Embodiment 1
[0037] Measure 30 parts by volume of coconut peat, 15 parts by volume of edible mushroom residue, 20 parts by volume of peat, 5 parts by volume of mountain sand, 12 parts by volume of vermiculite and 25 parts by volume of zeolite. The raw materials are all sieved by particle size, and the organic materials are pre-treated by air drying. After mixing the above ingredients, put them in a blender and mix well. The measurement results show that the pH of the matrix product of this formula is 7.1-7.4, the EC is 0.98-1.23mS / cm, the water content is 35-43%, the organic matter content is 41-55%, and the dry bulk density is 0.74-0.84Mg / m 3 , wet bulk density 1.02-1.17Mg / m 3 , the total nutrient content is 3.73-4.59%.
[0038] The matrix product of this formula is used in the planting simulation experiment of vertical greening landscape, and the measurement result shows that the total nitrogen loss of this formula product is far lower than that of general soil (yellow brown soil in Sh...
Embodiment 2
[0040] 25 parts by volume of coconut peat, 20 parts by volume of edible mushroom residue, 18 parts by volume of peat, 8 parts by volume of mountain sand, 5 parts by volume of vermiculite, and 30 parts by volume of zeolite. The raw materials are all sieved by particle size, and the organic materials are pre-treated by air drying. After mixing the above ingredients, put them in a blender and mix well. The measurement results show that the matrix product has a pH of 6.7-6.9, an E of 1.12-1.39mS / cm, a water content of 33-42%, an organic matter content of 47-59%, and a dry bulk density of 0.77-0.85Mg / m 3 , wet bulk density 0.98-1.21Mg / m 3 , the total nutrient content is 4.16-4.77%.
[0041]The matrix product of this formula is used in the planting simulation experiment of vertical greening landscape, and the measurement result shows that the total nitrogen loss of this formula product is far lower than that of general soil (yellow brown soil in Shanghai area) in 7 days, see ima...
