| 摘 要： | 采用叶面喷施、根部施用、叶面喷施与根部施用相结合的3种处理方式，研究了钼、锰对不结球
白菜硝酸还原酶活性、硝酸盐含量及营养品质的影响。结果表明，钼能够显著提高不结球白菜的硝酸还
原酶活性，使其硝酸盐含量显著降低；锰对不结球白菜硝酸还原酶活性的影响不明显,但可以显著降低其
硝酸盐含量。钼和锰均可提高不结球白菜可溶性糖和VC含量。与单施钼、锰相比，钼锰配施对降低不结
球白菜硝酸盐含量、提高其可溶性糖和VC含量效果更明显。

| Abstract: | Effect of molybdenum and manganese on nitrate reductase activity,nitrate content
and nutrient quality in Brassica campestris ssp.chinensis were studied using solution
culture by spraying Mo and Mn elements on leaf,root and leaf combined with root
treatment.The results indicated that nitrate reductase activity was significantly improved
by Mo treatment,which caused significant reduction of nitrate content.Although,no
remarkable effect on improving nitrate reductase activity was found by Mn treatment,nitrate
content was also reduced.Both Mo and Mn could improve the contents of soluble sugar and
VC.Compared with single treatment of Mo or Mn,the reduction of nitrate content,improvement
of soluble sugar and VC contents were more distinct by treatment with Mo plus Mn. |
