[0069] An embodiment of the present application provides a method for regulating the photosynthetic efficiency of oat leaves. The execution subject of the method for regulating the photosynthetic efficiency of oat leaves includes, but is not limited to, at least one of electronic devices such as a server, a terminal, etc. that can be configured to execute the method provided by the embodiment of the present application.

[0070] Refer to Figure 1 As shown, it is a schematic flowchart of the method for regulating the photosynthetic efficiency of oat leaves provided by an embodiment of the present invention. In this embodiment, the method for regulating the photosynthetic efficiency of oat leaves includes:

[0071] S1. Receive an oat photosynthetic efficiency regulation instruction, start the light emission simulator pre-installed in the oat crop test chamber, and regularly change the light radiation intensity value of the light emission simulator within a preset interval to obtain a set of light radiation intensity values.

[0072] Specifically, referring to Figure 2 As shown, the regularly changing the light radiation intensity value of the light emission simulator within a preset interval to obtain a set of light radiation intensity values includes:

[0073] S11. Set the change interval of the light radiation density intensity value of the light emission simulator to 0 - 1800 W / m 2 ;

[0074] S12. Obtain a total of 19 light radiation density intensity values within the change interval of the light radiation density intensity value at an increment of 100 W / m 2 ;

[0075] S13. Call the following model to calculate the light radiation intensity values corresponding to the set of 19 light radiation density intensity values to obtain a set of light radiation intensity values:

[0076] P = 5.5493E SR + 3.6570

[0077] where P is the light radiation intensity value, and E SR is the light radiation density intensity value, with a total of 19 values.

[0078] It should be noted that the light emission simulator pre-installed in the oat crop test chamber simulates the change of natural sunlight intensity by changing the emitted light radiation density intensity value. The preset change interval of the light radiation density intensity value in the embodiment of the present invention is [0, 1800 W / m 2 , at an increment of 100 W / m2 The increment can obtain a total of 19 light radiation density intensity values within the change range, namely 0, 100 W / m 2 , 200 W / m 2 , 300 W / m 2 , 400 W / m 2 , 500 W / m 2 , 600 W / m 2 , 700 W / m 2 , 800 W / m 2 , 900 W / m 2 , 1000 W / m 2 , 1100 W / m 2 , 1200 W / m 2 , 1300 W / m 2 , 1400 W / m 2 , 1500 W / m 2 , 1600 W / m 2 , 1700 W / m 2 , 1800 W / m 2 . Using the model P = 5.5493E SR + 3.6570, a total of 19 light radiation density intensity values can be converted into a total of 19 light radiation intensity values. Exemplarily, the light radiation intensity value corresponding to the 100 W / m 2 light radiation density intensity value obtained by model calculation = 100 * 5.5493 + 3.6570 = 558.587 lx.

[0079] S2. Use the CO2 gas sensor and humidity sensor pre-installed in the test chamber to obtain a set of CO2 concentration values and a set of air humidity values corresponding to the set of light radiation intensity values.

[0080] It should be clear that every time the light radiation intensity value is changed, the CO2 gas sensor and humidity sensor pre-installed in the test chamber are used to obtain a CO2 concentration value and an air humidity value once. The set of light radiation intensity values contains a total of 19 specific light radiation intensity values, and each specific light radiation intensity value will correspond to a specific CO2 concentration value and a specific air humidity value. Therefore, the set of CO2 concentration values and the set of air humidity values in the embodiments of the present invention each contain 19 specific CO2 concentration values and 19 specific air humidity values.

[0081] S3. Calculate the volume value of the test chamber, and at the same time use the temperature sensor and barometer pre-installed in the test chamber to obtain the initial temperature value and initial atmospheric pressure value of the test chamber, and based on the set of CO2 concentration values and the set of air humidity values, call a preset model to calculate a set of photosynthetic efficiency values of oat leaves.

