With the development of modern agriculture, the demand for automation level improvement in the planting industry is increasing. However, the problems of water resource shortage, soil degradation, environmental pollution and the like are becoming more serious, and the traditional empirical and extensive water and fertilizer management mode is becoming difficult to succeed. Currently, simple automatic equipment is adopted for irrigation and fertilization of field crops in a large agricultural park, irrigation and fertilization amounts are determined empirically or in a timing and quantitative mode, scientific basis is lacked, and the requirements of crop yield increase and resource utilization optimization cannot be met. Even high-end equipment can only adapt to few crop types, and cannot realize the fine water and fertilizer management of different crops in a block. The existing large-scale irrigation area water and fertilizer control device in the market is high in cost, the decision basis is single, irrigation and fertilization are carried out only by taking soil moisture or single environmental parameters as the basis, and the management effect is not accurate.

In summary, the existing water and fertilizer management technology is difficult to adapt to the requirements of modern agriculture development in a mode of quantitatively irrigating and fertilizing through experience or according to a single environmental factor, and a new intelligent and precise water and fertilizer management technology must be developed to realize yield increase and resource optimization utilization of crops.

In view of the foregoing background description, those skilled in the art will appreciate that the problems occurring in the prior art, and it is evident that the following description of the embodiments of the present application, taken in conjunction with the accompanying drawings, refers to only a portion of the embodiments of the present application, and not to all of the embodiments.

The specific method comprises the steps of arranging cameras in a region to be fertilized, collecting crop images at regular time, removing noise by using an image processing technology, extracting crop characteristics, and judging information such as crop types, quantity, individual growth stages and the like in the images by comparing the crop characteristics with the crop images in a database. Therefore, the real-time monitoring of the growth dynamics of crops can be realized, and a reasonable fertilization scheme is formulated according to the actual growth conditions of the crops. Compared with the traditional mode of manually observing and judging the growth stage at regular intervals, the image recognition realizes all-weather automatic monitoring of crop growth, avoids errors of manual observation, improves monitoring efficiency, provides accurate and timely basis for subsequent fertilization decision, is favorable for scientifically and reasonably determining parameters such as time, quantity and the like of fertilization, and ensures that fertilization is more accurate and intelligent.

The method comprises the steps of arranging cameras in the field and collecting crop images at certain time intervals. Then the noise is removed by using an image processing algorithm, and a clear crop image is reserved. Therefore, the actual growth conditions of crops, such as the number of plants, the individual size, the leaf color condition and the like, can be captured regularly, and whether the crops have the symptom of malgrowth or not can be judged. Compared with manual regular observation, the method realizes all-weather automatic monitoring of crops, avoids subjective errors of manual observation, and improves detection efficiency. The obtained crop image can provide image basis for subsequent analysis of fertility status, judgment of whether irrigation and irrigation quantity are needed, accurate control of crop growth status is realized, and scientific and reasonable irrigation strategy is formulated.

S302, filtering and contour extraction processing is carried out on a crop growth image to obtain a crop contour image;

Compared with manual statistics and identification, the method can automatically and efficiently acquire comprehensive growth information of crops, and does not need a large amount of labor cost. The obtained information can evaluate the growth condition of crop groups, judge whether the conditions of uneven development exist, provide basis for the subsequent formulation of differential irrigation strategies, and realize accurate control of crop fertility.

S304, determining the growth stage of the whole crop in the area to be fertilized according to the crop type, the number of crop plants and the growth stage of each crop plant.

Specifically, the overall growth stage is determined according to the identified crop type, plant number and each plant growth stage, so as to comprehensively evaluate the growth condition of the crop population. The specific method comprises the following steps:

Thus, individual plant information can be evaluated, whether the crop population grows uniformly, whether individuals with retarded development exist or not, and a stage which can represent the overall growth progress of the current crop can be determined. Compared with the method for estimating the growth stage according to time only, the method can determine the whole stage based on the actual growth condition of crops, realize accurate control of the growth dynamics of the crops, and provide scientific basis for the follow-up formulation of fertilization strategies.

