Description

Technical Field

[0001] The utility model belongs to the technical field of plant tissue culture, in particular to a culture rack for tissue culture callus of arbor plants. Background Art

[0002] The North American cedar is a tree belonging to the genus Thuja of the Cupressaceae family, with unique ecological characteristics and wide application value. Because of its strong ability to resist smoke and toxic gases, it can be planted in industrial and mining areas; it can repel parasites, and the cedar oil extracted is also a good raw material for aromatic oil; its wood is soft and resistant to corrosion, and can also be used for electric poles, sleepers, construction, shipbuilding, etc.

[0003] Callus is an amorphous, unorganized mass of thin-walled tissue produced by explant tissues or cells (such as roots, stems, leaves, flowers, fruits, seeds, etc.) under specific culture conditions during plant tissue culture. When cedar callus is cultured, the callus is generally placed in a culture container on a culture rack for growth. However, it is difficult for existing cedar callus culture racks to reasonably set the interlayer spacing of the culture rack based on the growth requirements of the callus and the scale of the experiment. Too large an interlayer spacing leads to low space utilization, and too small an interlayer spacing affects ventilation and lighting conditions. Even if some culture racks can adjust the interlayer spacing, it is difficult to control the closedness after adjustment, resulting in inconvenient temperature and humidity control between layers, increased pollution risk, and easy invasion of external pollutants, such as bacteria, fungi and other microorganisms, which increases the risk of pollution in the culture environment and affects the health and growth effect of the callus. In addition, the culture container of the existing cedar callus culture rack is not convenient to take and put, the functionality is relatively single, and there is a lack of effective display and comparison function, which cannot clearly display the comparison between different treatments or different samples.

[0004] Therefore, we provide a culture rack for tissue culture callus of arbor plants to solve the above problems. Summary of the invention

It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Embodiment 1

[0027] To solve the problem that the closedness of the existing North American cedar callus culture rack is difficult to control after the layer spacing is adjusted, resulting in inconvenient temperature and humidity control between layers and increased pollution risks, please refer to Figure 1-Figure 4 The utility model provides a culture rack for tissue culture callus of arbor plants, comprising a base 1 and a plurality of stacked frame units 2 located above the base 1, the frame unit 2 comprising a bottom plate 201 and a placement slot 202 slidably arranged on the top of the bottom plate 201 for placing a cedar callus culture container, and a foldable closing component 203 is provided at the bottom of the bottom plate 201. When the interlayer spacing between the bottom plates 201 and 201 is adjusted, the closing component 203 covers the internal space as a whole, reduces the risk of contamination, and prevents the cedar callus from being invaded by external pollutants.

[0028] The docking surfaces between the base 1 and the frame unit 2 and between adjacent frame units 2 are fixed by means of a plug-in structure, which includes a column 201d, an insertion rod 201f located on one end face of the column 201d, and a slot plugged with the insertion rod 201f; a support plate 201c movably sleeved on the column 201d and fixed on the side face of the bottom plate 201, and a second knob 201e for locking the support plate 201c for lifting and lowering is provided on the side face of the support plate 201c.

[0029] Based on actual needs, stack a suitable number of frame units 2; then adjust the spacing between adjacent bottom plates 201 based on the growth requirements of the American cedar callus and the scale of the experiment. When adjusting, loosen the second knob 201e, and the support plate 201c can move freely along the column 201d. The support plate 201c drives the bottom plate 201 to move to the required height, and then tighten the second knob 201e. The interlayer spacing of the culture rack can be reasonably set to avoid low space utilization due to excessive interlayer spacing and ventilation and lighting conditions affected by too small interlayer spacing.

