An intelligent measurement method and device for soil acidity and alkalinity based on the Internet of Things

Abstract

The invention discloses an intelligent measurement device for soil acidity and alkalinity based on the Internet of Things, which includes a device body, a feed control mechanism disposed above the interior of the device body, and a movable quick-measurement mechanism disposed below the interior of the device body; The feed control mechanism includes a feed hopper installed on the top of the device body and a turntable on the inner wall of one side of the device body. The turntable is located obliquely below the feed hopper, and a horizontally arranged moving frame is slidingly installed at the bottom of the feed hopper. , the bottom of one side of the moving frame close to the turntable is rotatably connected with a transfer rod, one side of the turntable is slidably connected with an active connecting rod, and one end of the active connecting rod is rotatably connected with one end of the transfer rod, and the feed hopper There are two oppositely arranged flow control plates connected with the rotation below. The invention has ingenious design, simple operation and low cost, is suitable for frequent soil acid-base measurement in experimental research, does not need manual loading and unloading, improves the quality and efficiency of soil acid-base measurement, and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of soil measurement, in particular to an intelligent measurement method and device for soil acidity and alkalinity based on the Internet of Things. Background technique [0002] Soil acidity includes two aspects of acidity strength and acidity quantity, or active acidity and potential acidity. Acidity refers to the concentration of H in the soil solution in equilibrium with the soil solid phase, expressed in pH. The amount of acidity refers to the total amount of acid and buffer performance, representing the total amount of exchangeable hydrogen and aluminum contained in the soil. It is generally expressed by the amount of exchangeable acid. Soil pH has a great impact on soil fertility and plant growth. Many soils in Northwest and North my country have high pH values, while red soils in southern China have low pH values. Therefore, crops and plants that are compatible with the pH of the soil can be grown....

Problems solved by technology

Soil pH also has a great impact on the availability of nutrients, such as the availability of phosphorus in neutral soils; the availability of trace elements (manganese, copper, zinc, etc.) in alkaline soils is poor

[0003] At present, the measurement method of soil acidity and alkalinity mainly relies on manual measurement using pH testing equipment, which is limited to a small-scale single pH measurement. There are certain limitations in the experimental research process, and the operation is cumbersome, and it is not convenient for multiple studies. It is not hygienic to use and affects the accuracy of the measurement results. Therefore, we propose an intelligent measurement method and device for the soil pH level based on the Internet of Things to solve the above problems
