6. applying controllable CO₂Growth chamber regulates and controls CO₂The method of concentration, it is characterised in that this method follows these steps to realize:

One, dry ice is placed in dry ice chest (5), is opened intake valve (8), is opened heating plate (6), the dry ice gas in dry ice chest (5) Change and conveys CO into incubator (1)₂, the fan (2) in incubator (1) is opened by CO₂It mixes with air；

Two, pass through CO₂Concentration inductor (3) measures the CO in incubator (1)₂Concentration, with the CO shown on control panel (4)₂ The raising of concentration gradually decreases the revolving speed of fan (2) and the heating temperature of heating plate (6), until the CO in incubator (1)₂It is dense Degree reaches experiment setting value, closes fan (2), heating plate (6) and intake valve (8), completes CO₂CO in growth chamber₂Concentration Regulation.

Technical field

The present invention relates to a kind of CO₂The controllable growth chamber of concentration and its application.

Background technique

With to high CO₂The further investigation for influencing crop production possesses a controllable high CO for numerous laboratories₂ Growing environment is an important problem.FACE experiment is to create a simulation CO₂Increased micro- domain ecological environment carries out CO₂It is increased Simulation test, FACE system is most common CO at present₂Increased micro- domain environmental system, but FACE system not only cost It is very high, and its liquid carbon dioxide used is explosive during transportation, it is very dangerous.It is more portable therefore, it is necessary to one And economical and practical CO₂Control system.

Summary of the invention

The invention solves existing growth chamber, structure is complicated, problem at high cost, and provides a kind of controllable CO₂It plants Object grows case and its application.

The controllable CO of the present invention₂Growth chamber includes incubator, fan, two CO₂Concentration inductor, control panel, dry ice Case, heating plate and air inlet pipe are each provided with a CO on two opposite chamber interior walls of incubator₂Concentration inductor, culture It is provided with fan in the middle part of the case top of case, is provided with control panel on the external box wall of incubator；

Dry ice chest is located in heating plate, and dry ice is placed in dry ice chest, and one end of air inlet pipe and the air inlet of incubator connect Logical, the other end of air inlet pipe is connected with dry ice chest, is provided with intake valve on the air inlet of incubator.

Fan of the present invention, CO₂Concentration inductor and heating plate are connected with control panel by control line.

The present invention applies controllable CO₂Growth chamber regulates and controls CO₂The method of concentration follows these steps to realize:

One, dry ice is placed in dry ice chest, opens intake valve, opens heating plate, and the dry ice in dry ice chest gasifies to culture CO is conveyed in case₂, the fan in incubator is opened by CO₂It mixes with air；

Two, pass through CO₂CO in concentration sensor measurement incubator₂Concentration, with the CO shown on control panel₂Concentration Raising, gradually decrease the revolving speed of fan and the heating temperature of heating plate, until incubator in CO₂Concentration reaches experiment setting Value closes fan, heating plate and intake valve, completes CO₂CO in growth chamber₂The regulation of concentration.

The controllable CO of the present invention₂Growth chamber includes incubator, control panel, dry ice chest and heating plate, and structure is simple, at This is low.Plant growth chamber interior wall has two opposite CO₂Concentration inductor, case top center are furnished with a fan.On control panel (incubator can be shown including a transparent glass visual windows (observable incubator implants growing state) and a display screen Interior temperature, humidity and CO₂Concentration), dry ice chest is connect with incubator by a snorkel, and heating plate is placed under dry ice chest.Make Used time is according to CO₂Concentration needs, and opens intake valve, starts heating plate, dry ice in dry ice chest is gasificated into CO₂, by air inlet pipe into Enter in incubator, as CO in case₂Concentration reaches requirement, closes fan, heating plate and intake valve, makes CO in case₂Concentration maintains institute Under the conditions of needing.This CO₂Incubator is removable, can be used for interior, or configuration external connection battery produces CO for open air₂Dry ice it is easy , and CO₂Concentration control precisely, facilitates operation.