[0082] Specifically, referring to Figure 3 as shown, calculating the volume value of the test chamber, and at the same time using the temperature sensor and barometer pre-installed in the test chamber to obtain the initial temperature value and initial atmospheric pressure value of the test chamber, and based on the set of CO2 concentration values and a set of air humidity values, calling a preset model to calculate a set of photosynthetic efficiency values of oat leaves, including:

[0083] S31. Calculate the volume value of the test chamber using the following formula:

[0084] V = L * D * H

[0085] where V is the volume value of the test chamber, L is the length value of the test chamber, D is the width value of the test chamber, and H is the height value of the test chamber;

[0086] S32. Obtain the initial temperature value and initial atmospheric pressure value of the test chamber based on the temperature sensor and barometer pre-installed in the test chamber;

[0087] S33. Set the change time interval of the light radiation intensity value, and calculate the change value of the CO2 concentration value in the test chamber within the change time interval;

[0088] S34. Construct a photosynthetic efficiency calculation model and calculate a set of photosynthetic efficiency values of the oat leaves.

[0089] It should be noted that the photosynthetic efficiency calculation model constructed in the embodiment of the present invention is as follows:

[0090]

[0091] where G is the photosynthetic efficiency value of the oat leaves, V is the volume value of the test chamber, P0 is the initial atmospheric pressure value of the test chamber, W is the air humidity value obtained by the humidity sensor, T0 is the initial temperature value in the test chamber, R is the ideal gas constant, taken as 8.314 J / (mol·K), Δt is the change time interval of the light radiation intensity value, and ΔC is the change value of the CO2 concentration value obtained by the gas sensor in the test chamber within Δt.

[0092] Furthermore, setting the change time interval of the light radiation intensity value of the light emission simulator in the test chamber, and calculating the change value of the CO2 concentration value in the test chamber within the change time interval of the light radiation intensity value, includes:

[0093] Calculate the change value of the CO2 concentration value in the test chamber within the change time interval of the light radiation intensity value using the following formula:

[0094] ΔC = C t - C t-Δt

[0095] wherein, ΔC is the change value of the CO2 concentration value in the test chamber during the time interval of the change in the light radiation intensity value, C t is the CO2 concentration value in the test chamber after the change in the light radiation intensity value, C t-Δt is the CO2 concentration value in the test chamber before the change in the light radiation intensity value, and Δt is the time interval of the change in the light radiation intensity value.

[0096] It should be noted that in the photosynthetic efficiency calculation model, the volume value, the initial temperature value, and the initial atmospheric pressure value of the test chamber are all constant quantities that do not change. Δt is the time interval of the change in the light radiation intensity value. Since the light emission simulator changes the emitted light radiation intensity value at the same time interval, Δt can also be regarded as a constant quantity. W is the air humidity value obtained by the humidity sensor, and there are 19 specific values. ΔC is the change value of the CO2 concentration value obtained by the gas sensor in the test chamber within Δt, and there are also 19 values. Therefore, a set of photosynthetic efficiency values of the oat leaves calculated in the embodiments of the present invention also includes 19 specific values.

[0097] S4. Plot the trend chart of the set of light radiation intensity values and their corresponding set of photosynthetic efficiency values to obtain the light intensity efficiency diagram of oat leaves.

[0098] Specifically, plotting the trend chart of the set of light radiation intensity values and their corresponding photosynthetic efficiency values to obtain the light radiation intensity photosynthetic efficiency diagram of oat leaves includes:

[0099] Construct a rectangular coordinate system including the x-axis and the y-axis, where the value of the x-axis is the set of light radiation intensity values, and the value of the y-axis is the corresponding set of photosynthetic efficiency values;

[0100] Convert the set of light radiation intensity values and their corresponding photosynthetic efficiency values into several coordinate points in the rectangular coordinate system;

[0101] Connect the several coordinate points in the form of a curve to obtain the light radiation intensity photosynthetic efficiency diagram of oat leaves.

[0102] It is clear that the set of light radiation intensity values includes 19 specific light radiation intensity values, which respectively correspond to 19 specific photosynthetic efficiency values calculated. According to the corresponding relationship in the calculation process, a set of light radiation intensity values and a set of photosynthetic efficiency values can be matched as 19 coordinate points in the plane rectangular coordinate system. By understanding the 19 coordinate points with a curve, the trend chart of the set of light radiation intensity values and their corresponding set of photosynthetic efficiency values can be obtained.

