摘要
针对沈阳地区的气候及立地条件建立了3种混播组合模式,并运用了层次分析法(AHP)对其应用进行了评价,旨在为草花混播在沈阳地区的推广提供技术参考。结果表明:22块草花混播样地中有18块样地评价达到Ⅰ级、Ⅱ级标准,占总数的81.82%,说明草花混播组合应用效果较好,适合沈阳地区大面积推广应用;有4块样地评价在Ⅲ级、Ⅳ级,占总数的18.18%,主要因为该样块土壤条件较差、组合内品种配比不合理及播种密度较大等原因导致出现单一种强势现象。
Three composite patterns were set up on the climate and condition of Shenyang,and they were evaluated using AHP method in order to offer technical reference of herbaceous flowers mixture in Shenyang. The results showed that among 22 plots of mixture of herbaceous flowers, 18 plot reached I,Ⅱ grade, accounting for 81.82%. It suggested the application effect was better, and suitable for large scale application in Shenyang region; 4 belonged to Ⅲ, IV grade, accounting for 18. 18%,mainly because of a strong species phenomenon due to poor soil condition, unreasonable varieties proportion,denser sowing and other reasons.
