Abstract:

In order to explore the effects of different water and fertilizer treatments on the ornamental quality of Phalaenopsis aphrodite, this study used Sanseniao as the experimental variety and applied water-soluble fertilizers commonly used in Phalaenopsis aphrodite production. Five different water and fertilizer treatment combinations were set up to screen for the optimal fertilization method that promotes the flowering quality and root vitality of Phalaenopsis aphrodite. The results showed that there was varying degrees of correlation between the 12 ornamental traits of Phalaenopsis aphrodite. Through principal component analysis, three principal components were extracted with contribution rates of 52.590%, 28.364%, and 11.071%, respectively, with a cumulative contribution rate of 92.025%; In the F2 treatment (Huaduoduo 1+Genniu 700× solution), the comprehensive evaluation value (D value) and ranking of flowering related indicators of Phalaenopsis aphrodite were the highest, and its comprehensive flowering quality was the highest which indicated that the Genniu amino acid water-soluble fertilizer has the strongest positive effect on promoting flowering plant growth of Phalaenopsis aphrodite. This study has guiding significance for selection of fertilizer and fertilization methods in Phalaenopsis aphrodite production.
