It is an important production material in agricultural production; generally divided into organic fertilizers, inorganic fertilizers, and biological fertilizers. According to the components contained, it is divided into nitrogen fertilizers, potassium fertilizers, trace element fertilizers, and rare earth element fertilizers.

[0003] Soil fertility grading refers to dividing the soil into different grades according to the level of soil fertility. To rationally utilize soil resources, improve and fertilize the soil, give full play to the soil production potential, and achieve sustainable soil utilization, certain soil characteristics are selected as indicators to comprehensively evaluate the ability of the soil to supply and coordinate water, nutrients, ventilation conditions, and temperature conditions in terms of quantity and quality.

[0049] In the embodiments of the present invention, please refer to Figures 1 - 7 、 Figure 9 、 Figure 10 and 14 and Figure 15 : A flexible fertilizer mixer applied to different fertility soil areas, including a fertilizer mixing tank 1 assembled on a base assembly 2, and the fertilizer mixing tank 1 includes an auxiliary mixing component 100, a mixing tank body 200 and a main mixing component 300; the mixing tank body 200 divides a main mixing cavity 210, a side auxiliary material mixing cavity 220 and a transition mixing cavity 230 inside it;

[0050] There are multiple side auxiliary material mixing cavities 220, and the multiple side auxiliary material mixing cavities 220 are located outside the main mixing cavity 210 and are distributed in a circular array along the circumference; the transition mixing cavity 230 is located at the main mixing cavity 210 and is used to connect the main mixing cavity 210 and the side auxiliary material mixing cavity 220; the side auxiliary material mixing cavity 220 is provided with multiple material passing cavities 241 on the side close to the main mixing cavity 210, and the multiple material passing cavities 241 are equidistantly distributed along the side auxiliary material mixing cavity 220, and the material passing cavities 241 are used to connect the main mixing cavity 210 and the side auxiliary material mixing cavity 220;

[0051] The mixing path of multiple fertilizers to be mixed inside the mixing tank body 200 is described as follows: The multiple fertilizers to be mixed first enter from one end of the main mixing chamber 210, and enter the transition mixing chamber 230 at the other end along the inner cavity of the main mixing chamber 210, and then are dispersed and distributed into multiple side auxiliary material mixing chambers 220 through the transition mixing chamber 230, and move along the inner cavity of the side auxiliary material mixing chambers 220. During this process, they are dispersed and introduced into the main mixing chamber 210 again through multiple material passing chambers 241;
