Effects of different substrate formulations on the growth and ornamental quality of Primula merrilliana
摘要
Abstract
Primula merrilliana,an endemic species in China belonging to the genus Primula(Primulaceae),possesses ornamental value and ecological significance.To screen suitable substrate types and optimal ratios for its growth,this study used seedlings of P.merrilliana as experimental materials.Four cultivation substrates(pine needles,peat,humus soil and coir)were individually mixed with perlite or vermiculite in varying proportions,resulting in a total of 36 substrate formulations.The physicochemical properties of each substrate formulation were determined,and their comprehensive effects on plant growth indices,physiological indices and flowering indices were systematically compared.Principal component analysis(PCA)was further applied to comprehensively evaluate the cultivation performance of different substrates.The results showed that among the four tested substrates,the pine needle-based substrate exhibited the best overall performance.Under substrate formulation A6(Vpine needles∶Vvermiculite=2∶1),the plants achieved maximum values in height(11.47 cm),crown width(23.07 cm)and leaf width(2.23 cm).Meanwhile,the number of leaves,chlorophyll content,and aboveground dry weight were also relatively high.Furthermore,the flowering period lasted for 105 days,with 71 scapes and a total of 312 flowers,and the flower diameter was 1.40 cm,demonstrating the best overall ornamental quality.Principal component analysis results further confirmed that plants grown in substrate formulation A6 achieved the best comprehensive performance.The findings provide theoretical guidance and technical support for the low-cost,high-efficiency cultivation of P.merrilliana.关键词
