Description

Technical Field

[0001] This application relates to the technical field of orchard environment regulation, and specifically relates to an intelligent regulation system and method for the growth environment of apple tree growth status. Background Art

[0002] Reasonable pruning can make the crown structure of apple trees more reasonable, allowing more sunlight to penetrate into the interior and lower part of the crown, improving the photosynthesis efficiency. At the same time, reasonable regulation of pests and diseases helps to maintain the balance of the orchard ecosystem and the stability of the ecosystem. Therefore, this application proposes an intelligent regulation system and method for the growth environment of apple tree growth status.

[0003] The existing technology, such as the intelligent regulation system for the growth environment of apple trees disclosed in the invention patent application with the publication number of CN118537159A, includes calculating environmental factors and the growth status of apple trees using preprocessed data, converting the obtained environmental factors and the growth status of apple trees into data and inputting them; then judging whether the growth status of the apple trees reaches the threshold for the input data. If it has reached, analyze the environmental factors; if not, comprehensively analyze the environmental factors and the growth status of the apple trees, and then allocate the water quota within the apple tree planting area.

[0004] For the above solution, there are the following technical problems: 1. The current technology mainly calculates environmental factors and the growth status of apple trees, and then allocates the water quota within the apple tree planting area. The current technology only allocates water resources within the planting area, and does not consider that if the apple tree branches are too dense, it will affect the photosynthesis of the apple trees. At this time, only controlling the water quota of the apple trees cannot ensure the healthy growth of the apple trees.

[0005] 2. The current technology does not consider that after the water quota is allocated, reasonable water resources will not only promote the growth of apple trees, but also promote the reproduction of germs and pests within the apple tree planting area. Therefore, reasonable pest and disease control of apple trees is also crucial. The neglect of this aspect in the current technology will increase the probability of apple trees being infected with pests and diseases, and thus cannot guarantee the quality and quality of apple tree fruits. Summary of the Invention

[0006] The purpose of this application is to provide an intelligent regulation system and method for the growth environment of apple tree growth status, which solves the problems existing in the background art.

[0007] To solve the above technical problems, this application adopts the following technical solutions: In the first aspect, this application provides an intelligent regulation system for the growth environment of apple tree growth status, including: Intelligent regulation network module: used to build an intelligent regulation network in the orchard, so as to realize the intelligent regulation of the growth environment of each apple tree in the orchard.

[0008] Apple tree monitoring module: It is used to monitor the branch information, pest and disease information, and environmental information of each apple tree in the orchard, obtain the branches of each level of each apple tree, and transmit them to the central control unit.

[0009] Analysis and regulation module: It is used to analyze the branch information, pest and disease information, and environmental information of each apple tree in the orchard, and then regulate the growth environment of each apple tree in the orchard.

[0010] Regulation feedback module: It is used to count the apple yield in the orchard after fruit picking, and then evaluate the regulation effect of the growth environment of the apple trees in the orchard.

[0011] In the second aspect of this application, an intelligent regulation method for the growth environment of apple tree growth states is provided, including: Step 1, intelligent regulation network: It is used to build an intelligent regulation network in the orchard, so as to realize the intelligent regulation of the growth environment of each apple tree in the orchard.

[0012] Step 2, apple tree monitoring: It is used to monitor the branch information, pest and disease information, and environmental information of each apple tree in the orchard, obtain the branches of each level of each apple tree, and transmit them to the central control unit.

[0013] Step 3, analysis and regulation: It is used to analyze the branch information, pest and disease information, and environmental information of each apple tree in the orchard, and then regulate the growth environment of each apple tree in the orchard.

[0014] Step 4: Regulation feedback module: It is used to count the apple yield in the orchard after fruit picking, and then evaluate the regulation effect of the growth environment of the apple trees in the orchard.

