Description

Technical Field

[0001] The utility model relates to the technical field of rice, in particular to a sampling device for rice fertility detection. Background Art

[0002] Rice is one of the important food crops in the world and plays a vital role in ensuring global food security and improving human living standards. The main reason for measuring rice fertility is to maximize and optimize resource utilization, and to supply the required nutrients in a timely manner in accordance with the growth law of crops, thereby improving rice yield and quality. By testing soil and formulating fertilizers, farmers can understand the nutrient content and fertilizer supply performance of the soil, and then determine a suitable fertilization plan, which can not only meet the various nutrients required for rice growth, but also avoid fertilizer waste and environmental pollution. The soil around rice is full of rice roots, which are usually concentrated on the soil surface or at a specific depth. Their presence will lead to uneven distribution of nutrients in the soil, which may result in different nutrient contents when sampling at different depths or locations, affecting the final test results. There are usually a large number of microorganisms around the root system, which participate in soil nutrient circulation and transformation together with the root system. Therefore, the presence of the root system may affect the activity and nutrient circulation of microorganisms in the soil, thereby affecting the fertility test results. The existing sampling device for rice fertility detection cannot process the rice root system when testing and sampling the soil, resulting in inaccurate test results. Utility Model Content
