Embodiment 1

[0013] A seedling raising substrate is composed of the following components in weight percentage: 75% of coconut peat with a pH of 5.5, 25% of carrageenan filter residue with a pH of 7, and the electric conductivity of the coconut peat is 0.4ds / m.

[0014] The carrageenan filter residue includes 50 parts by weight of perlite, 30 parts by weight of seaweed residue, and 20 parts by weight of minerals. The diameter of the perlite is 1.5 mm, and the diameter of the coconut peat is 5 mm.

Embodiment 2

[0016] A seedling-raising matrix is ​​composed of the following components in weight percentage: 77.5% of coconut bran with a pH of 6, 22.5% of carrageenan filter residue with a pH of 6.5, and the electric conductivity of the coconut bran is 0.45ds / m.

[0017] The carrageenan filter residue includes 55 parts by weight of perlite, 25 parts by weight of seaweed residue, and 15 parts by weight of minerals. The diameter of the perlite is 2 mm, and the diameter of the coconut peat is 6.5 mm.

Embodiment 3

[0019] A seedling raising substrate is composed of the following components in weight percentage: 80% of coconut bran with a pH of 6.5, 20% of carrageenan filter residue with a pH of 6, and the electric conductivity of the coconut bran is 0.5ds / m.

[0020] The carrageenan filter residue includes 60 parts by weight of perlite, 20 parts by weight of seaweed residue, and 10 parts by weight of minerals. The diameter of the perlite is 2.5 mm, and the diameter of the coconut peat is 8 mm.

[0021] 1. Coconut peat is degraded and released slowly, so that the pH of coconut peat is between 5.5 and 6.5, and the conductivity is below 0.5ds / m;

[0022] 2. The carrageenan filter residue is degraded and released slowly, so that the pH of the carrageenan filter residue is between 6 and 7;

[0023] 3. Mix the coco peat treated in step 1 with the carrageenan residue treated in step 2, and mix evenly by stirring.

[0024] Through the mixing of coconut peat and carrageenan filter residue, cocon...

Abstract

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.

Description

technical field [0001] The invention relates to a seedling raising substrate. Background technique [0002] Nowadays, whether it is to produce vegetables or flower seedlings, the seedling substrate is the key factor for the production of high-quality products. When selecting the seedling substrate, the following factors need to be considered. From the perspective of the ecological environment, it should be considered that the seedling substrate does not contain live bacteria, insect eggs and Hazardous substances, nutritional conditions and growth environment Considering the water retention of the seedling substrate and the characteristics that are conducive to root winding, it should be mainly composed of inorganic and organic composite substrates, while the existing seedling substrates basically use carbonized rice husks and cottonseeds in consideration of cost factors. Shells, sawdust, vermiculite, perlite, etc., and the mixed seedling substrate can not achieve the best ef...
