Description

Technical Field

[0001] The present invention relates to the technical field of soil nutrient detection, and particularly to a cultivated land soil nutrient detection device. Background Art

[0002] The nutrients in cultivated land soil refer to the substances in cultivated land soil that can provide essential nutrient elements for plant growth, mainly including macronutrients, secondary nutrients, micronutrients, and organic nutrients, etc. They play a crucial role in the growth and development of plants.

[0003] Soil type: Due to differences in factors such as parent material, topography, and climate of different types of soil, their nutrient content and composition are also different. For example, black soil is rich in organic matter and nitrogen, while red soil has a relatively high content of iron and aluminum oxides and a relatively low nutrient content.

[0004] Climatic conditions: Climatic factors such as temperature, precipitation, and sunlight will affect the transformation and cycling of nutrients in the soil. A warm and humid climate is conducive to the activities of soil microorganisms, accelerating the decomposition of organic matter and the release of nutrients; while a dry or cold climate will inhibit the activity of soil microorganisms and slow down the nutrient transformation process.

[0005] Cultivated land soil nutrient detection equipment plays an important role in modern agriculture, which can help farmers apply fertilizers scientifically and improve crop yield and quality. However, there are still some technical defects in the existing soil nutrient detection equipment in practical applications, which limit its popularization and effect.

[0006] The existing technology generally drives the cultivated land soil sampling to the laboratory for detection, but the traditional laboratory detection takes a long time and lacks timeliness.
