Embodiment 1

[0026] Matrix preparation:

[0027] (1) Preparation of urea-formaldehyde foam particles. The urea-formaldehyde foam (commercially available product) is crushed into uniform particles with a diameter of about 5 mm.

[0028] (2) Preparation of probiotic powder. Bacillus cereus was continuously cultured in a fermenter at 37°C for 16 hours until the O.D600 value of the bacteria was greater than 1.5. Then use a low-temperature high-speed centrifuge to centrifuge at 4000rpm for 1 hour at 2°C to separate the bacteria from the medium, and make the bacillus that has been centrifuged to make a sludge, and finally use a continuous low-temperature drying equipment to make the sludge into an active plant probiotic bacteria powder.

[0029] The composition of the Bacillus cereus culture medium is, by mass percentage, glucose 1.0%, ammonium sulfate 0.2%, dipotassium hydrogen phosphate 0.3%, magnesium sulfate 0.02%, calcium chloride 0.01%, and the balance is water; pH7.2 .

[0030] (3) The...

Embodiment 2

[0036] (1) Preparation of urea-formaldehyde foam particles. The urea-formaldehyde foam (commercially available product) was crushed into uniform particles with a diameter of about 8 mm.

[0037] (2) Preparation of probiotic powder. Bacillus megaterium was continuously cultured in LB medium in a fermenter at 37°C for 16 hours until the O.D600 value of the bacteria was greater than 1.5. Then use a low-temperature high-speed centrifuge to centrifuge at 4000rpm for 1 hour at 2°C to separate the bacteria from the culture medium, and make the bacteria sludge from the Bacillus megaterium precipitated by centrifugation, and finally make the bacteria sludge into active plants through continuous low-temperature drying equipment Probiotic powder.

[0038] (3) The binder is composed of 7g of high molecular weight potassium polyacrylate, 0.5kg of agar powder (both commercially available products) and 1kg of 425# Portland cement.

[0039] (4) The water retaining agent is a mixture of 6g of...

Embodiment 3

[0044] (1) Preparation of urea-formaldehyde foam particles. The urea-formaldehyde foam (commercially available product) was crushed into uniform particles with a diameter of about 3 mm.

[0045] (2) Preparation of probiotic powder: Bacillus cereus and Bacillus megaterium were fermented and cultured in their respective culture media, and cultured continuously at 37°C for 16 hours until the O.D600 value of the bacteria was greater than 1.5. Finally, use a low-temperature high-speed centrifuge at 4000rpm at 2°C for 1 hour to separate the bacteria from the culture medium, and make the bacteria sludge from the centrifuged Bacillus cereus and Bacillus megaterium, and finally separate the bacteria by continuous low-temperature drying equipment. The mud is pulverized, and the pulverized Bacillus cereus and Bacillus megaterium powder are mixed in a mass ratio of 2:1, and set aside.

[0046] (3) The adhesive is composed of 9g high molecular weight potassium polyacrylate, 0.5kg agar powd...

Abstract

The invention relates to the field of water and soil conservation, in particular to a growth and cultivation matrix used for the ecological remediation and a preparation method thereof. Every 1500kg of matrix comprises 30-40kg of urea formaldehyde foam particle, 60-70kg of peat soil, 20kg of organic matter, 0.5-1kg of probiotics powder, 5-10g of water-retaining agent, 5-10g of adhesive, 0.5-1g of plant growth conditioning agent and 3.203kg of trace element. The growth and cultivation matrix disclosed by the invention is favorable for remediating, improving and stabilizing bare rock and ecological fragility areas as well as other environment bad for plants to grow, and especially has an obvious remediation action on slopes, elevations and bare rock surfaces bad for the plants to grow. Meanwhile, the growth and cultivation matrix is favorable for a remediated surface to quickly form a self-supply microecosystem, and the whole curing condition and cost can be lowered.

Description

technical field [0001] The invention relates to the field of water and soil conservation, in particular to a growth cultivation substrate for ecological restoration and a preparation method thereof. Background technique [0002] In the process of engineering construction in recent years, a large number of excavated mountains and rocks have resulted in many broken zones of exposed mountain gaps, which have extremely adverse effects on the urban landscape and the natural environment. Highway construction and mine (stone) mining are modern projects at the cost of destroying the ecological environment. The excavation of road cuttings and filling of embankments all lead to the destruction of native vegetation, the destruction of animal habitats, water and soil erosion, and the emergence of a large number of stones. There are a series of ecological environmental problems such as slopes and exposed mountains, so it is imperative to restore and rebuild the natural ecological vegetat...
