氮、磷、钾、锌、硼肥配施对黄山贡菊产量和品质的影响

Effects of Nitrogen, Phosphorus,Potassium and Micronutrient Fertilizers on the Yield and Quality of Huangshan Gongju

盆栽试验结果表明,N肥仍是黄山贡菊产量的首要限制因子,施N处理和不施N处理之间产量差异达显著或极显著水平。增施P肥对产量的影响不明显。N、P、K肥配合施用及在此基础上增施Zn肥和B肥可促进贡菊的生长发育,提高贡菊产量与品质。P肥对菊花粗蛋白、总黄酮和绿源酸的含量影响最大,实际生产中可根据对产量和品质的不同需求调节P肥用量。N、P、K肥配施可促进菊花对Fe、Zn、Mn等矿质营养元素的吸收。

Pot experiment results showed that N fertilizer was still the primary limited factor of the yield for Huangshan Gongju. The yield differences between the treatments with and without N fertilizer were significant. P fertilizer hadn＇t obvious effect on the yield. Applied B and Zn fertilizers on the basis of the combined application of nitrogen, phosphorous and potassium fertilizers could improve growth, yield and quality of Huangshan Gongju, promote the absorption of Fe,Zn and Mn. P fertilizer made great effects on the contents of total flavonoid, chlorogenic acid and crude protein.
