Layering culture substrate applicable living leaf vegetable sales mode

Abstract

The invention relates to the technical field of plant culture, in particular to a layering culture substrate applicable to a living leaf vegetable sales mode. The substrate includes three layers: the lower layer is porcelain granules; the middle layer is a mixture obtained through sufficiently and uniformly mixing worm excretion substrates, rice chaff ash and bio-organic fertilizers; the upper layer is perlite. The substrate has the advantages that the total thickness of the substrate is only 3cm; a seedling disc, with the depth being 3.5cm, widely used for the sprouting vegetable production on the market at present can be used; the additional customization of the seedling disc is not needed; the weight is light, wherein the main reason of the light weight is that the volume weight of the upper layer perlite and the lower layer porcelain granules is very low; the volume weight of the whole substrate is effectively reduced; the transportation and the sales are convenient; the middle layer substrate contains sufficient mineral nutrition necessary for the vegetable growth; fast-growing leaf vegetables such as green vegetables, three-colored amaranth, swamp cabbage and lettuce can be enabled to grow for one month without additional fertilization; the surface of the substrate is clean; the substrate is suitable for appearing in occasions of dining tables and the like.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a layered cultivation substrate suitable for the sales mode of living leafy vegetables.
