3～5 days earlier than on main roads.The coverage,overwintering survival rate,and wilt-ing rate ranged from 90% to 95%,81.6% to 100%,and 0% to 36.7%,respectively,for different perennial flower species.In the initial year,labor and maintenance costs for perennial flowers were 12 Yuan lower than for annual plant flowers,and be-yond the second year,late-stage maintenance costs were considerably lower for perennial flowers.[Conclusion]Zhangjiakou boasted a diverse array of perennial flowers with lower associated costs.The study indicated substantial application potential for perennial flowers in Zhangjiakou.关键词
