Technical Field

[0002] Banpo greenhouses are a type of facility agriculture building that has developed rapidly in northern my country, particularly in North China, Northeast China, and the Huanghuai region. They have significantly alleviated the problem of off-season vegetable supply in this region, particularly in northern my country. Tomatoes are the primary vegetable crop cultivated in these greenhouses and are one of the largest and most productive fruit and vegetable crops in my country. With the accelerating urbanization and aging of the Chinese population, the tomato industry is facing an increasingly severe labor shortage, and rising labor costs are severely impacting the industry's sustainable development. The presence of a rear wall in a Banpo greenhouse necessitates a certain distance between the two to minimize the impact of the front Banpo greenhouse on the daylighting of the rear. Furthermore, since greenhouse temperature is primarily influenced by sunlight, the need for active temperature adjustment requires a high reliance on heating and cooling systems, increasing energy consumption.

[0003] In the process of realizing the technical solutions of the invention in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems: the spacing between the semi-slope solar greenhouses is large, and the higher the dimension, the larger the spacing, resulting in a large area occupied. How to improve land utilization and increase economic output value; how to carry out automated mechanized cultivation work, reduce the number of laborers and labor intensity in production, improve production efficiency, and ensure the yield and quality of tomatoes. Summary of the Invention

[0004] The Summary of the Invention introduces a series of simplified concepts that will be further described in the Detailed Description of the Invention. The Summary of the Invention is not intended to limit the key features and essential features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] In order to solve the problem that the temperature in the greenhouse is greatly affected by sunlight and there is a high dependence on the heating and cooling systems, in the first aspect, the present invention proposes a method for automated cultivation of tomatoes in a facility, wherein the facility includes a greenhouse main body, and a translucent plastic covering film and a thermal insulation quilt adapted to the greenhouse main body to form a yin-yang greenhouse. The longitudinal direction of the yin-yang greenhouse is east-west, and a plurality of columns are provided between the sun-facing shed and the shady shed. The sun-facing shed and the shady shed are connected by the columns, and the columns are used to support the yin-yang greenhouse. A rollable ventilation and thermal insulation film is provided between the columns, including:

[0006] Monitor the temperature inside the sun-facing shed and the shade-facing shed separately;

[0007] Compare the current temperature of the sunny shed that is higher than the cultivation temperature of the plants in the sunny shed, and the current temperature of the shady shed that is lower than the cultivation temperature of the plants in the shady shed;

[0023] By using the gradient descent method, H is gradually adjusted according to the temperature error feedback to minimize the objective function F(H) and the total temperature error:

[0024] Minimize F(H)=E y +E i

[0025] Among them, T y is the current temperature of the sun shed, is the target temperature of the sun shed, T i is the current temperature of the shaded shed, is the target temperature of the shaded shed, A y is the area of ​​the sun shed, A i is the area of ​​the shaded shed, H is the height of the insulation film when rolled up (m) max is the maximum roll-up height of the insulation film, k is the heat transfer coefficient of the insulation film, C y is the heat capacity of the sun shed, C i is the heat capacity of the shaded shed, Δt is the time step, A=min(A y ,A i ) is the minimum effective area of ​​the two sheds, which is used to calculate heat exchange.

[0028] Optionally, also include:

[0029] At the rolling position of the thermal insulation film, air volume is generated to increase the rolling height of the thermal insulation film and adjust the adjustment speed of the temperature inside the sun-facing shed and the shade-facing shed.

[0030] Optionally, the step of creating air volume at the rolling-up position of the thermal insulation film to increase the rolling-up height of the thermal insulation film and adjust the adjustment speed of the temperature inside the sun-facing shed and the shade-facing shed includes:

[0031]

[0032] Where H is the height of the insulation film, V is the wind speed at the vent, E(t) is the energy consumption, and α, β, and γ are weight coefficients used to balance temperature control and energy consumption.

[0033] Randomly initialize a set of parameter combinations, calculate the objective function value corresponding to each parameter combination, select the parameter combination with better performance as the basis for the next generation according to the evaluation results, generate a new generation of parameter combinations through crossover and mutation operations, repeat the above steps, improve the parameter combination generation by generation, approach the optimal solution, reach the preset objective function value threshold, or reach the maximum number of iterations.

[0034] Optionally, also include:

[0035] The parameter combination of each particle is adjusted according to the global optimal and local optimal positions instead of generating a new generation of parameter combinations through crossover and mutation operations.

[0036] In a second aspect, the present invention further provides a facility tomato automated cultivation system, the facility comprising a greenhouse main body, and a translucent plastic covering film and a thermal insulation quilt adapted to the greenhouse main body to form a yin-yang greenhouse, the yin-yang greenhouse having an east-west length direction, a plurality of columns disposed between the sun-facing shed and the shady shed, the sun-facing shed and the shady shed being connected by the columns, the columns being used to support the yin-yang greenhouse, and a rollable ventilation and thermal insulation film disposed between the columns, the system comprising:

[0037] Monitoring unit, used to monitor the temperature inside the sun-facing shed and the shade-facing shed respectively;

[0038] An analysis unit is used to compare whether the current temperature of the sunny shed is higher than the cultivation temperature of the plants in the sunny shed, and whether the current temperature of the shady shed is lower than the cultivation temperature of the plants in the shady shed;

[0039] The regulating unit is used to adjust the temperature inside the sunny shed and the shady shed by adjusting the rolling height of the insulation film when the current temperature of the sunny shed is higher than the cultivation temperature of the plants in the sunny shed and the current temperature of the shady shed is lower than the cultivation temperature of the plants in the shady shed.