[0015] The beneficial effects of this application are as follows: 1. This application connects the various sensors in the orchard to the central control unit through wireless sensing technology, realizing the automation and intelligence of orchard management, reducing the workload of manual monitoring and operation, and collecting the branch information, pest and disease information, and environmental information of each apple tree in the orchard through the various sensors installed in the orchard. Then, according to the branch information of each apple tree, the branch density of the apple tree is regulated, effectively reducing the branch density to ensure light and ventilation, enhancing photosynthesis, reducing the humidity of the orchard, inhibiting the growth of germs. After the branch regulation is completed, according to the pest and disease information and environmental information in the orchard, the orchard pests and diseases are regulated. From the perspectives of light and temperature, biological inhibitors and natural enemy insects are used to inhibit the pests and diseases, avoiding blind use of pesticides and improving the control effect.

[0016] 2. By installing various sensors at multiple locations in the orchard and on each apple tree, this application comprehensively and accurately collects various information on the growth environment of apple trees. Each sensor promptly transmits the collected information to the central control unit, which can quickly analyze the data and formulate control strategies, thereby controlling the control device to adjust the orchard environment in real time. The intelligent control network realizes the automation and intelligence of orchard management, reduces the workload of manual monitoring and operation. Fruit farmers do not need to frequently measure various environmental parameters and manually adjust them in the orchard, saving labor, material and time costs. At the same time, the central control unit can manage multiple control devices simultaneously and uniformly control the entire orchard, improving the management efficiency and making orchard management more convenient and efficient.

[0017] 3. This application collects the branch information, pest and disease information, and environmental information of each apple tree in the orchard through various sensors installed in the orchard, thereby providing a data basis for the subsequent regulation of the growth environment of each apple tree. The branch density of the apple tree is regulated according to the branch information of each apple tree, effectively reducing the branch density, thereby ensuring sufficient light and ventilation inside the tree crown, enabling more leaves to receive sufficient sunlight, enhancing photosynthesis. At the same time, good ventilation can reduce the humidity in the orchard, inhibit the growth of bacteria, and reduce the environmental conditions for the occurrence of pests and diseases. After the regulation is completed, the pests and diseases in the orchard are regulated according to the pest and disease information and environmental information in the orchard, so as to accurately predict the types and development trends of pests and diseases, and then suppress the pests and diseases from the perspectives of light and temperature, supplemented by biological inhibitors and natural enemy insects, reducing the control cost and avoiding environmental pollution caused by blind use of pesticides.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0022] Referring to Figure 1 As shown, the present application provides an intelligent control system for the growth environment of apple trees, including the following modules: Intelligent control network module: used to build an intelligent control network in the orchard, so as to realize the intelligent control of the growth environment of each apple tree in the orchard.

[0023] In a specific example, the process of building an intelligent control network in the orchard to realize the intelligent control of the growth environment of each apple tree in the orchard is as follows: Install light sensors on the crowns of each apple tree at a first preset distance, install soil information sensors in the soil at a second preset distance, and install light sensors and air information sensors at the branches and tree tops of each apple tree at a third preset distance; At the same time, install a first control device between the branches of each apple tree in the orchard at a fifth preset distance, and install a second control device at a sixth preset distance. Each sensor and each control device are connected to the central control unit through wireless sensor network technology. Each sensor transmits the collected information to the central control unit, and the central control unit analyzes the information collected by each sensor, and then formulates a control strategy to control each control device to adjust the growth environment of the apple trees in the orchard.

[0024] It should be noted that the first preset distance, the second preset distance, the third preset distance, the fourth preset distance, the fifth preset distance, and the sixth preset distance are all determined by the coverage range of specific sensors or control devices. For example, if the collection range of the soil information sensor is 2 meters, the first preset distance is set to 2 meters.

[0025] It should be noted that the first control device and the second control device are a supplementary light device and a temperature compensation device respectively.

[0026] Apple tree monitoring module: used to monitor the branch information, pest and disease information, and environmental information of each apple tree in the orchard, and obtain the branches of each apple tree at all levels, and transmit them to the central control unit.

