Description

Technical Field

[0001] This utility model belongs to the field of ecological restoration technology, specifically relating to a device for the artificial cultivation and propagation of biological crusts. Background Technology

[0002] Biocrusts are a composite layer formed on the soil surface in arid and semi-arid regions by microorganisms, cryptogams, and related secretions. They can cover and protect exposed soil like "skin." The harsh environment in arid regions (such as water shortage and large temperature differences) leads to slow growth of microorganisms, and the natural succession cycle of biocrusts far exceeds the time requirements of ecological restoration projects. If natural restoration is relied upon, desertification and soil degradation will continue to worsen. Moreover, once biocrusts in the wild are damaged by human activities (such as trampling, engineering construction) or extreme weather, it will take hundreds of years to recover. Artificial propagation can specifically replenish the crust in damaged areas, preventing further degradation of the ecosystem, while reducing dependence on the exploitation of natural crust and protecting native ecological resources; Existing incubators typically have individual temperature and humidity controllers for the artificial cultivation and propagation of biological crusts. However, these controllers cannot monitor and adjust the temperature and humidity of each tray, resulting in uniform temperature and humidity of plant samples within the incubator. Furthermore, excessive moisture in the trays can lead to problems such as microbial decay, which in turn can cause water accumulation and damage to the biological crusts. Utility Model Content

[0003] The purpose of this invention is to provide a device for the artificial cultivation and propagation of biological crusts, which aims to solve the problems in the existing incubators for the artificial cultivation and propagation of biological crusts. These incubators are generally equipped with a single temperature and humidity controller, but they cannot monitor and adjust the temperature and humidity of each tray. This results in the uniformity of temperature and humidity of plant samples in the incubator, and excessive moisture in the trays can lead to microbial decay and damage to the biological crusts.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a biological crust artificial culture and propagation device, comprising a culture box body, a fixing frame welded to the inner wall surface of the culture box body, a partition plate inserted into the inner wall surface of the fixing frame, a water-permeable tray sleeved on the inner wall surface of the partition plate, a culture tray abutting its top surface, a culture tray sleeved in a rectangular groove at the top of the partition plate, a rectangular groove formed on the surface of the culture tray, a limiting strip connected to the surface where the culture tray and the rectangular groove intersect, a baffle plate slidably inserted into the surface of the limiting strip, a drain hole abutting its top surface, a drain hole formed at the bottom transverse end surface of the culture tray, a cotton strip abutting its top surface, a rubber clip connected to the surface of the cotton strip, the rubber clip engaging in a slot formed at the top of a water storage tank, and the bottom surface of the water storage tank connected to the top surface of the culture tray.

[0005] In a preferred embodiment of the biological crust artificial culture and propagation device of this utility model, the shielding plate is a rectangular plate whose shape and size are adapted to the rectangular groove.

[0006] As a preferred embodiment of the biological crust artificial culture and propagation device of this utility model, the shielding plate is provided with symmetrical "T"-shaped through grooves on both sides, and the shape and size of the "T"-shaped through grooves are adapted to the limiting strip.

[0007] As a preferred embodiment of the biological crust artificial culture and propagation device of this utility model, the fixing frame is a U-shaped integrated structure, and the shape and size of the rectangular cavity opened on its surface are adapted to the partition plate.

[0008] In a preferred embodiment of the biological crust artificial culture and propagation device of this utility model, the drainage hole is a circular through groove, and the drainage holes are equally spaced on the bottom surface of the culture tray.

[0009] As a preferred embodiment of the biological crust artificial culture and propagation device of this utility model, the slot is a "U"-shaped groove, the shape and size of which are adapted to the cylindrical middle section of the rubber card head.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The permeable tray embedded in the partition plate allows excess water on the culture tray to drain through the drainage holes into the permeable tray. The permeable tray can catch the excess water seeping out of the drainage holes immediately, keeping the substrate in the culture tray in an ideal state of "moist but not waterlogged". At the same time, it avoids cross-contamination between different culture trays due to water accumulation. In addition, by using the water tank and cotton swabs together, the cotton swabs can slowly transport the water in the water tank to the medium on the culture tray, realizing the function of automatic water replenishment, maintaining the humidity of the culture medium, reducing the frequency and workload of manual water replenishment, and by blocking or opening the holes of the baffle plate at the bottom of the culture tray, the air circulation in the culture tray can be controlled, thereby regulating the humidity.
