Compared to traditional trench fertilization, gas blast fertilization evenly distributes fertilizer throughout the soil, improving fertilizer utilization.

[0003] However, the existing gas explosion fertilization equipment has a fixed gas explosion pressure and cannot be adjusted according to soil conditions. It has poor adaptability to soil conditions, the fertilizer distribution range cannot be controlled, and it is difficult to ensure the quality of fertilization, which limits its promotion and application.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] An embodiment of the present invention provides a method for precise control of the range of gas explosion fertilization. In order to illustrate the method, the gas explosion pressure prescription model that supports the implementation of the method is first introduced. Taking into account that soils with different moisture contents and compaction have different mechanical properties, this embodiment will match different gas explosion pressures according to soil moisture content and compaction to control the fertilizer distribution range and ensure the fertilization effect. The gas explosion pressure prescription model is used to characterize the relationship between gas explosion pressure, soil moisture content, soil compaction and fertilizer diffusion diameter. The model can be obtained by an experimental method. In a specific embodiment, the experimental process may include the following steps:

[0026] First, a 3-factor 5-level uniform design experiment was designed with soil moisture, soil compaction, and gas explosion pressure as factors and fertilizer diffusion diameter as response. The standard U5(5 3 ) table, as shown in Table 1.

[0027] Table 1 Gas explosion test data

[0028] serial number Moisture content W / % Firmness C / Mpa Gas explosion pressure P / Mpa Fertilizer diffusion diameter D / mm 1 12.1 0.43 0.6 190 2 14.7 0.87 0.4 105 3 18.2 0.26 0.7 268 4 21.3 0.67 0.5 181 5 23.9 1.05 0.8 131

[0029] Before the test, cylindrical soil samples with a diameter of 300 mm and a height of 350 mm were prepared. The moisture content was adjusted by adding water, and the compaction was adjusted by compaction. The moisture content of the samples was measured using a probe-type soil sensor, and the compaction of the samples was measured using a compaction meter.

[0030] During the test, the gas explosion depth was 250mm, and the gas explosion pressure, moisture content and compactness were set according to the test plan to carry out the gas explosion test.

[0031] After the test, the soil sample was split longitudinally into two parts, and the diameter of the cavity formed by the gas explosion was measured to characterize the fertilizer diffusion diameter. The data are shown in Table 1.

[0032] According to the data in Table 1, a standardized ridge regression model is constructed, as shown in formula (1), which is transformed into a prediction model for gas explosion pressure P, as shown in formula (2).

[0033] D=208.63+5.40W-223.82C+34.86P(1)

[0034]

[0035] Where, P-gas explosion pressure, MPa;

[0036] D-fertilizer diffusion diameter, mm;

[0037] W-soil moisture content, %;

[0038] C-soil compaction, MPa.

[0039] Finally, two soil samples were prepared using the same method, and the moisture content and compaction were measured as shown in Table 2. The fertilizer diffusion diameter was set to 200 mm. Based on the model output gas explosion pressure, a verification test was conducted to measure the actual fertilizer diffusion diameter. The results are shown in Table 2, and the relative errors were all within an acceptable range.

[0040] Table 2 Verification test data

[0041]

[0042] Based on the gas explosion pressure prescription model shown in formula (2), Figure 1 This is a flow chart of a method for accurately controlling the range of gas explosion fertilization provided by an embodiment of the present invention. Figure 1 As shown, the method specifically includes:

[0043] S110 : Obtain a target value of the fertilizer diffusion radius, and detect the current soil moisture content and soil compaction.

[0044] The target value of the fertilizer diffusion radius is the desired fertilization range. In this embodiment, the range is first obtained, and the moisture content and compactness of the soil to be fertilized are detected in real time.

[0045] Optional, such as Figure 2 As shown, a push rod can be used to penetrate the soil with a probe sensor, which then measures soil moisture. During penetration, a pull-pressure sensor measures the resistance generated, which represents the penetration resistance of the probe sensor. Finally, soil compaction data is fed back based on the soil resistance. Specifically, the ratio of the resistance to the probe diameter represents soil compaction.

[0046] S120: Calculate the gas explosion pressure required to reach the target value based on the soil moisture content and soil compaction.

[0047] The target values of soil moisture content, soil compaction, and fertilizer diffusion radius collected in S110 are substituted into the gas explosion pressure prescription model shown in formula (2) as W, C, and D, respectively. The calculated P is the gas explosion pressure required to achieve the target values.

[0048] S130: Control the air pump to inflate the gas storage tank so that the gas pressure in the gas storage tank reaches the required explosion pressure.

[0049] Specific, combined Figure 3 The controller controls the air pump to turn on by controlling the relay to inflate the air tank; a pressure sensor is used to sense the pressure in the air tank during inflation; when the pressure reaches the explosion pressure output by the explosion pressure prescription model, the air pump is controlled to turn off by controlling the relay to stop inflation.

[0050] S140: Utilize the gas storage tank to perform a normal gas explosion fertilization process to control the fertilization range of the gas explosion.

[0051] In summary, this embodiment provides a method for precisely controlling the range of gas explosion fertilization. Taking into account the different mechanical properties of soils with different moisture contents and compaction levels, this method matches different gas explosion pressures based on soil moisture content and compaction, precisely controlling the fertilizer distribution range and ensuring effective fertilization. This method can sense soil conditions, adapt the gas explosion pressure, and precisely control the gas explosion fertilization range to ensure fertilization quality.
