Straw fermentation type flower nutrient soil and preparation method thereof

The invention relates to straw fermentation type flower nutrient soil and a preparation method thereof. The straw fermentation type flower nutrient soil is prepared from the following raw materials in percentage by weight: 30-45 percent of straw yeast, 1-3 percent of a pH modifier, 5-10 percent of nutrient substance, 5-10 percent of biomass charcoal, 0.5-1 percent of bactericide, 0.1-1 percent of a water-retaining agent and 30-45 percent of grass charcoal. The preparation method of the straw fermentation type flower nutrient soil comprises the following steps: mixing the straw yeast and the nutrient substance; adding the biomass charcoal, the bactericide, the water-retaining agent and the pH modifier for modification. The straw fermentation type flower nutrient soil is scientific in formulation, convenient to prepare and wide in application prospect; the growth of flowers cultivated by using the flower nutrient soil is excellent and is obviously superior to that of flowers cultivated by using common soil; moreover, the flowers are free from nutrition loss and pest and disease damage.
