Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil acidity and alkalinity detection, in particular to soil acidity and alkalinity detection equipment. Background Art
[0002] Soil pH includes two aspects: acid strength and acid quantity, or active acidity and potential acidity. Acid strength refers to the H concentration in the soil solution in equilibrium with the soil solid phase, expressed as pH. Acid quantity refers to the total amount of acid and buffering performance, representing the total amount of exchangeable hydrogen and aluminum contained in the soil. Generally, the exchangeable acid scale is used. Soil pH has a great influence on soil fertility and plant growth. Many soils in northwest and northern my country have high pH values, while red soils in the south have low pH values. When testing the pH of the soil, pH testing equipment is needed. Soil pH testers are widely used in soil pH testing, dryland water-saving irrigation, precision agriculture, forestry, geological exploration, plant cultivation, water conservancy, environmental protection and other fields.
[0003] The Chinese patent publication number is: CN218470724U discloses a soil pH detection device. The application states: "Existing soil pH detection equipment usually follows the following set of processes: first, use a sampling device to sample the soil; then stir and dissolve the sample in a stirring device with neutral water to form a sample solution; then use a pH detector to easily detect the sample. Under this process, the soil pH detection equipment is usually large in size and inconvenient to carry out for field testing. At the same time, the existing detection equipment has a single function and can only realize a single pH detection function or a combination of several functions. It is often necessary to use other auxiliary equipment to complete some steps in the above process before the sample soil can be tested on site and the pH value of the soil can be obtained." Although this application solves this problem, it has the following defects:
[0004] The above-mentioned existing technical solutions have the following defects: although the above-mentioned detection equipment can independently complete the whole set of soil pH detection operations and also reduce its volume for easy carrying, there is a lack of protection measures on the outside of the water tank and the sampling tube. The detection equipment is easy to fall during carrying, which leads to a higher damage rate of the water tank and the sampling tube in the detection equipment, increasing its cost. Therefore, we propose a new type of soil pH detection equipment. Utility Model Content
