| 摘 要： | 研究了钼对盆栽小白菜叶绿素、抗坏血酸含量以及硝酸盐累积的影响。试验分为3组,对照组(CK),未施钼;试验1组(Mo1)施钼0.15mg/kg;试验2组(Mo2)施钼0.30mg/kg。盆栽3周后对小白菜取样,分别测定其硝酸盐、叶绿素和抗坏血酸的含量。结果表明,随着施钼量的增加,小白菜中硝酸盐的含量显著降低,叶绿素显著增加,且各组间差异极显著(p<0.01)。与CK相比,施钼后小白菜中抗坏血酸含量的增加幅度更大,其中Mo1组和Mo2组与对照组间差异极显著(p<0.01),而Mo1组和Mo2组之间差异显著(p<0.05)。钼可以显著改善小白菜的品质,有效防止其硝酸盐的累积。 |

| Abstract: | Effects of Molybdenum on content of chlorophyll and ascorbic acid and nitrate accumulation in pakchoi cultured in pot were studied. Molybdenum(Mo)was applied at the rate of 0(CK),0.15 mg·kg-1(Mo1)and 0.30 mg·kg-1(Mo2)to an acid yellow-brown soil. Pakchoi was cut to analysis the content of chlorophyll, ascorbic acid and nitrate after 3 weeks. The results showed that the accumulation of nitrate decreased sharply with the Mo level raise, and the difference about 3 groups was significantly(p<0.01). Content of chlorophyll increased remarkably and the difference was significantly(p<0.01). Content of ascorbic acid changed at large range. The difference between Mo groups and CK(p<0.01),and Mo1 and Mo2(p<0.05)were significantly higher. It was suggested the quality of pakchoi was improved and nitrate accumulation was controlled effectively applied Mo. |
