Substrate for gardening cultivation and preparation method thereof

The invention discloses a horticultural cultivation substrate and a preparation method thereof, and relates to the technical field of cultivation substrates. The invention relates to a turf-free horticultural cultivation substrate prepared from modified fly ash, mushroom dregs, vermiculite, sodium humate, perlite, wormcast and a water-retaining agent. The proportion of the modified fly ash in the matrix is as high as 50-65%, and the use amount of the fly ash is remarkably increased. The cost of the culture medium is reduced, the use requirements of gardening culture can be met, and the hardening phenomenon cannot occur in the planting process. 本发明公开了一种园艺栽培用基质及其制备方法，涉及栽培基质技术领域。本发明是利用改性粉煤灰与菌渣、蛭石、腐殖酸钠、珍珠岩、蚯蚓粪、保水剂制成一种无草炭园艺栽培用基质。本发明基质中改性粉煤灰占比高达50～65％，显著提高了粉煤灰的用量。本发明降低了栽培基质的成本，且能够满足园艺栽培使用需求，种植过程中不会出现板结现象。
