Abstract

Abstract:

This study was based on three-year old Dendrobium officinale Kimura as the material to explore the effects on the growth, flowering characteristics, and polysaccharide content of Dendrobium officinale Kimura after applying three kinds of organic fertilizers. The aim was to screen out suitable base fertilizers for organic cultivation of Dendrobium officinale Kimura and provide fertilizer application basis for its organic cultivation. The results showed that applying 160 kg of Jinfu Yinong bio-organic fertilizer could significantly promote the germination of new buds, elongation of stems, and increase polysaccharide content of Dendrobium. Baitai microbial fertilizer was beneficial for the growth of Dendrobium leaves. Compared with the first two, the effect of Dahan rutom MIX 1 on promoting the growth of Dendrobium officinale was not significant.

Key words: Dendrobium officinale, organic fertilizer, organic cultivation, yield, quality
