Description

Technical Field

[0001] This utility model relates to the field of soil fertility testing technology, and in particular to a portable online soil fertility testing device for alpine pastures. Background Technology

[0002] Fertility is the essential characteristic and fundamental attribute of soil. There is currently no universally accepted definition of soil fertility. Soil fertility is a comprehensive reflection of the physical, chemical, and biological properties of soil. Nutrients are the material basis of soil fertility, temperature and air are environmental factors, and water is both an environmental and nutrient factor. Various fertility factors (water, fertilizer, air, and heat) coexist, are interconnected, and mutually restrictive. Therefore, soil fertility can be summarized as follows: Soil fertility is the ability of soil to consistently and timely supply and coordinate the air, temperature, nutrients, and non-toxic substances required for plant growth.

[0003] Utility model patent application number 202020285052.9 discloses a soil fertility testing device, including a mounting base, a display screen, a battery, and a data processing module. A handle is bolted to the top of the mounting base, and the display screen is embedded in the upper surface of the mounting base. The battery and data processing module are housed inside the mounting base, and a testing cylinder is adhered to the bottom of the mounting base. Soil nutrient sensors, temperature sensors, and humidity sensors are installed at equal intervals on the inner wall of the testing cylinder. A movable groove is formed at the bottom edge of the mounting base, and the top of an outer protective sleeve is connected to the movable groove. A positioning block is adhered to the top edge of the outer protective sleeve, and an inner protective sleeve is embedded in a limiting plate, located outside the testing cylinder. This portable soil fertility testing device can perform real-time soil testing, while also providing protection for internal electrical components and allowing for soil sample collection.

[0004] While this soil fertility testing device can test soil at different depths, the depth of the testing cylinder is limited, thus limiting the reference value of the tests at different depths. Furthermore, although a baffle is installed below the sensor, soil can still fall into the gap between the sensor and the baffle, making it difficult to clean and potentially affecting subsequent testing.

[0005] Utility model patent application number 202321456483.7 discloses a soil fertility testing device, including a base plate. An installation box is fixedly installed on the top left side of the base plate. A guide plate is fixedly installed on the left side of the inner cavity of the installation box. A protective plate is fixedly installed on the right side of the inner cavity of the installation box. Fixing plates are fixedly installed on the right side of the guide plate and the left side of the protective plate. An electric turntable is movably installed in the middle of the inner side of the fixing plate. A connecting shaft is fixedly connected to the middle of the inner side of the electric turntable. A stirrer is fixedly installed on the surface of the connecting shaft. A U-shaped plate is fixedly installed at the bottom of the inner cavity of the installation box. This soil fertility testing device, through the guide plate, facilitates the guidance of soil entering the installation box, allowing it to flow quickly to the surface of the U-shaped plate. The protective plate effectively protects the inner wall of one side of the installation box.

[0006] However, the equipment uses a U-shaped plate to hold the soil. When the mixer is mixing the soil, some soil may be carried out of the U-shaped plate and fall into the gaps of the equipment, making it difficult to clean. In addition, the equipment is relatively large and inconvenient to carry for field operations. Utility Model Content
