Description

Technical Field

[0001] The present invention is a high-throughput plant greenhouse gas measurement platform, belonging to the technical field of greenhouse gas emissions. Background Art

[0002] The main driving factor of global climate change lies in the emissions of greenhouse gases (such as carbon dioxide, methane, and nitrous oxide). In the agricultural field, methane (CH4) and nitrous oxide (N2O) are the main sources of greenhouse gases. It is worth noting that the global warming potentials of methane and nitrous oxide per unit mass are about 30 times and 270 times that of carbon dioxide respectively. Therefore, their impact on global climate change is particularly significant. By improving crop cultivation methods and varietal genetic characteristics, greenhouse gas emissions from farmland can be effectively reduced. The technology for measuring the emission rates of these gases is of crucial significance for evaluating farmland carbon sources and sinks. Generally, using plant cultivation pots for detection can significantly increase the sample quantity and detection efficiency compared to direct field operation. The currently widely used methods can generally be divided into two categories: one is field measurement; the other is pot experiment measurement. The former usually involves using a static chamber to enclose a small area and collecting gas samples for analysis, or using a device with a gas duct connected to a gas analyzer for on-line monitoring. Although this method can provide relatively accurate data, due to the limitations of the number of devices and human resources, it can often only cover dozens of sample plots and is difficult to reach a scale of hundreds or even thousands of samples. The latter conducts research on plants planted in containers and also uses a static chamber to enclose the plants and sample to measure their greenhouse gas emission rates. This cylindrical enclosure device needs to be manually placed above the plants and sealed with the soil or water surface. However, this process is complex and time-consuming and laborious, and it is difficult to achieve large-scale and efficient measurement.

[0003] In addition, there is a common problem in the existing technologies - that is, directly comparing the data obtained at different time points. Since the environmental conditions vary greatly within each time period of a day, this will inevitably introduce systematic errors, making it extremely difficult to compare across a large number of samples.

Through the lead screw 52, the nut seat 58 is driven to move left and right. Then, the fixed part of a first driving device with an output shaft connected to the lead screw 52 and electrically connected to the host 3 is installed on the left end of the rack 5. Through the first driving device, the lead screw 52 is driven to rotate. The first driving device can be a first motor 51; The nut seat 58 is connected to the outer end of the lead screw 52 through a rolling nut pair. Through the nut seat 58, an installation carrier is provided for components such as a first lifting device. A round rod 53 located below the lead screw 52 and passing through the nut seat 58 and slidably connected to the nut seat 58 is arranged inside the rack 5. Through the round rod 53, the movement of the nut seat 58 is guided. Then, the fixed part of a first lifting device electrically connected to the host 3 is installed on the lower end of the nut seat 58. Through the first lifting device, the mounting bracket 54 is driven to move up and down. The first lifting device can be a second electric push rod 56. The horizontal part of the mounting bracket 54 with a cross-section in the shape of an L is arranged at the lower end of the movable part of the first lifting device. Through the mounting bracket 54, an installation carrier is provided for the automatic clamp 55. Then, the automatic clamp 55 electrically connected to the host 3 is installed on the front end of the vertical part of the mounting bracket 54. Through the automatic clamp 55, the planting pot is clamped. A first telescopic rod 57 located outside the first lifting device is arranged between the lower end of the nut seat 58 and the mounting bracket 54. Through the first telescopic rod 57, the movement of the mounting bracket 54 is guided; Measurement boxes 4 are installed at the lower ends of the two vertical parts of the rack 5, and the two measurement boxes 4 arranged at the inner bottom of the detection room 2 are arranged opposite to each other. Through the measurement box 4, space is provided for the detection operation. An automatic door 46 electrically connected to the host 3 is installed on the inner end of the measurement box 4. Through the automatic door 46, automatic opening and closing are realized. A placement plate 42 is movably arranged inside the measurement box 4. Through the placement plate 42, the planting pot is lifted. Then, the fixed part of the telescopic device with the movable part connected to the placement plate 42 is installed on the outer end of the measurement box 4. Through the telescopic device, the placement plate 42 is driven to move. The telescopic device can adopt the first electric push rod 41. A suction pipe and a return pipe, both of which are connected to the host 3 at the other ends, are connected and arranged on the outer end of the measurement box 4. The suction pipe and the return pipe are used in cooperation to enable circular flow between the measurement box 4 and the host 3; Four lifting rods 43 are respectively installed at the four corner positions at the lower end of the placement plate 42. The four lifting rods 43 are used in cooperation to lift the placement plate 42. Four rolling members respectively arranged at the inner bottom of the measurement box 4 and connected in a rolling manner are respectively arranged at the lower ends of the four lifting rods 43. The four rolling members are used in cooperation to assist the movement of the placement plate 42. The rolling members can adopt moving wheels 44. A placement groove 45 is formed by recessing downward on the upper end surface of the placement plate 42. Through the placement groove 45, the planting pot is placed in a positioned manner on the placement plate 42.

