Vegetable hole tray seedling raising substrate and seedling raising method

The invention relates to the field of vegetable culture, particularly a vegetable hole tray seedling raising substrate and a seedling raising method. The seedling raising substrate is composed of 1/3 of turfy soil, 1/3 of furnace slag and 1/3 of vermiculite. The composite formula substrate provided by the invention has the advantages of light volume weight, high water and fertilizer retentivity and high permeability, and achieves the goals of proper physical and chemical properties, abundant resources and low cost. Six vegetables, such as cucumbers, tomatoes, chilies, cabbages and the like, which are cultured by the composite formula substrate, have more developed root systems and stronger seedlings than the vegetables cultured by other formula substrates. 本发明涉及蔬菜栽培领域，具体地涉及蔬菜穴盘育苗基质以及育苗方法。所述育苗基质由草炭土、炉渣、蛭石组成，其中，草炭土、炉渣、蛭石各占1/3。根据本发明的复合配方基质的容重轻，且持水保肥能力强，通透性强，达到了理化性状适宜、资源丰富、成本低的目的。该复合配方基质的培养下黄瓜、番茄、辣椒、甘兰等6种蔬菜根系比其他配方基质更发达，幼苗更健壮。
