钼、硼对花椰菜产量及品质的影响

 以花椰菜‘厦雪100天’品种进行的研究表明, 增施2.25 kg·hm ^{- 2}钼酸铵作基肥或叶面喷施0.1%钼酸铵, 可显著提高叶片叶绿素含量和硝酸还原酶活性, 花球硝酸盐含量下降, 维生素C和可溶性糖含量提高, 增产显著; 增施15.00 kg·hm^-2硼砂作基肥或叶面喷施0.1%～0.2%硼砂也可提高产量, 改善品质; 但叶面喷施0.4%硼砂会造成减产和花球品质下降。

Mo and B''''s Effects on the Yield and Quality of Cauliflower

Studies based on the cauliflower variety of‘Xiahue 100 Days’ indicated that, when 2.25 kg·hm^{- 2} (NH₄)₂MoO₄ ·2H₂O was used as base fertilizer or 0.1% (NH₄)₂MoO₄ ·2H₂O sprayed as foliage fertilizer, both the chlorophyll content and nitrate reductase activity of leaves could be increased, meanwhile improve the quality of the cauliflower. 15100 kg·hm^{- 2} B used as base fertilizer or 0.1% - 0.2% Belement used as foliage fertilizer also could increase the yield and improve the quality of the cauliflower. However, high concentration (0.4%) of B would make both the yield and the quality of cauliflower reduced.
