| 摘 要： | 在盐碱土壤上种植星星草 (Puccinellia tenuif lora)群落后测定土壤氮、磷含量。结果表明 ,星星草在盐碱土壤上生长 2～ 3年后 ,土壤全氮含量、碱解氮含量 ,氨化强度、固氮强度 ,全磷全量、速效磷含量、有机磷含量、无机磷含量都增加 ,且星星草生长 3年比星星草生长 2年的各项指标都有增高的趋势

| Abstract: | Based on the study of P.tenuiflora community in saline alkali soil about the content of nitrogen and phosphorous,the results show that the content of total N,available N,the intensity of ammonification and nitrification,total P,available P,inorgnic and organic P are all increase.Furthermore,all indexes of growing P.tenuiflora for three years are more higher at some extend than growing P.tenuiflora for two years. |
