扬州市郊区设施土壤障碍因子调查分析陈凡(农业农村部耕地质量监测与评价重点实验室/扬州大学,江苏扬州225127)摘要为摸清扬州市郊区设施土壤障碍因子,更好地指导耕地质量提升与作物科学施肥,在扬州市郊区设施农业园采集具有代表性的土壤样品,对采集到的70个设施土壤样品进行基本理化性状的测定。结果表明,土壤pH值较低、部分有效态微量元素含量过低、大棚连作等是影响扬州市郊区设施土壤生产功能的主要障碍因子。为提高土壤肥力,可以增施有机肥、微生物肥料和中量元素肥料来补充土壤缺乏元素,使土壤元素平衡,以此促进作物生长。关键词设施土壤;障碍因子;施肥;连作;江苏扬州中图分类号S316;S147文献标识码A文章编号1007-5739(2023)07-0159-05DOI:10.3969/j.issn.1007-5739.2023.07.044开放科学(资源服务)标识码(OSID):InvestigationandAnalysisofObstacleFactorsofFacilitySoilintheSuburbofYangzhouCHENFan(KeyLaboratoryofArableLandQualityMonitoringandEvaluation,MinistryofAgricultureandRuralAffairs/YangzhouUniversity,YangzhouJiangsu225127)AbstractInordertoclarifyobstaclefactorsoffacilitysoilinthesuburbsofYangzhouCity,andbetterguidetheimprovementofarablelandqualityandscientificfertilizationofcrops,representativesoilsampleswerecollectedinthefacilityagriculturalparkinthesuburbofYangzhouCity,andthebasicphysicalandchemicalpropertiesof70collectedfacilitysoilsamplesweredetermined.TheresultsshowedthatthelowpHvalueofsoil,thelowcontentofsomeavailabletraceelements,andthecontinuouscroppingingreenhousewerethemainobstaclefactorsaffectingtheproductionfunctionofthefacilitysoilinthesuburbofYangzhouCity.Inordertoimprovesoilfertility,organicfertilizer,microbialfertilizerandmediumelementfertilizercanbeaddedtosupplementsoilelementslackinginthesoil,andbalancesoilelements,soastopromotecropgrowth.Keywordsfacilitysoil;obstaclefactor;fertilization;continuouscropping;YangzhouJiangsu自2008年以来,蔬菜产业一直是江苏省种植业第一大产业,也是增加农民收入第一产业。其中,扬州市蔬菜尤其是保护地蔬菜一直面临着不少问题和挑战。扬州市位于江苏中部,长江与京杭大运河交汇处,气候温和,雨量充沛,农业资源丰富,是国家重要的商品粮基地。扬州市结合区域优势主...
