Description

TECHNICAL FIELD

[0001] The present application relates to a plant experiment planting box for root washing and a control method thereof, and belongs to the field of washing preparation, and is especially suitable for a plant experiment planting box with a root washing function and a preparation thereof. BACKGROUND

[0002] In the study of plant ecology and soil science, the construction of plant communities, the relationship between plant species, and the feedback mechanism between plants and soil are important research areas. These studies not only help us understand the function and stability of the ecosystem, but also provide scientific basis for practical applications such as agriculture, forestry, and ecological restoration. In order to further explore these issues, researchers often need to conduct plant planting experiments and analyze the root traits of plants in detail after the experiment is completed.

[0003] Roots are an important part of plants, not only responsible for absorbing water and nutrients, but also establishing complex interactions between plants and soil. The morphological characteristics of roots, such as root length, root density, and root surface area, directly affect the growth and ecological adaptability of plants. Therefore, accurate measurement of root traits is crucial to understanding the physiological and ecological characteristics of plants.

[0004] Currently, researchers usually use manual water pipe flushing to remove soil and impurities on the surface of roots when sampling roots. Although this method can achieve the purpose to some extent, it also has some significant disadvantages. First, manual water pipe flushing is not convenient, especially when dealing with larger planting boxes, researchers need to spend a lot of time and effort, resulting in low work efficiency. Second, the waste water generated during the flushing process not only increases the complexity of the experiment, but also may have some impact on the environment. In addition, long-time manual operation can easily lead to fatigue of the researchers, thereby affecting the accuracy and reliability of the experiment.

[0005] In summary, the study of plant community construction, plant interspecific relationship, and feedback mechanism between plants and soil requires efficient and convenient root sampling technology. New technologies and automated equipment are urgently needed in this field to help researchers better measure root traits, thereby promoting in-depth research and application in related fields.