[0027] In a specific example, the branch information, pest and disease information, and environmental information of each apple tree in the orchard are monitored, and each level of branches of each apple tree is obtained. The specific process is as follows: The branch information includes the lengths of the branches of each apple tree and the distances between the adjacent branches of each adjacent apple tree; the pest and disease information includes the contents of fungi, bacteria, viruses, and pests in the soil and air that can cause apple tree pests and diseases; the environmental information includes light and temperature.

[0028] Images and videos of each apple tree are collected by the camera devices installed in the orchard. The branches connected to the trunk of each apple tree are recorded as each first-level branch, the branches connected to each first-level branch are recorded as each second-level branch, and the branches other than each first-level branch connected to each second-level branch are recorded as each third-level branch. Accordingly, the branches of each apple tree are classified to obtain each level of branches of each apple tree.

[0029] Analysis and regulation module: It is used to analyze the branch information, pest and disease information, and environmental information of each apple tree in the orchard, and then regulate the growth environment of each apple tree in the orchard.

[0030] In a specific example, the analysis and regulation module includes: Branch analysis and regulation unit: It is used to analyze and obtain each branch to be pruned and each branch to be regulated according to the branch information of each apple tree in the orchard, and then regulate each branch to be pruned and each branch to be regulated of each apple tree.

[0031] Pest and disease analysis and regulation unit: It is used to predict the pests and diseases of each apple tree according to the pest and disease information of the orchard after the branch analysis and regulation are completed, and then regulate the pests and diseases of each apple tree according to the environmental information of the orchard.

[0032] In a specific example, for analyzing each branch to be pruned and each branch to be regulated based on the branch information of each apple tree in the orchard, and then regulating each branch to be pruned and each branch to be regulated of each apple tree, the specific process is as follows: Divide the branches of a certain apple tree into quadrats according to a preset length to obtain each area of the apple tree, and then use a camera device to collect the branch images of each area of the apple tree, so as to analyze the branch density of each area of the apple tree through image processing technology. Compare the branch density of each area of the apple tree with the standard density range of the apple tree branches set. When the branch density of a certain area of the apple tree is greater than the upper limit value of the standard density range, mark this area of the apple tree as a first-level regulation area. When the branch density of a certain area of the apple tree is less than the lower limit value of the standard density range of the apple tree branches set, mark this area of the apple tree as a second-level regulation area. At the same time, mark the middle value of the standard density range of the apple tree branches set as the density regulation threshold. When the branch density of a certain area of the apple tree belongs to the standard density range but is greater than the density regulation threshold, mark this area of the apple tree as a third-level regulation area. Based on this, obtain each first-level regulation area, each second-level regulation area, and each third-level regulation area of each apple tree in the orchard, and perform corresponding regulation on each first-level regulation area, each second-level regulation area, and each third-level regulation area.

[0033] It should be noted that the preset length is set by relevant staff according to the branch length of the apple tree.

[0034] It should be noted that the image processing technology is an existing technology, so it will not be elaborated here.

[0035] It should be noted that the standard density range of the apple tree branches is obtained by the staff's scientific research practice, production experience summary, and growth law research on the apple trees in the orchard, specifically 80,000 - 120,000 branches per mu.

[0036] After completing the regulation of each first-level regulation area, each second-level regulation area, and each third-level regulation area of each apple tree in the orchard, obtain any fruit tree, denoted as the target apple tree. Use a camera device to collect the images and videos of the target fruit tree and each adjacent apple tree, and then analyze the branch density at the branch junctions between the target apple tree and each adjacent apple tree through image processing technology. In the same way as analyzing each first-level regulation area, each second-level regulation area, and each third-level regulation area of each apple tree in the orchard, analyze each first-level adjacent regulation area, each second-level adjacent regulation area, and each third-level adjacent regulation area at the branch junctions between the target apple tree and each adjacent apple tree. Based on this, analyze each first-level adjacent regulation area, each second-level adjacent regulation area, and each third-level adjacent regulation area at the branch junctions between each apple tree and each adjacent apple tree, and perform corresponding regulation on each first-level adjacent regulation area, each second-level adjacent regulation area, and each third-level adjacent regulation area.

