Abstract

This invention relates to the field of Angelica sinensis seedling cultivation technology, and discloses a water and fertilizer irrigation device for Angelica sinensis greenhouse seedling cultivation. The device includes a main pipe and connecting pipes positioned opposite each other between greenhouse supports. The main pipe has several spray holes. A movable frame and a driving assembly that can drive the movable frame to slide along the axial direction of the connecting pipes are provided between the two opposite connecting pipes. The main pipe is located at the bottom end of the movable frame. Elastic seals are provided at the spray holes. A rotary sprinkler assembly that can be detachably installed at the spray holes on the main pipe allows the elastic seals to be opened and rotated for irrigation. The advantages of this invention compared to existing technologies are: easy adjustment of the irrigation range by moving the sprinkler, uniform irrigation, and ease of disassembly and maintenance.