[0040] In a third aspect, an electronic device comprises: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor is configured to implement the steps of the automated cultivation method for facility tomatoes according to any one of the first aspects described above when executing the computer program stored in the memory.

[0041] In a fourth aspect, the present invention further proposes a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the method for automated cultivation of greenhouse tomatoes according to any one of the above items in the first aspect is implemented.

[0042] In summary, the automated greenhouse tomato cultivation method proposed in this application monitors the temperatures inside the sun-facing and shade-facing greenhouses separately; compares the current temperature of the sun-facing greenhouse when it is higher than the cultivation temperature of the plants inside the sun-facing greenhouse and the current temperature of the shade-facing greenhouse when it is lower than the cultivation temperature of the plants inside the shade-facing greenhouse; and when the current temperature of the sun-facing greenhouse is higher than the cultivation temperature of the plants inside the sun-facing greenhouse and lower than the cultivation temperature of the plants inside the shade-facing greenhouse, adjusts the temperature of the sun-facing and shade-facing greenhouses by adjusting the roll-up height of the insulation film. Thus, by separately monitoring the temperatures inside the sun-facing and shade-facing greenhouses and comparing the differences between the temperatures and the cultivation temperature of the plants, it is possible to accurately identify situations where the sun-facing greenhouse temperature is too high or the shade-facing greenhouse temperature is too low. This precise monitoring and comparison mechanism enables timely and effective temperature regulation in the greenhouse, ensuring an optimal growing environment for the crops. When the temperature of the sun-facing greenhouse is too high and the temperature of the shade-facing greenhouse is too low, the roll-up height of the insulation film is adjusted to promote air flow and heat exchange between the two greenhouses, allowing excess heat from the sun-facing greenhouse to be transferred to the shade-facing greenhouse. This method balances temperature distribution within the greenhouse, preventing overheating in the sun-facing shed and overcooling in the shade-facing shed, and improving heat utilization efficiency throughout the greenhouse. By utilizing natural heat exchange rather than relying on additional heating or cooling equipment, the greenhouse can maintain a suitable temperature while reducing energy consumption. This approach not only reduces greenhouse operating costs but also meets energy conservation and environmental protection requirements. Temperature is a key factor affecting vegetable growth. Precise temperature control ensures that both the sun-facing and shade-facing sheds remain within the optimal cultivation temperature range, promoting healthy crop growth and improving both quality and yield.

[0043] Enhance the adaptability of the greenhouse system: This method enables the greenhouse to dynamically respond to changes in the external environment (such as sunlight intensity and external temperature changes) by adjusting the roll-up height of the insulation film in real time, thereby improving the adaptability and flexibility of the system and ensuring a stable cultivation environment under various weather conditions.

[0044] The automated cultivation method for facility tomatoes of the present invention, and other advantages, objectives and features of the present invention will be partially reflected in the following description, and will also be understood by those skilled in the art through research and practice of the present invention.

Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments.

[0056] To solve the problem that the temperature in the greenhouse is greatly affected by sunlight and has a high dependence on the heating and cooling systems, please refer to Figure 1 , which is a flow chart of a method for automated cultivation of tomatoes in a facility provided in an embodiment of the present application. The facility includes a greenhouse main body, and a translucent plastic covering film and a thermal insulation quilt adapted to the greenhouse main body to construct a yin-yang greenhouse. The length direction of the yin-yang greenhouse is east-west. A plurality of columns are provided between the sun-facing shed and the shady-facing shed. The sun-facing shed and the shady-facing shed are connected by the columns. The columns are used to support the yin-yang greenhouse. A rollable ventilation and thermal insulation film is provided between the columns. The method may specifically include: steps S110 to S130.

[0057] S110, monitoring the temperature inside the sun-facing shed and the shade-facing shed respectively.

[0058] S120 , respectively comparing the current temperature of the sunny shed to be higher than the cultivation temperature of the plants in the sunny shed and the current temperature of the shady shed to be lower than the cultivation temperature of the plants in the shady shed.

[0059] S130, when the current temperature of the sunny shed is higher than the cultivation temperature of the plants in the sunny shed and the current temperature of the shady shed is lower than the cultivation temperature of the plants in the shady shed, adjust the temperature inside the sunny shed and the shady shed by adjusting the rolling height of the insulation film.

[0060] In some embodiments, a greenhouse is constructed by a yin-yang greenhouse including a greenhouse main body, a translucent plastic covering film adapted to the greenhouse main body, and a thermal insulation quilt. The longitudinal direction of the yin-yang greenhouse is east-west, and a plurality of columns 3 are provided between the sun-side shed 1 and the shady shed 2. The sun-side shed 1 and the shady shed 2 are connected by the columns 3. The columns 3 are used to support the yin-yang greenhouse. A rollable ventilation and thermal insulation film is provided on the columns for ventilation or thermal insulation between the sun-side shed and the shady shed.

