Effects of Substrate Composition and Ratio on the Growth of Blumea balsamifera Seedlings
To explore the optimal substrate composition and ratio for the growth of Blumea balsamifera L.DC.seedlings,with loess,peat soil,perlite,and coconut bran as the raw materials,the effects of the substrate ratio on the growth,root growth,and chlorophyll content of Blumea balsamifera plants,and the effects of different substrate ratios on the survival rate,seedling growth,root growth,and chlorophyll content were studied.The membership function value of the growth index was compre-hensively evaluated.The results showed significant differences in the effects of different substrate compositions and ratios on seedling growth.The survival rate,plant height,stem diameter,plant dry weight,seedling strength index,prime root length,and average root length of the plants in the T10 treatment were significantly greater than those in the other treatments,and the optimal matrix components were loess,perlite,and coconut bran.The second-best substrate compositions were T3(loess,peat soil,perlite)and T4(loess,peat soil,coconut bran),and the treatment with only loess as the substrate resulted in the worst growth of seedlings.Under pot planting conditions,the optimal substrate ratio of the seedlings was loess:perlite:coconut bran = 46:27:27.
