| 中文摘要: |
| 通过在栽培过程中监测营养液的pH 值以及EC 值变化情况研究营养液的3 种更换频率，10 d，F10，
20 d，F20，30 d，F30对小白菜产量和品质的影响。结果表明与F10 相比F20，F30 处理在叶片数、株高及叶绿素含
量等指标上无显著差异，地上部鲜重，根鲜重和干重略有降低。但无显著差异维生素C 的含量升高硝酸盐的含量
显著降低，且F30 处理好于F20 处理生产上选择30 d更换1次营养液，不降低小白菜产量改善品质。 |
| 英文摘要: |
| Through monitoring the pH and EC (electrical conductivity), three renewal frequenciesF10,F20,F30and
their influences on the yield and quality of Chinese cabbage in soilless culture were conducted in this research: The results
showed that no significant variation existed among F30, F20 and F10 treatments in terms of leaf number and plant height,
stem diameter, shoot fresh weight, root fresh weight, dry weight and other morphological characters as well as contents of
chlorophyll. Compared with F10, vitamin C content of F20 and F30 treatments increased, and content of nitrate decreased
significantly, and the effect of F30 treatment was better than F20 treatment. |