[0061] Exemplarily, the greenhouse body includes a sun-side shed body and a shade-side shed body. The total span of the sun-side shed is 17m, of which the span of the sun-side shed is 10m and the span of the shade-side shed is 6.5m. The top height of the sun-side shed is 5.15m and the top height of the shade-side shed is 4.15m. The height of the columns is 4.15m, and the shade-side shed top is the same height as the columns. The main body of the sun-facing shed includes a first arch rod, a first pull rod and a first gable. The first gables on both sides are respectively located on both sides of the length of the main body of the sun-facing shed. One end of the first arch rod is installed and connected to the top of the column, and the other end is installed and connected to the foundation of the sun-facing side of the greenhouse. Multiple first arch rods are evenly spaced to form an arch frame of the main body of the sun-facing shed. The bottom angle 4 of the sun-facing shed formed by the first arch rod and the ground can be 70 to 80 degrees. In this embodiment, it is close to 75 degrees. Multiple first pull rods are transversely fixed to each first arch rod, and the multiple first pull rods are evenly distributed in parallel. The two ends of the first pull rod are respectively arranged on the first gables on both sides, and the height slope of the first gable follows the curvature of the first arch rod. Changes: The main body of the shade shed includes a second arch rod, a second tie rod and a second gable. The second gables on both sides are respectively located on both sides of the length of the main body of the shade shed. One end of the second arch rod is installed and connected to the top of the column, and the other end is installed and connected to the foundation of the shade side of the greenhouse. Multiple second arch rods are evenly spaced to form the arch frame of the main body of the shade shed. The bottom angle of the shade shed formed by the second arch rod and the ground can be 70 to 80 degrees. In this embodiment, it is close to 75 degrees. Multiple second tie rods are transversely fixed to each first arch rod. Multiple second tie rods are evenly distributed in parallel. The two ends of the second tie rod are respectively set on the second gables on both sides. The height slope of the second gable follows the curvature change of the second arch rod. The first tie rod, the second tie rod, the first arch rod and the second arch rod are metal composite materials with strong pressure resistance and elasticity, light weight, corrosion resistance and smooth surface.

[0062] Exemplarily, the length of the yin-yang greenhouse is 60m, the thickness of the gable is 0.5m, and the gable is provided with a door. Preferably, the door is a swing door 5, 2m wide and 2.4m high, for agricultural machinery to enter and exit.

[0063] Exemplarily, the light-transmitting plastic covering film is a drip-free, fog-eliminating polyolefin film with a thickness of 0.15 mm and a width of 130 mm; the thermal insulation quilt 6 adopts a polyethylene woven outer shell with thermal insulation material sandwiched inside the outer shell for insulating the greenhouse when the temperature is low.

[0064] Exemplarily, the roof of the sun-side shed near the shady-side shed is convex and has a rear slope, and the roof of the sun-side shed is connected to the pillars through the rear slope to form an inclined surface. The setting of the inclined surface improves the wind resistance and pressure resistance of the light-transmitting and heat-insulating material of the sun-side shed above the pillars, and enhances the stability of the sun-side shed; the roof of the sun-side shed near the sun-side shed is perpendicular to and connected to the pillars, which is conducive to the rolling up and laying down of the thermal insulation quilt, and is conducive to the discharge of rain and snow water from the roof.

[0065] Exemplarily, the shaded shed and the sun-facing shed are connected by a plurality of columns, the columns are evenly spaced, and the plurality of columns are arranged in rows, with the direction of the rows being east-west; the columns are provided with ventilation and heat-insulating films, which can be rolled up or covered on the columns. When the shaded shed and the sun-facing shed need to be ventilated with the outside world, the ventilation and heat-insulating films are rolled up; when the shaded shed or the sun-facing shed needs to be ventilated separately, the ventilation and heat-insulating films cover the columns, and the film rolling machine at the bottom and / or top of the shaded shed or the sun-facing shed is turned on. At the same time, the ventilation and heat-insulating films also play a role in heat preservation for the shaded shed and the sun-facing shed. In another embodiment, according to the light requirements of the vegetables in the shaded shed, the light-transmitting material of the ventilation and heat-insulating film is selected to meet the light requirements of the shade-loving vegetables; the rolling up and laying down of the ventilation and heat-insulating film can be achieved manually or by installing an automatic film rolling machine.

[0066] For example, in order to achieve ventilation between the yin and yang greenhouses and the outside world, automatic film rolling machines are respectively provided at the bottom and top of the shady shed and the sun shed.

[0067] According to some embodiments, further comprising:

[0068] Initialize the insulation film rolling height H value, starting from a smaller rolling height;

[0069] Calculate the current temperature changes of the sun-facing shed and the shade-facing shed;

[0070] Evaluate temperature error E y and E i , if the temperature error decreases, continue to increase H until the optimal solution is found. If the temperature error increases, reduce H and try to find the optimal balance point until the minimum temperature error or the set tolerance range is reached.

[0071] In some examples, this also includes:

[0072] The rolling height of the insulation film is calculated by the following formula:

[0073] In the time step Δt, the heat Q transferred from the sun-facing shed to the shade-facing shed can be expressed as:

[0074]

[0075] The temperature change of the sun shed can be expressed as:

[0076]

[0077] The temperature change of the shade shed can be expressed as:

[0078]

[0079] Temperature error calculation:

[0080]

[0081] By using the gradient descent method, H is gradually adjusted according to the temperature error feedback to minimize the objective function F(H) and the total temperature error:

[0082] Minimize F(H)=E y +E i

[0083] Among them, T y is the current temperature of the sun shed, is the target temperature of the sun shed, T i is the current temperature of the shaded shed, is the target temperature of the shaded shed, A y is the area of ​​the sun shed, A i is the area of ​​the shaded shed, H is the height of the insulation film when rolled up (m) max is the maximum roll-up height of the insulation film, k is the heat transfer coefficient of the insulation film, C y is the heat capacity of the sun shed, C i is the heat capacity of the shaded shed, Δt is the time step, A=min(A y ,A i ) is the minimum effective area of ​​the two sheds, which is used to calculate heat exchange.