[0030] A limiting structure for limiting the position of the culture container is provided on the inner top surface of the placement slot 202 and the top surface of the base 1, and the limiting structure includes a magnetic attraction plate 202b embedded in the plate body and a magnetic buckle 202c adsorbed on the magnetic attraction plate 202b; the closed component 203 includes a fixed plate 203a fixed at the bottom of the base plate 201, a folding cover 203b fixed at the bottom of the fixed plate 203a, and a magnet ring 203c fixed at the bottom of the folding cover 203b; four vertical plates 203d distributed in a matrix are also fixed at the bottom of the fixed plate 203a, and a magnet bar 203e is fixed at the bottom of the vertical plate 203d; when the closed component 203 is in the unfolded state, the magnet ring 203c is attracted to the magnetic attraction plate 202b below it, and when the closed component 203 is in the folded state, the magnet ring 203c is attracted to the magnet bar 203e on its side.

[0031] When the interlayer spacing is adjusted, pull the magnet ring 203c downwards, and the magnet ring 203c is separated from the magnet bar 203e until the magnet ring 203c is adsorbed onto the magnetic suction plate 202b, thereby completely closing the entire interlayer space through the folding cover 203b, making it more convenient to control the temperature and humidity in the space, effectively reducing the risk of pollution, and avoiding the invasion of external pollutants, such as bacteria, fungi and other microorganisms, thereby improving the health and growth effect of the North American cedar callus.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, in order to improve the convenience of taking and placing the culture container and improve the functionality of the entire culture rack, as Figure 3 As shown, a first knob 202a for locking the sliding of the placement slot 202 is rotatably provided on the side surface of the end of the placement slot 202 away from the human body, and a slot hole 201a matching the first knob 202a is provided on the side surface of the bottom plate 201; an inclined portion 201b for supporting the placement slot 202 in an inclined state is provided on the side of the bottom plate 201 close to the human body.

[0034] When it is necessary to take and place the cedar callus culture container in the placement slot 202, loosen the first knob 202a and pull the placement slot 202 outward. At this time, the first knob 202a moves along the slot 201a. When the placement slot 202 moves to the outermost end, due to the setting of the inclined portion 201b, it loses support and becomes tilted. At this time, the cedar callus culture container in the placement slot 202 is completely exposed, so it is convenient to take and place. At this time, the placement slot 202 can be used as a comparison component. When different samples need to be compared, the corresponding sample is placed in the placement slot 202 and positioned by the magnetic buckle 202c. The tilted state makes it convenient for experimenters to clearly display the comparison between different cedar samples.

[0035] Embodiment 3

[0036] On the basis of the first and second embodiments, in order to further improve the functionality of the culture rack and enable the lighting assembly 204 to adapt to the use of different layer spacings, such as Figure 2 , Figure 5 As shown, a height-adjustable lighting assembly 204 is also provided at the bottom of the base plate 201, and the lighting assembly 204 is located in the closed assembly 203; the lighting assembly 204 includes a mounting plate 204a for mounting lighting fixtures and a lifting structure located above the mounting plate 204a for pulling the mounting plate 204a to move; the lifting structure includes a toothed belt 204b fixed at one end to the top of the mounting plate 204a and a gear 204c matching the toothed belt 204b, the other end of the toothed belt 204b is located in a slide groove in the bottom inner cavity of the base plate 201, a bearing seat 204d is also fixed in the bottom inner cavity of the base plate 201, the rotating shaft of the gear 204c is rotatably connected to the bearing seat 204d, a nut 204e for locking the rotating shaft is sleeved on the rotating shaft of the gear 204c, and a turntable 204f is fixed at the end of the rotating shaft of the gear 204c.

[0037] When the height of the mounting plate 204a needs to be adjusted to meet the requirements of different North American cedar callus tissues and layer spacings, the nut 204e is loosened, and the shaft of the gear 204c can rotate freely. The turntable 204f is turned, and the turntable 204f drives the gear 204c to rotate, and the gear 204c drives the toothed belt 204b to move, and the toothed belt 204b drives the mounting plate 204a to move, thereby realizing the adjustment of the height of the lighting fixture.

[0038] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