[0037] It should be noted that the regulation methods for correspondingly regulating each first-level adjacent regulation area, each second-level adjacent regulation area, and each third-level adjacent regulation area are the same as those for correspondingly regulating each first-level regulation area, each second-level regulation area, and each third-level regulation area; among them, correspondingly regulating each first-level regulation area, each second-level regulation area, and each third-level regulation area can not only ensure that each branch can carry out sufficient photosynthesis, but also reduce the ineffective consumption of nutrients and ensure the quality and taste of the fruits; correspondingly regulating each first-level adjacent regulation area, each second-level adjacent regulation area, and each third-level adjacent regulation area can not only reasonably allocate space, avoid the development problems of apple trees caused by space competition, but also make the passages in the orchard more unobstructed, facilitating the work of fruit farmers.

[0038] In a specific example, the process of correspondingly regulating each first-level regulation area, each second-level regulation area, and each third-level regulation area is as follows: for each first-level regulation area, obtain the intermediate value of the set standard density range of apple tree branches, denoted as the standard density of apple tree branches, and dispatch relevant staff to prune the branches in each first-level regulation area according to the standard density of apple tree branches.

[0039] For each second-level regulation area, obtain the standard light intensity range corresponding to the standard density range of apple tree branches from the data center, and the central control unit controls the supplementary lighting devices corresponding to each second-level regulation area in the orchard based on the light intensity threshold to supplement light to each second-level supplementary lighting area.

[0040] It should be noted that the standard light intensity range corresponding to the standard density range is obtained by the staff's scientific research practice, production experience summary, and growth law research on apple trees in the orchard. Specifically, it is 30%-60% of the natural light intensity at the top of the corresponding apple tree. Among them, the natural light intensity at the top of the apple tree is collected by the light sensor at the top of the corresponding apple tree. In order to obtain a more effective regulation effect, the supplementary lighting device can be controlled to supplement light to the corresponding second-level regulation areas according to 60% of the natural light intensity at the top of the corresponding apple tree.

[0041] For each third-level regulation area, if a third-level area is the top area of an apple tree, no regulation is performed on this third-level regulation area. If a third-level regulation area is not the top area of an apple tree, the current light intensity of this third-level regulation area is obtained through the light sensor at the apple tree branch, and the corresponding standard light intensity range of this third-level regulation area is analyzed. If the current light intensity of this third-level regulation area belongs to the standard light intensity range, no regulation is performed on this third-level regulation area. If the current light intensity of this third-level regulation area does not belong to the standard light intensity range, the central control unit controls the supplementary lighting device to regulate this third-level regulation area according to the lower limit value of the standard light intensity range. The regulation of each third-level regulation area in the orchard is carried out in this way.

[0042] In a specific example, after the branch analysis and regulation are completed, the apple trees are predicted for pests and diseases according to the pest and disease information of the orchard. The specific process is as follows: Obtain the content of each bacterium, each fungus, each virus and each pest collected by each soil information sensor and each air information sensor in the orchard from the central control unit. Denote the average values of the content of each bacterium, each fungus, each virus and each pest as the content of bacteria and fungi, the content of viruses and the content of pests in the orchard respectively. Compare the content of bacteria and fungi, the content of viruses and the content of pests in the orchard with the thresholds of the content of bacteria and fungi, the threshold of the content of viruses and the threshold of the content of pests respectively. If the content of bacteria and fungi, the content of viruses and the content of pests in the orchard are all less than the corresponding thresholds of the content of bacteria and fungi, the threshold of the content of viruses and the threshold of the content of pests, no pest and disease regulation is required for the orchard. Otherwise, according to the comparison of the content of bacteria and fungi, the content of viruses and the content of pests in the orchard with the corresponding thresholds of the content of bacteria and fungi, the threshold of the content of viruses and the threshold of the content of pests, the types of pests and diseases in the orchard are predicted.