S102, acquiring first weather data, the fertilizer content of the first soil and the first soil water content in a preset time period of a region to be fertilized, and determining target fertilization interval time according to the first weather data, the fertilizer content of the first soil, the first soil water content and the growth stage of crops;

Specifically, the first weather data, the crop growth stage, the first soil fertilizer content and the water content are obtained to fully consider the climate, the crop state and the soil nutrition condition, and the reasonable fertilization interval time is scientifically determined. The specific method is that meteorological equipment is arranged in a target area, data such as temperature, humidity and rainfall are collected, and meanwhile, the water content and the nutrient residual quantity of soil are detected. And (3) combining the crop growth stage obtained by image recognition, calculating the water consumption and fertilizer demand according to the absorption rule of the crop on water and nutrients, and determining the time interval for supplementing water and nutrients, namely the target fertilization interval time. Therefore, the fertilizing period can be flexibly adjusted according to the actual condition of crops and the nutritional condition of soil, so that not only is the resource waste caused by too frequent use avoided, but also the insufficient nutrition caused by too long interval time is prevented, the intelligent control of the growth period of the crops is realized, and the fertilizing plan is more scientific and reasonable, and the pertinence is stronger.

It should be noted that, the preset time period is a preset time period, and in a specific embodiment, weather data of five days in the future is mostly adopted.

S201, determining a first water consumption speed based on first weather data and a growth stage of crops;

specifically, the first water consumption speed is determined according to the first weather data and the crop growth stage, so as to evaluate the water consumption change trend of different growth stages under different climatic conditions. The specific method is to inquire the standard water consumption curve of the crops in each growth stage and calculate the actual water consumption rate of the growth stage by combining the obtained weather parameters such as the actual air temperature, the humidity, the illumination and the like. For example, high temperature weather can cause crops to consume water at an accelerated rate, and the increased water consumption can be estimated through calculation. Therefore, the accurate water consumption rate can be calculated based on the physiological characteristics of crops and the actual climate conditions, and a basis is provided for the subsequent determination of the water supplementing amount. Compared with the empirical water consumption value of the simply used crop growth stage, the water consumption rate combined with the actual climate factors is more targeted, can reflect the actual water demand dynamic change condition of crops under different climates, and has an important guiding function for the subsequent establishment of a reasonable water supplementing strategy.

S202, determining a first fertilization interval time based on a first water consumption speed and a first soil water content;

specifically, the first fertilization interval time is determined according to the first water consumption speed and the first soil water content, so that the water replenishing period is intelligently arranged in combination with the actual soil water content. The specific method comprises the steps of detecting or collecting water content data of first soil after the first water consumption speed is obtained, and dividing the water content of the soil by the first water consumption speed to calculate the time length for the crops to maintain growth under the current soil water content condition, namely the first fertilization interval time. Therefore, the time for supplementing water can be scientifically judged, irrigation is carried out before the soil water is insufficient to meet the growth requirement of crops, the resource waste caused by random irrigation can be avoided, and the crop water deficiency caused by blindly prolonging the interval time can be prevented. Compared with the traditional mode of judging the water supplementing period through experience, the method can actively arrange an irrigation plan according to the water demand condition of crops, and accurate supplementing of soil moisture is achieved.

S203, determining the fertilizer consumption speed based on the first weather data and the growth stage of crops;

specifically, the fertilizer consumption rate is determined according to the first weather data and the crop growth stage, so as to evaluate the nutrition consumption change condition of different growth stages under different climates. The specific method is to inquire standard fertilizer demand curves of crops in each growth stage, establish climate influence coefficient functions by combining parameters such as actual air temperature, illumination and the like, and calculate actual fertilizer consumption rate in the growth stage. For example, high temperatures can accelerate fertilizer losses and calculations can evaluate increased fertilizer demand. Therefore, the accurate fertilizer consumption rate can be calculated based on the physiological characteristics of crops and the actual climate conditions, and a basis is provided for the follow-up determination of the nutrition supplement. Compared with the method which simply adopts an empirical fertilizer requirement value, the method can reflect the actual nutritional requirement change condition of crops under different climates, and has a guiding effect on the subsequent establishment of a reasonable fertilizer application strategy.