[0084] In some examples, the method further includes:

[0085] Optimize the objective function F(H)=E using the Bayesian optimization algorithm y +E i .

[0086] For example, Bayesian optimization can learn from historical data and intelligently select the insulation film height H for the next trial in each iteration, thereby finding the optimal solution more quickly and accurately than the gradient descent method.

[0087] Understandably, temperature regulation only considers the height of the insulation film, without comprehensively factoring in the impact of multiple variables on the greenhouse environment, such as humidity, wind speed, external weather changes, and crop growth stage. This can lead to insufficient regulation accuracy. Furthermore, the original method used a linear formula to approximate the heat exchange process, ignoring the nonlinear characteristics of temperature regulation, such as the complexity of air convection and the uneven temperature distribution across different areas of the greenhouse. This approximation can lead to unsatisfactory predicted temperature regulation results.

[0088] To solve the above problems, some examples also include:

[0089] At the rolling position of the thermal insulation film, air volume is generated to increase the rolling height of the thermal insulation film and adjust the adjustment speed of the temperature inside the sun-facing shed and the shade-facing shed.

[0090] In some examples, the step of generating air volume at the rolling-up position of the thermal insulation film to increase the rolling-up height of the thermal insulation film and adjust the adjustment speed of the temperature inside the sun-facing shed and the shade-facing shed includes:

[0091]

[0092] Where H is the height of the insulation film, V is the wind speed at the vent, E(t) is the energy consumption, and α, β, and γ are weight coefficients used to balance temperature control and energy consumption.

[0093] Randomly initialize a set of parameter combinations, calculate the objective function value corresponding to each parameter combination, select the parameter combination with better performance as the basis for the next generation according to the evaluation results, generate a new generation of parameter combinations through crossover and mutation operations, repeat the above steps, improve the parameter combination generation by generation, approach the optimal solution, reach the preset objective function value threshold, or reach the maximum number of iterations.

[0094] In some examples, this also includes:

[0095] The parameter combination of each particle is adjusted according to the global optimal and local optimal positions instead of generating a new generation of parameter combinations through crossover and mutation operations.

[0096] For example, nonlinear optimization algorithms (such as genetic algorithms, particle swarm optimization, etc.) are used to more accurately model and control the complex heat exchange process in the greenhouse, and the control strategy is dynamically adjusted in combination with a real-time feedback system. Genetic algorithms simulate the natural selection process and solve optimization problems through operations such as genetic variation, crossover, and selection. It is applicable to high-dimensional, nonlinear, and multi-peak optimization problems. It is suitable for optimizing the height of the insulation film, ventilation parameters, and thermal management strategies of the greenhouse to minimize temperature deviation, energy consumption, and meet the growth needs of crops. Particle swarm optimization simulates the group behavior of flocks of birds or fish, and gradually approaches the global optimal solution through information sharing between individual particles. It is suitable for nonlinear optimization problems in continuous space. In greenhouse control, PSO can be used to optimize temperature regulation parameters (such as insulation film height, wind speed control) to adapt to dynamic environmental changes. By adopting a combined strategy of nonlinear optimization and real-time feedback control, the regulation of the greenhouse environment will be more refined and intelligent, effectively improving the efficiency and benefits of agricultural production.

[0136] (2) Compound fertilizer for base fertilizer

[0137] The compound fertilizer includes phosphate fertilizer, potash fertilizer and medium and trace element fertilizer. In low-fertility soil, the amount of compound fertilizer applied per mu is 30 to 50 kg. In this embodiment, the preferred amount of compound fertilizer applied is 40 kg.

[0138] A crawler-type base fertilizer spreader is used. The model used in this embodiment is MSX650, with a spreading width of 1.5m and a spreading amount of 0.8m 3 / min, when tilling the land, the base fertilizer is mixed with the soil. A soil moisture content of 25% can keep the soil moist to promote the decomposition of the base fertilizer and the absorption of nutrients by tomato seedlings.

[0139] S3: In the greenhouse, the soil is ridged for tomato seedlings by an integrated ridge-forming and film-covering machine, and the ridges are trimmed into cultivation beds. The distance between adjacent cultivation beds 7 is 1.6m, the cultivation beds are east-west and parallel, the ridge 8 is 1m wide, the upper bottom width of the cultivation bed is 55cm, and the lower bottom width is 60cm. Two drip irrigation pipes 9 are laid on the surface of the cultivation bed, and the distance between the two drip irrigation pipes is 20cm. The drip irrigation pipe 9 is 15cm away from the outer edge of the upper bottom of the cultivation bed. The bed surface height of the cultivation bed 7 is 15cm. The cultivation bed is covered with a ground film, and the drip irrigation pipe is laid under the ground film; in the sunny shed, the edge of the cultivation bed close to the bottom of the sunny shed is at a horizontal distance of 90cm from the bottom of the sunny shed. In the shady shed, the edge of the cultivation bed close to the bottom of the shady shed is at a horizontal distance of 70cm from the bottom of the shady shed.

