Background

Drip irrigation is the use of plastic tubing to deliver water to the crop for localized irrigation through orifices or drippers on a capillary tube having a diameter of about 10 mm. Drip irrigation is the most effective water-saving irrigation mode in arid and water-deficient areas, and the water utilization rate can reach 95%. Compared with spray irrigation, the drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to improve the fertilizer efficiency by more than one time. Because of the lack of water in arid areas, the water melon seedlings are usually watered by gravity drip irrigation for cultivating the arch-shed watermelons in arid areas.

However, the prior art has the following defects in the using process: when the watermelon seedlings are cultivated in the arch shed, because the watermelon seedlings are cultivated artificially, the intervals among the watermelon seedlings can be different, and because the positions of the drippers of the traditional gravity drip irrigation device are not adjustable, when the drippers are far away from the rootstocks of the watermelon seedlings, the watermelon seedlings can not absorb water better, thereby being unfavorable for the growth of the watermelon seedlings and inconvenient to use.
