| Abstract: | Using the random arrangement design in the experiment,the Lettuce was used as experimental materials,adopted the way of substrate culture to study the effects of different Potassium element supply levels on the nitrate accumulation.The results showed that: with the concentration of Potassium element increase,nitrate content and activity of Nitrate Reductases decreased continuously in contain range under experimental condition. |
