Technical Field

[0001] The utility model relates to the field of soil detection, and in particular to a soil fertilizer nitrogen content detection device. Background Art

[0002] In modern agricultural production, the nitrogen content in soil fertilizer is one of the key factors affecting crop growth and yield. Appropriate nitrogen fertilizer can not only significantly improve crop yield and quality, but also avoid environmental problems caused by excessive application of chemical fertilizers, such as groundwater pollution and greenhouse gas emissions. Therefore, timely and accurate detection of nitrogen content in soil fertilizer is of great practical significance for guiding agricultural production and optimizing fertilizer application.

[0003] In recent years, with the development of sensor technology and microelectronics technology, soil fertilizer nitrogen content detection devices based on new detection technologies such as ion selective electrodes and electrochemical sensors have gradually emerged. These devices usually have the advantages of small size, low cost, and easy operation, and are suitable for rapid on-site detection.

[0004] However, the above-mentioned detection device is only used for detection. The soil to be tested needs to be processed before detection, such as oscillating and mixing the soil solution. After the soil solution is prepared, other test solutions need to be added and then manually shaken for about 5 minutes. The manual preparation method is not only time-consuming and labor-intensive, but also has large deviations in the test results. Utility Model Content
