Description

Technical Field

[0001] The utility model relates to the field of greenhouse seedling cultivation, in particular to a greenhouse seedling cultivation sprinkler device. Background Art

[0002] Greenhouse planting is a planting technology that is a scientific planting method used to cultivate strong seedlings.

[0003] When using a greenhouse for seedling cultivation, it is necessary to water the seedlings in the greenhouse regularly. In the existing technology, watering is done either by manually pulling a water pipe into the greenhouse or by installing a fixed sprinkler head inside the greenhouse. Manual watering requires more manpower and affects the watering efficiency. When watering with a fixed sprinkler head, the watering range is limited to the watering range of the sprinkler head, thereby affecting the watering range and failing to evenly sprinkle water on the seedlings inside the greenhouse, which is inconvenient for people to use. For this reason, we propose a greenhouse seedling watering device. Utility Model Content
