[0002] With the continuous development of agricultural science and technology, intelligent agriculture is playing an increasingly important role in improving crop production efficiency, reducing resource waste and environmental pollution. In the field of rice production, rice transplanters, as a key agricultural machinery and equipment, undertake the important task of planting rice. By installing various sensors on the rice transplanters, such as soil moisture sensors, temperature sensors, nutrient content sensors, etc., the status of soil and crops can be monitored in real time, providing accurate data support for fertilization, irrigation and crop management.

[0003] Under the current technical background, limited by the existing rice planting model and equipment level, the existing fertilization equipment generally has problems such as accumulation and blockage, poor fertilization uniformity, difficulty in adjusting the fertilizer amount, and low intelligence level. Therefore, how to realize intelligent control of fertilizer application amount based on soil fertility is a technical problem.

[0004] To this end, the present invention proposes an intelligent precision fertilization method, system and medium for a rice transplanter. Summary of the invention

[0010] Step S100, demarcating the operating range of the rice transplanter to obtain a rice seedling raising area and a non-rice seedling raising area;

[0011] Step S200, obtaining regional status data of the seedling raising area;

[0012] Step S300, comprehensively analyzing the field conditions of the rice fields corresponding to the rice seedling raising area in combination with the regional status data, and if the field conditions are analyzed to be a rice seedling raising area that is not suitable for raising rice seedlings, dispatching staff to the designated area to improve the mud layer and water level of the rice fields;

[0013] Step S400, if the suitable level of the seedling raising area is obtained through analysis, the fertilization scheme of each seedling raising area is configured in combination with the suitable level of the seedling raising to obtain the actual configured fertilizer amount of the seedling raising area;

[0014] Step S500, causing the fertilizing unit in the rice transplanter to load fertilizer according to the actual fertilizer amount configured in the rice seedling raising area.

[0015] Furthermore, the area demarcation in step S100 includes the following sub-steps:

[0016] When the rice field is rectangular in shape, the rice seedling raising area and non-rice seedling raising area are demarcated according to the dividing line between the water area and the land;

[0017] If the shape of the rice field is irregular, the shape of the rice field is corrected to obtain one or more rectangles whose areas are smaller than the area of ​​the rice field. The area occupied by the rectangles is marked as the seedling raising area, and the remaining irregular area in the rice field is marked as the non-seedling raising area.

[0018] Furthermore, the regional status data include the regional area of ​​the seedling raising area, the planting area, the mud layer height, the water layer height, the mud water oxygen content, the mud water nitrogen content, the mud water phosphorus content, the mud water potassium content and the mud water pH value.

[0019] Furthermore, the comprehensive analysis process of step S300 is specifically as follows:

[0020] Step S301, obtaining the height of the mud layer in the rice seedling raising area, and comparing the height of the mud layer with the critical height of the rice seedling raising mud layer;

[0021] Step S302, if the mud layer height in the seedling raising area is less than the critical height of the mud layer in the seedling raising area, it is determined that the field state in the seedling raising area is not suitable for seedling raising;

[0022] Step S303, if the mud layer height in the seedling raising area is greater than or equal to the critical height of the mud layer in the seedling raising area, then obtaining the water layer height in the seedling raising area, and comparing the water layer height with the seedling raising water level interval;

[0023] Step S304: if the water layer height in the seedling raising area does not belong to the seedling raising water level interval, it is determined that the field state in the seedling raising area is not suitable for seedling raising.

[0024] Furthermore, the comprehensive analysis process of step S300 further includes:

[0025] Step S305, if the water layer height of the seedling raising area belongs to the seedling raising water level interval, then obtain the mud water oxygen content NO, mud water nitrogen content NN, mud water phosphorus content NP, mud water potassium content NK and mud water pH value PH in the seedling raising area, and calculate the fertility deviation value PC of the seedling raising area according to the formula, which is as follows:

[0026] PC=(|NO-BO|+|PH-BPH|)×a1+(|NN-BN|+|NP-BP|+|NK-BK|)×a2;

[0027] Among them, BO is the optimum oxygen content for seedlings, BN is the optimum nitrogen content for seedlings, BP is the optimum phosphorus content for seedlings, BK is the optimum potassium content for seedlings, BPH is the optimum pH value for seedlings, a1 and a2 are fixed proportional coefficients, the values ​​of a1 and a2 are both greater than zero, a1 is the seedling environment coefficient, and a2 is the seedling fertility coefficient;

[0028] Step S306, comparing the fertility deviation value of the seedling raising area with the fertility deviation threshold, and determining whether the seedling raising suitability level of the seedling raising area is the third seedling raising suitability level, the second seedling raising suitability level, or the first seedling raising suitability level.

