[0033] Figure 1 The flowchart of a method for generating an irrigation plan according to an embodiment of the present application is schematically shown. Figure 1 As shown, an embodiment of the present application provides a method for generating an irrigation plan, which may include the following steps.

[0034] Step 101: Obtain the first standard water level required by the crop in the current growth stage.

[0035] Step 102: Construct a first function based on the area of ​​the planting area where the crop is planted and the historical rainfall data of the planting area.

[0036] The processor may obtain a first standard water level required by the crop at the current growth stage, and the crop may be rice, wheat, etc. Assuming the crop is rice, the current growth stage may be any one of the greening period, tillering period, booting period, heading period, and filling period. The processor may obtain the area of ​​the planting area where the crop is planted. After obtaining the area of ​​the planting area where the crop is planted, the processor may construct a first function based on the area of ​​the planting area where the crop is planted and the historical rainfall data of the planting area.

[0037] In an embodiment of the present application, the historical rainfall data includes multiple historical water levels before and after rainfalls, historical water levels and historical rainfalls of the planting area. Constructing a first function based on the area of ​​the planting area where crops are planted and the historical rainfall data of the planting area includes: determining each historical unit water level rise based on each historical water level before and after rainfalls, historical water level and area; fitting all historical unit water levels and all historical rainfalls to obtain the first function.

[0038] The historical rainfall data includes multiple historical water levels before rainfall, water levels after rainfall, and historical rainfall in the planting area. The processor can construct a first function based on the area of ​​the planting area where the crop is planted and the historical rainfall data of the planting area. Specifically, the processor can determine each historical unit rise water level based on each historical water level before rainfall, water level after rainfall, and area. And fit all historical unit rise water levels and all historical rainfall to obtain the first function.

[0039] In an embodiment of the present application, determining the water level rise for each historical unit based on the water level before each historical rainfall, the water level after each historical rainfall, and the area includes: determining the difference between the water level after each historical rainfall and the water level before each historical rainfall; and determining the ratio of each difference to the area as the water level rise for each historical unit.

[0040] The processor can determine each historical unit water level rise according to each historical water level before rainfall, the water level after rainfall, and the area. Specifically, the processor can determine the difference between each historical water level after rainfall and the water level before rainfall. And the ratio of each difference to the area is determined as each historical unit water level rise.

[0041] For example, the planting area is field i, and the area is Si. For a certain rainfall in history, the historical water level before rainfall of field i is Hiq, the historical water level after rainfall is Hih, and the historical rainfall is Ris. The processor can determine the difference (Hih-Hiq) between the historical water level Hiq before rainfall and the historical water level Hih after rainfall. And the ratio (Hih-Hiq) / Si of the difference (Hih-Hiq) and the area Si is determined as the historical unit rising water level His of the rainfall. After obtaining the historical unit rising water level His and the historical rainfall Ris of at least two historical rainfalls, the processor can fit all the historical unit rising water levels His and the historical rainfall Ris to obtain a first function, which characterizes the correlation between the historical unit rising water level and the historical rainfall. The first function is His=kRis+b, where k and b are both constants.

[0042] Step 103: Obtain the predicted daily maximum temperature within a first preset future time period.

[0043] Step 104: When the predicted daily maximum temperature reaches a preset condition, the first standard water level is adjusted according to the predicted daily maximum temperature.

[0044] Step 105: Get the current water level of the planting area.

[0045] Step 106: When the current water level is less than the adjusted first standard water level, obtain predicted rainfall data within a second preset future time period, wherein the second preset future time period is less than or equal to the first preset future time period.

[0046] Step 107: Determine the unit rise water level within a second preset future time period according to the first function and the predicted rainfall data.

[0047] Step 108: Generate an irrigation plan for the planting area according to the unit rising water level, the area, the current water level and the adjusted first standard water level.

After obtaining the predicted daily maximum temperature within the first preset future duration, the processor may determine whether the predicted daily maximum temperature within the first preset future duration meets the preset condition, the first preset future duration may be determined based on the actual situation, and the preset condition may be determined based on the actual situation, for example, the preset condition may be that the daily maximum temperature is higher than 38°C for more than three consecutive days in the future. In the case where the predicted daily maximum temperature meets the preset condition, the processor may adjust the first standard water level according to the predicted daily maximum temperature to obtain the adjusted first standard water level. The processor may obtain the current water level of the planting area. After obtaining the current water level of the planting area, the processor may determine whether the current water level of the planting area is less than the adjusted first standard water level. In the case where the current water level is less than the adjusted first standard water level, the processor may obtain the predicted rainfall data within the second preset future duration, wherein the second preset future duration is less than or equal to the first preset future duration, and the second preset future duration is determined based on the actual situation. After obtaining the predicted rainfall data, the processor may determine the unit rise water level within the second preset future duration according to the first function and the predicted rainfall data.

