[0033] It should be noted that in the process of tobacco planting and management, ensuring a balanced supply of nutrients is a crucial link. This is not only directly related to the healthy growth of tobacco plants, but also has a profound impact on their disease resistance, final yield and the quality of tobacco leaves. However, for a long time, tobacco fertilization management, especially the key link of water and fertilizer topdressing, has required manual digging of small holes near the roots of the tobacco each time fertilization is applied, and then the fertilizer solution is poured in using tools such as kettles or cups. This process requires repeated bending and squatting, which consumes a lot of physical energy for the operators, especially in large-scale planting areas. This high-intensity labor can easily lead to fatigue and decreased efficiency. In summary, a tobacco quantitative water and fertilizer topdressing device is needed to solve the above problems.

[0036] In this embodiment, the assembly plate 10 is mounted on the metering bottle 8 and serves as an intermediate platform for connecting the metering bottle with components such as the positioning rod. Angle brackets are fixed to the assembly plate 10 and are threadedly connected to the metering bottle 8 via screws, ensuring a secure connection between the assembly plate and the metering bottle 8. The positioning rod 11 is fixed to the assembly plate 10 and is the core component of the positioning mechanism. The positioning rod 11 is used to be inserted deep into the soil layer.

The stirring blade 14 stirs the water-fertilizer mixture through the centrifugal force generated by rotation, so that the fertilizer and water therein are fully mixed and evenly distributed, ensuring a balanced distribution of nutrients; the motor 15 is assembled on the top of the mixing tank 2 and serves as the power source of the mixing mechanism. The output shaft of the motor 15 is fixedly connected to the rotating shaft 13 through a coupling, realizing the transmission of motor power to the rotating shaft and the stirring blade. When the motor is started, it will drive the rotating shaft and the stirring blade 14 to rotate together, thereby achieving the purpose of stirring the water and fertilizer.

A hinged cover is attached to the top of the hopper 17. When closed, the cover seals the hopper 17, preventing foreign matter from entering the mixing tank and contaminating the water-fertilizer mixture. When additional fertilizer is needed, the operator can easily open the cover and pour the fertilizer into the hopper 17.

[0043] In a further preferred embodiment of the present invention, a water injection pipe 18 is provided on the mixing tank 2. The water injection pipe 18 is used to connect a water supply device to inject water into the mixing tank 2. A water valve is provided on the water injection pipe 18.

[0044] In this embodiment, the mixing tank 2 is equipped with a water injection pipe 18, which is a conduit for connecting to an external water supply.
