Abstract: A study was conducted on the influence of growth years of Puccinellia tenuiflora on the alkaline soils's content of total, effective, organic, and inorganic phosphorous and phosphatase activity. The result shows that with the increase of growth years of the grass, all the phosphorous nutrition also increase, reaching the peak in the third year. It is obvious that cultivating of the grass raises the alkaline soil's effective and organic phosphorous content. The soil phosphorous nutrition indexes are markedly correlated to phosphatase activity.

Key words: Grassland science, Puccinellia tenuiflora, Alkaline soil, Phosphorous nutrition, Phosphatase activity

摘要： 研究不同生长年限星星草对盐碱土全磷、速效磷、有机磷和无机磷含量及磷酸酶活性的影响.结果表明:土壤全磷、速效磷、有机磷和无机磷含量增加,三龄时达到最高值.星星草对盐碱土速效磷和有机磷含量有明显的影响;土壤磷素各项指标及磷酸酶活性之间都存在着一定的相关关系,其中磷酸酶活性与磷素各指标之间呈极显著相关.