[0043] It should be noted that the thresholds of the content of bacteria and fungi, the threshold of the content of viruses and the threshold of the content of pests are determined by the specific types of bacteria and fungi, viruses and pests. For example, the threshold of the content of Colletotrichum gloeosporioides spores is 10 5 spores per milliliter, and the threshold of the content of Cydia pomonella is 1 adult per square meter, etc.

[0044] It should be noted that predicting the types of pests and diseases in the orchard according to the comparison of the content of bacteria and fungi, the content of viruses and the content of pests in the orchard with the corresponding thresholds of the content of bacteria and fungi, the threshold of the content of viruses and the threshold of the content of pests specifically includes: When the content of bacteria and fungi in the orchard is greater than or equal to the corresponding threshold of the content of bacteria and fungi, but the content of viruses and the content of pests are less than the corresponding thresholds of the content of viruses and the content of pests, the type of pests and diseases in the orchard is predicted as bacteria and fungi infection. The orchard is predicted for virus infection and pest infection in this way.

[0045] In a specific example, the regulation of pests and diseases in the orchard is carried out as follows: When the predicted type of pests and diseases in the orchard is bacterial and fungal infections, obtain the specific types of bacteria and fungi predicted to be infected, and then obtain the unsuitable temperature and unsuitable light conditions of the predicted infected bacteria and fungi. According to the unsuitable temperature and unsuitable light conditions of the predicted infected bacteria and fungi, control the light supplement device and the temperature compensation device to control the bacteria and pathogens in the orchard at a preset frequency, and at the same time dispatch workers to spray relevant biological inhibitors in the orchard.

[0046] When the predicted type of pests and diseases in the orchard is virus infection, obtain the specific type of virus predicted to be infected, and then obtain the unsuitable temperature and unsuitable light conditions of the predicted infected virus. According to the unsuitable temperature and unsuitable light conditions of the predicted infected virus, control the light supplement device and the temperature compensation device to disinfect the virus in the orchard at a preset frequency, and at the same time introduce corresponding beneficial microorganisms to inhibit the virus in the orchard.

[0047] When the predicted type of pests and diseases in the orchard is pest infection, obtain the specific type of pests predicted to be infected, and then obtain the unsuitable temperature and unsuitable light conditions of the predicted infected pests. According to the unsuitable temperature and unsuitable light conditions of the predicted infected pests, control the light supplement device and the temperature compensation device to disinfect the pests in the orchard at a preset frequency, and at the same time plant nectar plants and trapping plants in the orchard, so as to provide habitats and breeding places for the natural enemy insects of the pests, and then inhibit the pests in the orchard.

[0048] When the predicted type of pests and diseases in the orchard is a combined infection of multiple types such as bacterial and fungal infections, virus infections, and pest infections, comprehensively control the pests and diseases in the orchard based on the control methods for each infection type of the pests and diseases in the orchard.

[0049] It should be noted that the preset frequency is determined by relevant staff. Among them, controlling the light supplement device and the temperature compensation device to control the pests and diseases in the orchard at a preset frequency avoids the impact on the growth of apple trees caused by the mechanical energy of continuously controlling the light supplement device and the temperature compensation device for pest control.

[0050] It should be noted that comprehensively control the pests and diseases in the orchard based on the control methods for each infection type of the pests and diseases in the orchard. For example, when the predicted type of pests and diseases in the orchard is virus and pest infections, introduce corresponding beneficial microorganisms to inhibit the virus in the orchard, and at the same time plant nectar plants and trapping plants in the orchard, so as to provide habitats and breeding places for the natural enemy insects of the pests, and then inhibit the pests in the orchard, and adjust the temperature and light accordingly to achieve the control of pests and diseases in the orchard.

