Problems solved by technology

[0002] In recent years, with the continuous growth of population, economic development and continuous improvement of urbanization level, the contradiction between supply and demand of water resources has become increasingly acute. my country’s agricultural irrigation water consumption is large, and the efficiency of farmland water irrigation is low, and the level of automation is low. At the same time, the use of chemical fertilizers in agricultural production Unreasonable and low utilization rate, resulting in an imbalance of soil nutrient ratio, insufficient phosphorus and potassium fertilizers, and deterioration of soil structure and soil microbial system
[0003] The future development trend of water irrigation technology is automation, precision, and intelligence. By 2020, my country's high-efficiency water-saving irrigation area has reached 288 million mu, ranking in the forefront of the world. However, my country's water-saving irrigation technology still has the following three shortcomings: 1. , The degree of automation is not high, that is, the existing drip irrigation products are mainly drip irrigation pipes, drip irrigation belts, sand and gravel filters, etc. Although there are but not many irrigation automation products, there are problems such as high cost and difficulty in field power supply; 2. Signal transmission Difficulties, that is, the mobile phone signal coverage in the field area is not complete, and high-stalk crops interfere with signal transmission; Third, the degree of intelligence is insufficient, that is, the current water-saving drip irrigation operation still relies on expert experience, lacking automatic perception of the environment and intelligent control of the drip irrigation system

Embodiment 1

[0038] refer to figure 1 , which is the first embodiment of the present invention, provides a water pump irrigation method, specifically comprising:

[0039] S1: Based on the analytic hierarchy process, the crop benefit is taken as the target layer, and a mathematical model is established.

[0040] S2: Determine the weight distribution relationship among soil moisture, temperature, pH, and conductivity of the soil suspension.

[0041] S3: The decision maker compares the various factors of the criterion layer to determine the weight of the program layer.

[0042] When using the AHP, it is necessary to construct an ideal comparison matrix, including:

[0043] Prove that the ideal comparison matrix has only one non-zero eigenvalue, which is the largest eigenvalue;

[0044] Solve the eigenvector of the largest eigenvalue, each element of which is exactly the weight value of each influencing factor;

[0045] According to the weight value, the influence degree of each influencin...

Embodiment 2

[0138] refer to Figure 2 to Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it provides a water pump irrigation system, which specifically includes:

[0139] An irrigation device 100 . The irrigation device 100 includes a multi-stage filter device 101 , a novel Venturi fertilizer applicator 102 and an integrated pressure-compensated dripper 103 .

[0140] The control device 200, the control device 200 includes a combined high-precision sensor, which is used to collect field data in real time and upload it to the host computer.

[0141] The multi-stage filter device 101 is used to remove most impurities in water and fertilizers, reducing the possibility of dripper clogging from the source.

[0142] The new Venturi fertilizer applicator 102 is used for efficient and uniform injection of waste materials, thereby realizing high-efficiency water and fertilizer integration.

[0143] The integrated ...
