Abstract: In the present paper, nutrient of soil salinity on planting Puccinellia tenuiflora in same, and various age are studied, and compared with Puccinellia tenuiflora in the natural soil. With the time increasing of planting Puccinellia tenuiflora, in 0~10cm soil, organic matter content and total nitrogen content are trend to raised, total phosphorus content are raised a little;total potassium content are changed on clearly, total sodium content, total calcium content and total magnesium are reduced in varying degrees.

Key words: Puccinellia tenuiflora, soil salinity, organic matter content of soil, total nitrogen content of soil, total phosphorus content of soil, total potassium content of soil, total sodium content, total calcium content of soil, total magnesium conten
