Abstract:

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