S204, determining a second fertilization interval time based on the fertilizer consumption speed, the growth stage of crops and the fertilizer content of the first soil;

specifically, the second fertilization interval time is determined according to the fertilizer consumption speed, the crop growth stage and the first soil fertilizer content, so as to reasonably arrange a time node for supplementing the fertilizer. The specific method comprises the steps of detecting or collecting the fertilizer content data of the first soil after the fertilizer consumption speed is obtained, and then calculating the time required for the crops to grow to the next growing stage under the current soil nutrient condition, namely the second fertilizer application interval time. Therefore, the time for supplementing the fertilizer next time can be intelligently judged according to the growth dynamics of crops and the residual situation of soil nutrients, and the fertilizer is applied before the soil nutrients are insufficient to meet the growth requirements of the crops, so that the resource waste caused by random fertilizer application can be avoided, and the nutrient deficiency caused by the prolonged interval time can be prevented. Compared with the traditional fertilizer supplementing method based on experience, the method can more scientifically and reasonably arrange the fertilizer application period, and realize the active supplementing of the fertilizer requirement of crops.

S205, determining a target fertilization interval time based on the first fertilization interval time and the second fertilization interval time.

Specifically, the target fertilization interval time is determined according to the first fertilization interval time and the second fertilization interval time, so as to comprehensively consider soil moisture and nutrition conditions, and scientifically formulate a unified fertilization period scheme. The specific method is to compare the time interval of the two, and take the shorter time interval as the target fertilization interval time. Thus, the requirement of crops on moisture and the requirement of crops on nutrients can be met within the time interval. If one with longer time interval is directly adopted, the other nutrient can not meet the growth requirement of crops in the period of time, and normal fertility is affected. The adoption of shorter time interval can avoid the above-mentioned condition, not only can reasonably supplement water according to soil water condition, but also can timely supplement fertilizer according to soil nutrition condition, can implement balanced nutrient supply for crops and can promote crops to obtain good growth.

On the basis of the above embodiment, as an alternative embodiment, determining the target fertilization interval time based on the first fertilization interval time and the second fertilization interval time includes:

Specifically, in order to comprehensively consider the soil moisture and nutrient conditions, a unified fertilization period scheme is scientifically and reasonably formulated, the first fertilization interval time and the second fertilization interval time are compared, and the target fertilization interval time with a shorter interval time is determined.

The method comprises the specific operation of calculating a first fertilization interval time determined according to the current soil water content and a second fertilization interval time determined according to the soil water content. Comparing the two, assuming that the first interval time is 7 days and the second interval time is 10 days, taking the short time interval of the two, namely 7 days, as the target fertilization interval time.

Therefore, the soil moisture and nutrient consumption speed can be fully considered, and a time interval which can ensure the soil moisture content and the soil fertilizer content is selected for fertilization. If a longer second interval is directly employed, the soil moisture content may not be satisfactory for normal crop growth during the 10 days, resulting in water deficit. The shorter 7-day interval is adopted, so that the soil moisture and nutrients can be ensured to be supplemented in the period, the growth disorder of crops caused by insufficient moisture or fertilizer is prevented, the balance of the growth requirements is realized, and the healthy growth of the crops is promoted.

S103, after the target fertilization interval time, acquiring second soil fertilizer content and second soil water content and second weather data in a preset time period, and determining the target fertilization amount based on the second soil fertilizer content, the second soil water content, the growth stage of crops and the second weather data;

specifically, when the target fertilization interval time is reached, the second soil fertilizer content and water content and the second weather data in the preset time period are obtained again, so as to consider the soil nutrient and water change condition in the time interval, and the latest climate condition is combined to accurately calculate the fertilization amount. The specific method is that after the target fertilization interval is reached, soil is sampled again to detect fertilizer content and water content, and meanwhile weather forecast in a preset time period is queried to predict rainfall, air temperature, humidity and other information. And combining the detected second soil data, acquiring the current growth stage of the crops and the standard fertilization amount parameters of different preset growth stages, and determining the target fertilization amount through calculation. Therefore, the fertilizing amount can be dynamically adjusted according to the latest soil nutrition and moisture data, not only nutrition consumption, moisture evaporation, moisture required by crop transpiration and growth and the like in a time interval are considered, but also the condition that the future climate supplements the soil moisture is combined, so that the accurate supply of the fertilizer required by crops is realized, and the fertilizing is more intelligent and has strong pertinence.