[0140] In a specific embodiment, the ridging and film covering machine used is model YTLM-60, and the laid ground film has a thickness of 0.01 mm and a width of 130 mm.

[0141] In a specific embodiment, the drip irrigation pipe is used to water the tomatoes and add fertilizers according to the growth of the tomatoes.

[0142] S4: Use a semi-automatic or fully automatic fruit and vegetable transplanter to transplant tomato seedlings to the cultivation bed, planting in double rows with a row spacing of 30 cm and a plant spacing of 40 cm. The tomato seedlings are planted along the outside of each drip irrigation pipe. Tomato seedlings of the same variety are transplanted in the shaded greenhouse and the sun-facing greenhouse in staggered batches. Early-maturing and late-maturing tomato seedlings are transplanted in the sun-facing greenhouse and the shade-facing greenhouse in the same batch.

[0143] In a specific embodiment, the mechanized transplanted tomato seedlings have thick stems, short internodes, a plant height of 12 to 17 cm, a stem thickness of at least 0.3 cm, complete cotyledons, stretched leaves, 4 to 5 true leaves, normal leaf color, dense and tender white roots, thick root hairs, and the roots tightly wrap around the substrate to form a complete root ball, without mechanical damage and without diseases and insect pests.

[0144] In a specific embodiment, the row spacing of tomato seedlings is 30 cm and the plant spacing is 33 cm. Watering, fertilizing and plant management are carried out in a timely manner according to the growth of the tomato seedlings to ensure the tomato harvest yield and fruit quality.

[0145] In a specific embodiment, the same variety of tomatoes is planted in mid-to-late February. The first crop of tomato seedlings is transplanted in a sunny greenhouse. Two weeks later, the second crop of tomato seedlings is transplanted in a shady greenhouse and can be harvested in mid-to-late May. The third crop of tomato seedlings is planted in a sunny greenhouse in mid-to-late September. Two weeks later, the fourth crop of tomato seedlings is planted in a shady greenhouse and can be harvested in mid-to-late December. For different varieties of tomato seedlings, the planting period is mid-to-late February in spring and mid-to-late September in autumn. Relatively early-maturing tomato seedlings are transplanted in a sunny greenhouse and enter the harvest period in mid-to-late May and mid-to-late December, respectively. Relatively late-maturing tomato seedlings are transplanted in a shady greenhouse. The tomato seedlings are planted in the same crop in both the sunny and shady greenhouses.

[0146] The yin-yang greenhouse fully realizes the efficient use of land, ensures the average per-acre yield of tomatoes and the continuous supply of tomatoes, and staggers the market launch, improving economic efficiency. By planting tomato seedlings at different stages in the shady and sunny greenhouses, the ventilation and light transmittance of the greenhouse are improved, reducing the occurrence of diseases and pests, and thus improving the stress resistance of tomatoes, which helps to improve the yield and quality of tomatoes.

[0148] (1) Planting and seedling slowing down period

[0149] In a specific embodiment, the temperature and soil moisture requirements for the transplanting and seedling acclimatization period are relatively high. After the plants are transplanted, water is poured thoroughly on the substrate and surrounding soil around which the roots of the plants are entangled, so that the roots are in close contact with the mud. The transplanting period begins after 7 days. During the seedling acclimatization period, water is properly controlled to promote the roots to grow deep. Water is applied in the morning every 3 days. The amount of water should not be too large, so that the soil is moist with a moisture content of 65%. 0.8 kg of microbial agent is added to the water for the first transplanting and seedling acclimatization per mu. The microbial agent enables the beneficial bacteria in the roots of tomatoes to actively exert their advantages in niche competition, thereby protecting the roots from infection by harmful bacteria, thereby promoting the healthy growth of tomato plants.

[0150] In a specific embodiment, the daytime temperature is controlled at 23-28 degrees, and the nighttime temperature is controlled at 15-18 degrees.

[0151] In a specific embodiment, when the outdoor temperature is suitable during the day, appropriate ventilation can be carried out according to the growth of the plants. For example, the ventilation and thermal insulation film between the shade and sun sheds is rolled up, and a film rolling machine rolls up the covering film of the sun shed and another film rolling machine rolls up the covering film of the shade shed to ventilate the entire shade and sun greenhouse. Alternatively, the ventilation and thermal insulation film on the pillars between the shade shed and the sun shed is covered on the pillars, that is, in an unrolled state, and the shade and sun sheds are ventilated separately. The size of the vents can be adjusted appropriately in the above situations.

[0152] (2) Seedling growth period

[0153] In a specific embodiment, the tomato seedlings enter the seedling growth period 10 days after being planted and the seedlings begin to bud. When the soil is dry, water it appropriately to make the soil moisture content 48%; the daytime temperature is controlled at 20 to 28 degrees, and the nighttime temperature is 13 to 18 degrees. Appropriate ventilation can be carried out according to weather conditions and the yin and yang conditions of the greenhouse.

