[0002] Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. Integrated water and fertilizer is to use a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type, and then mix them with irrigation water through a controllable pipeline system to supply water and fertilizer. After the water and fertilizer are mixed, drip irrigation is formed through pipes and drippers to evenly, regularly, and quantitatively infiltrate the root development and growth area of ​​the crop, so that the main root soil always remains loose and has an appropriate water content. However, the existing integrated water and fertilizer irrigation equipment is not convenient for reliable fertilizer concentration ratio when used, and there are still some problems when using it.

[0003] However, there are still some problems when using the existing intelligent water-fertilizer integrated machine with adjustable fertilizer concentration:

[0004] There is a water-fertilizer integrated machine for water-saving irrigation with a Chinese patent application number of CN202321907613.4, which belongs to the technical field of water-fertilizer integrated machines. The technical scheme thereof includes a water-fertilizer integrated machine mixing tank, a mixing mechanism is arranged inside the water-fertilizer integrated machine mixing tank, a feed hopper is fixedly connected to the top of the water-fertilizer integrated machine mixing tank, a motor is fixedly connected to the bottom of the water-fertilizer integrated machine mixing tank, and mixing blades are arranged inside the water-fertilizer integrated machine mixing tank;

[0006] 2. When using the existing integrated water and fertilizer machine, it takes time for water and fertilizer to merge. If the liquid is discharged during watering, it is easy to cause uneven mixing of water and fertilizer. When the mixing is completed, draining the liquid after completion will inevitably affect the efficiency of watering.

[0007] In response to the above problems, an innovative design was carried out based on the original intelligent water-fertilizer machine with adjustable fertilizer concentration. Summary of the invention
