摘　　要：以番茄品种"金鹏1号"为试材,设3个水平红蓝光质配比R/B=7∶1、R/B=3∶1、R/B=1∶1,2种营养液分别为山崎番茄配方和霍格兰番茄配方,以气候箱处理为对照。用波长为660nm红色LED光源和450nm蓝色LED光源,研究不同红蓝光质配比和营养液耦合下番茄生长的差异,探索人工可控条件下适宜番茄生长的光质配比和营养液组合。结果表明:霍格兰营养液各处理随红光比例增加,株高、茎粗、干鲜重有增大的趋势;气候箱对照各光合色素含量较高;红蓝光处理可以显著增大潜在光化学活性(Fv/Fo)和最大光能转化效率(Fv/Fm);霍格兰营养液,R/B=7∶1处理光合速率较高。综上所述,采用霍格兰营养液,R/B=7∶1时有助于番茄苗期株高以及生物量的增加,是适宜番茄苗期生长的较优组合。‘Jinpeng No.1＇was selected as test materials,under three light levels,R/B=7∶1,R/B=3∶1R/B=1∶1and two kinds of nutrient solutions,Yamasaki and Hoagland were carried out.The control groups were treated in climate chamber.The 660nm-wavelength red LED and 450nm-wavelength blue LED were adopted as the light sources to explore the difference of tomato seedlings＇ growth,yield and quality respectively under circumstances proportioned with different light and nutrient solutions,thus to find out an appropriate match of light quality and nutrient solution for growing highquality tomatoes under artificial controlled environment.The results showed that with Hoagland,the plant height,stem diameter and dry fresh weight ascended as the ratio of red light increasing.The contents of photosynthetic pigment in the climate chamber were relatively higher;red and blue light treatment could notably built up Fv/Fo and Fv/Fm;seedlings gained higher photosynthetic rate under light level R/B=7∶1with Hoagland.A conclusion could be drawn from the foregoing analyses,Hoagland nutrient solution combining R/B=7∶1light level was a better match for improving the quality of tomato seedlings and its fruits under artificial controlled environment.
