Description

Technical Field

[0001] The utility model relates to the technical field of waterlogging depth experiments, and in particular to a plant experimental device with adjustable waterlogging depth and root system visualization for observation. Background Art

[0002] In order to alleviate the dual pressures of climate warming and soil compaction on agricultural production, research on crop waterlogging tolerance will help stress-resistant breeding and reduce agricultural economic losses caused by waterlogging disasters.

[0003] The impact of waterlogging stress on crops varies depending on crop type, variety, growth period and soil environment. How to breed waterlogging-tolerant crop varieties is a difficult problem faced by breeding researchers. The root system is the first plant organ to sense, respond and adapt to waterlogging stress. Its physiological growth activities are inhibited to a greater extent than the aboveground parts. Waterlogging causes the plant roots to be in an oxygen-deficient or even anaerobic state, and root respiration is blocked, thereby affecting root growth and nutrient absorption. After the waterlogging is removed, the roots resume aerobic respiration and resume growth. However, due to differences in root plasticity and their ability to obtain nutrients, there are great differences in the recovery rate and final yield of the aboveground parts among varieties. This makes the identification of root waterlogging tolerance and recovery ability particularly important in variety selection. Observation of root plasticity has become the key to evaluating waterlogging tolerance. However, there are currently few devices for visual observation of roots under waterlogging stress, most of which cannot perform continuous observation and are difficult to adjust the waterlogging depth. Therefore, a plant experimental device for visual observation of roots with adjustable waterlogging depth is urgently needed to overcome the above-mentioned defects. Utility Model Content

[0006] Furthermore, the water supply pipe passes through the left side of the transparent basin and is connected to the top of the right side expansion joint, the slot is opened at the top of the right side of the water supply pipe, and the first corduroy cloth is arranged inside the slot.

[0007] Furthermore, the side pipe is connected to the right side of the transparent basin, and the second corduroy cloth is arranged at the bottom of the inner cavity of the transparent basin.

[0008] Furthermore, the limiting iron frame is fixedly installed on the top of the right side of the transparent basin, and the magnetic attraction ring is arranged on the top of the limiting iron frame.

[0010] Furthermore, the heat insulation layer is arranged on the inner surface of the PVC film base layer, and the thickness of the light shielding layer is greater than the thickness of the heat insulation layer.

[0011] In summary, due to the adoption of the above technology, the beneficial effects of the utility model are:

[0012] The utility model supplies water to the experimental components by arranging a water supply tank, and facilitates the expansion of the experimental components by arranging an expansion joint. At the same time, a large number of plant types and plant varieties can be studied. Water is filled into the water supply tank by arranging a water guide pipe, and the experimental components are shielded from light by arranging an outer cover. Water is conveniently discharged by arranging a drainage component. When in use, multiple groups of experimental components are connected through the expansion joint, and soil is poured into the inner cavity of the transparent basin, and plants are planted. Then, the magnetic suction ring is contacted with the limiting iron frame, so that the side pipe is vertically fixed. After fixation, the staff injects water into the water supply tank through the water guide pipe. Water is then introduced into the soil through the water supply pipe and the first corduroy cloth to maintain the waterlogging depth required for the experiment. At this time, the plant is in a state of waterlogging stress. The limiting iron frame is then disengaged from the magnetic suction ring, and the side pipe is lowered. At the same time, the expansion joint is disconnected from the water supply pipe, and the soil in the transparent pot is drained to allow the plant to resume growth. During the entire process, the plant root system can be observed at any time, which has the advantages of convenient observation and expandable number of experiments, and solves the problem that there are currently few devices for visual observation of the root system under waterlogging stress, most of which cannot perform continuous observation and are difficult to adjust the waterlogging depth.