[0058] After obtaining the irrigation plan, the processor may send the irrigation plan to the user to inform the user to irrigate the planting area according to the irrigation plan.

[0059] In the embodiment of the present application, the crop is rice, and the current growth stage of the rice is the tillering stage. Based on Table 1, the processor can determine the first standard water level (H ) required for the rice in the tillering stage. b1 ) is 3cm.

[0061] Reproductive Stage Green period Tillering period Booting stage Heading and flowering period Grouting period <![CDATA[H b1 ]]> 2cm 3cm 3cm 5cm 2cm

[0062] The processor can obtain the area Si of the planting area where rice is planted. For a certain rainfall in history, the historical water level before rainfall in the planting area is Hiq, the historical water level after rainfall is Hih, and the historical rainfall is Ris. The processor can determine the difference (Hih-Hiq) between the historical water level Hiq before rainfall and the historical water level Hih after rainfall. And the ratio (Hih-Hiq) / Si of the difference (Hih-Hiq) and the area Si is determined as the historical unit rising water level His of the rainfall. After obtaining the historical unit rising water level His and the historical rainfall Ris of at least two historical rainfalls, the processor can fit all the historical unit rising water levels His and the historical rainfall Ris to obtain the first function His=0.00015Ris+0.006.

[0063] The processor can obtain the predicted daily maximum temperature within the next 7 days (i.e., the first preset future time length), and determine whether the predicted daily maximum temperature is higher than 38° C. for more than three consecutive days. If the predicted daily maximum temperature is higher than 38° C. for more than three consecutive days, the processor can adjust the first standard water level based on Table 2.

[0065] Reproductive Stage Green period Tillering period Booting stage Heading and flowering period Grouting period <![CDATA[H b1 ]]> 3cm 4cm 4cm 8cm 8cm

[0066] For example, if the predicted daily maximum temperature is higher than 38°C for more than three consecutive days, the processor can b1 ) is adjusted from 3cm to 4cm. The processor can obtain the current water level Hh of the planting area as 2cm. The current water level Hh is less than the adjusted first standard water level of 4cm, and the processor can obtain the predicted rainfall data Ris' for the second day (i.e., the second preset future duration). And determine the unit rising water level His' for the second day based on the predicted rainfall data Ris' and the first function His=0.00015Ris+0.006. After obtaining the unit rising water level His', the processor can determine the product His'*Si between the unit rising water level His' and the area Si, and determine the sum of the current water level Hh and His'*Si as the predicted future water level Hh+His'*Si for the second day. When the predicted future water level Hh+His'*Si is less than the adjusted first standard water level of 4cm, the processor can determine the difference (4cm-His'*Si) between the adjusted first standard water level 4cm and His'*Si, and determine the irrigation amount based on the difference. When the measured future water level Hh+His'*Si is greater than or equal to the adjusted first standard water level of 4 cm, the processor can determine that the planting area does not need irrigation.

The processor can obtain the current water level Hh of the planting area as 2cm. The current water level Hh is less than the second standard water level of 3cm, and the processor can obtain the predicted rainfall data Ris' of the second day (i.e., the second preset future duration) according to the processor. And determine the unit rising water level His' of the second day according to the predicted rainfall data Ris' and the first function His=0.00015Ris+0.006. After obtaining the unit rising water level His', the processor can determine the product His'*Si between the unit rising water level His' and the area Si, and determine the sum of the current water level Hh and His'*Si as the predicted future water level Hh+His'*Si of the second day. When the predicted future water level Hh+His'*Si is less than the second standard water level of 3cm, the processor can determine the difference (3cm-His'*Si) between the second standard water level 3cm and His'*Si, and determine the irrigation amount according to the difference. When it is predicted that the future water level Hh+His'*Si is greater than or equal to the second standard water level of 3 cm, the processor can determine that the planting area does not need irrigation.
