摘　　要：在日光温室条件下,采用封闭式循环供液高架钵栽系统,以‘齐达利’和‘洛美’番茄为试材,研究了不同营养液供应频率(连续供液、间隔15 min供液、间隔30 min供液)对番茄生长发育、生理代谢、产量品质及水肥利用效率的影响。结果表明:与连续供液相比,间歇供液(间隔15 min供液、间隔30 min供液)番茄的长势、光合速率和根系活力显著增强;在间歇供液条件下,‘齐达利’的产量比连续供液分别增加6.33%和5.53%,‘洛美’的产量分别增加10.27%和7.96%;与间隔15 min供液相比,间隔30 min供液提高了果实中可溶性糖、可溶性蛋白和番茄红素含量,改善了果实品质。综合长势、光合特性、产量和品质等指标,间隔30 min供液可作为番茄钵栽的适宜供液频次。Taking tomato varieties Qidali and Luomei as materials,the effects of different fertigation frequencies of nutrient solution,continuous fertigation,intermittent fertigation for 15 min /15 min and intermittent fertigation for 30 min /30 min,on growth and development,physiological metabolism,yield and quality and water and fertilizer use efficiency of tomato were studied using the closed circulating fluid for elevated pot culture system in solar greenhouse. The results showed that compared with continuous fertigation,the plant growth,photosynthetic rate,root activity of intermittent fertigation for 15 min /15 min and 30 min /30 min significantly increased. The yield of Qidali increased by 6. 33% and 5. 53%,and that of Luomei increased by10. 27% and 7. 96% respectively. Compared with intermittent fertigation for 15 min /15 min,the contents of soluble sugar,soluble protein and lycopene in treatment of intermittent fertigation for 30 min /30 min significantly improved. The indicators,plant growth,photosynthetic rate,yield and quality,showed that intermittentfertigation for 30 min /30 min was the optimum frequency for tomato cultured in pod.
