[0002] Irrigation needs to be adjusted according to the demand of crops, soil moisture content and climatic conditions to achieve the best irrigation effect. Excessive irrigation will not only waste water resources, but also lead to the loss of nutrients in the soil and soil salinization, which will have an adverse effect on crop growth. During the irrigation process, nutrients necessary for crops can be added to ensure normal growth of crops.

[0003] The Chinese utility model with announcement number CN216674154U discloses an irrigation device capable of quantitative water injection. After quantitative injection through a quantitative scale, a control valve is opened to deliver water and liquid medicine to an irrigation box. The stirring motor is turned on to drive a stirring rod to mix and stir the inside of the irrigation box, thereby improving the irrigation efficiency, facilitating quantitative stirring and mixing, and improving the irrigation effect. The water and liquid medicine in the irrigation box are driven into an irrigation pipe by turning on a pressure pump, and crops are irrigated through an irrigation head. The telescopic cylinder can be opened according to the height of the crop to drive the bottom plate to adjust its height, thereby facilitating the operation of the staff and reducing the burden on the staff. The utility model is worthy of popularization and use.

[0004] Although the above technical solution can fully mix the agent and water during use, it cannot quantify the added agent according to the fertility of the soil, which will lead to a decrease in soil fertility and affect the growth and yield of crops.
