[0002] Currently, flue-cured tobacco transplanting and after transplanting need to use seedling fertilizer and special topdressing, and the two kinds of fertilizers need to be mixed into water-soluble fertilizer solution. The water-soluble fertilizer solution is a mixed solution obtained by mixing seedling fertilizer or special topdressing according to the required proportion, which is different from traditional fertilizers and has the characteristics of fast absorption and high utilization rate, and can promote the early growth of tobacco seedlings. In order to ensure the rapid growth of tobacco seedlings after transplanting and enhance the disease resistance and stress resistance of tobacco seedlings, the use of seedling fertilizer and special topdressing is promoted in flue-cured tobacco cultivation. The promotion rate of flue-cured tobacco seedling fertilizer and special topdressing is 100%.

[0003] During the current transplanting process and after transplanting, the tobacco farmers mainly pour the fertilizer into the fertilizer cup and then pour the fertilizer water in the fertilizer cup into the soil around the tobacco plant when applying the seedling fertilizer and the special topdressing for flue-cured tobacco. This method has the following problems: first, the tobacco farmers need to bend down to operate, which is labor-intensive; second, the fertilizer water is poured on one side of the tobacco plant during fertilization, which leads to uneven distribution of the fertilizer water and affects the growth and development of tobacco leaves.

[0024] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0025] Please refer to Figures 1 to 7 The water and fertilizer solution fertilizer applicator of the embodiment comprises a fertilizer application assembly, the fertilizer application assembly comprises a dosing cylinder 11, a vertical pipe 12 installed at the bottom of the dosing cylinder 11, and a ring application pipe 13 installed at the bottom of the vertical pipe 12, the ring application pipe 13 is annular with a notch, and the bottom of the ring application pipe 13 is provided with fertilizer application holes 14 at intervals in the circumferential direction. It should be noted that the size of the ring application pipe 13 can be determined according to the fertilizer application distance, and the size of the notch is larger than the size of the stem at the bottom of the tobacco plant, so that the ring application pipe 13 can be sleeved around the tobacco plant, and the height of the vertical pipe 12 is about 1 meter, so that the tobacco farmer can complete the operation without bending over.

[0026] After the above-mentioned fertilizer application assembly is adopted, the ring application pipe 13 can be sleeved around the stem of the tobacco plant during fertilizer application, and then the fertilizer water can be applied to the soil through the dosing cylinder 11, the vertical pipe 12 and the fertilizer application holes 14. Compared with the prior art, the fertilizer applicator can realize fertilizer application operation without bending over, and the fertilizer water can be uniformly applied to the soil around the tobacco plant, thereby improving the absorption efficiency of the root system of the tobacco plant to the fertilizer water.

[0027] In order to facilitate operation, the fertilizer applicator further comprises a switch assembly, which comprises a telescopic rod 21, a plug 22 and a spring 23. The telescopic rod 21 is movably installed in the vertical pipe 12, and there is a certain space between the telescopic rod 21 and the inner wall of the vertical pipe 12. The top end of the telescopic rod 21 extends upward to the dosing cylinder 11 and is connected with the plug 22. The hole diameter of the inner bottom of the dosing cylinder 11 is larger than the hole diameter of the telescopic rod 21. The size of the plug 22 is larger than the hole diameter of the inner bottom of the dosing cylinder 11. The bottom end of the telescopic rod 21 extends downward from the bottom of the ring application pipe 13 by a distance, and the lower rod diameter of the telescopic rod 21 is the same as the hole diameter on the ring application pipe 13, so as to minimize the outflow of the fertilizer water. The spring 23 is sleeved outside the telescopic rod 21, and the two ends of the spring 23 are respectively connected with the bottom of the plug 22 and the upper end of the ring application pipe 13. Under the action of the spring 23, the telescopic rod 21 is contracted and moved downward in the natural state, so that the plug 22 abuts against the inner bottom of the dosing cylinder 11, thereby preventing the fertilizer water in the dosing cylinder 11 from flowing out. When the telescopic rod 21 is pressed downward to the ground, the telescopic rod 21 moves upward under the reaction force of the ground, so that the plug 22 is away from the inner bottom of the dosing cylinder 11, and then the fertilizer water in the dosing cylinder 11 can flow out through the vertical pipe 12 and the ring application pipe 13.

[0028] A rubber ring 24 is provided around the bottom periphery of the plug 22, which can improve the sealing effect between the plug 22 and the metering cylinder 11 when the telescopic rod 21 retracts downward.

[0029] To facilitate fertilization, the fertilization assembly also includes a fertilizer supply pipe 15 and a backpack electric sprayer 16. The fertilizer supply pipe 15 is connected to the hose of the backpack electric sprayer 16 and is also connected to the metering cylinder 11, so that fertilizer solution can be supplied to the metering cylinder 11 through the backpack electric sprayer 16. By using it in conjunction with the backpack electric sprayer 16, the flow rate of the fertilizer solution is faster, and the fertilization efficiency is higher.

[0030] For ease of operation, a handle 17 is provided on the metering cylinder 11, through which the fertilizer tube 15 passes and communicates with the inside of the metering cylinder 11, allowing the fertilizer applicator to be operated via the handle 17.

[0031] To facilitate the application of fertilizer and water, limiting blocks 18 are provided on both sides of the fertilizer hole 14 at the bottom of the ring pipe 13. The limiting blocks 18 extend downwards a certain distance to prevent the fertilizer hole 14 from directly contacting the soil, thereby allowing the fertilizer hole 14 to be applied smoothly.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
