A method and system for controlling irrigation and fertilization throughout the entire growth cycle of greenhouse vegetables

Abstract

This invention discloses a method and system for controlling irrigation and fertilization throughout the entire growth cycle of greenhouse vegetables. The system receives initial parameters and generates an initial irrigation and fertilization plan based on these parameters. It extracts irrigation and fertilization nodes from the initial plan to generate adjustment nodes. The system irrigates and fertilizes the soil according to the initial plan, collects field data, and analyzes the data. If the soil moisture value is below the water stress point, it determines whether a temporary irrigation plan needs to be generated. If a temporary irrigation plan exists, it is executed first; otherwise, the initial irrigation and fertilization plan is followed. The system fine-tunes the current initial irrigation and fertilization plan and operates according to the adjusted plan. This allows the system to adapt to different growth cycles of different vegetables, flexibly irrigating and fertilizing based on the actual growth conditions of the vegetables, as well as the soil and greenhouse environment, thereby promoting vegetable growth and increasing vegetable yield while conserving water resources.

Description

Technical Field

[0001] This invention relates to the field of vegetable irrigation technology, specifically to a method and system for controlling irrigation and fertilization throughout the entire growth cycle of greenhouse vegetables. Background Technology

[0002] With the increasing demand for vegetables, greenhouse vegetable cultivation has become an important means of ensuring vegetable supply. Irrigation and fertilization are key factors affecting vegetable yield, quality, and economic benefits in greenhouse vegetable cultivation. With technological advancements, intelligent irrigation and integrated water and fertilizer systems are becoming increasingly common, replacing manual irrigation and fertilization and greatly improving production efficiency. However, because different vegetable varieties, growth stages, and temperatures have varying requirements for water and nutrients, automated irrigation struggles to meet these diverse needs, resulting in poor overall flexibility and an inability to adequately meet the growth requirements of vegetables. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a method and system for controlling irrigation and fertilization throughout the entire growth cycle of greenhouse vegetables.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A method for controlling irrigation and fertilization throughout the entire growth cycle of greenhouse vegetables, including the following steps:

[0006] Receive initial parameters, including irrigated area, soil type, vegetable type, and start time;

[0007] Match the corresponding planting requirements based on the initial parameters, and generate an initial irrigation and fertilization plan based on the planting requirements;

[0008] Extract the irrigation nodes and fertilization nodes from the initial irrigation and fertilization plan, and set adjustment nodes corresponding to the irrigation nodes and fertilization nodes;

[0009] Extract the first plan from the initial irrigation and fertilization plan in sequence, and irrigate and fertilize the soil according to the settings of the first plan.

[0010] After completing the first plan, collect field data and evaluate the field data. When the soil moisture value in the field data is lower than the water stress point, determine whether a temporary irrigation plan needs to be generated.

[0011] When there is a temporary irrigation plan, implement the temporary irrigation plan first; when there is no temporary irrigation plan, proceed according to the initial irrigation and fertilization plan.

[0012] When the adjustment node is reached, the current field data and weather data are obtained. Based on the field data and weather data, the current initial irrigation and fertilization plan is fine-tuned and carried out according to the fine-tuned irrigation and fertilization plan.

[0013] In this invention, preferably, determining whether a temporary irrigation plan needs to be generated includes:

[0014] Get weather data for the next week;

[0015] Determine if there is rain in the weather data; if there is rain, do not generate a temporary irrigation plan.

[0016] When there is no rainfall, calculate the interval between the time corresponding to the occurrence of the lower limit value and the time corresponding to the planned irrigation and fertilization application.

[0017] If the interval exceeds the set period, a temporary irrigation plan will be generated. The time of the temporary irrigation plan is the current time, and the irrigation amount is calculated according to the irrigation formula corresponding to different growth nodes.

[0018] In this invention, preferably, when the adjustment node corresponding to the fertilization node is reached, it is determined whether the vegetable has reached the corresponding growth node; if the growth node has not been reached, the fertilization node is delayed.

[0019] In this invention, preferably, when a fertilization node is reached, growth data and image data of the corresponding vegetable growth node are provided based on the growth node of the vegetable corresponding to the fertilization node.

[0020] In this invention, preferably, when the adjustment node corresponding to the irrigation node is reached, the soil root zone moisture and the crop coefficient of the current node are obtained (the current node is the actual growth node reached by the vegetables). When the soil root zone moisture is greater than the preset value, the irrigation plan of the adjustment node is delayed. When the soil root zone moisture is within the preset range, the irrigation plan is carried out again.