[0018] Before use, first select a batch of planting pots with plants planted. Then, through the positioning frame 81, a plurality of planting pots are positioned and placed on the cultivation rack 8, and each planting pot is numbered. Thus, a batch of planting pots are sequentially placed on the cultivation rack 8. At the same time, the cultivation racks 8 with the planting pots placed are arranged in an orderly manner in the planting shed 1, so as to ensure that the plants planted on a batch of planting pots grow in an environment with consistent environmental factors such as temperature and humidity; During use, first take out the cultivation rack 8 from the planting shed 1 and carry the cultivation rack 8 into the detection room 2. Then, start the automatic door 46 through the host 3, so that the automatic door 46 opens. Then, start the corresponding first electric push rod 41 through the host 3, and with the assistance of the moving wheels 44, the placement plate 42 moves outwards from the corresponding measurement box 4. Then, start the corresponding first motor 51 through the host 3, so as to drive the lead screw 52 to rotate, and then the nut seat 58 moves along the round rod 53 to a suitable position. Then, start the corresponding second electric push rod 56 through the host 3, so as to drive the mounting frame 54 to move downwards to a suitable position. Then, start the automatic clamp 55 through the host 3, and then clamp the planting pots placed on the cultivation rack 8; Then, the second electric push rod 56 and the mounting bracket 54 are used to lift the clamped planting pot. Then, the first motor 51, the lead screw 52 and the nut seat 58 are used to move the clamped planting pot directly above the placement plate 42. Then, the second electric push rod 56 is used to place the clamped planting pot on the upper end of the placement plate 42, and the automatic fixture 55 releases the clamping of the planting pot. Then, the first motor 51, the lead screw 52, the nut seat 58, the second electric push rod 56 and the mounting bracket 54 are used to return the automatic fixture 55 to its original position. Then, the first electric push rod 41, the four lifting rods 43 and the four moving wheels 44 are used to return the placement plate 42 to the measurement box 4, so that the planting pot is placed in the measurement box 4. Then, the automatic door 46 is closed, so that the measurement box 4 containing the planting pot is in a sealed state; Again, following the above steps, different planting pots on the cultivation rack 8 are respectively placed in different measurement boxes 4. At the same time, the host 3 will detect whether each measurement box 4 contains a planting pot inside. When a planting pot is inside the measurement box 4, it enters the corresponding measurement box 4 and is arranged in the waiting measurement sequence. The host 3 will sequentially detect each measurement box 4 in the waiting measurement sequence; During the detection, after the automatic door 46 is closed, the host 3 and the corresponding suction pipe immediately perform a gas extraction operation on the measurement box 4, and the extracted gas is transported into the host 3 to detect the gas concentration, and the detected data is used as the initial concentration x0. Then, the extracted gas is returned to the measurement box 4 through the return pipe to ensure the air pressure balance inside the measurement box 4 during the measurement process. Then, after waiting for a set time, the measurement box 4 is again subjected to a gas extraction operation to detect the gas concentration. The greenhouse gas emission amount is calculated by comparing the concentration after gas emission with the initial concentration, so as to estimate the emission rate and screen out the planting pots with different emission amounts; The host 3 intelligently arranges the detection sequence by judging the placement order of the planting pots in each measurement box 4, and performs air extraction and gas concentration detection on these measurement boxes 4 according to the set number of air extraction times. After extracting the gas from one measurement box 4 and completing the gas concentration detection, during the waiting time of this measurement box 4, the host 3 will send a signal to continue to extract and detect the gas of other measurement boxes 4, so as to improve the detection efficiency; After the detection is completed, through the analysis of the measurement data, the positions of the planting pots are rearranged and the order of the next measurement is re-planned. Then, the cultivation rack 8 is returned to the planting shed 1 and waits for the next measurement. Then, after a predetermined period of time, the cultivation rack 8 is again transported to the detection room 2 for another detection operation. Following the above steps, multiple measurement operations are carried out, so that the differences between plant samples can be accurately obtained, and the detection of the greenhouse gas emission rate of potted plants with high throughput can be achieved. The sample throughput of the detection can be greatly improved compared with that in the field; By measuring the variation law of the greenhouse gas emission rate of a large number of plant samples throughout the day, a variation curve is obtained, and the model formula of the curve is obtained. Then, using the model formula, the plant emission rate data at different times of the day are corrected so that their values all reach the data under the same time conditions, so that multi-sample comparison can be carried out throughout the day. In addition, multiple biological samples are generally repeated and multiple measurement batches are repeated to reduce random errors and systematic errors. According to the measurement time of each sample recorded each time, the measurement time of the next biological repeat or batch repeat sample of the plant line is arranged to achieve uniform distribution of the measurement times of different biological repeats and sample repeats of each plant line in different time periods throughout the day, effectively reducing the probability of errors in the measurement and effectively ensuring the measurement effect and quality.