[0029] Further, the suitability of the first seedling raising suitability level is lower than the suitability of the second seedling raising suitability level;

[0030] The suitability of the second seedling raising suitability level is lower than the suitability of the third seedling raising suitability level.

[0031] Furthermore, the configuration process of the fertilization scheme in step S400 is specifically as follows:

[0032] Step S401, obtaining the area QS and planting area ZS of the seedling raising area, and calculating the fertilizer compensation ratio FC of the seedling raising area according to the formula FC=QS / ZS. The specific formula is as follows:

[0033] Step S402, then obtaining the suitable level of the seedling raising area, and selecting the corresponding fertilizer correction coefficient XZ according to the suitable level of the seedling raising area;

[0034] Step S403, calculating the actual fertilizer amount SF in the seedling raising area according to the formula, the specific formula is as follows:

[0035] ;

[0036] in," ” is the rounding down symbol, DS is the unit planting area of ​​rice seedlings, and BL is the standard fertilizer amount per unit planting area.

[0037] Furthermore, the corresponding relationship between the suitable level of seedling cultivation and the fertilizer correction coefficient is as follows:

[0038] If the suitability level of the seedling raising area is the first suitability level, the value of the corresponding fertilizer correction coefficient is s3;

[0039] If the suitability level of the seedling raising area is the second suitability level, the value of the corresponding fertilizer correction coefficient is s2;

[0040] If the suitability level for raising seedlings in the raising seedling area is the third suitability level for raising seedlings, the value of the corresponding fertilizer correction coefficient is s1; wherein, 0<s1<s2<s3.

[0041] In the second aspect, an intelligent precision fertilization system for a rice transplanter includes a server, a regional planning module, a data acquisition module, a field analysis module, an execution terminal, a program correction module, and a material preparation terminal;

[0042] The regional planning module is used to demarcate the operating range of the rice transplanter to obtain the seedling raising area and the non-seedling raising area. The server synchronizes the seedling raising area to the data acquisition module;

[0043] A data acquisition module is used to acquire regional status data of the seedling raising area and send the regional status data to the server, and the server sends the field status data of the seedling raising area to the field analysis module;

[0044] The field analysis module is used to conduct a comprehensive analysis of the field conditions of the rice fields corresponding to the seedling raising area. If the field conditions are found to be unsuitable for raising rice seedlings, the information will be synchronized to the execution terminal. The execution terminal will immediately dispatch staff to the designated area to improve the mud layer and water level of the rice fields. If the analysis shows that the rice seedling raising area is suitable for raising rice seedlings, the information will be sent to the solution correction module through the server.

[0045] The scheme correction module is used to configure the fertilization scheme of each seedling raising area, obtain the actual amount of fertilizer configured in the seedling raising area, and the server sends the actual amount of fertilizer configured in the seedling raising area to the material preparation terminal;

[0046] The material preparation terminal is used to enable the fertilization unit in the rice transplanter to load fertilizer according to the actual fertilizer amount configured in the rice seedling raising area.

[0047] In a third aspect, a computer-readable storage medium stores a computer program, which implements an intelligent precision fertilization method when executed by a processor.

[0048] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0049] The present invention first demarcates the operating range of the rice transplanter to obtain the seedling raising area and the non-seedling raising area, and then comprehensively analyzes the field conditions of the rice fields corresponding to the seedling raising area in combination with the regional status data. If the field conditions are analyzed to be the seedling raising area that is not suitable for seedling raising, repairs are carried out. If the analysis obtains the seedling raising suitability level of the seedling raising area, fertilization plans for each seedling raising area are configured to obtain the actual configured fertilizer amount of the seedling raising area. Finally, according to the actual configured fertilizer amount of the seedling raising area, the fertilization unit in the rice transplanter can perform fertilizer loading operations. The present invention combines multiple factors to realize intelligent fertilization and precise fertilization in the planting area. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Example 1: Please refer to Figure 1-Figure 3 As shown, the technical solution provided by the present invention is: an intelligent and precise fertilization method for a rice transplanter. In this embodiment, the rice transplanter is used for transplanting operations and subsequent fertilization operations in various rice fields. In the actual working process, the rice transplanter is equipped with a transplanting unit and a fertilization unit. After the rice seedlings are sown by the transplanting unit, the fertilization unit performs the initial fertilization operation according to the sowing situation of the transplanting unit. In the process of the rice seedlings growing to maturity, the rice transplanter performs subsequent fertilization operations through the fertilization unit.

