Description

Technical Field

[0001] The utility model relates to the technical field of tobacco root irrigation, in particular to a touch-type controlled-quantity root irrigation device. Background Art

[0002] In recent years, the development of tobacco has undergone tremendous changes. Restricted by international and domestic tobacco control policies, the tobacco industry is facing unprecedented development pressure. The main root diseases of tobacco are root knot nematode disease and root black rot. In order to prevent root diseases, root irrigation is often required. It is best to add drip irrigation after root irrigation to facilitate the penetration of the liquid medicine into the roots of the plant; at the same time, the use of tobacco nutrient solutions such as soy milk can also be carried out through root irrigation.

[0003] There is a utility model patent application with application number 201520432652.2, titled "A tobacco root irrigation device with nutrient solution." The device comprises a nutrient solution storage tank, an infusion line connected to the tank, and a quantitative infusion device mounted on the tank. The quantitative infusion device includes a metering pump, a power supply, and a switch button located at the front end of the infusion line. The metering pump is mounted on the tank and connected to the switch button and the power supply, respectively. The infusion line is coupled to the metering pump. Prior art uses a metering pump coupled to a power supply to achieve quantitative root irrigation, resulting in high equipment costs. Utility Model Content
