Description

Technical Field

[0001] This utility model belongs to the field of plant water consumption experiments, specifically relating to an experimental device for testing the water consumption capacity of plants. Background Technology

[0002] Plant water consumption capacity is a key indicator of vegetation ecological restoration, directly related to the survival ability of vegetation in specific environments and the stability of the ecosystem. In vegetation ecological restoration projects, accurately testing plant water consumption capacity is crucial for rationally planning water resource utilization, selecting suitable vegetation species, and optimizing irrigation strategies. Through experiments on plant water consumption capacity, researchers can gain a deeper understanding of the water requirements of different plants at different growth stages, thus providing important evidence for ensuring the healthy growth of plants throughout their entire life cycle.

[0003] In existing technologies, transpiration meters are commonly used for experiments. However, these experiments require testing on a single plant, with each experiment typically lasting 12-48 hours. For large-scale single-sample experiments, the experimental cycle is lengthy, and maintaining a consistent experimental environment is difficult. Simultaneous testing of multiple plants requires multiple devices, increasing costs. Other devices exist for testing plant water consumption capacity, but these also rely on single plants, resulting in the same limitations: weak parallel experimental capability and low efficiency per experiment. Furthermore, maintaining adequate moisture is crucial during the experiment. Traditional methods involve timed manual watering or gravity-fed irrigation at a fixed rate. Manual watering is cumbersome, and fixed-rate irrigation cannot adjust the water supply rate according to the different water consumption characteristics of each plant, leading to inaccurate results. Moreover, most existing devices do not effectively distinguish between plant water consumption and soil water absorption, often resulting in inaccurate results. Differentiating between the two requires additional control experiments for data correction, further increasing the experimental steps and overall time. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an experimental device for testing the water consumption capacity of plants, thereby addressing the issues in the prior art. The technical solution adopted by this utility model is as follows: An experimental apparatus for testing the water consumption capacity of plants includes a water storage tank, a grid cylinder, a support container, a buoyancy disk, and a buoyancy adjustment rod; The buoyancy disk is fixedly connected to a plurality of the carrying containers. The carrying containers are provided with an opening for placing the grid cylinder. The grid cylinder is used to place planting soil and a single plant. The bottom of the carrying containers is provided with a water inlet. The water storage tank contains water, the buoyancy plate and the bearing container float on the water surface, and the water enters the planting soil of the grid cylinder through the water inlet; The buoyancy adjustment rod is connected to the buoyancy disk and is used to adjust the buoyancy of the buoyancy disk.

Detailed Implementation

[0013] The following will refer to the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0014] like Figures 1-3 An experimental device for testing the water consumption capacity of plants includes a water storage tank 1, a grid cylinder 4, a support container 5, a buoyancy disk 6, and a buoyancy adjustment rod 7. The buoyancy disk 6 is fixedly connected to a plurality of the carrying containers 5. The carrying containers 5 are provided with an opening for placing the grid cylinder 4. The grid cylinder 4 is used to place planting soil 13 and a single plant. The bottom of the carrying containers 5 is provided with a water inlet 501. The water storage tank 1 contains water 3, the buoyancy plate 6 and the bearing container 5 float on the water surface, and the water 3 enters the planting soil 13 of the grid cylinder 4 through the water inlet 501. The buoyancy adjustment rod 7 is connected to the buoyancy disk 6 and is used to adjust the buoyancy of the buoyancy disk 6.

[0015] Before the experiment, planting soil 13 was filled into multiple grid cylinders 4, and then a single plant to be tested was transplanted into each grid cylinder 4. A certain amount of water 3 was injected into the water storage tank 1 to the initial water level, and the grid cylinders 4 containing the plants were placed into the openings of the carrying container 5. The buoyancy plate 6 and the carrying container 5 were placed into the water storage tank 1 as a whole, so that they floated on the surface of the water 3, with the water level of the water 3 higher than the bottom of the carrying container 5. The water 3 seeped into the planting soil 13 through the water inlet 501 to provide water for the plants. According to the plant type and soil moisture requirements, the buoyancy of the buoyancy plate 6 was adjusted by the buoyancy adjustment rod 7 to keep the carrying container 5 at a suitable suspension height. After standing for a preset time, such as 24-48 hours, the water level changes were observed to obtain the total water consumption of the plants and soil. Then, the soil without plants was tested separately to obtain the soil water consumption. By subtracting the soil water consumption from the total water consumption and then averaging the results, the water consumption capacity of a single plant could be obtained.

[0016] The water body 3 can be pure water or a plant culture solution containing certain nutrients, depending on the growth needs of different plants. The purpose of the adjustable buoyancy of the buoyancy plate 6 is to enable the supporting container 5 to adapt to the root growth needs of different plants and the water absorption characteristics of different soils. The buoyancy of the buoyancy plate 6 is used to regulate the water pressure and the amount of water soaked into the planting soil 13, ensuring that the water can penetrate into the planting soil at an appropriate rate. For example, for plants with well-developed root systems and strong water absorption capacity, such as trees, sunflowers, and sugarcane, the supporting container 5 can be allowed to sink slightly to increase water pressure, accelerate water penetration, and ensure that the plants have sufficient water.

[0017] This invention enables simultaneous experiments on multiple plants, eliminating the need for multiple individual experiments and significantly shortening the overall experimental time; automatic water replenishment avoids frequent manual watering; buoyancy adjustment adapts to different plant and soil weights, ensuring consistent experimental conditions; and the water pressure and soil immersion volume can be adjusted by the sinking height of the buoyancy plate 6 to suit plants with different water consumption capacities.

