Tomato plug tray seedling watering device

Abstract

The present invention relates to a tomato plug tray seedling watering device, comprising a top plate, wherein a baffle plate is arranged on the lower surface of the top plate; a distribution pipe, wherein the distribution pipe is connected to an external water source, a plurality of distribution outlets are provided on the distribution pipe, the water outlet directions of the distribution outlets are vertically downward and face a seedling tray, and the spacing between adjacent distribution outlets is the same as the spacing between seedling holes on the seedling tray; interception mechanisms, wherein, except for two distribution outlets located at both ends of the distribution pipe, each of the remaining distribution outlets corresponds to one interception mechanism; and a driving part, wherein the driving part is connected to the distribution pipe. According to the present invention, the distribution pipe is driven by the driving part to reciprocate once along the length direction or the width direction of the seedling tray, such that tomato seedlings at the edge are watered twice, while tomato seedlings on the inner side are watered only once, thereby avoiding the situation in which, due to faster moisture loss at seedling holes located at the edge of the seedling tray, tomato seedlings at the edge grow weaker and shorter than those in the middle, and being beneficial to the uniform growth of tomato seedlings.
