Description

Technical Field

[0001] The present invention relates to the technical field of crop pest control, and in particular to a method and system for controlling crop diseases and insect pests. Background Art

[0002] Vegetable crops are essential foods in our daily lives. The yield of vegetables will directly affect the price of vegetables, thus affecting our dietary needs. In order to achieve high crop yields, it is necessary to prevent and control pests and diseases during the growth of crops. Since crop diseases and pests not only affect the economic benefits and stability of agricultural production, but may also pose a potential threat to the environment and human health. Therefore, the prevention and control of crop diseases and pests is an important part of agricultural production. Effective prevention and control measures can ensure the healthy growth of crops and high-yield and high-quality production.

[0003] However, the traditional means of pest control is to spray pesticides manually. Since it is difficult to control the appropriate amount of pesticide spraying, sprayers often use multiple spraying methods to control pests. Although the effect of killing insects can be achieved, it is easy to spray too little, resulting in pesticide residues. In fact, some pests can be killed by spraying appropriate pesticides in combination with other means. Therefore, how to construct an effective pest control method based on the actual situation of crops has become a problem that needs to be solved urgently.

[0004] Therefore, the present invention provides a method and system for controlling crop diseases and insect pests. Summary of the invention

[0072] In this example, each sampled image contains a complete crop plant;

[0073] In this example, the pest information includes information about crops being eaten or damaged by pests;

[0074] In this example, the control plan refers to an effective method for controlling pests and diseases on crops, including but not limited to physical control (including covering and isolating crops, setting pest traps, cutting off diseased crops, etc.), spraying pesticides, biological control (including introducing natural enemies, conducting microbial control, planting plant natural enemies, etc.), and cultural control (including: changing the crop planting structure, etc.);

[0075] In this example, the prevention and control cycle is 24 hours*3.

[0076] The working principle and beneficial effects of the above technical solution: In order to prevent crops from being damaged by pests and to ensure the quality of crops, samples and photographs are taken during the growth of crops. Objects in the sampled images are identified to determine whether the crops are damaged by pests and diseases, and crop pest and disease information is generated. The basic characteristics of the crops are then combined to analyze the level and type of pests and diseases suffered by the crops, so as to establish a corresponding prevention and control plan. Managers can carry out prevention and control work according to the prevention and control plan, and in the process of prevention and control, the prevention and control plan can be improved according to the prevention and control effects of crops in different prevention and control cycles. Therefore, managers can carry out subsequent prevention and control work according to the improved prevention and control plan, which effectively improves the effect and speed of prevention and control and ensures the growth of crops.

[0078] On the basis of Example 1, the method for controlling crop diseases and insect pests, the step 1, comprises:

[0079] Step 11: respectively obtain the standard contour corresponding to each crop, locate the planting area corresponding to each crop in the planting base according to the standard contour, and determine the sampling quantity of the corresponding crop according to the area corresponding to each planting area;

[0080] Step 12: obtaining randomly sampled crops in the corresponding planting area based on the standard outline and sampling quantity corresponding to each of the crops, photographing each of the randomly sampled crops respectively, and obtaining a plurality of frames of sampling images corresponding to each of the crops;

[0081] Step 13: respectively identifying leaf information contained in each of the sampled images, counting a number of leaf information corresponding to each of the crops, obtaining a number of leaf appearances presented by each of the crops, and determining whether the corresponding crops are affected by pests and diseases according to the leaf appearances;

[0082] Step 14: extract target crops affected by pests and diseases, perform pest and disease screening on the target crops, and establish pest and disease information corresponding to the target crops according to the screening results.

[0083] In this example, the relationship between the area and the number of samples is: one sample per square meter;

[0084] In this example, the leaf information represents the appearance information of the leaves of the crop;

[0085] In this example, the leaf appearance morphology represents the actual outline of the leaves of the crop.

[0086] The working principle and beneficial effects of the above technical solution are as follows: by locating the planting area of ​​crops and then sampling and photographing the crops based on the area of ​​the planting area, the accuracy of sampling and elimination of randomness can be ensured, and then the leaf information in the collected image can be identified, thereby clarifying the leaf appearance of the crops, and then judging whether the crops are affected by pests and diseases based on the leaf appearance, and finally screening the crops affected by pests and diseases, establishing their pest and disease information, and laying the foundation for subsequent prevention and control work.

[0087] Example 3

[0088] On the basis of Example 2, in the method for controlling crop diseases and insect pests, step 14 comprises:

[0089] Step 141: Count the appearance of damaged leaves corresponding to each target crop, trace the appearance of each damaged leaf, obtain the target sampling image corresponding to the appearance of each damaged leaf, and obtain the target planting area of ​​each target crop in the planting base;

[0090] Step 142: locating each corresponding target sampling image in each target planting area, obtaining a plurality of positioning points contained in each target planting area, and performing environmental sampling and crop sampling on each positioning point respectively to obtain corresponding environmental information and sampling information;

[0091] Step 143: obtaining several types of pests contained in the target sampling image, respectively retrieving preset adaptive planting environment information corresponding to each target crop, using the preset adaptive planting environment information to perform adaptive evaluation on the corresponding environmental information, and constructing pest and disease growth information based on the evaluation results and the growth environment corresponding to each pest type;

[0092] Step 144: extracting features from each of the sampled information to obtain a plurality of damage features corresponding to each of the target crops, and establishing damage presentation information corresponding to the target crops based on the feature quantity and feature value corresponding to each of the damage features;

[0093] Step 145: establishing zero pest and disease information for crops that are not affected by pests and diseases, and establishing pest and disease information based on the pest and disease susceptibility information and damage presentation information corresponding to each of the target crops.

