[0002] The interaction between plant roots and their surrounding environment is a key area of research in ecology, agricultural science, and environmental science; plants release various organic and inorganic compounds into the soil through their roots, which are collectively referred to as root exudates.
[0003] Root exudates include sugars, amino acids, and organic acids. These exudates have a significant impact on soil microbial community structure, nutrient availability, and plant-soil interactions. Currently, research on root exudates mainly relies on hydroponic or soil-based experiments. However, these methods struggle to precisely control the types and quantities of exudates and cannot simulate the dynamic changes in root exudates under natural conditions. This makes it difficult to conduct experiments that study the effects of plant root exudates on soil microorganisms, nutrient cycling, and plant growth.
[0004] Therefore, developing a simulated root exudate device that can adapt to multiple water levels is of great significance for in-depth research on the ecological functions of root exudates. Utility Model Content

[0029] In the following description, only certain exemplary embodiments are depicted simply. As will be appreciated by those skilled in the art, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0031] Please see Figure 1 This invention illustrates a specific embodiment of a simulated root exudate device adaptable to multiple water levels. This device can precisely control the type and concentration of root exudates, simulating the dynamic changes of root exudates under natural conditions. It provides a reliable experimental tool for studying the ecological functions of root exudates, and makes the simulated root system more robust, preventing shaking. It is suitable for any soil water level and solves the problems of traditional simulated root devices that require specific water levels and cannot precisely control root exudates.
[0032] like Figure 1As shown, a simulated root exudate device adaptable to multiple water levels includes a culture chamber 1 filled with water and soil, a simulated root system 2 vertically installed in the culture chamber 1, and an exudate injector 3 connected to the top of the simulated root system 2. The culture chamber 1 includes a fixed structure 11 connected to the simulated root system 2 and a stabilizing structure 12 disposed at the bottom of the culture chamber 1, the stabilizing structure 12 being connected to the bottom of the simulated root system 2. The exudate injector 3 is pushed to inject the exudate into the simulated root system 2, the simulated root system 2 simulating the process of root exudate release in the natural environment, and releasing the exudate into the culture chamber 1.
[0033] Understandably, the culture chamber 1 is filled with soil, the simulated root system 2 is buried in the soil, and water is injected into the culture chamber 1. The amount of water injected can be controlled according to experimental needs. This simulated root secretion device, which is adaptable to multiple water levels, fixes the simulated root system 2 through the fixed structure 11 and the stabilizing structure 12, and can be used in any soil water level situation.
[0034] The secretion is injected into the simulated root system 2 in the culture chamber 1 using a secretion syringe 3. The secretion syringe 3 may be equipped with a scale line to precisely control the injection volume of the secretion. The simulated root system 2 releases the secretion evenly into the soil of the culture chamber 1, which is used to study the effects of plant root secretions on soil microorganisms, nutrient cycling and plant growth.
[0035] Specifically, such as Figure 2 As shown, the fixed structure 11 is connected to the microframe structure 101 and is located at the upper end of the microframe structure 101. The fixed structure 11 is hollow, which facilitates the passage and fixation of the simulated root system 2, and fixes the simulated root system 2 in the middle position of the microframe structure 101.
[0036] Specifically, such as Figure 2 As shown, the stabilizing structure 12 is connected to the microframe structure 101 and is located at the lower end of the microframe structure 101. The stabilizing structure 12 has a recess in the middle to stabilize the simulated root system 2, prevent the simulated root system 2 from shaking, and ensure stable injection of secretions.
[0037] Specifically, the top of the simulated root system 2 is connected to a connecting pipe 4, and the input end of the connecting pipe 4 is equipped with a control component. The control component is connected to the injection end of the secretion syringe 3. Preferably, the control component is a three-way valve 5. The root secretion syringe 3 is connected through the three-way valve 5 to inject secretions and control the type and content of secretions.
[0038] It should be noted that this application controls the flow rate of secretions by setting a three-way valve. When the flow area between one valve core and the valve seat of the three-way valve increases, the flow area between the other valve core and the valve seat decreases, thereby precisely controlling the type and concentration of liquid root secretions.
[0039] Specifically, the simulated root system 2 is provided with multiple micropore structures 21. The simulated root system 2 secretes uniformly through the micropore structures 21. The secretions are injected into the culture chamber 1 through the secretion syringe 3 to simulate the dynamic changes of root secretions under natural conditions.
[0040] Preferably, such as Figure 1 As shown, the culture chamber 1 includes a micro-frame structure 101 and a front baffle structure 102. The micro-frame structure 101 and the front baffle structure 102 are detachably connected. The micro-frame structure 101 is designed as a concave structure, with one side open. The open side is spliced with the front baffle structure 102. The other sides of the concave structure and the front baffle structure 102 form a receiving groove 103 for placing soil.
[0041] Understandably, both the microframe structure 101 and the front baffle structure 102 are made of transparent acrylic material, and the microframe structure 101 and the front baffle structure 102 are combined and fixed with an adhesive film. The height of the culture chamber 1 is 14cm, the width is 10cm, and the thickness is 0.8cm. The fixing structure 11 and the stabilizing structure 12 are made of the same material as the microframe structure 101, which is acrylic material, making it easy to observe the root growth. Through the improvement of the culture box structure, the possibility of soil cultivation with different water contents has been increased. Regardless of whether the soil has high or low water content, cultivation can be carried out under any water level.
[0042] Although exemplary embodiments of the present invention have been shown in the foregoing disclosure, it should be noted that various changes and modifications may be made without departing from the scope defined by the claims. Furthermore, while the elements of the present invention may be described or claimed individually, it is also contemplated that multiple elements may be included, unless explicitly limited to a single element.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
