Abstract

Abstract:

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.

Key words: halophyte, available N, available P, available K, organic matter, total N
