Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of collecting equipment, in particular to a potting device capable of in-situ collection of root exudates. BACKGROUND

[0002] Plant root exudates refer to chemical substances released by plant roots during growth into the soil. These exudates have a great impact on the health and growth of the plant itself and the surrounding environment, including nutrient absorption, antibacterial effect, symbiotic interaction with microorganisms, regulation of soil pH, and influence on soil structure. In addition, they also have great significance in crop genetic optimization and improvement.

[0003] Existing in-situ collection of root exudates potting devices mostly require manual digging and soil stripping by experimenters, but the operation space is small, which can easily damage the remaining roots. The sampling device is not convenient to place, and it is difficult to simulate different experimental environments, which is not sufficient to support actual needs. Therefore, a potting device capable of in-situ collection of root exudates is proposed, which has the advantages of being able to perform partial root soil stripping sampling at any position in the device, adjusting the planting height according to the plant type, adjusting the humidity to simulate different environments, etc. SUMMARY
