| 摘 要： | 比较分析了DFT和NFT条件下樱桃番茄叶水势变化特征及其水培系统中营养液液温的日变化。结果表明,DFT条件下樱桃番茄叶水势相对较高,且日变化平缓。在早春气候条件下,DFT系统中营养液液温昼夜大部分时间高于NFT系统,对环境中气象因子变化的响应程度较弱。因此,在栽培樱桃番茄时,DFT水培方式要优于NFT。

| Abstract: | The effects of different hydroponic system on variation character of leaf water potential of cherry tomato and diurnal temperature variation nutrient solution were studied. The results showed that the leaf water potential of cherry tomato under DFT was higher than that under NFT. And the diurnal variation of leaf water potential of cherry tomato under DFT was slower than that under NFT. In sunny day of early spring ,most time of the day the temperature of nutrient solution is higher than that in NFT. So the DFT hydroponic system was advantage over NFT system in cherry tomato cultivation. |