On the basis of the above embodiment, as an optional implementation, the determining the target fertilizing amount based on the second soil fertilizer content, the second soil water content, the growth stage of the whole crop in the area to be fertilizing and the second weather data, further includes the following steps:

s401, determining a first water consumption according to second weather data and a growth stage of crops;

specifically, the first water consumption is obtained to evaluate the water consumption of different incubation periods under different climatic conditions in a preset period of time, and is used as an important basis for determining the irrigation quantity. The specific method comprises the following steps: inquiring a standard water consumption curve function of the crop in the current growth stage, establishing a climate influence coefficient function according to predicted second weather data including temperature, humidity, rainfall and the like, multiplying the standard water consumption curve by the climate influence coefficient function to obtain a first water consumption model, substituting specific growth stage and forecast meteorological data into the model, and calculating the first water consumption in a preset time period. Therefore, the influence of climate change on water consumption in different breeding stages can be fully considered, the total water consumption in a period in the future can be estimated, and the method is scientific and reasonable compared with a simple empirical value, and provides an accurate basis for determining the irrigation amount subsequently. Compared with traditional experience irrigation, the method can realize active replenishment of water demand of crops, so that excessive irrigation resource waste is prevented, and fertility disorder caused by insufficient irrigation is avoided.

S402, determining a target water supplementing amount according to the second soil water content, the growth stage of the whole crops in the area to be fertilized, second weather data and the first water consumption;

specifically, in order to reasonably determine the irrigation water consumption of crops, the second soil water content, the crop growth stage, the second weather data and the first water consumption are comprehensively considered to determine the target water supplementing amount.

The specific method comprises the following steps: detecting and acquiring real-time water content data of the second soil, combining a standard water consumption model of the current growth stage of crops and a first water consumption calculated according to predicted second weather data, comparing and analyzing the data, and evaluating the matching condition of the water content which can be provided by the soil in a preset time period and the total water consumption required by the crops, wherein if the water content which can be provided by the soil is insufficient to meet the water consumption requirement of the crops, the insufficient water consumption is taken as a target water supplementing quantity.

On the basis of the above embodiment, as an optional embodiment, S402, determining the target water supplementing amount according to the second soil water content, the growth stage of the whole crop in the area to be fertilized, the second weather data and the first water consumption, further includes the following steps:

s501, determining the precipitation time and weather data before precipitation according to the second weather data when the first water consumption is less than zero;

Specifically, after the predicted second weather data is obtained, a time point when the rainfall in the retrieved data is greater than 0 is the expected rainfall time. And then selecting a section closest to the rainfall time from the temperature, humidity and other data before the time point as weather data before rainfall. In this way, the specific occurrence time of rainfall and the climate condition of a period of time before the rainfall can be clearly known.

Determining relevant rainfall information can enable the device to reasonably plan an irrigation strategy, provide proper irrigation before rainfall comes, adjust irrigation quantity according to weather before rainfall, and avoid resource waste caused by excessive watering during rainfall. Compared with blind irrigation, the method can utilize natural rainfall resources to the maximum extent, reasonably allocate artificial irrigation amount, promote crop growth and improve water resource utilization efficiency.

S502, determining a second water consumption according to weather data before precipitation and the growth stage of the whole crops in the area to be fertilized;

specifically, after weather data such as temperature and humidity and the like of a period of time before rainfall is obtained, a weather influence coefficient is established according to a standard water consumption curve of the current growth stage of crops and the weather data. And multiplying the standard water consumption curve by the influence coefficient to calculate the second water consumption in the period from the current rainfall to the expected rainfall.

Therefore, the specific water consumption of crops under different climates can be estimated before rainfall comes, and the irrigation amount in the period of time can be reasonably planned. Compared with blind irrigation, the method can utilize a water consumption model before rainfall, only supplement water is provided according to the requirement, excessive irrigation is prevented, deficiency is prevented, rainfall resources are fully utilized, and the water utilization efficiency is improved.

