As shown in fig. 1, an irrigation decision method, the main flow of which is described as follows (steps S101 to S105): step S101, obtaining current soil moisture content information of target soil;
in this embodiment, soil moisture content sensors are buried in different depths of the target soil, and are used for collecting soil moisture content information of soil layers of different depths of the target soil in real time, the soil moisture content sensors send the soil moisture content information to electronic equipment, and the electronic equipment refers to the received soil moisture content information as current soil moisture content information, wherein the current soil moisture content information comprises a first current soil moisture content of the target soil.
The method is characterized in that when the soil moisture content sensors in the target soil can detect that the current soil moisture content information changes, the current soil moisture content information of one soil moisture content sensor is not changed, then the soil moisture content sensor is judged to be damaged, the soil moisture content sensor needs to be replaced timely, so that the acquired accurate qualitative property of the front soil moisture content information is ensured, powerful data support is provided for irrigation of the target soil, the electronic equipment can store the corresponding position information of each soil moisture content sensor, a positioning module can be installed for each soil moisture content sensor, the specific limitation is not made on the positioning module, and when the soil moisture content sensor is damaged, the position of the soil moisture content sensor in the target soil can be rapidly determined through the position information stored by the electronic equipment or the position information uploaded by the positioning module.
Step S102, obtaining crop types corresponding to target soil;
in this embodiment, the electronic device stores crop types corresponding to each target soil, where when crops are planted in the target soil, a worker needs to input the crop types into the electronic device through a mouse, a keyboard, a touch screen and other modes of the electronic device, the electronic device binds the crop types with corresponding soil moisture sensors, and the soil moisture sensors can monitor the target soil corresponding to the crop types in real time.
Crop species include, but are not limited to, corn, wheat, and vegetables.
Step S103, obtaining water demand corresponding to the crop types;
specifically, the current growth stage of the crop species is obtained; and determining the water demand corresponding to the crop type based on the current generation stage.
Since the water demand required for the growth of each type of crop is different, the water demand of each type of crop in different growth phases is also different, and thus the growth phase of the crop needs to be acquired, and the electronic device takes the acquired growth phase of the crop as the current generation phase.
The timer can be used for timing when crops are planted, the timer uploads timing data to the electronic equipment in real time, and the electronic equipment determines the current growth stage of the crops according to the calculation data.
In this embodiment, a crop is taken as an example for explanation, and the growth stage of the crop is divided into a first growth stage, a second growth stage, a third growth stage and an nth growth stage, and the depths of the main distribution soil layers of the root system are a, b and c in sequence from shallow to deep, which are specifically set as follows:
a first growth stage: taking the soil moisture content of the depth of the layer a as a decision basis, wherein the upper limit value of the water demand is m, and the lower limit value of the water demand is n;
and a second growth stage: setting the upper limit value of water demand as m 'and the lower limit value of water demand as n' by taking the soil moisture content of the depth of the layer b as a decision basis;

In this embodiment, x is generally an integer of 5 or less.
Specifically, when the irrigation amount of the target soil is enough, deep seepage or surface runoff can be generated, and then the water content in the target soil gradually decreases along with surface evaporation and deep seepage, so that a smooth decreasing curve can be formed by using the historical data of soil moisture content information collected by the soil moisture content sensor after the target soil is fully irrigated, and the inflection point of the curve is the field water holding rate (thetac): namely, the maximum water content of the soil which does not generate deep leakage. With the seepage and evaporation of irrigation water, the water content of the soil is continuously reduced, and when the water content is lower than a certain value, the water content can inhibit the growth of crops. Wherein, the upper limit value of the water demand is larger than the field water holding rate, and the field water holding rate is taken as the upper limit value of the water demand.
And step S104, determining an irrigation strategy for the target soil based on the current soil moisture content information and the water demand.

The first preset water quantity threshold value is larger than 0, so that the target soil can normally provide water quantity for crops, the possibility of crop withering is reduced, and the first preset water quantity threshold value can be determined for (upper water quantity limit-lower water quantity limit) ×30%.
In this embodiment, the irrigation amount is determined by the first current soil moisture content and the upper water demand limit, and in this embodiment, the second water demand difference is calculated by calculating the second water demand difference between the first current soil moisture content and the upper water demand limit, and the second water demand difference is used as the irrigation amount.
