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3.3 mS/cm的井水(E_(1))、电导率1.9 mS/cm的井水(E_(2))和电导率0.3 mS/cm(E_(3))的雨水。结果表明,E_(3)、E_(2)的上海青出苗密度分别为140株/m^(2)、122.7株/m^(2),显著高于E_(1);E_(2)和E_(3)较E_(1)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E_(1)处理相比,E_(2)和E_(3)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。Through field irrigation experiments,the effect of irrigation water with different conductivity on the growth and yield of Brassica chinensis L.plants grown in the arched shed was studied.Three irrigation water treatments were set up in the experiment,well water with conductivity of 3.3 mS/cm(E_(1)),well water with conductivity of 1.9 mS/cm(E_(2)),rainwater conductivity of 0.3 mS/cm(E_(3)).The results showed that the seedling densities of E_(3)and E_(2)treatments were 140 plants/m^(2)and 122.7 plants/m^(2),which were significantly higher than those of E_(1)treatment.Compared with E_(1),E_(2)and E_(3)treatments significantly increased the yield,yield per plant and fresh root weight of Brassica chinensis L..The increases were 5360%~10892%,260%~460%,and 333%~516%.The fresh weight increased by 5360%~10892%,260%~460%,and 333%-516%,respectively.Compared with E_(1)treatment,E_(2)and E_(3)treatments significantly increased the leaf size of Brassica chinensis L..Therefore,in this study area,irrigation water with high conductivity will affect the growth of Brassica chinensis L..