[0021] In this invention, preferably, the first plan in the initial irrigation and fertilization plan is to perform initial irrigation, and the amount of water for the initial irrigation is:

[0022]

[0023] ,

[0024] ,

[0025] In the formula, RAW represents the initial irrigation volume, and RAW represents the depth of available soil moisture in the root zone. For loss rate, For effective soil moisture in the root zone, Soil moisture content, The soil moisture content at the wilting point. This represents the maximum root depth.

[0026] A greenhouse vegetable full-cycle irrigation and fertilization control system, including

[0027] The data acquisition unit includes a soil moisture sensor, a temperature sensor, an air humidity sensor, a soil nutrient sensor, and a meteorological monitoring station.

[0028] Multiple soil moisture sensors are installed at different vertical depths in the soil to collect soil moisture content at different depths, depending on the root and stem depth of different vegetables.

[0029] Temperature and humidity sensors are used to collect data on temperature and humidity inside the greenhouse.

[0030] Soil nutrient sensors are used to collect data on the nitrogen, phosphorus, and potassium content in soil.

[0031] The meteorological monitoring station is set up outside the greenhouse to collect meteorological data on temperature, humidity, light intensity, and wind speed outside the greenhouse;

[0032] An irrigation unit, comprising a water pump, pipes, sprinklers, and capillary tubes, is evenly distributed throughout the irrigation area.

[0033] The fertilization unit is connected to the irrigation unit. The fertilization unit includes a fertilizer storage tank, a metering pump and a transport pipeline. The metering pump mixes a certain amount of fertilizer with water and sprays it through nozzles.

[0034] The main control unit is communicatively connected to the acquisition unit, irrigation unit, and fertilization unit for data exchange. The main control unit also includes an initial parameter setting module, an initial plan generation module, a monitoring module, a temporary plan generation module, an adjustment module, an execution module, and a storage module.

[0035] The initial parameter setting module is used to set the current irrigated area, soil type, and vegetable crop type.

[0036] The initial plan generation module generates an initial irrigation and fertilization plan from the storage module based on the initial data transmitted by the initial parameter setting module, matching the requirements.

[0037] The initial irrigation and fertilization plan is transmitted to the execution module, which controls the irrigation unit and the fertilization unit to perform irrigation and fertilization according to the initial irrigation and fertilization plan;

[0038] After the first plan is completed, the data collection unit collects on-site data and sends it to the monitoring module. The monitoring module compares the data in real time to determine whether the soil moisture value is lower than the water stress point and whether the vegetables have reached the growth node. When the soil moisture value is lower than the water stress point, the temporary plan generation module is triggered to generate a temporary irrigation plan. When the vegetables have not reached the growth node during the adjustment, the plan is sent to the execution module, which delays the execution of the current fertilization plan.

[0039] The adjustment module sets adjustment nodes according to the initial irrigation and fertilization plan. When the adjustment node is reached, it acquires on-site data, weather data, and actual growth node data. Based on the real-time data, it determines whether the initial irrigation and fertilization plan needs to be adjusted and sends the result to the execution module.

[0040] The storage module stores soil types and corresponding soil data, vegetable types and related parameters for each type, including growth nodes, maximum root depth, loss rate, initial coefficient, and vegetable crop coefficients at each growth node.

[0041] In this invention, preferably, a reference unit and a display unit are also included. The reference unit stores vegetable growth data and image data at each growth node for all vegetable varieties. At each adjustment node, the corresponding current growth data and image data of the vegetable are sent to the display unit for display and reference comparison.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] The irrigation and fertilization method of the present invention can adapt to different growth cycles of different vegetables, and flexibly irrigate and fertilize according to the actual growth of vegetables and the soil and greenhouse environment, thereby promoting vegetable growth and increasing vegetable yield; at the same time, it saves water resources.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] Please see Figure 1 A preferred embodiment of the present invention provides a method for controlling irrigation and fertilization throughout the entire growth cycle of greenhouse vegetables, comprising the following steps:

[0049] Receive initial parameters, including irrigated area, soil type, vegetable type, and start time;

[0050] Match the corresponding planting requirements based on the initial parameters, and generate an initial irrigation and fertilization plan based on the planting requirements;

[0051] Extract the irrigation nodes and fertilization nodes from the initial irrigation and fertilization plan, and set adjustment nodes corresponding to the irrigation nodes and fertilization nodes;

[0052] Extract the first plan from the initial irrigation and fertilization plan in sequence, and irrigate and fertilize the soil according to the settings of the first plan.

[0053] After completing the first plan, collect field data and evaluate the field data. When the soil moisture value in the field data is lower than the water stress point, determine whether a temporary irrigation plan needs to be generated.

