[0031] S1, obtain the current time point data, and determine that when the time point data reaches the pre-set fertilization time, obtain the climate data within the pre-set time period after the current time point and the soil data of the controlled area.

[0032] In the present invention, a fertilization management device is provided. The fertilization management device may include a fertilization management system and a user terminal.

[0033] In an embodiment of the present invention, the fertilization management system is provided with a time collector, a comparator, and stores a fertilization plan table, which is obtained through theoretical calculation and specifically includes fertilization time, fertilization amount, and the type of fertilizer corresponding to the fertilization time.

[0034] S2. When it is determined that the weather is suitable according to the climate data, control fertilization according to the soil data.

[0035] In an embodiment of the present invention, it is determined whether to fertilize by calculating the precipitation within a preset time period. When the precipitation is too large, even if fertilization is carried out, it will cause fertilizer loss and losses. Therefore, suitable weather is required for fertilization.

[0036] Further, the step of obtaining the current time point data and determining that when the time point data reaches the preset fertilization time, obtaining the climate data within a preset time period after the current time point and the soil data of the controlled area specifically includes the following steps:

[0037] S11. Obtain the current time point data;

[0038] In an embodiment of the present invention, the current real-time Beijing time is recorded in real time through a timer. The current time point data mainly consists of year, month, and day, and the current real-time Beijing time is obtained in real time through a time collector.

[0039] S12. When it is determined that the current time point data reaches the fertilization time, obtain the climate data from the current time point to the fertilization end time point and the soil data of the controlled area.

[0040] In an embodiment of the present invention, a data search algorithm is used to compare the current time point data with the data in the fertilization plan table in terms of time point values. According to the time point value comparison result, when the monitoring result data reaches the fertilization time, the climate data from the current time point to the fertilization end time point and the soil data of the controlled area can be obtained.

[0041] In an embodiment of the present invention, for example, when applying base fertilizer, it is suitable from the first ten days of September to the first ten days of October in a year. At this time, the fertilization time can be set from the first ten days of September to the first ten days of October, and the fertilization end time data can be October 16th or 10 days later; the precipitation for each day from the current time point to the fertilization end time point is obtained through the weather search algorithm.

[0042] In an embodiment of the present invention, the humidity and remaining fertilizer amount of the soil are obtained through sensors, such as the nitrogen, phosphorus, and potassium contents in the soil. The amount of actual fertilization required is calculated based on the remaining fertilizer amount and the planned fertilization amount in the fertilization plan.

[0043] Further, when it is determined that the weather is suitable according to the climate data, controlling fertilization according to the soil data specifically includes the following steps:

[0044] S21, calculate the average precipitation within three adjacent days from the current time point to the fertilization end time point;

[0045] In an embodiment of the present invention, the average precipitation of three adjacent days is calculated based on the precipitation of each day. For example, the precipitation on September 15th is 500 ml, the precipitation on September 16th is 100 ml, the precipitation on September 17th is 0 mL, the precipitation on September 18th is 200 ml, the precipitation on September 19th is 100 ml, etc. The average precipitation of three adjacent days is calculated respectively as follows: the average precipitation from September 15th to September 17th is 200 ml, the average precipitation from September 16th to September 18th is 100 mL, the average precipitation from September 17th to September 19th is 100 ml, etc.

[0046] S22, obtain the time with the minimum average precipitation within three adjacent days from the current time point to the fertilization end time point;

[0047] In an embodiment of the present invention, if it is necessary to ensure the least rainfall during fertilization, it can be calculated for four days, five days, six days, etc.

[0048] S23, obtain the soil humidity;

[0049] In the present invention, it specifically includes the following steps:

[0050] S231, divide the controlled area into multiple areas;

[0051] S232, obtain the actual humidity value of each area and record it as Ti, i = 1.....n;

[0052] S233, calculate the average soil humidity value T of the controlled area,

[0053] S24. Determine that when the soil humidity is less than the preset maximum humidity and greater than the preset minimum humidity, obtain the soil fertilizer information, calculate the fertilization amount based on the soil fertilizer information, and send the fertilization information.

[0054] When the soil humidity is less than the preset maximum humidity and greater than the preset minimum humidity, the process proceeds to step S25. When the soil humidity is greater than the preset maximum humidity or less than the preset minimum humidity, the process proceeds to step S21.

[0055] In an embodiment of the present invention, a preset maximum humidity and a preset minimum humidity can be set through the system. This humidity can prevent the fertilizer from being diluted and wasted due to excessive humidity after fertilization, and prevent the soil from being too dry to absorb the fertilizer well, resulting in insufficient soil fertilizer, when the humidity is too low.

[0056] In an embodiment of the present invention, the fertilizer information in the soil is detected by multiple sensors in the soil testing instrument. For example, obtain the nitrogen fertilizer content information in the soil. The actual nitrogen fertilizer content is 20 kg per hectare, and the actual content is lower than the preset content (40 kg per hectare). Therefore, 20 kg of fertilizer per hectare needs to be applied.

[0057] The fertilization information includes the fertilization time, the fertilization amount, and the type of fertilizer.

Taking 50 mu as an experimental unit, 3 plots were randomly selected and marked as Experimental Plot 1, Experimental Plot 2, and Experimental Plot 3 respectively; the operations were carried out according to Example 1, Example 2, and Example 6 respectively; for Comparative Plot 1, the operation was carried out according to the conventional method, which was consistent with the background technology. Through actual measurement, the plums in Experimental Plot 1, Experimental Plot 2, and Experimental Plot 3 started to bear fruit in the third year and reached the peak production in the fifth year. In Experimental Plot 1 and Experimental Plot 2, the average annual harvest per mu was 500 - 600 kg, the average weight of each plum was 50 - 80 g, and the fruit color and taste were good. In Experimental Plot 3, the average annual harvest per mu was 600 - 750 kg, the average weight of each plum was 60 - 100 g, and the fruit color and taste were good; the plums in Comparative Plot 1 also reached the peak production in the fifth year, but the average annual harvest per mu was 200 - 300 kg, the size was smaller, about 30 - 50 g, and there was a situation of one year more and one year less thereafter, and the yield was unstable.
