番茄简易营养液膜栽培的产量和品质均比稻谷壳灰基质栽培有较大的改善。番茄生长中的耗水量与株间温度和池温的相关性分别达到０．０１和０．０５的显著水平。ＮＦＴ栽培床的进水口和出水口产量存在显著差异（０．０５），但在４０ｃｍ和８０ｃｍ宽度的栽培床之间的产量并没有差异。同时本文还对番茄开花结果初期营养液中的矿质元素浓度的昼夜变化进行了研究。
The yield and quality of tomato simple liquid culture were significantly improved compared with that of rice hull medium. The correlation between the water consumption in tomato growth and the inter-plant temperature and pool temperature reached significant levels of 0.01 and 0.05, respectively. There was a significant difference (0.05) in yield at the inlet and outlet of NFT cultivation beds, but there was no difference in yield between cultivation beds of 40 cm and 80 cm width. At the same time, we also studied the diurnal variation of mineral element concentration in the nutrient solution of early flowering tomato.
