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.
