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。
The results of pot experiment showed that N fertilizer was still the primary limiting factor for the yield of Huangshan Gongju, and the yield difference between N and N treatments was significant or extremely significant. The effect of applying P fertilizer on yield was not obvious. The combination of N, P and K fertilizers and the application of Zn fertilizer and B fertilizer on this basis can promote the growth and development of Gongju and increase the yield and quality of Gongju. P fertilizer on Chrysanthemum crude protein, total flavonoids and chlorogenic acid content of the greatest impact on the actual production can be based on the different needs of yield and quality regulation P fertilizer. N, P and K fertilizers promoted the absorption of mineral nutrients such as Fe, Zn and Mn in chrysanthemum.
