摘要
介绍农艺覆盖技术在黄河三角洲盐碱地改良中的应用效果。系统地分析实施农艺覆盖措施后盐碱地土壤容重、土壤孔隙度、土壤毛管孔隙度和非毛管孔隙度及通气孔隙度、土壤饱和导水率、土壤有机质、土壤各类养分、土壤含盐量等参数的变化规律;并对典型农作物的产量变化情况进行分析。研究成果对盐碱地的改良具有借鉴意义。
This paper tries to evaluate the saline -alkali land amelioration in Yellow River Delta by analyzing changes of soil index, including soil bulk density, porosity, capillary porosity, noncapillary poropsity, aeration porosity, hydraulic conductivity of saturated soil and content of organic , nutrients and salt , before and after planting saline -alkali land with plants .Additionally , pro-duction variations of typical arboricultural products in this region are analyzed .Results concluded can be a reference for further study on saline-alkali land amelioration .