S503, determining target water supplementing quantity according to the second water consumption, the second soil water content and the growth stage of the whole crops in the area to be fertilized;

specifically, a second water consumption from the current rainfall period to the expected rainfall period is calculated, real-time water content data of soil is detected and obtained, and standard water consumption of crops in the current growth stage is inquired. And comparing the three, and subtracting the water content available for the current soil from the larger value of the second water consumption and the standard water consumption, wherein the difference is the target water supplementing amount.

Thus, the total water consumption requirement of crops in the period of time can be evaluated, and the contribution of residual moisture of soil is considered, so that only the deficiency is supplemented, and excessive irrigation is avoided. Compared with fixed-quantity irrigation, the method can accurately provide the water replenishing quantity before rainfall, so that not only is the waste of water resources prevented, but also the water demand of crops is ensured, natural rainfall is utilized to the maximum extent, and the reasonable utilization of water is realized.

In a specific embodiment, if the area to be fertilized is an open area, determining the precipitation time and the weather data before precipitation according to the second weather data when the first water consumption is less than zero, determining the second water consumption according to the weather data before precipitation and the growth stage of the whole crop in the area to be fertilized, and determining the target water supplementing amount according to the second water consumption, the second soil water content and the growth stage of the whole crop in the area to be fertilized;

if the area to be fertilized is an area in the facility, the first water consumption is less than zero, the second water consumption in a preset time period is determined according to the second weather data and the growth stage of the whole crop in the area to be fertilized, and the target water supplementing amount is determined according to the second water consumption, the second soil water content and the growth stage of the whole crop in the area to be fertilized.

S504, when the second water consumption is greater than zero, determining the optimal water content of the soil according to the growth stage of the whole crops in the area to be fertilized;

specifically, the optimal soil moisture content range of the crop in the current growing stage is queried, and the maximum value in the range is set as the maximum threshold value of the soil moisture content. Thus, when the water content of the soil reaches the maximum threshold value, irrigation is not continued, so that the crop growth is prevented from being influenced by excessive humidity.

The maximum threshold value is set, so that the water can be supplemented for crops by reasonably utilizing the irrigation opportunity before rainfall comes, but the occurrence of deficiency and the occurrence of excess are avoided. Compared with fixed irrigation, the method can dynamically adjust the maximum soil moisture content according to different breeding stages and second water consumption, so that accurate management of the soil moisture is realized, the water demand of crops is ensured, and resource waste is prevented.

S505, determining the target water supplementing amount according to the second soil water content and the optimal water content of the soil.

Specifically, detecting and obtaining real-time water content data of the current soil, and determining a maximum threshold value of the water content of the soil according to the crop growth stage. Comparing the two, and taking the difference value of the two as a target water supplementing amount if the current soil water content is lower than a maximum threshold value; if the current water content has reached or exceeded the maximum threshold, the target water replenishment amount is set to 0.

Therefore, before the reserved rainfall comes, the insufficient water quantity can be supplemented preferentially according to the actual water condition of the soil, and excessive irrigation is avoided to exceed the upper threshold value. The method can reasonably utilize the irrigation opportunity before rainfall to provide sufficient moisture for crops, and simultaneously control the irrigation quantity according to the maximum threshold value, so that the accurate management of soil moisture is realized, the water demand of crops is ensured, and the resource waste is avoided.

S403, determining a target fertilizer supplementing amount according to the second soil fertilizer content and the growth stage of the whole crops in the region to be fertilized;

specifically, in order to reasonably determine the fertilizing amount of crops, the second soil fertilizing amount and the crop growth stage need to be considered to determine the target fertilizing amount.

The specific method comprises the following steps: and detecting and acquiring the real-time fertilizer content data of the second soil, and inquiring the standard fertilizer demand of the current crop growth stage. And comparing the standard fertilizer demand with the fertilizer content actually available for the soil, judging whether the residual nutrients of the soil can meet the nutritional requirements of the current fertility stage, and if the residual nutrients of the soil are insufficient, taking the insufficient amount as a target fertilizer supplementing amount.

Therefore, the method can evaluate and analyze the residual nutrition of the soil according to the fertilizer consumption condition of the actual growing stage of crops, only supplements the deficiency, and avoids resource waste and environmental hazard caused by excessive fertilization. Compared with the empirical fertilization, the method can accurately supplement nutrition required by crops, thereby improving the resource utilization efficiency and ensuring the growth requirement of the crops.

