摘　　要：四翅滨藜(Atriplex canescens)是藜科(Chenopodiaceae)滨藜属(Atriplex)的多年生半常绿灌木,具有速生、耐干旱、耐贫瘠、抗盐碱等优良特性,可用于水土保持和土壤改良。为探究四翅滨藜在浙江省新垦地上生长的适应性,及其在我国南方典型亚热带季风气候下生长发育的关键影响因素,本研究选择浙江省6个具有代表性的新垦土壤类型进行田间试验,测定四翅滨藜的生长、成活情况,运用主成分分析进行生长适应性评价,通过相关性分析和冗余分析得到影响四翅滨藜生长生活的主要因子。结果表明,在滨海盐碱土上种植四翅滨藜的成活率更高。在北仑和奉化试验点,四翅滨藜的地上部与地下部干物质质量显著(P<0.05)高于其他4个试验点,且分枝数相较于其他地区显著提高67.48%~346.47%。四翅滨藜适合在浙江省滨海盐碱地种植,土壤电导率、土壤pH、年降雨量、土壤碱解氮含量是影响四翅滨藜在浙江省生长和存活的主要因素,土壤电导率在9.51~14.28 dS·m^(-1)、土壤pH值在7.60~8.16、年降雨量在1087.7~1359.7 mm、土壤碱解氮含量在18.43~35.00 mg·kg^(-1)的地点更适宜种植四翅滨藜。Atriplex canescens is a perennial semi-evergreen shrub of the genus Atriplex,family Chenopodiaceae.It has excellent characteristics of rapid growth,drought tolerance,barren tolerance,and salt and alkali resistance.In order to explore the adaptability of Atriplex canescens to the newly cultivated land in Zhejiang Province of China and the key factors affecting its growth and development in the typical subtropical monsoon climate,six representative sites of newly cultivated soil in Zhejiang Province were selected,and the survival and growth of Atriplex canescens were analyzed to determine its growth adaptability at each site.The main influencing factors were obtained through correlation analysis and redundancy analysis of the growth and living conditions of Atriplex canescens and climatic factors and soil environmental factors in different regions.The results showed that the survival rate and growth rate of Atriplex canescens planted in coastal salinic-alkali soil were higher than those planted in yellow and red soil.The dry matter weight of aboveground and underground parts in Beilun and Fenghua was significantly(P<0.05)higher than that in the other four areas,and the branching number was increased significantly by 67.48%-346.47%compared with the other areas.The soil electrical conductivity,soil pH value,annual rainfall and soil alkali hydrolysable nitrogen content were the main factors affecting the growth and survival of Atriplex canescens in different regions.In conclusion,Atriplex canescens could be planted in coastal saline-alkali land in Zhejiang Province.Priority should be given to planting sites with soil electrical conductivity of 9.51^(-1)4.28 dS·m^(-1),soil pH value of 7.60-8.16,annual rainfall of 1087.7-1359.7 mm and soil alkali hydrolysable nitrogen content of 18.43-35.00 mg·kg^(-1).