[0051] Regulation feedback module: It is used to count the apple yield in the orchard after fruit picking, and then evaluate the regulation effect of the growth environment of apple trees in the orchard.

[0052] The process of evaluating the regulation effect of the growth environment of apple trees in the orchard is as follows: Obtain the apple yield of each historical planting cycle of the orchard and the number of times apple trees are affected by pests and diseases in each historical planting cycle from the data center. Compare the apple yield and the number of times apple trees are affected by pests and diseases counted in the current cycle with the apple yield and the number of times apple trees are affected by pests and diseases in each historical cycle of the orchard respectively. If the apple yield in the orchard in the current cycle is greater than the apple yield in any historical cycle, it indicates that the regulation of the branches of each apple tree in the orchard is effective; otherwise, it indicates that the regulation of the branch density in the orchard is ineffective. Similarly, if the number of times each apple tree in the orchard is affected by pests and diseases in the current cycle is 0 or less than the number of times apple trees are affected by pests and diseases in any historical cycle, it indicates that the regulation of pests and diseases in the orchard is effective; otherwise, it indicates that the regulation of pests and diseases in the orchard is ineffective. Then, feedback the result to the relevant staff.

[0053] Refer to Figure 2 As shown, this application provides an intelligent regulation method for the growth environment of apple trees, including the following steps: Step 1, Intelligent regulation network: It is used to build an intelligent regulation network in the orchard to realize the intelligent regulation of the growth environment of each apple tree in the orchard.

[0054] Step 2, Apple tree monitoring: It is used to monitor the branch information, pest and disease information, and environmental information of each apple tree in the orchard, obtain the branches of each apple tree at all levels, and transmit the monitoring and acquisition results to the central control unit.

[0055] Step 3, Analysis and regulation: It is used to analyze the branch information, pest and disease information, and environmental information of each apple tree in the orchard, and then regulate the growth environment of each apple tree in the orchard.

[0056] Step 4: Regulation feedback module: It is used to count the apple yield in the orchard after fruit picking, and then evaluate the regulation effect of the growth environment of apple trees in the orchard.

[0057] This application connects various sensors in the orchard to the central control unit through wireless sensing technology, realizing the automation and intelligence of orchard management, reducing the workload of manual monitoring and operation, and collecting the branch information, pest and disease information, and environmental information of each apple tree in the orchard through the installed sensors. Furthermore, the branch density of the apple trees is regulated according to the branch information of each apple tree, effectively reducing the branch density to ensure light and ventilation, enhancing photosynthesis, reducing the humidity in the orchard, inhibiting the growth of pathogens. After the branch regulation is completed, the orchard pests and diseases are regulated according to the pest and disease information and environmental information in the orchard. From the perspectives of light and temperature, biological inhibitors and natural enemy insects are used to inhibit the pests and diseases, avoiding blind use of pesticides and improving the control effect.

[0058] The above content is only an example and illustration of the concept of this application. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the concept of the invention or exceed the scope defined by this application, they should fall within the protection scope of this application.

The central control unit controls the fill light device corresponding to each secondary control area in the orchard based on the light intensity threshold, and fills light for each secondary fill light area; For each three-level control area, if a third-level area is the top area of ​​the apple tree, the third-level control area will not be regulated; if a third-level control area is not the top area of ​​the apple tree, the current light intensity of the three-level control area is obtained by the light sensor at the branch of the apple tree, and the standard light intensity range corresponding to the three-level control area is obtained by analysis; if the current light intensity of the three-level control area belongs to the standard light intensity range, the three-level control area will not be regulated; if the current light intensity of the three-level control area does not belong to the standard light intensity range, the central control unit controls the fill light device to regulate the three-level control area according to the lower limit value of the standard light intensity range, and each three-level control area in the orchard is regulated in this way.

