环渤海地区设施蔬菜是中国北方农业经济发展的“引擎”,是我国设施农业重点发展区域之一。近年来,随着设施蔬菜种植年限的延长,来自农业面源的土壤污染问题日趋严重。基于环渤海地区设施蔬菜发展现状,分析设施蔬菜土壤存在的次生盐渍化、酸化、连作病虫害、土壤板结、重金属污染等障碍,并在已实施的改良技术基础上提出了新的治理措施和发展对策。

The facility vegetable in the Bohai Rim is the“engine”for agricultural economic development in northern China,and it is one of the key developmental areas for facility agriculture in China.In recent years,with the extension of facility vegetable planting years,soil pollution from agricultural non-point sources has become increasingly serious.Based on the current situations of the development of facility vegetables in the Bohai Rim,the barriers of secondary salinization,soil acidification,continuous cropping diseases and insect pests,soil hardening and heavy metal pollution in the soil of facility vegetable were analyzed in this paper,and new control measures and development countermeasures were put forward on the basis of the implemented improvement technology.
