[0002] Greenhouses are springing up all over my country. Using greenhouses to grow vegetables is not affected by seasons. The off-season vegetable supply also enriches people's food choices. In order to ensure the healthy growth of vegetables, irrigation is required. Early irrigation methods used traditional water diversion channels to cover and irrigate the planting pits of plants. This method wastes more water and has a slow irrigation efficiency.

[0003] A Chinese patent (CN202320787972.4) discloses a greenhouse water-saving irrigation system, comprising: a greenhouse main body; a top cover, the top cover is detachably connected to the greenhouse main body, the bottom of the top cover is detachably connected to a water tank, and a water inlet pipe is installed at the front end of the water tank; a cross pipe, the cross pipe is set to two, the two cross pipes are respectively installed on both sides of the top cover, and multiple atomizing nozzles are installed on the two cross pipes.

[0004] The technical solution disclosed in the above patent guides water into a horizontal pipe and then sprays it from the top of the greenhouse through an atomizing nozzle. This method has a small water output and a large spraying range, and cannot effectively irrigate the planting pit.

[0005] If water pipes are used to directly irrigate the planting pits, when the plants mature and are harvested, the land cannot be plowed when other plants are planted. The laid water pipes need to be removed before re-plowing, which is time-consuming. Utility Model Content
