| 摘 要： | 采用工程措施为先导、生物措施为核心，在北方泥质海岸盐碱荒地上种植田菁、苜蓿两种牧草对土壤进行培肥效果研究。结果表明，种植田菁、苜蓿一个生长季结束后，土壤盐分和pH值下降；土壤有机质含量有所提高，氮、磷营养状况得到改善；与CK处理相比，两种牧草处理在10～50cm层次的肥土效果好于0～10cm层次；两种牧草相比较，田菁处理好于苜蓿处理。

| Abstract: | To using the engineering measures for the pilot,biological measures as the core,Sesbenia cannabina and Medicago sativa pasture were planted in the north coast of saline-alkaline muddy wasteland,which were used to research the effects on soil fertility.The results showed that Sesbenia cannabina and Medicago sativa were after the end of a growth season,soil salinity and pH values were decreased,soil organic matter content was increased,the nutritional status of nitrogen and phosphorus was improved.Contrast wi... |
