摘　　要：以河北燕山地区30个叶底珠群落为研究对象,对叶底珠生境土壤的化学性质进行测定分析。结果表明:30个叶底珠群落土壤化学性质存在差异,其中土壤pH值介于5.45~7.86之间,60.0%的样地属酸性土壤;有机质含量介于15.66~75.66 g·kg^(-1)之间,中高有机质含量土壤占86.7%;全氮含量介于0.85~4.36 g·kg^(-1)之间,中高氮肥力土壤占90.0%;全磷含量介于0.25~1.79 g·kg^(-1)之间,其中小于1.00 g·kg^(-1)的样地占93.3%;全钾含量介于13.49~23.01 g·kg^(-1)之间,均处于较高水平;碱解氮含量介于26.54~158.60 mg·kg^(-1)之间;有效磷含量介于2.26~11.86 mg·kg^(-1)之间,其中93.3%在2.00~10.00 mg·kg^(-1)之间;速效钾含量介于40.00~288.00 mg·kg^(-1)之间,差异很大,其中60.0%在100.00~200.00 mg·kg^(-1)之间。土壤pH值与有机质含量呈极显著负相关,与全氮、碱解氮含量呈显著负相关;有机质与全氮、碱解氮、速效钾含量呈极显著正相关;全氮与碱解氮、速效钾含量呈极显著正相关;全磷与速效钾含量呈显著负相关,碱解氮与速效钾含量呈极显著正相关。分析河北燕山地区叶底珠群落的土壤养分特征,探索叶底珠资源的地理信息,可为其开发利用提供参考。Soil nutrients of Securinega suffruticosa in Yanshan area were investigated.The pH of soils of S.suffruticosa ecological environments ranged from 5.45 to 7.86.The content of organic matter ranged from 15.66 to 75.66 g·kg^(-1).The contents of total nitrogen,total phosphorus and total potassium were 0.85~4.36,0.25~1.79 and 13.49~23.01 g·kg^(-1),respectively.The contents of alkali-hydrolyzable nitrogen,effective phosphorus and available potassium were 26.54~158.60,2.26~11.86 and 40.00~288.00 mg·kg^(-1),respectively.The pH and the contents of organic matter,total nitrogen,total phosphorus,total potassium,alkali-hydrolyzable nitrogen,effective phosphorus and available potassium varied greatly,indicating the great adaptability and diversity of S.suffruticosa in Yanshan area.Results of this study demonstrate that introduction and cultivation of S.suffruticosa in Yanshan area are feasible and necessary.