[0103] S5. Plot the trend curves of a set of CO2 concentration values and a set of air humidity values corresponding to the set of photosynthetic efficiency values in the oat leaf light intensity efficiency diagram to obtain the oat leaf photosynthetic efficiency diagram.

[0104] The plotting of the trend curves of a set of CO2 concentration values and a set of air humidity values corresponding to the set of photosynthetic efficiency values in the oat leaf light intensity efficiency diagram includes:

[0105] Based on the calculation data of the set of photosynthetic efficiency values, match the set of CO2 concentration values with the set of photosynthetic efficiency values to obtain several concentration-efficiency coordinate values;

[0106] Mark the several concentration-efficiency coordinate values with several solid triangles in the rectangular coordinate system;

[0107] Connect the several solid triangles in the form of a curve to obtain the trend curve of a set of CO2 concentration values corresponding to the set of photosynthetic efficiency values;

[0108] Based on the calculation data of the set of photosynthetic efficiency values, match the set of air humidity values with the set of photosynthetic efficiency values to obtain several humidity-efficiency coordinate values;

[0109] Mark the positions of the several concentration-efficiency coordinate values with several solid squares in the rectangular coordinate system;

[0110] Connect the several solid squares in the form of a curve to obtain the trend curve of a set of air humidity values corresponding to the set of photosynthetic efficiency values.

[0111] It should be understood that calculating each specific photosynthetic efficiency value requires a specific CO2 concentration value and a specific air humidity value. Therefore, 19 photosynthetic efficiency values correspond to 19 specific CO2 concentration values and 19 specific air humidity values. According to the corresponding relationship, convert the photosynthetic efficiency values and CO2 concentration values into 19 concentration-efficiency coordinate values and plot them in the oat leaf light intensity efficiency diagram to obtain the trend curve of a set of CO2 concentration values corresponding to a set of photosynthetic efficiency values. Similarly, according to the corresponding relationship, convert the photosynthetic efficiency values and air humidity values into 19 humidity-efficiency coordinate values and plot them in the oat leaf light intensity efficiency diagram to obtain the trend curve of a set of air humidity values corresponding to a set of photosynthetic efficiency values.

[0112] S6. Obtain the real-time light radiation intensity value of the test chamber based on the pre-installed light radiation sensor in the test chamber, and turn on the pre-installed CO2 supply gas valve and water vapor supply gas valve in the test chamber to adjust the real-time CO2 concentration value and real-time air humidity value in the test chamber to return to the target CO2 concentration value and target air humidity value corresponding to the real-time light radiation intensity value in the photosynthetic efficiency curve of oat leaves, so as to realize the regulation of the photosynthetic efficiency of oat leaves.

[0113] Specifically, the obtaining the real-time light radiation intensity value of the test chamber based on the pre-installed light radiation sensor in the test chamber, and turning on the pre-installed CO2 supply gas valve and water vapor supply gas valve in the test chamber to adjust the real-time CO2 concentration value and real-time air humidity value in the test chamber to return to the target CO2 concentration value and target air humidity value corresponding to the real-time light radiation intensity value in the photosynthetic efficiency curve of oat leaves includes:

[0114] Obtain the real-time light radiation intensity value of the test chamber based on the pre-installed light radiation sensor in the test chamber, and obtain the target CO2 concentration value and target air humidity value corresponding to the real-time light radiation intensity value from the photosynthetic efficiency curve of oat leaves;

[0115] Respectively calculate the differences between the real-time CO2 concentration value and real-time air humidity value collected by the CO2 gas sensor and humidity sensor in the test chamber and the target CO2 concentration value and target air humidity value;

[0116] Judge the positive and negative of the differences. According to the positive and negative results, adjust the CO2 supply concentration and water vapor supply humidity of the CO2 supply gas valve and water vapor supply gas valve, so that the real-time CO2 concentration value and real-time air humidity value in the test chamber return to the target CO2 concentration value and target air humidity value.

[0117] Specifically, the judging the positive and negative of the differences and adjusting the CO2 supply concentration and water vapor supply humidity of the CO2 supply gas valve and water vapor supply gas valve according to the positive and negative results includes:
