摘要
采用多层潮汐灌溉设备,研究不同潮汐灌溉高度对多层岩棉基质栽培叶用莴苣(生菜)生长、产量和品质的影响。结果表明:灌溉高度为2 cm时,生菜的叶片数最多,地上部干质量和单个设备产量显著高于其他处理,VC、可溶性蛋白和叶绿素含量最高;灌溉高度为3 cm时,生菜的株高显著高于其他处理;灌溉高度为4 cm时,生菜的硝态氮含量最低。综合来看,在灌溉间隔时间1 h,灌溉维持时间3 min的试验条件下,灌溉高度为2 cm时生菜综合品质最优,产量最高。
This experiment adopted multilayer ebb and flow irrigation equipment,and studied the effects ofdifferent ebb and flow irrigation height in rock wool on growth,yield and quality of lettuce in multilayer cultivation.The results showed that when the irrigation height was2cm,lettuce had the largest number of leaf blades,andthe dry weight overgoroun and single plant yield were significantly higher than that of the other treatments.Thecontents of VC,soluble protein and chlorophyll were the highest.When the irrigation height was3cm,the plantheight were significantly higher than that of the other treatment.When the irrigation height was4cm,the nitratenitrogen content was the lowest.In conclusion,when the experimental conditions were as following:irrigationinterval time was1h,hold time was3min and irrigation height was2cm,the comprehensive quality of lettucewas the best,and its yield was the highest.
