[0028] In the present invention, in order to enhance the stability of the water branch pipe 5 in the tobacco field, multiple positioning components are equidistantly provided on the outside of the water branch pipe 5. The positioning components include a limiting ring 13 provided on the top of the water branch pipe 5 and two second insertion rods 14 fixedly connected to the two ends of the limiting ring 13.

[0029] In the present invention, the water branch pipe 5 is laid in the tobacco field, a limiting ring 13 is inserted on the outside of the water branch pipe 5, and a second insertion rod 14 is inserted into the soil, which is beneficial to ensure the stability of the water branch pipe 5 to prevent it from moving due to the influence of wind when not in use, which brings the trouble of rearranging.

[0030] In the present invention, the connecting pipe 7 is installed near the root of the tobacco plant through the first insertion rod 9, and the fixed pipe 8 is inserted into the soil. The water is transported to the inside of the water supply main pipe 4 through the water inlet pipe 1, the pump body 2 and the delivery pipe 3. The water supply branch pipe 5 is used to transport the water to the tobacco field according to the planting conditions. The water inside the water supply branch pipe 5 is transported to the inside of the connecting pipe 7 through the first connecting pipe 6. The water flows into the soil through the drip irrigation port 10 and the fixed pipe 8, meeting the water demand of the tobacco plant and completing the irrigation work. By setting the drip irrigation port 10, the fixed pipe 8 and the first insertion rod 9, the drip irrigation process is carried out underground, which can effectively avoid the evaporation of water on the soil surface when drip irrigation is carried out on the surface, thereby improving the utilization efficiency of water resources.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
