Seedling culture medium

The invention relates to a seedling culture medium. The seedling culture medium is prepared from, by weight, 75%-80% of coco coir with the pH value of 5.5 to 6.5 and 20%-25% of carrageenan filter residues with the pH value of 6 to 7. The electric conductivity of the coco coir is not larger than 0.5 ds / m. The carrageenan filter residues are prepared from, by weight, 50-60 parts of perlite, 20-30 parts of alga residues and 10-20 parts of mineral substances. The seedling culture medium has the advantages that the coco coir and the carrageenan filter residues are mixed and can achieve the good complementary effect, the mixed seedling culture medium has good water absorption, air permeability and water binding capacity, rotting of the root system of a plant can be avoided, and growth of the root system of the plant can be promoted; the alga active substances and the mineral substances are contained in the carrageenan filter residues, so that it is guaranteed that the product can provide rich nutritional ingredients for the plant and can stimulate the activity of the root system of the plant, drought resistance, waterlogging resistance, cold resistance and disease resistance are enhanced, and the seedling culture medium can be directly used as the seedling culture medium for vegetables and flowers and can also be used as the leaf vegetable culture medium.
