摘　　要：研究了日光温室有机基质栽培番茄盛果期的光合特性。试验结果表明,有机生态型栽培与土壤栽培番茄功能叶净光合速率在10:00～16:00差异显著;叶片光合速率日变化均呈单峰曲线,没有午休现象,峰值均出现在12:00左右,净光合速率最高值分别为12.00μmol·m-2·s-1和9.04μmol·m-2·s-1。The LCi portable photosynthesis system was used to study the photosynthetic characteristics of the Eco-organic Type Culture tomato at flourishing fruit in greenhouse. The result showed that the differences of net photosynthetic rate between the Eco-organic type culture tomato and soil culture tomato was distinct （P〈0.05） from 10：00 am to 16：00 pm; the curve of photosynthetic daily variation of the upper position leaves had one peaks, without midday depression in tomato leaf in greenhouse. The peak occurred at about 12：00 am, the net photosynthetic rate was 12.00 μmol·m^-2·s^-1 and 9.04 μmol · m^-2 ·S^-1
