摘要

PURPOSE: Provided is a method for making cultivation earth for plants, which reutilizes waste concrete and waste wood materials to give fermented compost and thus to facilitate the cultivation of plants. CONSTITUTION: The method for making cultivation earth for plants comprises the steps of: cutting waste wood materials to a size up to 30 cm; dipping the cut wood into water containing 10-15 wt% of nitrogen component based on the weight of the cut wood to perform fermentation for 2-7 days; crushing the fermented wood to a size of 1-2 mm; further fermenting at 60% of humidity and 40-50 deg.C of temperature for 15-30 days to obtain fermented compost. In the method, 55-76% of the fermented compost is mixed with 10-15% of N, 5-10% of P, 5-10 % of K, 2-5% of Mg and 2-5% of Ca, and then mixed with recycled sand in an amount of 2-3 times of the volume of the mixture.
