Description

Technical Field

[0001] This utility model relates to the field of plant observation technology, and in particular to a plant root growth observation device. Background Technology

[0002] By observing the growth, morphology, and physiological phenomena of plants, we can gain a deeper understanding of their adaptability and survival mechanisms. These observations provide important scientific evidence for plant classification, cultivation, and protection, thereby enhancing our understanding of plant ecology and plant biology. When conducting research on plant root systems, plants need to be transplanted into special planting containers. These containers must have at least one transparent side, allowing users to observe the growth of plant roots under the soil for research purposes.

[0003] Because the planting container used for observation has at least one side that is transparent for the user to observe, light can also shine into the planting container through the transparent side, making it impossible for the planting container to accurately reproduce the dark environment inside the real soil, which reduces the reliability of the experimental results. At the same time, the existing planting container is not convenient for adjusting the water level. Utility Model Content

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-6 As shown, a plant root growth observation device includes an outer cylinder 1 and an inner cylinder 2. A water storage cavity 21 is provided in the middle of the inner cylinder 2. Multiple planting cavities 22 are evenly distributed in a ring array outside the water storage cavity 21. Multiple water passage holes 23 are provided on the side wall of the water storage cavity 21 and communicate with the inside of the planting cavities 22. The bottom of the water storage cavity 21 is hollow and communicates with the inside of the outer cylinder 1. The inner diameter of the water storage cavity 21 gradually increases from top to bottom, and a water inlet is formed at the top. Normally, it can be sealed with a cover plate to prevent water vapor from evaporating from the water storage cavity 21. At the same time, the evaporated water vapor enters the soil in the planting cavity 22 through the water passage holes 23, which can keep the soil in the upper part of the planting cavity 22 moist. The water passage holes 23 at the bottom can transport water from the water storage cavity 21 to the soil at the bottom of the planting cavity 22. An outer edge 24 is provided on the upper part of the outer surface of the inner cylinder 2. The outer edge 24 can be fastened to the upper end of the outer cylinder 1, which makes it convenient to place the inner cylinder 2 on the outer cylinder 1 and also convenient to remove.

[0016] The outer cylinder 1 has multiple water outlets 101 evenly distributed from top to bottom on its side wall. Each water outlet 101 is plugged with a sealing plug 4. A water level line with corresponding scale is set near the water outlet 101. When there is too much water in the outer cylinder 1, the sealing plug 4 near the corresponding scale water level line can be removed, and the water above this scale line will flow out through the water outlet 101 to avoid affecting the growth of the plant.

[0017] The outer cylinder 1 has a drain groove 102 on its side wall. A waterproof and airtight zipper 5 is fixedly installed on the outside of the drain groove 102. A water level scale line is set on one side of the waterproof and airtight zipper 5. When there is too much water in the outer cylinder 1, the waterproof and airtight zipper 5 is pulled down to the appropriate scale, so that the water above the zipper is discharged through the drain groove 102.

[0018] The outer cylinder 1 is made of black transparent plastic, which facilitates the observation of the plant roots inside the planting cavity 22. The use of black plastic can also block light, thus restoring the dark environment inside the real soil and ensuring the reliability of the experimental results. The inner cylinder 2 is made of white transparent plastic or transparent acrylic sheet, which allows for clear observation of the root system inside the planting cavity 22.

[0019] The water storage chamber 21 has a water level scale line on its side wall, which can be used to add or drain water in a timely manner according to the water level line.

[0020] The inner cylinder 2 is also equipped with a light-shielding device 3. The light-shielding device 3 includes a fixing ring 31 fixedly installed on the outer cylinder 1 and a fixing block 32 fixedly installed on the outer side of the fixing ring 31. The fixing block 32 has a storage cavity 321 in the middle. The side wall of the storage cavity 321 has an opening groove 322 that communicates with the fixing ring 31. A rotating rod 33 is rotatably installed in the middle of the storage cavity 321. A sunshade curtain 34 is fixedly installed on the outer surface of the rotating rod 33. The sunshade curtain 34 is wrapped around the outer surface of the rotating rod 33. The sunshade curtain 34 passes through the opening groove 322 and is fixedly installed with a sliding rod 35. The upper and lower ends of the sliding rod 35 slide in the upper and lower ring sliding grooves 311. Magnet pieces 37 are fixedly installed on both the left and right sides of the fixing block 32. A drive rod 38 is fixedly installed on the top of the rotating rod 33. The top of the drive rod 38 rotates through the fixing block 32 and is fixedly installed with a handle 39. An iron plate 36 is fixedly installed on the outer surface of the sliding rod 35.

[0021] In use, grasp the iron plate 36, then slide the sliding rod 35 within the circular groove 311, causing the sunshade curtain 34 to wrap around the outer cylinder 1, blocking the outer cylinder 1. Then, the iron plate 36 is attracted to the magnet 37 on the other side of the fixing block 32, thus forming a curtain around the outside of the outer cylinder 1, preventing sunlight from passing through the outer cylinder 1 and directly shining on the inner cylinder 2. At the same time, light will not enter the planting cavity 22, thus restoring the dark environment inside the real soil, thereby ensuring the reliability of the experimental results. When it is necessary to observe the changes in the plant root system in the planting cavity 22 inside the inner cylinder 2 through the outer cylinder 1, the iron plate 36 and the magnet 37 can be separated. Then, turn the handle 39, which drives the drive rod 38 to rotate, and the drive rod 38 drives the rotating rod 33 to rotate. The rotating rod 33 causes the sunshade curtain 34 to wrap around and collect in the collection groove, causing the sliding rod 35 to return to its original position, attracting the iron plate 36 and the magnet 37, thus completing the storage of the sunshade curtain 34.

[0022] The working principle of this utility model is as follows: When in use, plants are planted in the planting cavity 22 of the inner cylinder 2, and then the outer edge 24 of the inner cylinder 2 is attached to the top of the outer cylinder 1. Water is then added to the outer cylinder 1 through the water storage cavity 21 of the inner cylinder 2. The water level is accurately marked by the scale line of the inner cylinder 2. At the same time, in order to prevent the external sunlight from directly shining on the plant roots inside the planting cavity 22, the sunshade curtain 34 of the light-shielding device 3 can be used to block the sunlight from directly shining on the inside of the outer cylinder 1, which can restore the dark environment inside the real soil, thereby ensuring the reliability of the experimental results.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
