The invention relates to the technical field of
cherry tree planting, in particular to a
cherry tree water and
fertilizer spraying device which comprises a circulating
water pipe, a plurality of quantity control water tank mechanisms arranged on a circulating path of the circulating
water pipe, a spraying mechanism connected with the quantity control water tank mechanisms and cherry trees arranged in the spraying mechanism. The quantity control water tank mechanism comprises a protective shell arranged on the outer wall of the circulating
water pipe, the interior of the protective shell is rotationally connected with a flow direction adjusting
assembly, and the direction of a three-face
ball valve is adjusted by controlling a reset wheel, so that liquid in the circulating water
pipe can be input into a quantity control
liquid storage tank through a
liquid storage tank water conveying
pipe; when water and
fertilizer in the circulating water
pipe enter the quantity-controlled
liquid storage tank, the floating
ball valve assembly drives the three-face
ball valve to rotate, so that the circulating opening is changed, the water pipe of the
liquid storage tank is closed, the circulating water pipe is dredged, the water and
fertilizer in the circulating water pipe flow to the next quantity-controlled
liquid storage tank, and at the moment, the water and fertilizer in the quantity-controlled
liquid storage tank are quantitative; and the problem of non-uniform growth caused by non-uniform liquid distribution is avoided.
