[0033] A method for using a drip irrigation device for soybean cultivation in saline-alkali land, the method comprising the following steps:

[0034] S1: The water pipe is fixedly connected to the open end of the water inlet pipe 1-2-1, and the water is filtered through the filter 1-2-2 and then flows into the water tank 1-1 for storage;

[0035] S2: The electric telescopic rod 3-2 is powered on to extend and adjust the spacing between the multiple piercing units 3-1;

[0036] S3: Insert the piercing column 3-1-1 into the soil, and rotate the spraying nozzle 3-1-6 so that the spraying hole 3-1-5 coincides with the piercing column hole 3-1-2;

[0037] S4: Power on water pumps 2-7 for drip irrigation.

[0038] The working principle of the present invention is:

[0039] When in use, the water pipe is fixedly connected to the open end of the water inlet pipe 1-2-1, and then water is injected into the water inlet pipe 1-2-1 through the water inlet pipe 1-2-1. The incoming water pushes the scraper 1-2-4 to move rightward, and at the same time, the spring telescopic rod 1-2-3 contracts. The water is filtered through the filter screen 1-2-2 and flows into the water tank 1-1 for storage. When the water is full, the water pipe is closed, and the scraper 1-2-4 is reset by the action of the spring telescopic rod 1-2-3. When the scraper 1-2-4 is reset, impurities adhering to the filter screen 1-2-2 can be scraped off. At the same time, the sewage outlet 1-2-5 is opened, and the impurities can be discharged through the sewage outlet 1-2-5. The device is connected to an external power source. When in use, multiple electric telescopic rods 3-2 are powered on and extended to adjust the spacing between multiple piercing units 3-1. After the spacing is adjusted, the piercing column 3-1-1 is inserted into the soil, and the sliding plate 3-1-7 blocks the piercing column hole 3-1-2 to prevent soil from entering the piercing column 3-1-1. When the piercing column 3-1-1 is completely inserted into the soil, the spraying pipe mouth 3-1-6 is rotated to drive the spraying pipe 3-1-4 to rotate, so that multiple of the above-mentioned piercing units 3-1-3 are all slid into the piercing column hole groove 3-1-3. At this time, the spraying hole 3-1-5 coincides with the piercing column hole 3-1-2, and the water pump 2-7 is powered on to suck the water in the water tank 1-1 out through the liquid inlet pipe 2-6 into the mixing box 2-1, and then flows out from the liquid outlet pipe 2-10, passes through the liquid separation plate 2-11 and the hose, and enters the spraying pipe 3-1-4, and then It is sprayed out from the spray hole 3-1-5 and sprayed into the soil through the piercing column hole 3-1-2 to complete drip irrigation. The above steps can be reversed to take out the piercing column 3-1-1 for storage or to prepare for the next drip irrigation. When fertilizing or spraying pesticides is needed, the box containing fertilizer or pesticide powder is fixedly connected to the feed pipe 2-8. When in use, the feed pump 2-9 is energized. After the feed pump 2-9 sucks out the powder in the box containing fertilizer or pesticide powder, it is fed into the liquid inlet pipe 2-6 through the feed pipe 2-8. The powder flows into the mixing box 2-1 along with the water in the liquid inlet pipe 2-6. At the same time, the water impacts the paddle 2-4, driving the rotating shaft 2-3 to rotate. The rotation of the rotating shaft 2-3 drives the stirring column 2-5 to rotate. The rotation of the stirring column 2-5 can fully mix the water and the fertilizer and pesticide powder, and then feed them into the spray pipe 3-1-4 for spraying. It can avoid premature mixing of water with fertilizers or pesticides, which may cause precipitation or reduce the efficacy of fertilizers or pesticides.
