Description

Technical Field

[0001] The present invention relates to a plant experimental planting box for root flushing and a control method thereof, belongs to the field of flushing preparation, and is particularly suitable for a plant experimental planting box with root flushing function and the preparation thereof. Background Art

[0002] In the study of plant ecology and soil science, the construction of plant communities, interspecific relationships between plants, and feedback mechanisms between plants and soil are important research areas. These studies not only help us understand the function and stability of ecosystems, but also provide a scientific basis for practical applications such as agriculture, forestry, and ecological restoration. In order to explore these issues in depth, researchers usually need to conduct plant planting experiments and conduct detailed analysis of the root traits of plants after the experiments.

[0003] The root system is an important part of plants. It is not only responsible for absorbing water and nutrients, but also establishes a complex interaction between plants and soil. The morphological characteristics of the root system, 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] At present, when researchers conduct root sampling, they usually use the method of manually pulling water pipes to flush to remove soil and impurities on the surface of the roots. Although this method can achieve the purpose to a certain extent, it also has some significant disadvantages. First, the manual flushing operation of pulling water pipes is not convenient enough, especially when dealing with larger planting boxes, the experimenters need to spend a lot of time and energy, resulting in low work efficiency. Secondly, the wastewater generated during the flushing process not only increases the complexity of the experiment, but may also have a certain impact on the environment. In addition, long-term manual operation can easily lead to fatigue of the experimenters, thus affecting the accuracy and reliability of the experiment.

[0005] In summary, the study of plant community construction, interspecific relationships, and feedback mechanisms between plants and soil requires efficient and convenient root sampling technology. This field urgently needs to introduce new technologies and automated equipment to help researchers better measure root traits, thereby promoting in-depth research and application in related fields.

That is, the greater the pressure, the greater the opening of the electronic valve, and the smaller the pressure, the smaller the opening of the electronic valve, which is beneficial to protecting the root system from damage.

[0031] Preferably, the water filtered through the coarse filter and the fine filter flows back to the input end of the water pump to achieve the reuse of water resources.
