Description

Technical Field

[0001] The utility model relates to the technical field of soil microbial activity monitoring tools, in particular to a soil microbial activity monitoring device. Background Art

[0002] Microorganisms are an important part of the soil ecosystem. They play a vital role in the soil ecosystem, such as decomposing organic matter, promoting nutrient circulation, maintaining soil structure, etc. Soil microbial activity is one of the important indicators for evaluating soil quality and monitoring soil health. When planting Chinese medicinal materials, in order to promote the growth of Chinese medicinal materials more luxuriantly and to timely understand the activity of microorganisms in the soil, it is usually necessary to monitor the activity of soil microorganisms. When performing monitoring operations, corresponding activity monitoring devices are usually used.

[0003] There are many types of soil microbial activity monitoring devices on the market. Most of them use soil respiration meters to complete the measurement operation. This type of soil respiration meter evaluates the soil respiration rate by measuring the amount of carbon dioxide released by the soil, and then understands information such as soil microbial activity and organic matter decomposition rate.

[0004] Specifically, a soil respiration meter usually includes a sealed soil sample chamber and a carbon dioxide detector. The instrument monitors changes in carbon dioxide concentration in the sample chamber and calculates the soil respiration rate based on this change.

[0005] However, most soil microbial activity monitoring devices, although they can use the soil sample chamber to store samples for measurement operations, lack components that can keep warm and moisturize. Failure to keep warm and moisturize will affect the survival rate and vitality of soil microorganisms, further affecting the accuracy of the measurement results, and causing inconvenience to users. In view of this, we propose a soil microbial activity monitoring device. Utility Model Content
