Manufacturing method of facility agriculture three-dimensional hydroponic degradable environment-friendly planting carrier

The invention discloses a method for manufacturing a degradable environment-friendly planting carrier for three-dimensional water culture in facility agriculture, which comprises the following steps of: uniformly mixing bamboo charcoal powder and cassava starch according to a set weight ratio to form a compound material, uniformly mixing polyether polyol and isocyanate according to a set weight ratio to form a compound adhesive, and uniformly mixing the compound material and the compound glue according to a set weight ratio, injecting the mixture into a mold, and carrying out foaming molding to obtain the required degradable environment-friendly planting carrier. The method is easy and convenient to operate and free of any toxic and harmful substances, the manufactured planting carrier has good water absorption and water retention characteristics, the rooting speed of hydroponic plants and the carrier utilization rate are increased, meanwhile, the planting carrier has the environment-friendly and degradable c