[0094] In this example, each positioning point corresponds to a frame of sampled image;

[0095] In this example, the preset planting environment adaptation information refers to information input in advance about the planting environment adaptation of different crops;

[0096] In this example, the environmental information refers to information such as temperature, humidity, and light intensity of the growing environment of the crops;

[0097] In this example, the sampling information represents the appearance information of the crop;

[0098] In this example, the pest growth information indicates the reproduction efficiency of the pests under the environmental information.

[0099] The working principle and beneficial effects of the above technical solution: In order to achieve efficient prevention and control, it is necessary to ensure the effectiveness of sampling. Environmental sampling and crop sampling are carried out according to the appearance of the damaged leaves of the target crops and the target planting area of ​​the target crops, so as to obtain the corresponding environmental information and sampling information, further identify the type of pests contained in the target sampling image, analyze the easy growth information of the pests in the crop growth environment, and establish pest and disease information for the target crops in combination with the damaged presentation information of the target crops. At the same time, in order to ensure the integrity of the data, zero pest and disease information is established for crops that are not affected by pests and diseases. This can provide a reference for subsequent prevention and control work.

[0100] Example 4

[0101] On the basis of Example 1, the method for controlling crop diseases and insect pests, the step 2 comprises:

[0102] Step 21: determining a standard leaf state and a standard stem state of the corresponding crop according to the basic characteristics corresponding to each of the crops, and establishing a plurality of actual leaf states and a plurality of actual stem states corresponding to each of the crops based on the pest and disease information;

[0103] Step 22: obtaining the leaf damage degree corresponding to each different actual leaf state according to the leaf difference between each actual leaf state and the corresponding standard leaf state, and obtaining the stem damage degree corresponding to each actual stem state according to the stem difference between each actual stem state and the corresponding standard stem state;

[0104] Step 23: extracting the maximum leaf damage degree and the maximum stem damage degree corresponding to each of the crops, and calculating the discreteness between the damage degrees of several leaves corresponding to each crop and the corresponding maximum leaf damage degree to establish a leaf damage discrete table, and calculating the discreteness between the damage degrees of several stems corresponding to each crop and the corresponding maximum stem damage degree to establish a stem damage discrete table;

[0106] The working principle and beneficial effects of the above technical solution: Since there are many types of pests and diseases, and sometimes crops are affected by multiple different pests and diseases, but the appearance of crops when affected by different pests and diseases is different, the standard state of the crops is first determined according to the basic characteristics of the crops, and the actual state of the case crops is determined according to the pest and disease information, so as to determine the leaf damage degree and stem damage degree of the crops by comparison, and determine the pest and disease level by analyzing the discrete situation between different damage degrees and their corresponding maximum damage degrees, and determine the pest and disease type according to the leaf damage outline and stem damage outline. In this way, not only can the damage of the crops be checked in detail, but also the damage level and pest and disease type can be located.

[0107] Example 5

[0108] On the basis of Example 1, the method for controlling crop diseases and insect pests, the step 3 comprises:

[0109] Step 31: searching for a corresponding available solution according to the basic characteristics corresponding to each of the crops, and obtaining the achievable effects corresponding to each of the available solutions;

[0111] Step 33: adjusting the implementation intensity of the effective and available solutions according to the pest and disease level corresponding to each crop, adjusting the implementation duration of the effective and available solutions based on the pest and disease type, and obtaining and displaying the prevention and control solutions corresponding to each crop.

[0112] The working principle and beneficial effects of the above technical solution: In order to improve the prevention and control effect and ensure the quality of prevention and control, and at the same time ensure that the generated prevention and control plan is consistent with the actual situation of crops, available plans are found according to the basic characteristics of crops, and the achievable effects of the available plans are compared and analyzed with the effects to be achieved by crops, so as to determine the effective and available plans, and then use the pest and disease grade and pest and disease type to calibrate the implementation intensity and implementation time of the effective and available plans, so as to obtain a prevention and control plan suitable for the actual situation of the crop.

[0114] Based on Example 5, the crop disease and insect pest control method further includes:

[0115] Classifying the crops into damaged crops and non-damaged crops;

[0116] A control plan is established for the damaged crops and displayed, and a prevention plan is established for the non-damaged crops and displayed.

[0117] The working principle and beneficial effects of the above technical solution are as follows: different prevention and control measures are carried out for different crops, which achieves the effect of early prevention and rapid prevention and control.

[0118] Example 7

[0119] Based on Example 1, the method for controlling crop diseases and insect pests, the step 4 further includes:

[0120] Step 41: Retrieving corresponding control materials based on the solution requirements corresponding to each of the control solutions, and using the control materials to control pests and diseases on each of the crops;

[0121] Step 42: respectively collecting crop presentation difference information corresponding to each crop in adjacent prevention and control cycles, and establishing prevention and control effect information corresponding to the crop in different prevention and control cycles according to the crop presentation difference information;

[0122] Step 43: establishing a growth quality trend graph of the crop based on the control effect information, and when the growth quality trend of the crop is lower than a preset trend, analyzing the growth demand information of the crop according to the growth quality trend graph;

[0123] Step 44: adjusting the implementation intensity corresponding to the prevention and control plan based on the generated demand information, generating an updated prevention and control plan and displaying it.

[0124] In this example, the preset trend is input in advance, regarding the growth rates of different crops in different growth cycles.

[0125] The working principle and beneficial effects of the above technical solution: In order to further improve the effect of prevention and control, the corresponding prevention and control materials are first called up before prevention and control, so as to carry out prevention and control work, and the growth area of ​​the crops is analyzed during the prevention and control process. If the growth is slow, it means that the current prevention and control effect is not good and the implementation intensity needs to be strengthened. Otherwise, the implementation intensity needs to be weakened, thereby ensuring that the crops can maintain a good growth rate.
