In the utility model adopting the above-mentioned technical solution, under normal conditions, the upper valve body is opened and the lower valve body is closed, the liquid in the liquid storage tank enters the drainage pipe, flows through the upper valve body, and stops at the lower valve body The distance D between them determines the quantity of liquid output; when in use, the upper linkage rod and the lower linkage rod rotate in a certain direction driven by the longitudinal linkage rod until the lower valve body is opened and the upper valve body is closed. At this time, the quantitative liquid between the upper valve body and the lower valve body will flow out through the taper opening at the front end of the drainage tube, and the upper valve body can prevent the liquid at the upper end from flowing down. After use, the upper linkage rod and the lower linkage rod rotate in reverse under the drive of the longitudinal linkage rod, so that a kind of water quantitative applicator for transplanting and rooting tobacco seedlings returns to the normal state, that is, the upper valve body is opened and the lower valve body is opened. The body is closed, and at this time, the upper end of the lower valve body can store liquid again, which is convenient for the next quantitative output of liquid.

It is further defined that the upper valve body and the lower valve body are ball valves, and the ball valve can effectively control the opening and closing of the upper valve body and the lower valve body within a range of 90 degrees of rotation through the rotation of the linkage assembly.

It is further defined that the length of the upper linkage rod is less than D, and this limitation effectively avoids interference caused when the upper linkage lever and the lower linkage lever rotate.

The benefits of the utility model: the utility model has the advantages of simple structure, convenient manufacture, strong practicability, effective control of fertilization amount, reduction of excessive waste of fertilizer, reduction of environmental pollution, and promotion of neat growth of plants at the same time.