[0018] It should be noted that plants at different growth stages consume different amounts of water. When conducting experiments, multiple plants at the same growth stage with similar root development and leaf growth should be selected.

[0019] Furthermore, a measuring tube 10 is connected to the side of the water storage tank 1, a float 11 is installed inside the measuring tube 10, and corresponding scale lines are provided on the measuring tube 10.

[0020] At the beginning of the experiment, the reading of the scale line corresponding to the float 11 in the measuring tube 10 was recorded; after the experiment, the reading of the scale line corresponding to the float 11 was recorded again; the reduction of water body 3 in the water storage tank 1 was calculated by the difference between the two readings, that is, the sum of the water consumption of multiple plants and the water absorption of the soil.

[0021] Furthermore, the top of the water storage tank 1 is detachably connected to the outer shell 2, and a plant grow light 12 is installed on the top of the outer shell 2. The plant grow light 12 is existing technology, simulating the natural light conditions for plant growth and avoiding differences in water consumption caused by uneven natural light. In addition, a heating device can be added as needed to regulate the temperature, and a ventilation device can be added to simulate natural wind.

[0022] Furthermore, an annular mesh 141 is provided inside the opening of the carrying container 5, and an annular cavity is formed between the mesh 141 and the inner wall of the opening. The annular cavity is filled with a side absorbent filler 14. A bottom absorbent filler 15 is provided at the bottom of the opening and inside the mesh 141. The bottom absorbent filler 15 contacts the bottom of the mesh cylinder 4, and the side absorbent filler 14 surrounds and contacts the circumferential surface of the mesh cylinder 4. The water inlet 501 is located below the bottom absorbent filler 15.

[0023] The bottom absorbent filler 15 and the side absorbent filler 14 rapidly absorb water through capillary action, creating a uniformly moist environment and ensuring that the planting soil inside the grid cylinder 4 is replenished with water from the bottom and sides. Both the partition net 141 and the grid cylinder 4 are grid structures.

[0024] Furthermore, the side absorbent filler 14 and the bottom absorbent filler 15 are soil, absorbent cotton, or sponge.

[0025] Furthermore, an auxiliary buoyancy body 9 is fixedly connected to the side of the carrying container 5 away from the buoyancy disk 6.

[0026] The auxiliary buoyancy body 9 can be a hollow rubber body with a hollow interior, and scale lines can be set on the auxiliary buoyancy body 9 to reflect the sinking amount of the carrying container 5 and the buoyancy disk 6.

[0027] Furthermore, the buoyancy disk 6 is provided with a downward-facing groove, and a sealing plate 8 is provided in the groove. The sealing plate 8 is connected to the bottom of the buoyancy adjustment rod 7. The buoyancy adjustment rod 7 is threadedly connected to the buoyancy disk 6. The height of the sealing plate 8 is adjusted by adjusting the buoyancy adjustment rod 7 to adjust the buoyancy of the buoyancy disk 6.

[0028] A sealing ring can be installed on the outer ring of the sealing plate 8, and a threaded hole for threaded connection of the buoyancy adjustment rod 7 is provided on the buoyancy disk 6. The change in the height of the sealing plate 8 changes the volume of water displaced by the buoyancy disk 6, thereby adjusting the overall buoyancy.

[0029] The sealing plate 8 and the buoyancy adjustment rod 7 can be a fixed connection or a rotatable connection.

[0030] When conducting experiments with this invention, the following steps can be referred to: Step 1: Divide the planting soil 13 into two parts. One part is evenly distributed in multiple grid cylinders 4, and a single plant is transplanted into the grid cylinder 4. Step 2: Add water 3 to the water storage tank 1 to the initial water level, then place multiple mesh cylinders 4 into the carrying container 5 respectively, and place the carrying container 5 and the buoyancy plate 6 on the water 3 to suspend them. Step 3: Based on the differences in water consumption characteristics of different plants, the height and buoyancy of the buoyancy plate 6 are adjusted by raising and lowering the buoyancy adjustment rod 7, so that the buoyancy plate 6 and the carrying container 5 are at a suitable suspension height. Step 4: Attach the outer casing 2 to the water tank 1 and turn on the plant grow light 12; Step 5: Let it stand for 24-48 hours and record the drop in water level of water body 3 to obtain the total water consumption of plants and water absorption of soil. Step 6: Take out each grid cylinder 4, and then evenly distribute the remaining planting soil 13 (without plants) into the other grid cylinders 4. Step 7, as follows Figure 4 Water is added to the water tank 1 to the initial water level, and then multiple grid cylinders 4 without plants are placed into the corresponding carrying container 5. Finally, the carrying container 5 and the buoyancy plate 6 are placed on the water body 3 and suspended. Step 8: Let it stand for 24-48 hours and record the drop in water level of water body 3 as the amount of water absorbed by the soil. Step 9: Calculate the water consumption capacity of a single plant using the following formula: in, This refers to the water consumption capacity of a single plant. It is the sum of water consumption by plants and water absorption by soil. This refers to soil water absorption. The number of grid cylinders 4 and the supporting containers 5, i.e., the number of plants. The experimental time.

[0031] This invention uses a control experiment to eliminate the influence of soil water absorption by measuring the difference in water level drop between groups with and without plants, thereby obtaining the actual water consumption of the plants. The average value of the water consumption of multiple groups of plants is then used to obtain the water consumption capacity value of a single plant.