With the assistance of the other two second rolling wheels 7474, the auxiliary box 74 moves along the first track 6, and the auxiliary box 74 is moved to the position where the first track 6 communicates with the corresponding third track 62. Then start the fourth electric push rod 741, thereby driving the outer box body 743 to move downward, and separating the first rolling wheels 744 from the bottom end of the inner wall of the first track 6. Then start the fifth electric push rod 7475, thereby driving the inner box body 747 to move upward, and separating the second rolling wheels 7474 from the bottom end of the inner wall of the first track 6. Then start the second motor 742, thereby driving the first worm gear 746 to rotate, and causing the corresponding first worm 745 to rotate, thereby causing the corresponding two first rolling wheels 744 to rotate. With the assistance of the other two first rolling wheels 744, components such as the auxiliary box 74 enter the corresponding third track 62, and then move along the third track 62 to the position where the third track 62 communicates with the corresponding auxiliary track 63. Then, through the fourth electric push rod 741 and the fifth electric push rod 7475, the movement direction is changed, and components such as the auxiliary box 74 enter the corresponding auxiliary track 63. At this time, the support plate 7 is located inside the corresponding cultivation rack 8. Then, the third electric push rod 72 is activated to drive the tray 7 to move upward and contact the inner top of the cultivation rack 8. At this time, multiple positioning rods 82 are respectively inserted into multiple positioning holes 71, so that the tray 7 is positioned and installed with the cultivation rack 8. Then, the tray 7 continues to move upward to lift the cultivation rack 8. Then, by using the fourth electric push rod 741, the fifth electric push rod 7475, the second motor 742, the third motor 7471, the first worm gear 746, the first worm 745, the first rolling wheel 744, the second worm gear 7472, the second worm 7473 and the first rolling wheel 744, components such as the auxiliary box 74 move along the channels formed by the auxiliary track 63, the third track 62, the first track 6 and the second track 61, so as to transport the cultivation rack 8 into the detection room 2, realizing the directional movement of the cultivation rack 8, effectively reducing the probability of the cultivation rack 8 being misaligned, effectively reducing the probability of the planting pots being damaged, and effectively ensuring the measurement effect and quality; When the cultivation rack 8 moves to a suitable position in the detection room 2, then the host 3 activates the automatic door 46 on the measurement box 4 at the suitable position, so that the automatic door 46 opens. Then, through the first electric push rod 41 and the moving wheels 44, the placement plate 42 moves outward from the corresponding measurement box 4. Then, by using the first motor 51, the lead screw 52, the nut seat 58 and the second electric push rod 56, the mounting frame 54 moves to a suitable position, and then through the automatic fixture 55, the planting pots placed on the cultivation rack 8 are clamped; Then, by using the first motor 51, the lead screw 52, the nut seat 58, the second electric push rod 56, the mounting frame 54 and the automatic fixture 55, the clamped planting pots are placed on the upper end of the placement plate 42. Then, by using the first electric push rod 41, the four lifting rods 43 and the four moving wheels 44, the placement plate 42 and the planting pots are placed into the measurement box 4, and then the automatic door 46 is closed, so that the measurement box 4 containing the planting pots is in a sealed state; Again, following the above steps, different planting pots on the cultivation rack 8 are respectively placed into different measurement boxes 4. At the same time, the host 3 will detect whether each measurement box 4 has a planting pot inside. When there is a planting pot in the measurement box 4, it enters the waiting measurement sequence in the corresponding measurement box 4. The host 3 will sequentially detect each measurement box 4 in the waiting measurement sequence. When performing the detection, after the automatic door 46 is closed, immediately the host 3 and the corresponding suction pipe perform the operation of extracting gas from the measurement box 4, and the extracted gas is transported into the host 3 to detect the gas concentration.
