[0053] A plurality of solar power generators 34 and solar heating tubes 35 are arranged on the top of the plurality of guide columns 3, a circulation pump 36 is arranged on the top of the heating box 7, and one end of the solar heating tube 35 is connected to the drainage port of the circulation pump 36, and the other end of the solar heating tube 35 and the water intake port of the circulation pump 36 both extend to the interior of the heating box 7;

[0054] The first delivery pipe 15 and the second delivery pipe 16 are both elastic hoses;

[0055] The outer wall of the inner drip irrigation pipe 21 is in close contact with the inner wall of the outer drip irrigation pipe 24;

[0056] The solar energy is converted into electric energy by the solar generator 34, and the drip irrigation device is powered by the power grid. The two sets of electric sliders 2 slide on the two sets of slide rails 1 respectively to adjust the position of the drip irrigation mechanism. Then, the two sets of first electric cylinders 5 are contracted to penetrate the ground film and pierce the steel bar 23 into the ground, so that the second drip irrigation holes 25 on the outer drip irrigation pipe 24 are all located underground. Then, the drive motor 27 is turned on, and the gear 28 is meshed with the gear ring 26 to drive the outer drip irrigation pipe 24 to rotate, and the second drip irrigation holes 25 on the outer drip irrigation pipe 24 are aligned with the first drip irrigation holes 22 on the inner drip irrigation pipe 21. The discharge direction is adjusted, the water inlet valve 9 is connected to the water source, the water inlet valve 9 and the first electric control valve 10 are opened, and the piston 1 is contracted by the second electric cylinder 13. 2 rises, sucks water into the heating box 7 and filters impurities in the water through the filter plate 8, then closes the water inlet valve 9, opens the circulation pump 36 to make the water in the heating box 7 circulate in the heating box 7 and the solar heating tube 35, heats the water through the solar energy, and heats the water through the heating box 7. At the same time, the second electric cylinder 13 extends to make the piston 12 slide downward, pressurizes the heating box 7, and after steam is generated, the steam passes through the first delivery pipe 15, the connecting pipe 20 and the inner drip irrigation pipe 21 in sequence, and then sprays the steam into the soil, and drives the outer drip irrigation pipe 24 to rotate, aligns a row of second drip irrigation holes 25 on the outer drip irrigation pipe 24 with other rows of first drip irrigation holes 22 on the inner drip irrigation pipe 21, and heats the soil in different directions. After sterilization, the two groups of first electric cylinders 5 are extended, the inner drip irrigation pipe 21 is reset, and the electric slider 2 slides to sterilize the soil at the position at high temperature. After the soil cools down, salvia miltiorrhiza can be planted. Then, during the growth of salvia miltiorrhiza, the water inlet valve 9 is closed, and the second electric cylinder 13 is extended to make the piston 12 slide downward, pressurize the heating box 7, and make the water pass through the first delivery pipe 15, the connecting pipe 20 and the inner drip irrigation pipe 21 in turn, and then the steam is dripped into the soil, and the roots of salvia miltiorrhiza are dripped in a three-dimensional manner. When water accumulates in the field, due to long-term drip irrigation of the roots of salvia miltiorrhiza, multiple holes are formed around the roots of salvia miltiorrhiza, and water gathers in the holes. Then the steel drill 23 is extended into the hole, and the lifting frame 30 is moved by the extension of the third electric cylinder 29. When the water reaches the bottom of the inner drip irrigation pipe 21, the second electric cylinder 13 is contracted to make the piston 12 slide upward, so that negative pressure is formed inside the heating box 7, and the water is discharged into the sewage pipe 33 through the sewage suction pipe 32, and then the water is discharged into the second delivery pipe 16 through the sewage pipe 33. In the process of the movement of the lifting frame 30, the inner wall of the inner drip irrigation pipe 21 is cleaned by the annular scraper 31, and then the water in the heating box 7 is discharged through the water inlet valve 9. The second electric cylinder 13 is extended to make the piston 12 slide downward, and the pressure in the heating box 7 is increased. The air passes through the first delivery pipe 15, the connecting pipe 20 and the inner drip irrigation pipe 21 in turn, and then the air is sprayed around the roots of Salvia miltiorrhiza to replenish air for the roots of Salvia miltiorrhiza and reduce the decay of the roots of Salvia miltiorrhiza, thereby improving the practicality of the equipment.
