Abstract

The bulk density of the four cultivated substrates prepared in the experiment varied between 0.42 and 0.57 g/cm3, they all belong to light cultivation substrate. The pH was between 7.38 and 7.95, when the peat: wormcast: vermiculite: mushroom dreg fertilizer was 0.5:0.5:2:1, it is the lowest and neutral, and the CE value satisfied the requirements of plant cultivation. In 4 kinds of cultivation substrates, the contents of total and available nitrogen, phosphorus and potassium were abundant, and the contents of organic matter were high. When the peat: wormcast: vermiculite: mushroom dreg fertilizer was0.5:0.5:2:1, the rosa plant height is the highest, there was no significant difference in the content of nitrogen and chlorophyll in the leaves of rosa. According to the comprehensive indexes, the cultivation substrate of peat: wormcast: vermiculite: mushroom dreg fertilizer of 0.5:0.5:2:1 is most suitable for the growth of rosa.