[0058] In this embodiment, the intelligent precision fertilization method is as follows:

[0059] Step S100, demarcating the operating range of the rice transplanter to obtain a rice seedling raising area and a non-rice seedling raising area;

[0060] In this embodiment, the area demarcation in step S100 includes the following sub-steps:

[0061] like Figure 2As shown, when the shape of the rice field is a rectangle, the seedling raising area and the non-seedling raising area are delineated according to the dividing line between the water area and the land; in the actual work process, due to the influence of objective factors such as topography and terrain, the actual shape of the rice field does not strictly conform to the shape characteristics of the rectangle, that is, when the shape of the rice field is an irregular shape, the shape of the irregular-shaped rice field is corrected; after the correction, one or more rectangles with an area smaller than the area of ​​the rice field are obtained, and then the area occupied by the rectangle is marked as the seedling raising area, and the remaining irregular area in the rice field is marked as the non-seedling raising area.

[0062] Step S200, obtaining regional status data of the seedling raising area;

[0063] It should be specifically noted that the regional status data include the regional area of ​​the seedling raising area, the planting area, the height of the mud layer, the height of the water layer, the oxygen content of the mud water, the nitrogen content of the mud water, the phosphorus content of the mud water, the potassium content of the mud water and the pH value of the mud water;

[0064] like Figure 3 As shown in the figure, the regional area is the total area of ​​the rice field corresponding to the seedling raising area, and the planting area is the actual area of ​​the seedling raising area. Specifically, the regional area includes the part of the area that is divided into the non-seedling raising area during the shape correction process. It is understandable that due to the water circulation of the rice planting environment, some fertilizers in the seedling raising area will inevitably spread to the non-seedling raising area during the shape correction process. Figure 4 As shown, the mud layer height is the height of the mud-water mixed part in the seedling raising area, and the water layer height is the height difference from the water surface to the mud-water mixed part in the seedling raising area. In this embodiment, the seedling raising area is provided with an oxygen sensor, a nutrient content sensor and an acid-base sensor, and the sensing part of the sensor is placed in the mud-water mixed part. The oxygen content of the mud and water in the seedling raising area is obtained by the oxygen sensor, the nitrogen content, phosphorus content and potassium content of the mud and water in the seedling raising area are obtained by the nutrient content sensor, and the pH value of the mud and water in the seedling raising area is obtained by the acid-base sensor.

[0065] Step S300, comprehensively analyzing the field conditions of the rice fields corresponding to the rice seedling raising area in combination with the regional status data, and if the field conditions are analyzed to be a rice seedling raising area that is not suitable for raising rice seedlings, dispatching staff to the designated area to improve the mud layer and water level of the rice fields;

[0066] The comprehensive analysis of step S300 is as follows:

[0067] Step S301, obtaining the height of the mud layer in the rice seedling raising area, and comparing the height of the mud layer with the critical height of the rice seedling raising mud layer;

[0068] Step S302, if the mud layer height in the seedling raising area is less than the critical height of the mud layer in the seedling raising area, it is determined that the field state in the seedling raising area is not suitable for seedling raising;

[0069] Step S303, if the mud layer height in the seedling raising area is greater than or equal to the critical height of the mud layer in the seedling raising area, then obtaining the water layer height in the seedling raising area, and comparing the water layer height with the seedling raising water level interval;

[0070] Step S304, if the water layer height in the seedling raising area does not belong to the seedling raising water level interval, it is determined that the field state in the seedling raising area is not suitable for seedling raising;

[0071] Step S305, if the water layer height of the seedling raising area belongs to the seedling raising water level interval, then obtain the mud water oxygen content NO, mud water nitrogen content NN, mud water phosphorus content NP, mud water potassium content NK and mud water pH value PH in the seedling raising area, and calculate the fertility deviation value PC of the seedling raising area according to the formula, which is as follows:

[0072] PC=(|NO-BO|+|PH-BPH|)×a1+(|NN-BN|+|NP-BP|+|NK-BK|)×a2;