[0054] When there is a temporary irrigation plan, implement the temporary irrigation plan first; when there is no temporary irrigation plan, proceed according to the initial irrigation and fertilization plan.

[0055] When the adjustment node is reached, the current field data and weather data are obtained. Based on the field data and weather data, the current initial irrigation and fertilization plan is fine-tuned and carried out according to the fine-tuned irrigation and fertilization plan.

[0056] Specifically, initial parameters are determined based on actual planting needs. Irrigation area is set according to actual conditions; soil types include sandy soil, sandy loam, loamy sandy soil, loam, silty loam, silt, silty clay loam, silty clay, and clay; vegetable types include cabbage, kale, small leafy vegetables, large leafy vegetables, radishes and root vegetables, solanaceous vegetables, cucurbits, and beans; start time is set according to actual conditions. Different types correspond to different planting, irrigation, and fertilization requirements.

[0057] Based on the determined soil type and vegetable variety, planting requirements are matched accordingly. An initial irrigation and fertilization plan is generated based on the planting requirements. The initial irrigation and fertilization plan includes irrigation time, fertilization time, irrigation water volume, fertilizer type and fertilizer amount. The initial irrigation and fertilization plan coordinates the entire cycle of vegetable growth management and makes preparations for irrigation volume and fertilization in advance.

[0058] The irrigation and fertilization nodes in the initial irrigation and fertilization plan are extracted. Generally, the irrigation and fertilization nodes are related to the growth stages of vegetables. The extracted irrigation and fertilization nodes are used as adjustment nodes to avoid the initial irrigation and fertilization plan from not matching the actual growth of vegetables, ensuring that the timing of irrigation and fertilization is correct, which is conducive to promoting the development and growth of vegetables.

[0059] The initial irrigation and fertilization plan, based on adjustment nodes and arranged chronologically, includes several sub-plans. The first plan is the initial irrigation plan, which is calculated solely based on soil type, soil moisture content, and vegetable type. The irrigation amount for the first plan is:

[0060] ,

[0061] ,

[0062] ,

[0063] In the formula, RAW represents the initial irrigation volume, and RAW represents the depth of available soil moisture in the root zone. For loss rate, This refers to the effective soil moisture depth in the root zone. Soil moisture content, The soil moisture content at the wilting point. This represents the maximum root depth.

[0064] Table 1 below shows the soil moisture content and wilting point soil moisture content values ​​for different soil types. Table 2 shows the maximum root depth and loss rate for different vegetable varieties. Based on this formula, the initial irrigation amount for different vegetable varieties under different soil conditions can be accurately determined, laying a good foundation for vegetable growth.

[0065] Table 1

[0066]

[0067] Table 2

[0068]

[0069] In this embodiment, determining whether a temporary irrigation plan needs to be generated includes:

[0070] Get weather data for the next week;

[0071] Determine if there is rain in the weather data; if there is rain, do not generate a temporary irrigation plan.

[0072] When there is no rainfall, calculate the interval between the time corresponding to the occurrence of the lower limit value and the time corresponding to the planned irrigation and fertilization application.

[0073] If the interval exceeds the set period, a temporary irrigation plan will be generated. The time of the temporary irrigation plan is the current time, and the irrigation amount is calculated according to the irrigation formula corresponding to different growth nodes.

[0074] For vegetables whose growth nodes are in the germination stage, the temporary irrigation amount is calculated according to the following formula:

[0075] ;

[0076] In the formula, S represents the planting area. The depth of available soil moisture in the root zone. The target soil moisture content, This represents the current soil moisture content.

[0077] For vegetables in the seedling stage, the amount of temporary irrigation is calculated using the following formula:

[0078]

[0079] In the formula, S represents the planting area. This refers to the transpiration and evaporation of vegetables during the seedling stage. This represents the number of days since the initial irrigation and fertilization plan was implemented; round down to the nearest integer.

[0080] For vegetables whose growth nodes are within the mature stage, the amount of temporary irrigation is calculated according to the following formula:

[0081]

[0082] In the formula, For temporary irrigation water volume, This refers to the transpiration and evaporation of vegetables. S represents the vegetable crop coefficient, and S represents the planting area. This refers to the number of days remaining until the planned irrigation and fertilization.

[0083] For vegetables whose growth nodes are during the flowering period, the amount of temporary irrigation is calculated according to the following formula:

[0084]

[0085]

[0086] In the formula, For temporary irrigation water volume, This refers to the relative humidity of the air. This represents the actual temperature inside the greenhouse. The optimal temperature for vegetable flowering period. The basic watering amount is given by S, where S represents the planting area. This refers to the number of flowers per vegetable plant. This represents the water requirement coefficient for flowers.

