摘    要:通过采集大棚土壤样品研究合肥地区大棚土壤肥力状况,结果表明,该地区大棚土壤有效磷提高较快,而有机质、有效钾含量上升较慢,土壤有酸化的趋势,0~10 cm土层硝酸盐比露地提高5.9倍,水溶性盐含量增加54.8%,硝酸盐和水溶性盐表层积累作用最大,随着大棚种植年限延长次生盐渍化程度加重。解决这一问题需要从土壤管理、施肥、灌溉、耕作、政策等多方面采取措施。

关 键 词:大棚  土壤肥力  土壤障碍因子  调控技术

Abstract:The fertility and obstacles factors of soil in plastic greenhouse in Hefei region had been studied.The results indicated that available P,available K in protected soil were 27.8%to 181.8% higher than those in opening ones.The content of available P increased fast,while the content of soil organic matter and available K enhanced slowly.In addition,the mulched soils tented to be acidified gradually,nitrate content and water-soluble salt content were accumulated greatly and the accumulation degree of surface-layer soil were the biggest.The obstacles factors of soil were greater with longer greenhouse planting.Many ways were needed to solve the problems,including soil manage,fertilization,irrigation, farming policy,etc.
Keywords:Plastic Greenhouse  Soil fertility  Soil Obstacle Factors  Control Techniques
