摘　　要：利用封闭式循环供液高架栽培系统,研究了栽培槽大小(横切面宽度×深度:20cm×10cm,20cm×15cm,20cm×20cm)和钵栽(直径12cm×高10cm,基质容积1L)对架式栽培番茄(3穗果摘心)生长发育、水肥利用及产量品质的影响。结果表明:与钵栽相比,槽栽促进番茄植株生长,增加产量,但开花和采收时间延迟,果实品质下降,水肥利用效率降低;随着栽培槽体积的增大,植株生长旺盛,干物质积累量增加,但水肥利用效率降低,果实品质下降,不同大小栽培槽处理间水分利用效率和单株产量差异不显著。综合产量、品质及水肥利用效率等指标,番茄架式栽培槽大小以20cm×10cm为宜。The effects of cultured trough size（transection width×depth is 20 cm×10 cm,20 cm×15 cm,20cm×20 cm）and pot volume（diameter 12 cm,height 10 cm,volume 1 L）on plant growth and development,waterand fertilizer uptake and use,yields and quality of elevated cultivation of tomato（Lycopersicon esculentum Mill.）were studied with the elevated closed-cycle cultivation system.The results showed that compared with pot culture,trough culture promoted tomato growth,increased production,but the flowering and harvest times were delayed,the fruit quality and water and nutrients use efficiency were decreased.There were no obvious difference in tomatoyield between different cultured trough sizes,but the plant growth and dry matter accumulation increased,while thewater and nutrients use efficiency and fruit quality were declined.Comprehensively considering the indexes of yield,quality,water and nutrients use efficiency,20 cm×10 cm was an ideal trough size desired by tomato cultivation.
