Description
Technical field
The present invention relates to greenhouse gardening technology fields, and in particular to a kind of film filtering increases the side of carbon dioxide in greenhouse
Method.
Background technique
The current greenhouse quantity in China is increasing, 500,000,000,000 yuan of annual value of production or so, and 80% output value from the winter, the spring,
Autumn, but this three season due to the needs of heat preservation, so that greenhouse is in closed state, cause air in canopy opposite with outside air
Barrier, carbon dioxide cannot be supplemented timely.After sunrise, with the photosynthetic acceleration of vegetables, gas concentration lwevel in canopy
Sharply decline, is down to carbon dioxide compensation point (0.008%---0.01%) sometimes hereinafter, vegetable crop can hardly carry out just
Normal photosynthesis affects the growth and development of vegetables, causes disease and the underproduction.
In order to supplement carbon dioxide, common method has vegetable grower in the prior art: being generated using strong acid and carbonate reaction
Carbon dioxide, the methods of fuel combustion increase the concentration of carbon dioxide in greenhouse.But above method is at high cost, inconvenient for use,
Neatly gas concentration lwevel can not be made to increase.
Summary of the invention
It is a kind of at low cost, easy to use the purpose of the present invention is aiming at the shortcomings in the prior art, providing, can flexibly it increase
The method of greenhouse gas concentration lwevel.
The purpose of the present invention is achieved through the following technical solutions: a method of increasing greenhouse gas concentration lwevel, passes through
The mode of stalk fermentation pond and membrane separation device is set to increase carbon dioxide, specifically includes following methods:
Method one: being arranged fermentation vat in greenhouse, carbon dioxide is generated when using fermentation as daily supplies；
Method two: gas concentration lwevel cannot reach requirement in greenhouse, and starting membrane separation device generates carbon dioxide from air
As supplement.
Method two specifically: carbon dioxide concentration detecting device and controller, gas concentration lwevel inspection are set in greenhouse
It surveys gas concentration lwevel information in device detection greenhouse and is transferred to controller, gas concentration lwevel information is transferred to control
Device, when gas concentration lwevel cannot reach requirement in greenhouse, controller control starting membrane separation device isolates two from air
Carbonoxide；After carbon dioxide concentration detecting device detects that gas concentration lwevel restores normal in greenhouse, then carbon dioxide is dense
Degree information is transferred to controller, and membrane separation device is closed in controller control.
For CO2 separation method mainly have chemical absorption method, Physical Absorption method, pressure swing adsorption method, condensation at low temperature and
Membrane separation process.Membrane separation process is the energy-efficient CO quickly grown in the world today2Isolation technics, has that equipment is simple, accounts for
Ground area is small, easy to operate, separative efficiency is high, low energy consumption, environmental-friendly and be convenient for and the advantages that other methods are integrated.Membrane material
It is the core of membrane separation technique, currently preferred membrane material is by three-dimensional polyethylene glycol oxide cross-linked network and the high ether of low molecular weight
The polyethylene glycol oxide derived molecules chain of oxygen content is interspersed to be constituted.
Method one specifically:
Step 1: digging pit in greenhouse, cheats interior laying waterproof cloth；
Step 2: it is placed to fermentation materials fractional layer, and sprinkles decomposing agent on every layer of fermentation materials surface layer；
Step 3: watering, then fermented with the waterproof cloth covering for having aperture, generate carbon dioxide.
Preferably, membrane separation device of the invention is a comprehensive device, can not only isolate carbon dioxide, may be used also
To isolate oxygen, the oxygen isolated supplies oxygen fermentation vat.
Fermentation materials in step 2 are divided into 5 layers from the bottom up:
First layer is that weight ratio is (20-30): (15-20): (2-5): (1-3): (1-3): the stalk of (2-5), cow dung, pond
Pool bed mud, rice chaff, mushroom slag, greenhouse abandoned vegetable mix；

Pressure fan is equipped in the fermentation vat, carbon dioxide is conveyed to the vegetables of greenhouse by air-supply band by pressure fan.
Exhaust blower is set in greenhouse, exhaust blower is connected with controller, when gas concentration lwevel is excessively high in greenhouse, controller
Control starting exhaust blower carries out air draft.
Material in method one after fermenting tank for fermentation can be used for the plantation of big shed vegetable；Membrane separation device in method two
Also may separate out nitrogen, the booth vegetable for having gathered in it is fresh-keeping.The present invention makes full use of natural resources, no
The concentration of greenhouse carbon dioxide is only effectively increased, and the fertilising of vegetables and fresh-keeping can be used for, is an organic whole, has
Significant economic benefit and social benefit.
Beneficial effects of the present invention: the present invention increases dioxy by way of setting stalk fermentation pond and membrane separation device
Change carbon, carbon dioxide is generated when fermentation as daily supplies, meets the primary demand of carbon dioxide in greenhouse, when burst feelings occur
When gas concentration lwevel cannot reach requirement in condition greenhouse, starting membrane separation device generates carbon dioxide as benefit from air
It fills, it is easy to use, it can flexibly increase greenhouse carbon dioxide as needed.Further, the material after fermenting tank for fermentation can be used
In the plantation of big shed vegetable, membrane separation device also may separate out nitrogen, the booth vegetable for having gathered in it is fresh-keeping.This hair
It is bright that natural resources is made full use of, the concentration of greenhouse carbon dioxide is not only effectively increased, but also vegetables can be used for
