锌硼微肥对甘蓝产量和品质的影响

采用叶面喷施锌硼微肥的方法,研究了微量元素锌硼对甘蓝产量与品质的影响。结果表明,喷施锌硼微肥对甘蓝有明显的增产和改善品质的作用。喷施锌硼可明显促进甘蓝植株对氮、磷的吸收,而抑制对钾的吸收;不论是单独喷施还是混合喷施,锌硼都能明显提高甘蓝Vc含量、可溶性糖含量,喷施锌硼微肥对甘蓝的总酸度影响并不明显。

Effects of Zinc and Boron Microelement Fertilizer on Yield and Quality of Cabbage

This experiments in the effects of foliar application of Zinc and Boron microelements fertilizers on cabbage was conducted. Results indicated that foliar applications of Zn and B microelement fertilizers could obviously increase yield and improve quality of cabbage.The effect of the combined application of Zn and B (Zn0.25 B3.50) on cabbage was the best.Its production-increasing ratio had reached to 32.2 %.It was clear the B fertilization had better effect than the Zn fertilization in yield because the production-increasing ratio of B fertilization was 16.1 % higher than Zn fertilization's.Spraying Zn and B could remarkably increase the total nitrogen of plant. The total phosphorus content of the plant was obviously increased because of application of Zn and B.In addition, Zn and B could remarkably inhibit the absorbtion of potassium. With respect to quality,no matter was alone spraying or co-spraying,they all enhanced remarkably the content of Vc and soluble sugar in cabbage.The ranges of Vc and soluble sugar varied between 3.5 %~23.5 %,28.6 %~85.1 % respectively.Meanwhile,there was insignificant difference in total acidity.So the quality of cabbage could be enhanced obviously through spraying appropriate amount of Zn and B elements on leaf.
