AI Technical Summary

Technical Problem

Existing substrates for industrialized radish seedling production suffer from poor water retention, difficulty in balancing air permeability and water retention, and insufficient root-substrate contact area, leading to severe nutrient solution loss and low production efficiency.

Method used

The radish factory-produced seedling tray substrate is composed of decomposed mushroom residue, expanded rice husks, gorgon fruit shells, perlite, phosphoric acid activated coconut coir, and Bacillus subtilis liquid. The phosphoric acid activated coconut coir forms a porous network structure, which, combined with biological homogenization technology, enhances the dynamic balance of water and air and biological activity.

Benefits of technology

The system optimizes the dynamic balance of water and air, reduces the frequency of water replenishment and nutrient loss, and improves the production efficiency and yield of radish seedlings.

Abstract

The invention relates to the technical field of soilless culture seedling raising substrates, in particular to a radish factory-like hole tray substrate and a preparation method and application thereof. The invention relates to a radish factory-like hole tray substrate, which is prepared from the following raw materials in parts by volume: 30 to 50 parts of decomposed mushroom residues, 30 to 40 parts of expanded rice husks, 20 to 30 parts of gordon euryale seed shells, 10 to 15 parts of perlite, 10 to 15 parts of vermiculite, 20 to 30 parts of phosphoric acid activated coco coir and 2 to 4 parts of bacillus subtilis liquid. The invention provides a radish factory-like hole tray substrate. Agricultural waste resource utilization (composted mushroom residues, gordon euryale seed shells and expanded rice hulls), structural functionalization regulation and control (phosphoric acid activated coco coir is subjected to acid treatment and fiber microfibrillation to form a porous reticulate carrier, and a rigid framework is constructed in cooperation with 1-3mm perlite) and a biological activity synergistic technology (bacillus subtilis liquid is atomized and sprayed) are creatively integrated; and collaborative improvement of resources, structures and biological efficiency is realized.
