摘要:
针对阿拉善右旗额肯呼都格镇城市绿化尚处一片空白,对当地硫酸盐型盐土掺拌 细沙土壤 改良,引进灌木、落叶乔木、常绿乔木适应性对比研究发现:引种地60 cm土层内均匀掺 拌细沙(原 土∶细沙=2∶1)处理土壤的含盐量、pH值等指标均显著低于对照,而有机质显著高于对 照土壤 ( P <0.05);引进树种在处理土壤的表现显著( P <0.05)优势于对照土壤的表现。从 而说明土壤拌 沙改良是当地一种行之有效而且效果显著的土壤改良方法;引进各树种适应能力由强到弱 的顺序 为:刺槐>多枝柽柳>紫穗槐>白榆>杏树>樟子松;且刺槐、柽柳、紫穗槐、白榆、杏树均极 显著高 于樟子松的适应能力( P<0.01);刺槐、柽柳、紫穗槐、白榆间无显著性差异(P>0.05 ),刺槐、柽柳 均显著(P<0.05)高于杏树的适应能力,紫穗槐、白榆、杏树间无显著性差异。综上所 述,研究区通 过土壤拌沙改良,能够成功引种刺槐、柽柳、紫穗槐和白榆4种园林绿化树种,在无条件 改良土壤时 可成功引种刺槐及柽柳
Abstract:
Plant introduction and cultivation for heavy alkaline and s aline soil were carried out Ekenhuduge Township in Alashan Right Banner of Inner Mongolia including shrub s,deciduous arbors,and everˉgreen arbors. It was found that after the sulfate type soil was improve d by fine sands within a layer depth of60 cm,salt contents and pH of the improved soil decreased,whereas,the c ontents of organic matter increased ( P <0.05).The performance of introduced plants grown in the impro ved were much better than those in the control,indicating that the application of fine sand was an e ffective way to improve soil.The adaptabiliˉ ties of introduced plant species from strong to weak were in the o rder of Robinia pseudoacacia L.> Tamaˉ rix ramosissima>Amorpha fruticosa L.> Ulmus pumila L.> Armeniaca sibirica L.> Pinus sylvestris var. mongolica.Moreover, the adaptabilities of R. pseudoacacia L., T.ram osissima,A. fruticosa L.,U. pumila L.,A. sibirica L. were all obviously stronger than that of P. s ylvestris var. mongolica(P<0. 01). There were no significant differences among R. pseudoacacia L.,T. ramosissima,A. fruticosa L., U. pumila L (P>0.05) ,and the adaptability of R.pseudoacacia L. and T . amosissima(P<0.05) were obviously stronger than that of A. sibirica L.,There were no signifi cant differences among A. fruticosa L.,U. pumila L. and A. sibirica L. It was concluded that such4garden sp ecies for beautification as R. pseudoacacia L.,T.ramosissima, A. fruticosa L.and U. pumila L. had been s uccessfully introduced through applying fine sand for soil treatment.When the condition f or improving soil is not favorable,R. pseudoacacia L. and T.ramosissima are the preferable plant species.
