摘　　要：以无纺布作栽培基质,设计了一套适用于小型叶菜栽培的水肥一体化轻简栽培系统。以普通白菜品种扬州青1号和高梗白为试材,采用裂区试验设计,研究该栽培模式下不同营养液浓度对普通白菜生长指标和生理指标的影响。结果表明,营养液浓度对普通白菜地上部鲜质量、可溶性糖含量、叶片叶绿素SPAD值均有极显著影响;随着营养液浓度的增加,两个普通白菜品种的地上部鲜质量、可溶性糖含量和叶绿素SPAD值均呈现先增加后降低的趋势,根系丙二醛含量则呈现先降低后升高的趋势;125%全价营养液处理有利于提高普通白菜地上部鲜质量、可溶性糖含量和叶片叶绿素SPAD值,并保持根系较低的丙二醛含量。Integrative water and fertilizer planting system for pakchoi[Brassica campestris L. ssp.chinensis（L.）Makino var. communis Tsen et Lee]was designed using the non-woven fabric as growing media.Taking‘Yangzhouqing No.1＇and‘Gaogengbai＇as material,this experiment studies the effects of different nutrient solution concentrations on growth and physiological indexes of pakchoi by split block design.The results indicate that along with the increase of nutrient solution concentrations,the overground fresh weight,soluble sugar content and chlorophyll SPAD value will firstly increase and then decrease,while the root MDA has an opposite tendency-firstly decrease and then increase.125% full price nutrition solution treatment is in favour of upgrading overground fresh weight,soluble sugar content and chlorophyll SPAD value,and maintaining low root MDA value of pakchoi.
