摘  要：
河北东部滨海平原区是我国冬枣集中产区之一,通过调查该地区冬枣园土壤条件,结果表明:冬枣园土地偏盐碱,存在土壤肥力偏低、通透性差、易于盐化和板结的问题,制约着冬枣产业生态化、可持续发展。利用现有果园生草技术对盐碱地冬枣园进行改良,可以增加土壤有机质含量,提高土壤通透性;明显降低土壤容重、增加孔隙度,使土壤入渗性能和持水能力明显提升,减轻盐化和板结的发生;改善土壤水分状况和理化特性,减少土壤水分蒸散,提高土壤水分利用率,改善土壤氮、磷、钾及微量元素等的营养水平,提高果园土壤的基础肥力,改善树体生长状况;使地面自由生态链形成,减轻病虫害。该文对适宜盐碱地冬枣园种植的草品种和生草管理方法进行论证,提出了改良现有土壤条件的方法,为推广盐碱地冬枣园植草技术,促进冬枣产业走上生态化、绿色可持续发展之路提出了解决方案。

摘  要：
The coastal plain area in eastern Hebei Province is one of the concentrated producing areas of winter jujube in China. Through the investigation of soil conditions in winter jujube orchard in this area,it is found that the land of winter jujube orchard is saline and alkali,and the characteristics of low soil fertility,poor permeability,easy salinization and hardening restrict the ecological and sustainable development of winter jujube industry. It was found that:improving the soil of winter jujube orchard in saline-alkali land by using existing orchard grass-growing technology can increase soil organic matter content and soil permeability;significantly reduce soil bulk density,increase porosity,improve soil infiltration performance and water-holding capacity,reduce salinization and compaction;improve soil water status and physical and chemical characteristics,reduce soil water evapotranspiration and improve soil water content;Improve the utilization rate of soil water,improve the nutrient level of soil nitrogen,phosphorus,potassium and trace elements,improve the basic fertility of orchard soil,improve the growth of trees,and form free ecological chain on the ground,reduce pests and diseases.This paper demonstrates the suitable grass varieties and management methods for winter jujube planting in saline-alkali land,and puts forward the methods for improving the existing soil conditions. It also puts forward solutions for promoting the technology of winter jujube planting in salinealkali land and promoting the industry of winter jujube to embark on the road of ecological and green sustainable development.
