Strawberry seedling substrate and preparation method thereof

The invention belongs to the technical field of strawberry cultivation. The invention discloses a strawberry seedling substrate and a preparation method thereof. The mixed fermentation substrate obtained after mixed fermentation of the pectin sludge and the straw powder is compounded with the earthworm fertilizer substrate, the garden waste substrate, the fly ash, the walnut green seedcase extract, the chitosan, the edible fungus residue powder and the like, and then the mixture is mixed with the modified urea-formaldehyde resin to prepare the seedling culture substrate which is wide in source and low in cost; the strawberry seedling culture medium contains rich organic matters and other trace elements, can well regulate the acid-base property of the seedling culture medium, and is very suitable for growth and development of strawberry seedlings. 本发明属于草莓栽培技术领域。本发明公开了一种草莓育苗基质及其制备方法。本发明将果胶污泥和秸秆粉混合发酵后的混合发酵基质与、蚯蚓肥基质、园林废弃物基质、粉煤灰、核桃青皮提取物、壳聚糖、食用菌菌渣粉等进行复配后再混合改性脲醛树脂制备的育苗基质来源广泛，成本低，而且含有丰富的有机质以及其它微量元素，能够很好的调节育苗基质的酸碱性，很适
