Background

Along with the development of modern agriculture in a daily and monthly manner, in the large-area water-saving irrigation agricultural fertilization production, a solid fertilizer is usually fertilized by adopting a high-efficiency water-saving irrigation pipeline to install a fertilization tank or a quantitative pre-dissolution water-fertilizer integrated machine. The flow of the main irrigation pipeline is easily reduced, the fertilizer application amount per mu is not uniform, the capillary or the spray dripper close to the fertilizer application tank is easily blocked due to incomplete dissolution, the fertilizer efficiency of the spray dripper is not uniform, and the fertilizer is wasted. Along with the development trend of land intensification, refinement and high efficiency, growers have higher and higher requirements on crop refinement and high-efficiency management. The planting concept of planting area benefit is converted into the concept of planting area benefit, mu benefit and plant benefit, and good crop fertilizers are accurately fertilized to each plant of crops, so that accurate fertilization of large-area land is more and more important for farmers. However, the existing solid fertilizer diluting and fertilizing device still has the following problems:

1): the fertilizer tank is used for diluting solid fertilizer, and pipeline water flow pressure is needed to be flushed, so that the pressure and flow of an irrigation main pipeline are reduced.

2): the fertilizer application amount per mu is not uniform.

3): the specific fertilization position is uncertain, and the fertilizer efficiency of the specific fertilization position is uncertain.

4): the capillary or the spray nozzle close to the fertilizing tank is easy to be blocked due to incomplete dissolution.

5): because of the uncertainty of the solid particle water and fertilizer melting state time period in the tank body, the fertilizer efficiency is inconsistent in different time periods, and the fertilizer efficiency cannot be accurately applied to each plant of crops.

6): the irrigation position is changed in the irrigation process, so that uneven elements of front and rear irrigation fertilizer are easily caused.

7): the fertilizer which is left in the tank body and is not thoroughly dissolved needs to be discharged for secondary irrigation application, so that waste is caused.

8): the fertilizing tank body has limited volume, is frequently applied, has high labor intensity and low automation degree.
