Description

Technical Field:

[0001] The utility model belongs to the technical field of plant root observation, and relates to a hydroponic device convenient for plant root observation, which is used to simply and clearly observe plants throughout the growth cycle starting from seeds. Background Technique:

[0002] The root is an organ that grows downward during the long-term adaptation of some plants to terrestrial life. It has the functions of absorption, transportation, storage, and fixation. There are many types of plant roots, and the state of the roots will change differently during each growth cycle of the plant. With the increasing interest in botany among people and the need for modern agronomy to understand the roots, it has become particularly important to observe and study the growth environment and development status of plant roots. In the traditional process of observing plant roots, operators generally pull the plants out of the soil, further wash the soil adhering to the roots, and then perform subsequent operations such as drying and collection before making a comparative observation. This traditional operation method is time-consuming and laborious, and it is extremely easy to damage the plant roots during the operation, resulting in large errors and inaccurate results. Although the traditional hydroponic method can provide the nutrients required for plant growth, it is often difficult to directly observe the development process of the roots, and conventional hydroponic containers are mostly made of opaque materials, which cannot meet the need for intuitive observation.

[0003] In the prior art, Chinese Patent CN111226775A discloses a plant root observation device, including a growth box. The growth box is transparent, and a supporting box is arranged at the top of the growth box. The top of the supporting box has a flanging extending outward, and the flanging is placed on the top wall of the growth box; an observer is placed vertically in the growth box. This observation device can cultivate plants in a hydroponic way, so that the roots of the plants can be in a transparent medium, and an observer is arranged in the observation device, which is convenient for observing the plant roots.

[0004] Chinese Patent CN218604411U discloses a hydroponic device that is easy to move and observe the nodulation status of alfalfa roots, including a culture box, a transparent upper cover matching the culture box, and a transparent hydroponic cup placed in the culture box; the culture box is divided into a light-transmitting part and a light-shielding part by a horizontal light-shielding partition board. A placement hole is arranged on the light-shielding partition board, and the placement hole matches the transparent hydroponic cup; a light-shielding grid board is arranged in the transparent hydroponic cup. The area below the light-shielding grid board is the root growth area. The light-shielding grid board and the light-shielding partition board are at the same horizontal position. A liquid outlet is arranged at the bottom end of the transparent hydroponic cup, and a valve is arranged at the liquid outlet. In the technical solution of this utility model, the matching setting of the culture box and the hydroponic cup is adopted, which is easy to observe, and the alfalfa seedlings can be easily taken out without damaging the roots, and it is convenient to replace the nutrient solution. The materials of the whole hydroponic device are easily available, light in weight, and convenient to move; it is beneficial to observe the growth of plants, roots, and root nodules every day.

[0005] Chinese Patent CN206776376U discloses a hydroponic device for plant seedlings, comprising: a hydroponic box cover, a hydroponic box body, a liquid supplementing component, a liquid discharging component, an air pump and a liquid storage tank; the shading cloth of the hydroponic device is adjusted to facilitate shading and simulate the growth environment of the plant roots; the position of the planting plate in the hydroponic device can be automatically moved according to the length of the roots. By adjusting the position of the planting basket, while ensuring that the roots absorb sufficient nutrients and are breathable, the nutrient solution is saved; with the liquid level sensor and the liquid supplementing component, the automatic addition of the nutrient solution can be realized, saving labor; with the pH value measuring device and the liquid discharging component, the pH value of the nutrient solution can be monitored in real time to ensure quality; the solar LED supplementary light is used, which is environmentally friendly and practical.

The planting component is composed of a planting basket 5 and a porous hydroponic cloth 6. The planting basket 5 is sized to fit the hydroponic housing 1 and can just be stuck above the side wall of the hydroponic housing 1. The porous hydroponic cloth 6 is laid flat above the recess of the planting basket 5 for placing plant seeds and providing a rooting environment.
