Abstract
The invention discloses a method for preparing a soilless culture substrate based on municipal solid waste. The method comprises the following steps that organic materials obtained by sorting the solid waste are ground to the materials with the particle size smaller than 5 cm, the organic materials and edible mushroom residues are put in a fermentation tank to be evenly mixed at the room temperature, the water content and the carbon nitrogen ratio of the whole system are regulated, the mixture is ground, overturned and thrown, then air is injected into the fermentation tank, fermentation is carried out for 35-45 days at 50-70 DEG C to reach a decomposed state, and the mixture is naturally cooled to the room temperature; the obtained mixture and a porous material are compounded at the volume ratio of 1:(0.5-2), and the compounded mixture and rear earths are mixed evenly. According to the method, the solid waste serves as the raw materials to ferment the soilless culture substrate through the fermentation tank, and thus the resource utilization of the waste is achieved; meanwhile, the temperature controllability in the production process is good, the fermentation time can be remarkably shortened by regulating the proper water content and the proper carbon nitrogen ratio, and the absorbing rate of nutrient media can be increased.
Description
Technical field
The invention belongs to field of Environment Protection, relate in particular to a kind of method preparing soilless culture substrate based on domestic waste.
Background technology
Be rich in a large amount of organic materialss in domestic waste, conduct oneself well if improper and put, easily environment is produced and pollute and cause the wasting of resources.By the biodegradable organic materials separated in domestic waste is carried out fermented manure, can not only be used for soil improvement provides the fertilizer of nutrient for crop, can also reduce the Pollution risk to environment.Soilless culture is a kind of novel planting type, carry out the cultivating method of irrigating with matrix or nutritive medium without natural soil, the important content of facilities horticulture and the principal mode of garden crop factorial praluction are now become, widespread use in flower culture in recent years.Compared with traditional soil cultivation, there is water-saving, province is fertile, laborsaving, Crops production and quality can be improved, avoid soil continuous cropping obstacle, and not by advantages such as regional condition restrictions.
Substrate culture is a kind of mode that in soilless culture, popularizing area is maximum, modern agriculture being in great demand to matrix, and it is fixed in the matrix of organic or inorganic by the root system of crop, by the method for drip irrigation or trickle irrigation, and supply crop alimentary liquid.In the organic matter material of current use, great majority directly can not carry out arviculture as matrix, and needing to become thoroughly decomposed by fermentation could be used for crop culture to a certain extent., in prior art, adopt the method for artificial simple composting to ferment, easily material fermentation non-uniform phenomenon occurs, utilize the organism in domestic refuse to prepare a kind of access expansion and the nutraceutical matrix of vegetables High-efficient Production can be promoted.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of method preparing soilless culture substrate based on domestic waste.
The object of the invention is to be achieved by following technical proposals.
Prepare a method for soilless culture substrate based on domestic waste, carry out according to following step:
Step 1, the organic materials gone out by sorting consumer waste is crushed to its particle diameter and is less than 5cm, at room temperature, described organic materials and edible fungi residues are put into fermenter Homogeneous phase mixing, regulate the water content of whole system to 50-60wt%, carbon-nitrogen mass ratio is to (25-30): 1, and wherein, the volume ratio of organic materials and edible fungi residues is (2-3): 1;
Step 2, carries out pulverizing to step 1 gained mixture and turns over throwing, pulverizes after turning over throwing, in fermenter, is filled with air, ferments 35-45 days to the state of becoming thoroughly decomposed, be then naturally down to room temperature at 50-70 DEG C;
Step 3, presses 1:(0.5-2 by step 2 gained mixture and porous materials) volume ratio composite, namely the mixture after composite and rare earth Homogeneous phase mixing are obtained soilless culture substrate, wherein, 1m
3mixture add the rare earth of 5 ~ 10g.
In technique scheme, in described step 1, regulate the carbon-nitrogen mass ratio of whole system for (25-30) with urea: 1.
In technique scheme, in described step 1, the volume ratio of organic materials and edible fungi residues is 7:3
In technique scheme, in described step 2, with turnover throwing machine, pulverizing is carried out to mixture and turn over throwing.
In technique scheme, in described step 2, ferment 40-45 days to the state of becoming thoroughly decomposed at 65-70 DEG C, be then naturally down to room temperature.
In technique scheme, in described step 3, by the mixture after composite and rare earth Homogeneous phase mixing in mixing and blending machine.
In technique scheme, described porous materials is from haydite, perlite, vermiculite or rock wool.
Beneficial effect of the present invention is: the present invention take domestic refuse as prepared using fermenter fermentation soilless culture substrate, achieve the recycling of rubbish, production process temperature control is good simultaneously, regulate applicable water ratio and carbon-nitrogen ratio significantly can shorten fermentation time, improve the specific absorption of nutraceutical matrix.
Embodiment
Below the method preparing soilless culture substrate based on domestic waste of the present invention is described in detail.
Prepare a method for soilless culture substrate based on domestic waste, carry out according to following step:
Step 1, take domestic refuse as raw material, sub-electing metal wherein, plastics, masonry, dregs etc. can not after the composition of decomposition, organic materials sorting consumer waste being gone out to be easy to decomposition is crushed to its particle diameter and is less than 5cm, at room temperature, described organic materials and edible fungi residues is put into fermenter Homogeneous phase mixing, regulate the water content to 55% of whole system, regulate carbon-nitrogen mass ratio to 26:1 with urea, wherein, the volume ratio of organic materials and edible fungi residues is 7:3;
Step 2, carries out pulverizing with turnover throwing machine to step 1 gained mixture and turns over throwing, pulverizes after turning over throwing, in fermenter, is filled with air, ferments 42 days to the state of becoming thoroughly decomposed, be then naturally down to room temperature at 65-70 DEG C;
Step 3, by composite for the volume ratio that step 2 gained mixture and porous materials press 1:1.5, this porous materials is from haydite, perlite, vermiculite or rock wool.Namely mixture after composite and rare earth Homogeneous phase mixing in mixing and blending machine are obtained soilless culture substrate, wherein, 1m
