This invention discloses an environmental sample preservation box based on phase change material (PCM) temperature control. The box includes a body with an inner liner and a sample holding chamber inside. The outer side of the inner liner is covered by a first PCM cold storage module, and the outer side of the sample holding chamber is covered by a second PCM cold storage module. This invention is applicable to the field of environmental sample preservation technology. It utilizes PCM cold storage for cooling, maintaining a constant temperature without any external power supply. This breaks through the dependence of traditional cold storage boxes on electricity, achieving truly passive operation, and is particularly suitable for field and emergency conditions. By setting two PCM layers with different melting points, it creatively transforms a large external temperature difference into a relatively stable internal temperature difference. The outer PCM module absorbs environmental thermal shock, while the inner PCM module precisely controls the sample temperature, achieving multi-level gradient temperature control. The PCM cold storage materials are integrated in a standard modular form, facilitating filling and replacement. The number of cold storage modules can be freely combined according to different transportation durations to meet different insulation time requirements.

This invention relates to the field of anatomical specimen preservation technology, and more particularly to a method for the long-term preservation of anatomical visceral specimens. The method includes: collecting environmental parameters, visual images, and attribute data of the specimens; generating a monitoring data set after standardization processing; constructing and updating an individual characteristic profile of the specimen based on this data set; performing a fusion analysis on the data set by combining pre-set weights corresponding to organ type and preservation method to generate a comprehensive status assessment result; inputting the data set and assessment result into a pre-constructed hybrid prediction model to output a future status prediction report with confidence scores; inputting the assessment result and prediction report into a pre-constructed hierarchical decision engine to generate personalized preservation and maintenance instructions; and finally, based on these instructions, performing adaptive regulation or triggering early warnings for the specimen preservation environment. This invention achieves individualized and precise assessment and proactive maintenance of specimen status, improving the stability and intelligence level of long-term preservation.

The present application relates to the field of plant preservation technology, and discloses a method for preserving microalgae plants. The present application aims to improve the existing preservation methods for microalgae plants, especially the preservation methods for bait microalgae, in order to solve the problems of short preservation time, loss of nutrients and decreased activity of existing microalgae after preservation. The present application achieves the purpose of extending the preservation time and activity of algae by adding choline chloride to the microalgae preservation method to maintain the balance of carbon and nitrogen sources in the culture medium, and adding nickel salts to promote the activity of algae photosynthetic pigments in the stable period. Compared with the conventional low-light or no-light preservation method combined with low-temperature refrigeration, the microalgae preserved by the method of the present application can be preserved for a longer time under the premise of the same activity, and have higher activity under the premise of the same preservation time, and the activity is several times that of microalgae preserved by conventional methods.

The present invention relates to the technical field of instant preservation of fruit tree resources, and in particular to an instant preservation device and preservation method for fruit tree resources collected in the wild. The tail of a shell is fixedly connected to a flexible telescopic bag, the tail end of the flexible telescopic bag is fixedly connected to a bottom plate, the front end of the shell is provided with a placement opening for branches to enter, and an inlet cap is spirally connected to the placement opening. The shell is provided with a one-way air inlet valve and a one-way air outlet valve, the front end of the shell is provided with a first slide groove, and one side of the shell is rotatably connected to a hinge through a hinge. When the present invention is used, the hinge is first unfolded to enable the first slide groove and the second slide groove to be aligned. When the hardness of the branch is low, the slider is quickly slid, and the blade formed by the inclined part relies on inertia to quickly complete the plane cutting of the branch. After the cut part of the branch is cut, it will be first covered by the slider under the sliding action of the slider, and then quickly covered by the moisturizing block, reducing the occurrence of oxidation while providing a water retention effect.
