沿海地区丝棉木引种生长适应性

Growth Adaptability of Euonymus maackii in Coastal Areas

[目的]研究沿海地区丝棉木引种生长适应性。[方法]以2年生丝棉木实生苗为材料,比较其在江苏大丰和引种地山东聊城的生长适应性。[结果]沿海地区栽培的丝棉木成活率低于内陆碱性土壤地区;2年生丝棉木在沿海地区的高生长低于内陆碱性土壤地区,粗生长与后者差异不显著;供试材料在2种碱性土壤地区生长的物候期基本一致,开花结果均正常。[结论]丝棉木对碱性土壤具有较好的适应性,对盐碱地土壤具有一定适应性,经人工干预可做绿化栽培。

[Objective]To study growth adaptability of Euonymus maackii in coastal and introduction areas. [Method]The growth adaptability of 2-year-old Euonymus maackii seedlings in Dafeng,Jiangsu Province and Liaocheng,Shandong Province were compared.[Result]The survival rate of Euonymus maackii in coastal areas was inferior to that in inland alkaline soil areas. The high growth of 2-year-old Euonymus maackii in coastal areas was inferior to that in inland alkaline soil areas. The phenological period of the tested materials was basically the same in the two alkaline soils,and the flowering and results were normal.[Conclusion]Euonymus maackii has good adaptability to alkaline soil,and has certain adaptability to saline and alkaline soil and can be cultivated by artificial intervention.
