[0002] Soil physical and chemical properties, acidity and alkalinity, trace elements, enzyme activity, types and quantity of microorganisms all play an important role in the growth of ginseng. Nowadays, the area of ​​farmland ginseng cultivation is increasing, and farmland ginseng cultivation has particularly strict requirements on soil. The quality and yield of ginseng are closely related to the fertility of the ginseng bed soil. Therefore, studying the nitrogen, phosphorus, potassium and related enzyme activities at different depths of farmland ginseng cultivation soil during the leaf fall period and understanding the degree of ginseng soil changes are of great significance for the future soil selection for farmland ginseng cultivation.

[0003] When analyzing soil, it is necessary to prepare soil solutions of different concentrations according to different analytical experiments. The traditional method of preparing soil solutions is to use an electronic scale to weigh a preset weight of soil, add the weighed soil to a conical flask, and add a preset volume of sterile water to the conical flask to prepare a soil solution of a preset concentration. However, when preparing soil solutions in laboratories, the required soil mass is measured in grams, generally a few grams. When weighing the soil, it is also necessary to use a test paper pad on the electronic scale. During the preparation process, there is soil loss. At the same time, due to the accuracy limitation of the electronic scale, when preparing soil solutions, the solution preparation accuracy is not high, which affects the experimental accuracy.

[0057] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] Figures 1 to 3 As shown, an embodiment of the present invention provides a multi-concentration soil solution preparation device, the solution preparation device comprising:

[0059] A body 100, wherein a control unit is disposed on the body 100, and the control unit is used to obtain the concentration of the solution that the user needs to prepare;

[0060] A first preparation unit provided on the body 100, the first preparation unit comprises a first oscillating part 200, a weighing component 300, a liquid storage bottle 400 and a water adding part 700, the water adding part 700 is used to add sterile water to the liquid storage bottle 400, the weighing component 300 is used to weigh the weight of the soil in the liquid storage bottle 400, the first oscillating part 200 is used to oscillate the liquid storage bottle 400, the control unit obtains the weight of the soil added to the liquid storage bottle 400 through the weighing component 300, and adds a corresponding volume of solution preparation water to the liquid storage bottle 400 through the water adding part 700, and at the same time, the liquid storage bottle 400 is oscillated by the first oscillating part 200 to prepare a concentrated solution, the concentration of the concentrated solution is higher than the concentration of all solutions that the user needs to prepare;

[0061] The second preparation unit is arranged on the body 100, and the second preparation unit absorbs the high-concentration soil solution and dilutes the high-concentration soil solution into the concentration required by the user according to the user's needs.

[0062] In this embodiment, when the user prepares the soil solution, the user inputs the concentration of the soil solution to be prepared into the control unit and adds the soil to the liquid storage bottle 400. When adding the soil, the user does not need to measure the mass of the soil, as long as the estimated soil weight is greater than the weight of the soil required for the solution to be prepared. After the user adds the soil, the weight of the liquid storage bottle 400 increases, and the weighing component 300 measures the change in the liquid storage bottle 400, thereby calculating the weight of the soil added by the user. The control unit controls the water adding part 700 to add a corresponding volume of sterile water to the liquid storage bottle 400 based on the weight of the soil. The first oscillating part 200 oscillates the liquid storage bottle 400 to complete the preparation of the concentrated solution. The second preparation extracts the prepared concentrated solution, and adds sterile water to the concentrated solution through the water adding part 700 to dilute the concentrated solution to the concentration required by the user.

[0063] The multi-concentration soil solution preparation device disclosed in the embodiment of the present invention prepares soil into a concentrated solution first and then dilutes it into a solution of required concentration. Compared with the traditional device, it can prepare soil solutions of various concentrations, and there is no need to weigh a fixed amount of soil according to the required concentration each time. Moreover, a larger dose of soil can be used at one time, and the soil can be prevented from sticking to the test paper when a small dose of soil is weighed at a time or the preparation error caused by the weighing error can be prevented, thereby improving the preparation accuracy and preparation efficiency of the soil solution.

[0064] Specifically, in this embodiment, Figure 3 As shown, the body 100 is composed of a combination of plate-like materials, such as stainless steel. The body 100 is composed of a horizontal partition 103, a cover plate 104 and a rear cover plate 105. The rear cover plate 105 is vertically arranged.

[0065] like Figure 3 and Figure 4 As shown, the first oscillating part 200 is arranged inside the body 100, the cover plate 104 is provided with a first operating window penetrating from the side, the upper and lower ends of the first operating window are sealed by a horizontal partition 103, and an opening is provided on the horizontal partition 103 at the lower end of the first operating window, and the first oscillating part 200 includes:

[0066] A first oscillating seat 210, wherein the first oscillating seat 210 is cylindrical with an opening at one end, and the liquid storage bottle 400 is fixedly connected to the interior of the first oscillating seat 210;

[0067] A plurality of magnetic groups 220 (six magnetic groups 220 are provided in this embodiment) located outside the first oscillation seat 210, the magnetic groups 220 are evenly distributed around the axis of the first oscillation seat 210 in the circumferential direction, and the plurality of magnetic groups 220 form a frustum-shaped structure;

[0068] A plurality of coil groups 230 (six coil groups 230 are provided in this embodiment) fixedly connected to the outside of the magnetic group 220, the coil groups 230 are evenly distributed around the axis of the first oscillation seat 210 in the circumferential direction, the inner side of the coil group 230 is conical, and the magnetic group 220 and the coil group 230 form an electromagnetic rotation structure;

[0069] A first magnetic block 250 fixedly connected to the bottom of the first oscillating seat 210 and a second magnetic block 260 connected to the body 100, the first magnetic block 250 and the second magnetic block 260 repel each other, and when the liquid storage bottle 400 is oscillated, the coil assembly 230 is supplied with a current of periodically changing magnitude to drive the first oscillating seat 210 to rotate and vibrate up and down at the same time;

[0070] Specifically, in this embodiment, a cylindrical mounting seat is provided inside the cover plate 104, the coil group 230 is fixedly connected to the mounting seat by gluing, a frustum-shaped space is formed inside the coil group 230, the first oscillation seat 210 is a hard non-ferromagnetic material, such as ABS plastic, aluminum, austenitic stainless steel, etc., the first oscillation seat 210 and the magnetic group 220 are fixedly connected by welding or gluing, the first oscillation seat 210 and the magnetic group 220 are located inside the frustum-shaped space formed by the coil group 230, and the coil group 230 and the magnetic group 220 form a cone.

[0071] It should be noted that, although the liquid storage bottle 400 will sink after adding soil, the repulsive force between the first magnetic block 250 and the second magnetic block 260 will increase, but relative to the first oscillating part 200 and the weighing assembly 300, the repulsive force between the first magnetic block 250 and the second magnetic block 260 is an internal force, and the entire first oscillating part 200 and the weighing assembly 300 only add soil, and the gravity of the soil increases the external force. Therefore, the proximity of the first magnetic block 250 and the second magnetic block 260 will not affect the measurement result of the weighing assembly 300;

[0072] During oscillation, the voltage at both ends of the coil group 230 changes periodically, so that the coil group 230 generates a magnetic field of periodic magnitude. Since the first magnetic block 250 and the second magnetic block 260 repel each other, and the magnetic group 220 is conical, when the coil group 230 generates a magnetic field, a downward thrust is also generated on the magnetic group 220, and the downward thrust changes periodically, so that the coil group 230 moves up and down periodically, and the coil group 230 drives the magnetic group 220 to move up and down reciprocatingly, thereby oscillating the liquid in the liquid storage bottle 400;
