【摘要】 利用草炭、醋渣、细砂和蛭石等物料,混合固体无机肥和消毒有机肥,配制成不同配方,进行生菜无土基质栽培试验。结果表明,不同配方的基质材料其理化性状差异明显,对生菜的生长发育、产量和品质具有显著影响。以草炭:醋渣:细砂:蛭石=0.6:1:1:0.6,添加消毒有机肥,定植后追施无机化肥,清水灌溉的栽培模式较好,可推荐用于蔬菜生产。更多还原

【Abstract】 Turf,fine sand,vermiculite and the waste of vinegar produced were used to make soilless cultivated substrates,added disinfectant organic fertilizers and chemical fertilizers for lettuce planting.The result indicated that the physical and chemical properties of different substrates had great differences.The lettuce could be grown rapidly,got high yield with good qualities by substrate cultivation compared with normal soil culture.更多还原
