Special container seedling growing substrate for leaf vegetables

Abstract

The invention discloses a special container seedling growing substrate for leaf vegetables. The special container seedling growing substrate comprises, by volume, 20-40% of peat, 5-10% of expanded perlite, 15-20% of vermiculite, 5-10% of stove ash residues, 5-15% of sawdust, 22-40% of tea residues and earthworm casts, 0.5-2% of long-acting compound slow-release fertilizers, 0.5-2% of water retaining agents and 20-40% of waste mushroom bran. The special container seedling growing substrate has the advantages that raw materials for the special container seedling growing substrate can come from wide sources and are easily available, and accordingly the special container seedling growing substrate is low in production cost; the waste mushroom bran is organic agricultural waste, is high in quantity and can be used for producing soilless culture substrates, accordingly, environmental pollution can be reduced, waste can be turned into wealth, harm can be turned into benefits, and the special container seedling growing substrate can be widely used for growing seedlings of leaf vegetable crops such as brassica chinensis, purple brassica chinensis and different types of lettuces.

Description