[0073] Among them, BO is the optimum oxygen content for seedling cultivation, BN is the optimum nitrogen content for seedling cultivation, BP is the optimum phosphorus content for seedling cultivation, BK is the optimum potassium content for seedling cultivation, BPH is the optimum pH value for seedling cultivation, a1 and a2 are proportional coefficients with fixed values, and the values ​​of a1 and a2 are both greater than zero, a1 is the seedling cultivation environment coefficient, and a2 is the seedling cultivation fertility coefficient. It can be understood that the oxygen content and pH level of the rice field will affect the absorption effect of the fertilizer by the seedlings and even affect the survival and growth of the seedlings, such as root rot and root burn. The nitrogen content, phosphorus content and potassium content will affect the growth environment of the seedlings. For example, a rice field with too high phosphorus content will cause phosphorus accumulation, thereby affecting the biodiversity of the seedling cultivation area, which is not conducive to building a suitable seedling cultivation environment;

[0074] Step S306, comparing the fertility deviation value of the seedling raising area with the fertility deviation threshold;

[0075] Step S307, if the fertility deviation value is less than or equal to the first fertility deviation threshold, determining that the seedling raising suitability level of the seedling raising area is the third seedling raising suitability level;

[0076] Step S308, if the fertility deviation value is greater than the first fertility deviation threshold and less than or equal to the second fertility deviation threshold, determining that the seedling raising suitability level of the seedling raising area is the second seedling raising suitability level;

[0077] Step S309, if the fertility deviation value is greater than the second fertility deviation threshold, determining that the seedling raising suitability level of the seedling raising area is the first seedling raising suitability level;

[0078] Among them, the first fertility deviation threshold and the second fertility deviation threshold are both greater than zero, the first fertility deviation threshold is less than the second fertility deviation threshold, the suitability of the first seedling raising suitability level is lower than the suitability of the second seedling raising suitability level, and the suitability of the second seedling raising suitability level is lower than the suitability of the third seedling raising suitability level;

[0079] In actual working process, intelligent water valves can be configured in rice fields, and the valve opening can be adjusted according to the valve adjustment signal generated by the execution terminal to achieve water level control.

[0080] Step S400, if the suitable level of the seedling raising area is obtained through analysis, the fertilization scheme of each seedling raising area is configured in combination with the suitable level of the seedling raising to obtain the actual configured fertilizer amount of the seedling raising area;

[0081] In this embodiment, the configuration process of the fertilization scheme in step S400 is specifically as follows:

[0082] Step S401, obtaining the area QS and planting area ZS of the seedling raising area, and calculating the fertilizer compensation ratio FC of the seedling raising area according to the formula, the specific formula is as follows:

[0083] FC=QS / ZS;

[0084] It can be understood that the value of the area in the seedling raising area is always greater than or equal to the planting area, so the value of the fertilizer compensation ratio is always greater than 1;

[0085] Step S402, then obtain the suitable level of the seedling raising area, select the corresponding fertilizer correction coefficient according to the suitable level of the seedling raising, and the corresponding relationship between the fertilizer correction coefficient XZ and the suitable level of the seedling raising is as follows:

[0086] If the suitable level of the seedling raising area is the first suitable level, the value of the corresponding fertilizer correction coefficient is equal to s3; if the suitable level of the seedling raising area is the second suitable level, the value of the corresponding fertilizer correction coefficient is equal to s2; if the suitable level of the seedling raising area is the third suitable level, the value of the corresponding fertilizer correction coefficient is equal to s1; wherein, 0<s1<s2<s3;

[0087] Step S403, calculating the actual fertilizer amount SF in the seedling raising area according to the formula, the specific formula is as follows:

[0088] ;

[0089] in," " is the rounding down symbol, DS is the unit planting area of ​​rice seedlings, BL is the standard configuration fertilizer amount per unit planting area. It can be understood that when the fertility of the seedling raising area is insufficient, the calculation symbol before the fertilizer amount correction coefficient is "+", and when the fertility of the seedling raising area is excessive, the calculation symbol before the fertilizer amount correction coefficient is "-".

[0090] Step S500, causing the fertilization unit in the rice transplanter to perform a fertilizer loading operation according to the actual fertilizer amount configured in the rice seedling raising area;

[0091] In the actual working process, after the rice transplanter completes the transplanting operation, the fertilization unit performs fixed-point and quantitative fertilization operations according to the position of the seedlings to ensure that the fertilizer nutrients in the seedling raising area are evenly distributed.

[0092] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.

[0093] Example 2: Figure 4 As shown, based on another concept of the same invention, an intelligent precision fertilization system for a rice transplanter is proposed, the system includes a server, a regional planning module, a data acquisition module, a field analysis module, an execution terminal, a program correction module and a material preparation terminal;

[0094] The area planning module is used to demarcate the operating range of the rice transplanter, and send the seedling raising area and the non-seedling raising area to the server, and the server synchronizes the seedling raising area to the data acquisition module.