On the basis of the above embodiment, as an optional embodiment, S403, determining the target fertilizer replenishment amount according to the second soil fertilizer content and the growth stage of the whole crop in the area to be fertilized, includes:

S601, determining the optimal fertilizer content of soil according to the growth stage of the whole crops in the area to be fertilized;

specifically, the fertilizer demand of the crops in the current growing stage is inquired, and the ideal fertilizer content of the soil which just meets the growing demand is determined by referring to factors such as the soil type, the crop variety and the like. On the basis, a floating zone is set to obtain the optimal fertilizer content of the soil.

The dynamic threshold interval of the optimal fertilizer content of the soil is set, so that soil fertility targets can be flexibly adjusted according to different growing stages, and accurate management of soil nutrition states is realized. When the soil fertilizer content is detected to be lower than the minimum threshold value, fertilizer is needed to be supplemented; conversely, if the amount is higher than the maximum threshold value, the amount of fertilizer applied can be appropriately reduced. Compared with a static threshold value, the method can actively regulate and control soil nutrition according to the real-time demand of crops, so that the growth is prevented from being influenced by fertilizer deficiency, and resource waste caused by excessive fertilization can be avoided.

S602, determining a target fertilizer supplementing amount according to the optimal fertilizer containing amount of the soil and the fertilizer containing amount of the second soil.

Specifically, a floating target interval of the soil fertilizer amount is set according to the crop growing stage, and the current real-time fertilizer content of the soil is detected and obtained. Comparing the two, and if the current fertilizer content is lower than the lower limit of the threshold interval, calculating the difference value of the two as a target fertilizer supplementing amount; if the current fertilizer content is higher than the upper limit of the interval, the target fertilizer supplementing amount is set to be 0.

Therefore, the residual nutrition of the soil can be dynamically evaluated according to the real-time fertilizer consumption condition of crops, and only the deficiency is supplemented, so that the resource waste caused by excessive fertilization is avoided. Compared with static threshold management, the method can realize active control of the soil nutrition state, effectively balance the crop fertilizer demand and the soil nutrient supply, ensure the fertility demand and improve the resource utilization efficiency.

S404, determining the target fertilization amount based on the target fertilization amount and the target water replenishment amount.

Specifically, in order to uniformly schedule the time of fertilization and irrigation, the target fertilization amount needs to be determined based on the target fertilization amount and the target water replenishment amount.

The specific method is that the calculated target fertilizer supplementing amount is compared with the target water supplementing amount, and the larger value is selected as the target fertilizer supplementing amount. Thus, the soil moisture can be supplemented while fertilization is ensured. If fertilizer is applied only with the fertilizer supplementing amount as the target amount, the water requirement of crops may not be met; and if the fertilizer is applied only with the water supplementing amount as the target amount, the waste of the nutrient surplus is possibly caused. Therefore, the large value in the two can be adopted to realize the supplement of soil fertility in a unified fertilization time, and sufficient irrigation water source is provided, so that the water and fertilizer requirements of crops are met, the crops can be supplied with comprehensive and balanced nutrition, and the healthy growth of the crops is promoted.

S104, determining the quality of the fertilizer in the water fertilizer and the quality of water based on the target fertilizing amount and the area of the area to be fertilized.

Specifically, the required water and fertilizer quality is calculated based on the target fertilizing amount and the area of the area to be fertilized, so as to prepare a proper amount of water and fertilizer according to the fertilizing scheme. The specific method comprises the steps of measuring or consulting the area of the field to be fertilized after the target fertilization amount is determined, and calculating the weight of water and various fertilizers to be prepared according to the conversion relation between the area and the fertilization amount. The device outputs the calculation result to guide the field personnel to prepare the water source and the fertilizer according to the recommended amount. Therefore, excessive or insufficient water and fertilizer prepared according to experience judgment can be prevented, accurate material control is realized, resource waste is avoided, fertilizer application requirements of crops are met, and accurate fertilizer application is realized. Different from the traditional empirical preparation of the water and fertilizer, the method can actively calculate the required water and fertilizer consumption, accurately grasp the material demand, and is beneficial to improving the resource utilization efficiency and reducing the cost expenditure.