[0154] (3) Flowering and fruiting period

[0155] In a specific embodiment, the amount of watering is moderate, so that the soil is moist, with a moisture content of 35%, and watering is done twice a week. The watering frequency can be adjusted according to the weather, soil moisture, and plant growth. A water-soluble compound fertilizer containing phosphorus and potassium is applied from the beginning of bud formation to before flowering to promote flower bud differentiation and fruit development. Fertilizer is applied every 12 days, with each application of 15 kilograms per mu. The daytime temperature is controlled at 20-27 degrees Celsius, and the nighttime temperature is controlled at 14-17 degrees Celsius. The size of the ventilation holes is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

[0156] (4) Fruiting period

[0157] In a specific embodiment, the amount of watering is moderate to make the soil moist with a water content of 40%, and watering is performed once a week. The watering frequency can be adjusted according to the weather, soil moisture and plant growth. Phosphorus and potassium fertilizers are applied once every 10 days, with 4.8 kg of diammonium phosphate fertilizer and 3.5 kg of potassium sulfate fertilizer applied per mu. The amount of phosphorus and potassium fertilizers applied is appropriately adjusted according to the soil and plant results. The daytime temperature is controlled at 24 to 27 degrees, and the nighttime temperature is controlled at 12 to 16 degrees. The size of the vents is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

The transplanting period begins after 6 days. During the seedling acclimatization period, water is properly controlled to promote the roots to grow deep. Water is applied in the morning every 3 days. The amount of water should not be too large, so that the soil is moist with a moisture content of 68%. 0.8 kg of microbial agent is added to the water for the first transplanting and seedling acclimatization per mu. The microbial agent enables the beneficial bacteria in the roots of tomatoes to actively exert their advantages in niche competition, thereby protecting the roots from infection by harmful bacteria, thereby promoting the healthy growth of tomato plants.

[0186] In a specific embodiment, the daytime temperature is controlled at 23-28 degrees, and the nighttime temperature is controlled at 15-18 degrees.

[0187] In a specific embodiment, when the outdoor temperature is suitable during the day, appropriate ventilation can be carried out according to the growth of the plants. For example, the ventilation and thermal insulation film between the shade and sun sheds is rolled up, and a film rolling machine rolls up the covering film of the sun shed and another film rolling machine rolls up the covering film of the shade shed to ventilate the entire shade and sun greenhouse. Alternatively, the ventilation and thermal insulation film on the pillars between the shade shed and the sun shed is covered on the pillars, that is, in an unrolled state, and the shade and sun sheds are ventilated separately. The size of the vents can be adjusted appropriately in the above situations.

[0188] (2) Seedling growth period

[0189] In a specific embodiment, tomato seedlings enter the seedling growth period 8 days after planting and acclimatization, until buds begin to appear, and water the soil appropriately after the soil becomes dry, so that the soil moisture content is 52%; the daytime temperature is controlled at 20 to 28 degrees, and the nighttime temperature is 13 to 18 degrees. Appropriate ventilation can be carried out according to weather conditions and the yin and yang conditions of the greenhouse.

[0190] (3) Flowering and fruiting period

[0191] In a specific embodiment, the amount of watering is moderate, so that the soil is moist, with a moisture content of 40%, and watering is done twice a week. The watering frequency can be adjusted according to the weather, soil moisture, and plant growth. A water-soluble compound fertilizer containing phosphorus and potassium is applied from the beginning of bud formation to before flowering to promote flower bud differentiation and fruit development. Fertilizer is applied every 10 days, with each application of 14.5 kg per mu. The daytime temperature is controlled at 20-27 degrees Celsius, and the nighttime temperature is controlled at 14-17 degrees Celsius. The size of the ventilation holes is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

[0192] (4) Fruiting period

[0193] In a specific embodiment, the amount of watering is moderate to make the soil moist with a water content of 35%, and watering is performed once a week. The watering frequency can be adjusted according to the weather, soil moisture and plant growth. Phosphorus and potassium fertilizers are applied once every 10 days, with 5.2 kg of diammonium phosphate fertilizer and 4.8 kg of potassium sulfate fertilizer applied per mu. The amount of phosphorus and potassium fertilizers applied is appropriately adjusted according to the soil and plant results. The daytime temperature is controlled at 24 to 27 degrees, and the nighttime temperature is controlled at 13 to 17 degrees. The size of the vents is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

[0194] S6: Configure a mobile platform for high-seedling operations to assist manual management of tomato seedlings, including pruning, splitting, hanging vines, and picking fruits.

[0195] Example 3

[0196] The parameters and planting methods of Example 3 are basically the same as those of Example 1, except that in Example 3, tomatoes are planted in a yin-yang greenhouse with high fertility soil. When applying base fertilizer, the amount of organic fertilizer applied per mu of high fertility soil is 0.5 to 1.0 tons, and the amount of compound fertilizer applied per mu is 0 to 15 kilograms. Preferably, the amount of organic fertilizer applied in this embodiment is 0.6 tons, and the amount of compound fertilizer applied is 5 kilograms.

[0197] The judgment criteria for soil fertility in Examples 1, 2 and 3 of the present application are based on the Beijing soil nutrient classification standards.

[0198] The three embodiments provided in this application differ in that the data in the embodiments are adjusted, the production efficiency of the three embodiments is the same, and the tomato yield and quality are also almost the same.

[0199] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0200] (1) A fertilizer spreader was used to apply fertilizer, a rotary tiller was used to till or deep-plow the soil, an integrated ridging and film covering machine was used to ridge, lay drip irrigation pipes and lay ground film, and an automatic fruit and vegetable transplanter was used to transplant tomato seedlings. A high-vine plant was managed through a high-seedling operation mobile platform. This effectively solved the technical problem of relying on manual labor and low production efficiency in the existing technology for tomato planting and management, thereby achieving the technical effect of full mechanization of tomato operation management, reducing labor costs, and greatly improving labor and production efficiency.

