采用"3414"不完全正交回归设计,利用盆栽试验研究金盏菊氮磷钾肥施用效果,并筛选适宜的肥料配方。结果表明,氮肥和磷肥对金盏菊的营养生长和生殖生长均有较大影响,而钾肥效果主要表现在生长后期。氮、磷间有明显的正交互作用。以金盏菊总花数、功能叶片数、株高、植株干样质量为目标,进行统计分析,得出盆栽(每盆装基质2 kg)金盏菊氮(N)、磷(P2O5)、钾(K2O)的最佳施用量为0.4、0.2和0.3 g·kg-1

关键词: 金盏菊, 氮磷钾, 肥效, 肥料配比


Effect of N, P and K fertilization on Calenduld officinalis L. growth and suitable fertilizer formula of NPK nutrients ratio for the flower was carried out through pot experiment with "3414" incomplete regression-orthogonal design. Our results showed that the N and P played important role in vegetative and reproductive growth. The effect of K was mainly reflected in late growth stage. There is a obvious positive interactions of N and P. Regarding total flowers, functional leavers, plant height and dry weight as the target, it was showed that the recommended fertilizer amount of N, P2O5 and K2O for pot application were 0.4, 0.2 and 0.3 g·kg-1 (each pot filled with 2 kg substrate) .

Key words: Calenduld officinalis L., N, P and K fertilizer, Fertilizer efficiency, Fertilizer ratio