7. The growth environment intelligent control system for the growth state of an apple tree according to claim 6, characterized in that: After the branch analysis and regulation are completed, pest and disease prediction is performed on each apple tree according to the pest and disease information of the orchard. The specific process is as follows: The bacterial and fungal contents, viral contents and pest contents collected by the soil information sensors and the air information sensors in the orchard are obtained from the central control unit, and the average values ​​of the bacterial and fungal contents, viral contents and pest contents are recorded as the bacterial and fungal contents, viral contents and pest contents in the orchard, respectively. The bacterial and fungal contents, viral contents and pest contents in the orchard are compared with the bacterial and fungal content thresholds, viral content thresholds and pest content thresholds, respectively. If the bacterial and fungal contents, viral contents and pest contents in the orchard are all less than the corresponding bacterial and fungal content thresholds, viral content thresholds and pest content thresholds, there is no need to carry out disease and pest control in the orchard. Otherwise, the types of diseases and pests in the orchard are predicted based on the comparison between the bacterial and fungal contents, viral contents and pest contents in the orchard and the corresponding bacterial and fungal content thresholds, viral content thresholds and pest content thresholds.

8. The growth environment intelligent control system for the growth state of an apple tree according to claim 7, characterized in that: The specific process of controlling pests and diseases in orchards is as follows: When the orchard pests and diseases are predicted to be bacterial and fungal infections, the specific predicted infected bacteria and fungi types are obtained, and then the unsuitable temperature and unsuitable light conditions of the predicted infected bacteria and fungi are obtained. According to the predicted unsuitable temperature and unsuitable light conditions of the predicted infected bacteria and fungi, the light supplement device and the temperature compensation device are controlled to control the bacteria and pathogens in the orchard at a preset frequency, and staff are dispatched to spray relevant biological inhibitors in the orchard; When the type of pests and diseases in the orchard is predicted to be a virus infection, the specific predicted virus type is obtained, and then the unsuitable temperature and unsuitable light conditions of the predicted infected virus are obtained, and the fill light device and the temperature compensation device are controlled according to the unsuitable temperature and unsuitable light conditions of the predicted infected virus to disinfect the virus in the orchard at a preset frequency, and corresponding beneficial microorganisms are introduced to inhibit the virus in the orchard; When the orchard's pest type is predicted to be a pest infection, the specific predicted infected pest type is obtained, and then the unsuitable temperature and unsuitable light conditions of the predicted infected pests are obtained, and the supplementary light device and the temperature compensation device are controlled to disinfect the pests in the orchard at a preset frequency according to the unsuitable temperature and unsuitable light conditions of the predicted infected pests, and at the same time, nectar plants and attractant plants are planted in the orchard, thereby providing a habitat and breeding place for the natural enemy insects of the pests, thereby suppressing the pests in the orchard; When the types of pests and diseases in an orchard are predicted to be a complex infection of multiple types including bacterial and fungal infections, viral infections and pest infections, pests and diseases in the orchard are controlled comprehensively based on control methods for each infection type of the pests and diseases in the orchard.

9. The growth environment intelligent control system for the growth state of an apple tree according to claim 8, characterized in that: The specific process of evaluating the effect of regulating the growth environment of apple trees in the orchard is as follows: The apple yield of each historical planting cycle and the number of apple tree diseases and pests in each historical planting cycle are obtained from the data center. The apple yield and the number of apple tree diseases and pests in the orchard in the current cycle are compared with the apple yield and the number of apple tree diseases and pests in each historical cycle of the orchard. If the apple yield in the orchard in the current cycle is greater than the apple yield in any historical cycle, it means that the branch regulation of each apple tree in the orchard is effective; otherwise, it means that the branch density regulation of the orchard is ineffective. Similarly, if the number of apple tree diseases and pests in the orchard in the current cycle is 0 or less than the number of apple tree diseases and pests in any historical cycle, it means that the disease and pest regulation of the orchard is effective; otherwise, it means that the disease and pest regulation of the orchard is ineffective. The results are fed back to relevant staff.
