Medicated residue-based water-retaining slow-release soil modifier, preparation method and application thereof
By using the core-shell structure of the water-retaining and slow-release soil conditioner based on medicinal residue, combined with the humus-resin interpenetrating network and the chitosan-diatomite coating layer, the problem of single function and insufficient water and fertilizer retention in arid soils during the resource utilization of medicinal residue is solved, achieving a highly efficient soil improvement effect.

AI Technical Summary
Existing technologies for the resource utilization of medicinal residues are limited in function and cannot simultaneously solve the problems of poor soil water retention capacity and severe nutrient loss. Furthermore, soils in arid regions lack water and fertilizer retention capacity, and existing technologies cannot effectively integrate water retention, slow nutrient release, and organic matter replenishment functions.
The water-retaining and slow-release soil conditioner based on medicinal residue is used. It consists of core-shell structured particles composed of decomposed medicinal residue powder, superabsorbent resin, sodium bentonite, biochar, slow-release compound fertilizer, chitosan and diatomite, forming a humus-resin interpenetrating network and a chitosan-diatomite coating layer, achieving a synergistic effect of multiple functions.
It significantly improves the soil's water retention and nutrient slow-release capacity, increases fertilizer utilization, and improves soil structure and aeration, making it suitable for dryland agriculture and soil improvement in arid and semi-arid regions.
