Problems solved by technology

However, the existing CO2 suitable for plant growth in the market 2 There are few varieties of incubators, not only expensive (the price of each better quality is hundreds of thousands of yuan), but also CO 2 The concentration control accuracy is not high (±75ppm), it is difficult to meet some requirements for high accuracy of test processing
Moreover, when the system CO 2 Concentration requirements lower than atmospheric CO 2 concentration when the existing CO 2 The incubator is not possible
In addition, the existing CO 2 The incubator also often has poor plant growth due to insufficient light intensity.

Embodiment Construction

[0021] Figure 1 shows a method that can control CO 2 The plant growth culture device of concentration, comprises sealing and is provided with the plant growth chamber assembly 2 of opening device, three-way transfer valve I 5, the air pump 7 that has outlet pipe 71, CO 2 Gas balance assembly 8, gas buffer tank 10, CO 2 Test assembly 12 and three-way transfer valve II13.

[0022] The sealed plant growth chamber assembly 2 provided with an opening device includes a growth chamber base 21 and a plant growth chamber 22 . The plant growth chamber 22 is a cuboid box with an open bottom (that is, without a bottom), so an opening 221 is formed at the open bottom. Plant growth chamber 22 can be made with 3mm transparent plexiglass plate, and size can be determined according to the size of tested plant. One end of the thermometer 3 passes through the top surface of the plant growth chamber 22 and is located in the inner chamber of the plant growth chamber 22; In order to ensure the ...

Abstract

The present invention discloses a plant growth culture equipment capable of controlling CO2 concentration. It includes a sealed plant growth chamber component with opening device. It is made of transparent material, one end of its outet tube is communicated with the internal cavity of said plant growth chamber component, and its another end is connected with CO2 gas balance component by successively means of three-way switching valve I, tube I, air pump and air outlet tube, the CO2 gas balance component is connected with internal cavity of said plant growth chamber component by successively means of tube II, air buffer tank, tube IV, CO2 detection component, tube III, three-way switching valve II and inlet tube; two ends of connecting tube are respectively connected with three-way switching valve I and three-way switching valve II. The application of said invention can raise accurate control of CO2 concentration.

Description

technical field [0001] The invention relates to a method capable of controlling CO 2 Concentrated plant growth culture device. Background technique [0002] Today, atmospheric CO 2 Global climate change has become the focus of attention due to elevated concentrations of CO 2 The effect of elevated concentration on plant growth has also become a current research hotspot, and the CO 2 Precise control of concentration is the key to carry out research in this area. However, the existing CO2 suitable for plant growth in the market 2 There are few varieties of incubators, not only expensive (the price of each better quality is hundreds of thousands of yuan), but also CO 2 The concentration control accuracy is not high (±75ppm), it is difficult to meet some requirements for high accuracy of test processing. Moreover, when the system CO 2 Concentration requirements lower than atmospheric CO 2 concentration when the existing CO 2 An incubator is out of reach. In addition, t...
