活力素对菠菜产量及硝酸盐含量的影响

Effect of Huolisu on yield and nitrate content of spinach

利用微区试验研究了不同氮磷钾配比条件下,喷施活力素对菠菜产量及硝酸盐含量的影响。结果表明:氮磷钾配合施用能显著提高菠菜产量,并能提高硝酸还原酶活性、降低硝酸盐含量。在单施氮肥条件下,喷施活力素有明显的增产效果;喷施活力素也明显提高了硝酸还原酶活性,降低了硝酸盐和亚硝酸盐含量,改善了菠菜的食用品质。

By means of minispot experiments,the effects of Huolisu on yield and nitrate content of spinach was studied under different ratio of nitrogen to phosphorus and potassium .The results showed that the balanced application of nitrogen,phosphorus and potassium could increase the yield of spinach significantly,increased the nitrate reductase activity,and decreased nitrate content.The application of Huolisu increased spinach yield under the condition of only applying nitrogen;and the application of Huolisu increased the nitrate reductase activity,decreased the content of nitrate and nitrite .It is favorite to improve the quality of spinach.