[0201] (2) The height and width of the greenhouse, gable height and gable door size, ridge spacing, ridge-ditch spacing and bed width, plant spacing, row spacing, and watering, fertilization, ventilation and temperature that affect tomato yield and quality were designed to coordinate with the mechanical facilities. This effectively solved the problem of low mechanization level in the existing technology, thereby realizing the integration of agricultural machinery and agronomy, improving the degree of mechanical automation and production efficiency, and ensuring the technical effect of tomato yield and quality.

[0202] (3) The yin-yang greenhouse structure is adopted to make full use of the shadow area caused by the half-slope shed sunroom. A shade shed is attached to the north side of the original wall, and the wall is removed at the same time. Multiple columns are set between the shade shed and the sun shed. The columns are provided with ventilation and heat preservation film, which effectively solves the technical problem of low land utilization rate of the existing half-slope shed sunroom greenhouse, and then realizes staggered planting, staggered market launch or planting shade-loving vegetables in the shade shed, etc., which greatly improves land utilization efficiency and increases the economic value of greenhouse output. In addition, the overall cost of the greenhouse is low, and the shade shed can reduce the heat loss of the north wall of the sun shed, saving energy.

[0203] (4) The shady shed and the sun-facing shed are connected by a plurality of columns, which are evenly spaced and arranged in rows in an east-west direction; a ventilation and thermal insulation film is provided on the columns, which can be rolled up or covered. When the shady shed and the sun-facing shed need to be ventilated to the outside, the ventilation and thermal insulation film is rolled up; when the shady shed or the sun-facing shed needs to be ventilated separately, the ventilation and thermal insulation film covers the columns. At the same time, the ventilation and thermal insulation film also plays a role in heat preservation for the shady shed and the sun-facing shed.

[0204] (5) The roof of the sun-side shed near the shady shed is convex and has a rear slope. The roof of the sun-side shed is connected to the pillars through the rear slope to form an inclined surface. The setting of the inclined surface improves the wind resistance and pressure resistance of the light-transmitting and heat-insulating material of the sun-side shed above the pillars, and enhances the stability of the sun-side shed; the roof of the shady shed near the sun-side shed is perpendicular to and connected to the pillars, which is conducive to the rolling up and laying down of the heat-insulating quilt, and is conducive to the discharge of rain and snow water from the roof.

[0205] To improve greenhouse mechanization efficiency, a simple mobile platform for arranging tall crops can also be installed. Any mobile platform capable of manual or intelligent control of movement and parking, allowing personnel to perform operations such as arranging tall crops, can be used in this solution. The specific structure of the mobile platform is not limited here.

[0206] In some examples, with the help of a mobile platform for arranging tall seedling crops, the above-mentioned automated greenhouse tomato cultivation method may further include:

[0207] The action status data of the staff on the mobile platform is obtained. When the matching degree between the action status data and the standard state of pruning, forking or hanging vines is greater than a preset matching degree, the state of the mobile platform is maintained in a parked state.

[0208] It is understandable that the core principle of this solution is based on the combination of motion recognition technology and automated control technology. Its basic process includes: Motion recognition: obtaining the motion data of the staff on the mobile platform through sensors (such as cameras, accelerometers or force sensors), such as the movement trajectory of the arm, angle changes, force changes, etc. Motion matching calculation: comparing the motion data collected in real time with the preset standard operations (pruning, crossing, hanging vines, etc.). This standard state can be manually set by an expert or defined based on a model trained with historical data. Control the platform's parked state: When the system detects that the matching degree between the staff's motion and the standard operation exceeds a certain threshold, it is considered that the staff is performing an effective operation. At this time, the mobile platform is kept in a parked state so that the staff can complete the work smoothly. Once the matching degree decreases (such as the operation is completed), the platform resumes the mobile state.

[0209] Specifically, for the configuration of the motion recognition system:

[0210] Sensor placement: Multiple sensors can be installed on the mobile platform to capture the worker's motion status. Commonly used sensors include:

[0211] Image sensor: Monitors hand and body movements within the work area. For example, it monitors arm position when pruning or the detailed operation details when making a cross.

[0212] Accelerometer: Worn on the worker's arm or tool to monitor movement speed, frequency, and angle changes.

[0213] Force sensors: Mounted on work tools, they monitor the applied force to ensure compliance with standard forces for operations such as pruning or forking.

[0214] For the implementation of action matching:

[0215] Establishing Preset Standards: Through multiple trials and expert experience, we determine the "standard movements" for pruning, splitting, and vine hanging, including factors such as hand movement trajectory, applied force, movement angle, and operation duration. These standards can be stored in the system's database for real-time comparison.

[0216] Real-time comparison and feedback: The system collects the worker's motion data in real time and uses an algorithm to calculate its match with the standard motion. For example, when pruning a branch, the system compares the actual hand motion trajectory with the standard trajectory. If the match exceeds a preset threshold (e.g., 90%), the operation is considered valid.

[0217] For automatic control of mobile platforms:

[0218] Platform parking control: When the matching degree exceeds the preset value, the system instructs the platform to remain parked until the operation is completed. Once the action matching degree decreases (such as the operation is completed or the action stops), the system instructs the platform to resume movement.

