[0031] Example 2:

[0032] On the basis of the first embodiment, the variable distance mechanism further includes a drip irrigation unit;

[0033] The drip irrigation unit includes a movable plate 7, a through slot 701, a water pipe 1 601, a telescopic hose 602, a water pipe 2 603, a dripper 604, a water pump 605, and a connecting pipe 606. Both sides of the movable plate 7 are fixedly connected to sliders 508. The movable plate 7 slides onto the connecting base 501, serving as the carrier for the drip irrigation unit. The movable plate 7 is connected to the adjustment unit via a connecting block 506 for position adjustment. The left end of water pipe 1 601 is fixedly connected to the left connecting base 501.

A dripper 604 is connected to the bottom of telescopic hose 602. A slider is fixedly connected to the back of the dripper 604, which slides into the through slot 701. Multiple drippers 604 are equidistantly connected to the bottom of telescopic hose 602, ensuring uniform irrigation for all parts of the blueberry plant. The sliding part on the back of the dripper 604 slides in the through groove 701, which is convenient for fine-tuning the position of the dripper and enhancing the flexibility of the drip irrigation system. The water pump 605 is arranged inside the storage box 1 to provide power, pump out the nutrient solution in the storage box 1, and transport it to the dripper 604 through the pipeline for irrigation.

According to the position or planting density of the blueberry plants to be irrigated, the threaded rod 505 is driven to rotate by the motor 2 503 to adjust the position of the movable plate 7 in the slide 502, thereby adjusting the irrigation range of the dripper 604. The sliding part fixedly connected to the back of the dripper 604 can slide in the through groove 701. The inclination angle of the bottom of the through groove 701 is different, which is convenient for adjusting the spacing between the drippers 604. In this way, the user can fine-tune the position of the dripper according to the actual growth of the blueberry plants to enhance the flexibility and adaptability of the drip irrigation system.

[0035] Start water pump 605 to pump out the nutrient solution from storage tank 1 and deliver it to dripper 604 through a pipe. Dripper 604 evenly drips the nutrient solution onto the roots of the blueberry plants. During irrigation, the nutrient solution level is monitored in real time through a transparent observation window to ensure timely replenishment. The irrigation volume and frequency are adjusted appropriately based on the growth of the blueberry plants and weather conditions.

[0036] After irrigation, clean the storage tank 1, mixing cylinder 2, and pipes in a timely manner to prevent nutrient solution residue from causing blockage or corrosion. Regularly check the wear of each component and replace damaged parts in a timely manner to ensure the normal operation of the drip irrigation system.
