摘要
以草炭、蛭石、炉渣、废菇料和粉碎后的玉米秸秆为原料,按不同材料种类及比例混合制成8种蔬菜无土栽培复合基质,测定并比较了8种复合基质的理化性质,初步筛选出适宜蔬菜栽培的优良基质。结果表明:8种基质的容重、pH值和总孔隙度均在蔬菜栽培的适宜范围内;大小孔隙比、基质电导率及成本上各有优劣。通过综合考量,初步优选出的无土栽培基质为基质Ⅳ(V棉籽皮∶V炉渣=1∶1)、基质Ⅵ(V棉籽皮∶V蛭石=1∶1)和基质Ⅶ(V玉米秸秆∶V棉籽皮∶V蛭石=1∶1∶2)。
Eight kinds of vegetable soilless culture substrates were prepared using different peat,vermiculite,slag,mushroom residue and corn stalk with different proportion,the physicochemical properties of these substrates were analyzed,and the substrates that were suitable for vegetable were selected.The results showed that the bulk density,pH value and total porosity of these substrates were suitable for vegetable,while the void ratio,conductivity and cost of each substrate had its own advantages and disadvantages.Through the comprehensive consideration,the Substrates Ⅳ,Ⅵ and Ⅶ were better.