[0219] Intelligent Scheduling: If multiple workers are working in the same greenhouse, each mobile platform can be independently controlled based on the individual operation. Once all workers have completed their operation, the platforms will resume their mobile state simultaneously.

[0220] Therefore, through the above principles and implementation methods, the mobile platform can automatically stop according to the real-time status of the operation, reducing the need for frequent manual operation of the platform. Workers no longer need to manually control the movement and stopping of the platform, and can focus on the arrangement of tall crops. This will significantly improve work efficiency. Through precise data collection from multiple sensors (such as cameras, accelerometers, etc.) and comparison with standard operations, the system can accurately identify the operation status, ensuring that the platform stops at the required time, avoiding misjudgments. In particular, the arrangement of tall crops requires workers to frequently operate pedals or buttons to control the mobile platform. This solution greatly reduces the frequency of manual intervention through automated identification and control, allowing workers to focus on core operations and reduce physical exertion. During the arrangement of tall crops, improper movements may cause damage to the plants. By judging the real-time matching of movements, the system can prompt workers and make timely corrections when the operation does not meet the standards. This function can reduce the probability of incorrect operation and improve the quality of crop arrangement.

[0221] For example, a worker stands on a mobile platform, preparing to prune tomatoes. The system detects through a camera that their hand movements closely match the standard pruning trajectory (e.g., a 95% match). The system then instructs the mobile platform to remain stationary until the pruning is complete. Once pruning is complete, the hand movements cease, the match decreases, and the platform restarts and moves to the next tomato plant. As the worker performs the cross-marking operation, the accelerometer detects that their arm movements meet the standard speed and force for marking a tomato plant, and the system keeps the platform stationary. If the worker's cross-marking movement is detected to be substandard (e.g., insufficient force), the system prompts the operator to adjust their movements to ensure quality. By introducing motion recognition and automated control, the mobile platform for pruning tall crops can significantly improve efficiency, reduce manual intervention and labor intensity, and enhance the accuracy of crop management in automated greenhouse tomato cultivation. This solution is applicable not only to tomato cultivation but can also be extended to other tall crop management scenarios, further enhancing agricultural mechanization and intelligence.

[0222] For example, if there are multiple mobile platforms in a greenhouse, the system can coordinate control based on the status of each platform to ensure that multiple platforms moving in the same area do not cause congestion. Furthermore, when all operations in a certain area are completed, the system can dispatch the platforms to the next area.

[0223] In some examples, such as Figures 1c to 1e The greenhouse is equipped with a simple mobile platform for arranging tall seedlings. The elevation diagram shows that 10 is the platform frame for workers to operate, 11 is the operating lever, 12 is the small pulley, 13 is the lifting frame, 14 is the front wheel, and 15 is the rear wheel. During the tomato planting process, manual pruning, forking, hanging vines and other plant management are required. The greenhouse is equipped with a simple mobile platform for arranging tall seedlings to assist workers in plant management. When workers perform pruning, forking, hanging vines and other operations, they pull the operating lever 11 to change the crop arranging platform mode to a fixed state (such as Figure 1e ), that is, the operating lever 11 pulls the small pulley 12, and the small pulley drives the lifting frame 13 to retract the front wheel 14 and the rear wheel 15 of the simple high seedling crop sorting platform, and the frame 10 of the crop platform falls to the ground, making the working platform more stable and convenient for the staff to manage the plants. When it is necessary to move forward, push the operating lever 11 to change the crop platform mode to the mobile state (such as Figure 1d ), pushing the operating lever 11 lowers the small pulley 12, which in turn pushes the lifting frame 13, lowering the front and rear wheels 14, 15 of the simple tall crop arrangement platform, propelling the platform forward. This effectively solves the high-intensity handling problems caused by long greenhouses and a lack of suitable logistics equipment, improving worker efficiency and reducing labor intensity.

The absolute moisture content of the soil is 15% to 25%. The base fertilizer includes organic fertilizer and compound fertilizer. The amount of organic fertilizer and compound fertilizer applied is adapted to the soil fertility.

[0226] In the yin-yang greenhouse, the soil is ridged by an integrated ridge-forming and film-covering machine, and the ridges are trimmed into cultivation beds, the distance between adjacent cultivation beds is 1.6-1.8 m, the cultivation beds are east-west and parallel, the upper bottom width of the cultivation beds is 55-65 cm, the lower bottom width is 60-70 cm, and the bed surface height is 10-15 cm, two drip irrigation pipes are laid on the surface of the cultivation beds, the drip irrigation pipes are 17.5-22.5 cm away from the outer edge of the upper bottom of the cultivation beds, the two drip irrigation pipes are 20 cm apart, and the cultivation beds are covered with ground film, and the drip irrigation pipes are laid below the ground film;

[0227] Use a semi-automatic or fully automatic fruit and vegetable transplanter to transplant tomato seedlings to the cultivation bed, planting in double rows with a row spacing of 30-45 cm and a plant spacing of 33-40 cm. Plant the tomato seedlings along the outside of each drip irrigation pipe. Tomato seedlings of the same variety are transplanted and planted in the sunny and shady greenhouses at different times. Early-maturing and late-maturing tomato seedlings of different varieties are transplanted and planted in the sunny and shady greenhouses at the same time.