[0095] The data acquisition module is used to obtain the regional status data of the seedling raising area and send the regional status data to the server, and the server sends the field status data of the seedling raising area to the field analysis module, wherein the regional status data includes the regional area of ​​the seedling raising area, the planting area, the mud layer height, the water layer height, the mud water oxygen content, the mud water nitrogen content, the mud water phosphorus content, the mud water potassium content and the mud water pH value.

[0096] The field analysis module is used to conduct a comprehensive analysis of the field conditions of the rice fields corresponding to the rice seedling raising area. The specific analysis process is as follows:

[0097] The height of the mud layer in the seedling raising area is obtained, and the mud layer height is compared with the critical height of the mud layer for seedling raising; if the height of the mud layer in the seedling raising area is less than the critical height of the mud layer for seedling raising, the field state in the seedling raising area is determined to be unsuitable for seedling raising; if the height of the mud layer in the seedling raising area is greater than or equal to the critical height of the mud layer for seedling raising, the height of the water layer in the seedling raising area is obtained, and the water layer height is compared with the water level interval for seedling raising; if the water layer height in the seedling raising area does not belong to the water level interval for seedling raising, the field state in the seedling raising area is determined to be unsuitable for seedling raising; if If the height of the water layer belongs to the seedling raising water level range, then the mud water oxygen content NO, mud water nitrogen content NN, mud water phosphorus content NP, mud water potassium content NK and mud water pH value PH in the seedling raising area are obtained, and the fertility deviation value PC of the seedling raising area is calculated according to the formula PC=(|NO-BO|+|PH-BPH|)×a1+(|NN-BN|+|NP-BP|+|NK-BK|)×a2, where BO is the optimum oxygen content for seedling raising, BN is the optimum nitrogen content for seedling raising, and BP is the optimum phosphorus content for seedling raising. amount, BK is the optimum potassium content for seedling raising, BPH is the optimum pH value for seedling raising, a1 and a2 are proportional coefficients of fixed values, the values ​​of a1 and a2 are both greater than zero, a1 is the seedling raising environment coefficient, and a2 is the seedling raising fertility coefficient; the fertility deviation value of the seedling raising area is compared with the fertility deviation threshold; if the fertility deviation value is less than or equal to the first fertility deviation threshold, the seedling raising suitability level of the seedling raising area is determined to be the third seedling raising suitability level; if the fertility deviation value is greater than the first fertility deviation threshold and less than or equal to the second fertility deviation threshold, the seedling raising suitability level of the seedling raising area is determined to be the second seedling raising suitability level; if the fertility deviation value is greater than the second fertility deviation threshold, the seedling raising suitability level of the seedling raising area is determined to be the first seedling raising suitability level; wherein, the first fertility deviation threshold and the second fertility deviation threshold are both greater than zero, the first fertility deviation threshold is less than the second fertility deviation threshold, the suitability of the first seedling raising suitability level is lower than the suitability of the second seedling raising suitability level, and the suitability of the second seedling raising suitability level is lower than the suitability of the third seedling raising suitability level;

[0098] The field analysis module synchronizes the seedling raising areas whose field conditions are unsuitable for seedling raising to the execution terminal, and the execution terminal immediately dispatches staff to the designated area to improve the mud layer and water level of the rice field. At the same time, the field analysis module also sends the seedling raising suitability level of the seedling raising area to the server, and the server sends the seedling raising suitability level of the seedling raising area to the scheme correction module.

[0099] The scheme modification module is used to configure the fertilization scheme for each seedling raising area. The configuration process of the fertilization scheme is as follows:

[0100] Obtain the regional area QS and planting area ZS of the seedling raising area, and calculate the fertilizer compensation ratio FC of the seedling raising area according to the formula FC=QS / ZS; then obtain the suitable level of seedling raising in the seedling raising area, and select the corresponding fertilizer correction coefficient XZ according to the suitable level of seedling raising; according to the formula Calculate the actual fertilizer amount SF in the seedling raising area, where " ” is the rounding down symbol, DS is the unit planting area of ​​rice seedlings, BL is the standard fertilizer amount per unit planting area;

[0101] The scheme correction module sends the actual amount of fertilizer configured in the seedling raising area to the server, and the server sends the actual amount of fertilizer configured in the seedling raising area to the material preparation terminal; the material preparation terminal is used to enable the fertilization unit in the rice transplanter to load fertilizer according to the actual amount of fertilizer configured in the seedling raising area.
