Potting nutrient soil

[0016] A potting nutrient soil, its raw material composition and weight ratio are as follows: 50 parts of coniferous soil, 10 parts of chitosan, 5 parts of grass ash, 5 parts of pine bark, 1 part of old lime, 10 parts of vermicompost, 5 parts of river sand , 5 parts of bone meal, 2 parts of photosynthetic bacteria, 0.5 parts of licorice, and 4 parts of organic fertilizer.

[0017] The grass ash in the present invention is the grass ash with an organic matter content of 30%, and contains a large amount of natural organic substances of plant residues, humus and minerals that have not been completely decomposed.

[0018] In the present invention, the pine bark is the dry pine bark material that has been steamed or baked and sterilized.

[0020] A potting nutrient soil, its raw material composition and weight ratio are as follows: 60 parts of coniferous soil, 15 parts of chitosan, 7.5 parts of grass ash, 7.5 parts of pine bark, 2 parts of old lime, 15 parts of vermicompost, 7.5 parts of river sand , 10 parts of bone meal, 3.5 parts of photosynthetic bacteria, gram-positive actinomycetes, lactic acid bacteria, and yeast flora, and 0.85 parts of licorice.

[0021] The grass ash in the present invention is the grass ash with an organic matter content of 35%, and contains a large amount of natural organic substances of plant residues, humus and minerals that have not been completely decomposed.

[0022] In the present invention, the pine bark is the dry pine bark material that has been steamed or baked and sterilized.

[0023] This embodiment is the best implementation mode.

[0025] A kind of nutrient soil for potting, its raw material composition and weight ratio are as follows: 70 parts of coniferous soil, 20 parts of chitosan, 10 parts of grass ash, 10 parts of pine bark, 3 parts of old lime, 20 parts of vermicompost, 10 parts of river sand , 15 parts of bone meal, 5 parts of photosynthetic bacteria and Gram-positive actinomycetes, 1.2 parts of licorice, and 6 parts of organic fertilizer.

[0026] The grass ash in the present invention is the grass ash with an organic matter content of 40%, and contains a large amount of natural organic substances of plant residues, humus and minerals that have not been completely decomposed.

[0027] In the present invention, the pine bark is the dry pine bark material that has been steamed or baked and sterilized.
