Eggplant soilless seedling cultivation substrate and preparing method thereof

The invention discloses an eggplant soilless seedling cultivation substrate and a preparing method thereof, and belongs to the technical field of agricultural production. The preparing method of the seedling cultivation substrate mainly comprises the steps of stacking and fermenting bagasse, coconut coir and fowl manure for compost maturity respectively, and then mixing the bagasse, the coconut coir and the fowl manure evenly according to a volume ratio of (5-7):(4-2):1. The seedling cultivation substrate is stable in property, rich in nutrition and suitable for the growth of the eggplant in a seedling stage, so that the eggplant seedling has a developed root system, a stocky seedling stem and a high survival rate after being transplanted. The organic ingredients in the seedling cultivation substrate mainly come from waste of agricultural and husbandry production in a local hot area, including the bagasse, the coconut coir and the fowl manure, so as to replace non-renewable resource grass carbon which is wide
