Abstract

Abstract: In the process of planting green plants, cultivation matrixes have important effects on plant growth. Therefore, it is very important to develop a substrate with strong fertilizer supply capacity, pH and EC suitable for the growth of green plants. In this experiment, with Quamoclit pennata as a green plant, five different cultivation matrix formulations using Fluvo-aquic soil, peat and vermiculite were made to study the changes of available nutrients in the growth of Q. pennata in different cultivation matrixes, and the growth conditions and seedling indexes of Q. pennata in different cultivation matrixes were analyzed. The results showed that the cultivation matrix of “Fluvo-aquic soil 50%+peat 30%+vermiculite 20%” and “Fluvo-aquic soil 40%+ peat 60%” had strong and stable ability to supply nitrogen, phosphorus and potassium. The pH and EC were also suitable for the growth of Q. pennata, and the seedling height, stem diameter, dry weight and strong seedling index were all higher. Thus, both of the above two substrates can be used as the cultivation matrixes of Q. pennata.

Key words: Quamoclit pennata, cultivation matrix, pH, available nutrients, EC
