Example Embodiment

[0036] Example 1

[0037] Measure 30 parts by volume of coconut bran, 15 parts by volume of edible mushroom residue, 20 parts by volume of grass charcoal, 5 parts by volume of mountain sand, 12 parts by volume of vermiculite, and 25 parts by volume of zeolite. The raw materials are sieved through particle size, and the organic materials are pre-treated by air-drying. After mixing the above materials, put them in a mixer and mix them thoroughly. The measurement results show that the pH of the matrix product of this formula is 7.1-7.4, EC is 0.98-1.23mS / cm, water content is 35-43%, organic matter content is 41-55%, and 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 simulation experiment of vertical greening landscape planting. The measurement results show that the total nitrogen loss of this formula product in 7 days is much lower than that of ordinary soil ...

[0039] Example 2

[0040] Measure 25 parts by volume of coconut bran, 20 parts by volume of edible mushroom residue, 18 parts by volume of grass charcoal, 8 parts by volume of mountain sand, 5 parts by volume of vermiculite, and 30 parts by volume of zeolite. The raw materials are sieved through particle size, and the organic materials are pre-treated by air-drying. After mixing the above materials, put them in a mixer and mix them thoroughly. The measurement results show that the pH of the matrix product is 6.7-6.9, E is 1.12-1.39mS / cm, water content is 33-42%, organic matter content is 47-59%, and dry bulk density is 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 simulation experiment of vertical greening landscape planting. The measurement results show that the total nitrogen loss of this formula product in 7 days is much lower than that of ordinary soil (yellow brown soil...

Abstract

The invention provides a soil-fixing fertility type matrix suitable for vertical green walls. The soil-fixing fertility type matrix is prepared from 25-40 volume parts of coco coir, 5-20 volume parts of turf, 10-20 volume parts of edible mushroom residues, 5-15 volume parts of mountain sand, 5-15 volume parts of vermiculite and 15-35 volume parts of zeolite. Ideally, the pH is 5.5-7.8, the EC is less than 3mS/cm, the water content is 30-50%, the content of organic matter is greater than 25%, the dry bulk density is 0.4-0.85Mg/m<3>, the wet bulk density is 0.65-1.25Mg/m<3>, and the total nutrient content is 2-5%. The invention also provides a method for preparing the soil-fixing fertility type matrix suitable for vertical green walls. The matrix has water-retaining property and fertilizer-retaining property, has the advantages of high nutrient content, low maintenance and slow nutrient loss, is suitable for urban vertical green walls and roof greening and plays an active role in improving urban ecological environment quality.

Description

[0001] Technical field: [0002] The invention relates to the field of agriculture, in particular to fertilizer technology, in particular to vertical greening of indoor and outdoor facades of urban buildings and other structures and special fertilizers thereof, specifically to a soil-fixing and fertility-type substrate suitable for vertical green walls and its preparation method. [0003] Background technique: [0004] 1. Vertical greening (vertical greening) refers to a kind of greening that uses suitable green plants and adopts certain cultivation methods (usually planting boxes or planting bags) to make plants cover various buildings (structures) and other structural facades. form. Vertical greening is a main form of three-dimensional greening and a useful supplement to urban greening. In today's highly urbanized and densely populated areas, land resources are already in short supply, which squeezes the space available for greening. Vertical greening, through the planting ...
