摘　　要：选择盐角草、盐地碱蓬、二色补血草、中亚滨藜、獐毛、星星草等6种典型盐生植物,采用野外原位种植,研究各生育期土壤速效氮、速效磷、速效钾、有机质、全氮含量的变化特征。结果显示,与生长初期相比,植物生长末期的盐角草、二色补血草、中亚滨藜、獐毛、星星草群落的土壤速效氮显著降低,中亚滨藜、獐毛、星星草群落的土壤速效磷显著降低,土壤速效钾虽有所降低,但并未达显著水平,土壤有机质和全氮随植物生长基本无变化。该结果可为未来盐碱地改良和治理提供参考。By means of field in situ method,six typical halophyte plants(Salicornia europaea,Suaeda salsa,Limonium bicolor,Atriplex centralasiatica,Aeluropus sinensis,Puccinella tenuiflora)communities were selected to study the effects of six plant growth on the characteristics of soil available N,available P,available K,organic matter,total N in different growth stages.The results showed,compared with the initial stage of plant growth,the soil available N contents in the communities of Salicornia europaea,Limonium bicolor,Atriplex centralasiatica,Aeluropus sinensis,Puccinella tenuiflora were significantly reduced in the late stage of plant growth,and the soil available P contents in the communities of Atriplex centralasiatica,Aeluropus sinensis,Puccinella tenuiflora were significantly reduced in the late stage of plant growth.Soil available K contents decreased along with the plant growth,but the decrement did not reach a significant level.Soil organic matter and total N did not change along with the plant growth.This study can provide theoretical reference and basis for the improvement and management of saline land in the future.
