Reasonable nutrient management not only helps to improve crop yield and quality, but also prevents environmental pollution caused by excessive fertilizers and protects the health of water bodies and ecosystems. Soil nutrient content testing is the basis for achieving sustainable management of land resources, which helps to reasonably arrange planting structure and farming methods and maintain the long-term productivity of the soil.

The rotation of the stirring shaft 23 drives the several stirring rollers 25 on it to rotate around the stirring shaft 23. The stirring rollers 25 stir the soil mixture so that the nutrients in the soil sample are fully dissolved in the extraction liquid. At this time, the temperature control heater 28 is driven to control the appropriate temperature to conduct heat energy through the heat pipe 27 to the inner wall of the heating tank 26, and then conduct it from the heating tank 26 into the shell 1 The inner wall of the soil mixture is temperature-controlled and heated to promote better dissolution of nutrients in the extract.

There is no need to use a variety of instruments and tools for experiments. The automated stirring and temperature control facilitate the staff to complete the detection and extraction of soil nutrients better and faster, thereby improving efficiency.

[0038] By setting up the sealing mechanism 3, the staff grasps the handle 311 to open the sealing door 310, pours the soil sample into the shell 1, and then closes the sealing door 310. At this time, the staff grasps the self-locking handle 37 to press the block 38 at one end of the groove 36 into the self-locking handle 37, compresses the spring 39, and then rotates the self-locking handle 37 to drive the shaft 34 to rotate in the fixed block 35.

After the extract completely immerses the soil sample, At the same time, the self-locking handle 37 is rotated to drive the butterfly valve plate 33 to close the feed pipe 32, release the block 38, and the spring 39 rebounds to drive one end of the block 38 to slide into the groove 36 of the fixed block 35, completing the self-locking, and realizing the use of the device in a sealed state.

[0039] By setting up the discharge mechanism 4, when the nutrients in the soil are fully dissolved in the extracting liquid under the action of the extraction mechanism 2, the liquid pump 43 on the receiving plate 29 is driven to pump the soil mixture in the shell 1 to the filter 42 on the connecting pipe 41. The mixture contacts the filter 42, and the filter 42 sieves out the solid soil components and continues to remain in the shell 1, while the liquid nutrient mixture dissolved in the extracting liquid enters the connecting pipe 41 from the filter 42, and flows out from the discharge pipe 44 through the pumping of the liquid pump 43 to enter the subsequent detection process. The extraction effect is achieved through the drive of the liquid pump 43 and the solid-liquid separation of the filter 42.