[0087] For vegetables whose growth nodes are within the fruiting period, the amount of temporary irrigation is calculated according to the following formula:

[0088]

[0089] In the formula, S represents the fruit enlargement rate, and S represents the planting area. The depth of available soil moisture in the root zone. The water supply coefficients for different soil types.

[0090] Specifically, the coefficients related to vegetables mentioned above are obtained by retrieving the corresponding parameters of various vegetables at different growth stages stored in the storage module. Real-time parameters are retrieved from the field data. By distinguishing different growth stages, the temporary irrigation needs of vegetables at different growth cycles can be met. Combined with the actual situation, such as the specific vegetable type, soil type, actual soil moisture, and humidity at the start of the construction period, precise irrigation is achieved to ensure that vegetables receive a suitable water supply.

[0091] In this embodiment, when the adjustment node corresponding to the fertilization node is reached, it is determined whether the vegetable has reached the corresponding growth node. If the growth node has not been reached, the fertilization node is delayed.

[0092] Specifically, growth nodes can be identified by setting up video data acquisition equipment and extracting actual vegetable growth images through simple image processing. This allows for the determination of the vegetable's current growth stage. The data can then be manually assessed and used as feedback. Manual assessment is more accurate and less costly.

[0093] In this embodiment, when the fertilization node is reached, the growth data and image data of the corresponding vegetable growth node are provided based on the growth node of the vegetable corresponding to the fertilization node, so as to provide a reference for personnel. For those who are not familiar with the vegetable growth, the growth node of the vegetable can also be obtained through the growth data and image data, which is convenient to operate and easy to implement.

[0094] Meanwhile, determining the growth stage is crucial for implementing the fertilization plan. Fertilization is generally carried out according to the different fertilizer requirements of vegetables at different growth stages. Fertilizing too early or too late will affect vegetable growth, so feedback on the growth stage is necessary. When it is determined that vegetables have entered a new growth stage ahead of schedule, this is used as on-site data and fed back. Upon receiving this feedback, the fertilization plan to be implemented is retrieved and executed ahead of schedule.

[0095] In this embodiment, when the adjustment node corresponding to the irrigation node is reached, the soil root zone moisture and the crop coefficient of the current node are obtained. The current node is the actual growth node reached by the vegetables. When the soil root zone moisture is greater than the preset value, the irrigation plan of the adjustment node is delayed. When the soil root zone moisture is within the preset range, the irrigation plan is carried out again.

[0096] Please see Figure 2 Another preferred embodiment of the present invention provides an irrigation and fertilization control system for the entire growth cycle of greenhouse vegetables, specifically including:

[0097] The data acquisition unit includes a soil moisture sensor, a temperature sensor, an air humidity sensor, a soil nutrient sensor, and a meteorological monitoring station.

[0105] The initial parameter setting module is used to set the current irrigated area, soil type, and vegetable crop type.

[0106] The initial plan generation module generates an initial irrigation and fertilization plan from the storage module based on the initial data transmitted by the initial parameter setting module, matching the requirements.

[0107] The initial irrigation and fertilization plan is transmitted to the execution module, which controls the irrigation unit and the fertilization unit to perform irrigation and fertilization according to the initial irrigation and fertilization plan;

[0108] After the first plan is completed, the data collection unit collects on-site data and sends it to the monitoring module. The monitoring module compares the data in real time to determine whether the soil moisture value is lower than the water stress point and whether the vegetables have reached the growth node. When the soil moisture value is lower than the water stress point, the temporary plan generation module is triggered to generate a temporary irrigation plan. When the vegetables have not reached the growth node during the adjustment, the plan is sent to the execution module, which delays the execution of the current fertilization plan.

[0109] The adjustment module sets adjustment nodes according to the initial irrigation and fertilization plan. When the adjustment node is reached, it acquires on-site data, weather data, and actual growth node data. Based on the real-time data, it determines whether the initial irrigation and fertilization plan needs to be adjusted and sends the result to the execution module.

[0110] The storage module stores soil types and corresponding soil data, vegetable types and related parameters for each type, including growth nodes, maximum root depth, loss rate, initial coefficient, and vegetable crop coefficients at each growth node.

[0111] In this embodiment, a reference unit and a display unit are also included. The reference unit stores vegetable growth data and image data at each growth node for all vegetable varieties. At each adjustment node, the corresponding current growth data and image data of the vegetable are sent to the display unit for display and reference comparison.

Based on this understanding, the technical solution of this invention, essentially, or the part that contributes to the prior art, or a portion of the technical solution, can be embodied in the form of a software product.
