安徽农学通报2023年02期蔬菜·水果·园艺不同电导率灌溉水对上海青生长的影响曹红霞赵伟*蒋丽媛杨圆圆李明明（渭南市农业技术推广中心，陕西渭南714000）摘要通过田间灌溉试验，研究不同电导率灌溉水对拱棚内种植的上海青植株生长及产量的影响。试验设置3种灌溉水处理，分别为电导率3.3mS/cm的井水（E1）、电导率1.9mS/cm的井水（E2）和电导率0.3mS/cm（E3）的雨水。结果表明，E3、E2的上海青出苗密度分别为140株/m2、122.7株/m2，显著高于E1；E2和E3较E1显著增加了上海青的小区产量、单株产量和根鲜重，增幅分别为5360%～10892%，260%～460%，333%～516%；与E1处理相比，E2和E3处理均显著增加了上海青的叶片大小。因此，在本研究地区，电导率高的灌溉水会影响上海青生长。关键词灌溉水；电导率；上海青；生长中图分类号S626文献标识码A文章编号1007-7731（2023）02-0055-04EffectsofIrrigationWaterwithDifferentConductivityontheGrowthofBrassicachinensisL.CAOHongxiaZHAOWei*JIANGLiyuanYANGYuanyuanLIMingming（WeinanCityAgriculturalTechnologyPromotionCenter,WeinanShaanxi714000）AbstractThroughfieldirrigationexperiments,theeffectofirrigationwaterwithdifferentconductivityonthegrowthandyieldofBrassicachinensisL.plantsgrowninthearchedshedwasstudied.Threeirrigationwatertreatmentsweresetupintheexperiment,wellwaterwithconductivityof3.3mS/cm(E1),wellwaterwithconductivityof1.9mS/cm(E2),rainwaterconductivityof0.3mS/cm(E3).TheresultsshowedthattheseedlingdensitiesofE3andE2treatmentswere140plants/m2and122.7plants/m2,whichweresignificantlyhigherthanthoseofE1treatment.ComparedwithE1,E2andE3treatmentssignificantlyincreasedtheyield,yieldperplantandfreshrootweightofBrassicachinensisL..Theincreaseswere5360%~10892%,260%~460%,and333%~516%.Thefreshweightincreasedby5360%~10892%,260%~460%,and333%-516%,respectively.ComparedwithE1treatment,E2andE3treatmentssignificantlyincreasedtheleafsizeofBrassicachinensisL..Therefore,inthisstudyarea,irrigationwaterwithhighconductivitywillaffectthegrowthofBrassicachinensisL..Keywordsirrigationwater;electricalconductivity;BrassicachinensisL.;growth上海青（BrassicachinensisL.）又称瓢儿白，属于大白菜的变种，是十字花科芸薹属的...
