The invention discloses an activating additive suitable for plant-grown cement-soil ecological restoration substrates, a preparation method and application thereof. The method comprises: 1) mixing the culture substrate containing arbuscular mycorrhizal fungus active matter, humic acid, calcium phosphate, urea, vermiculite, kaolin, and red loam according to the mass ratio; 2) mixing Bacillus subtilis and cellulose Decompose the bacteria agent powder to make a suspension and spray it into the above mixture; 3) Add trace element powder, plant growth regulator, and binder to the above mixture in sequence according to the proportion, stir evenly, and let it dry naturally; 5) All the resulting mixture can be sieved. The invention organically combines the culture substrate containing arbuscular mycorrhizal fungus active matter with other materials, and the actual operation is simple, and the application of this technology can reconcile the alkalinity of the plant-grown cement-soil ecological restoration substrate, which helps to improve the plant-grown cement-soil The physical and chemical properties of the ecological restoration substrate can regulate the growth and development of the restoration plant species and improve the ecological restoration effect of the substrate. |
