The invention relates to a high-frequency regeneration and rapid propagation method of Enkianthus chinensis tissue culture seedlings. The invention is characterized in that dormant axillary buds of semi-lignified young stems are used as the base. The method comprises the following main steps: sampling and disinfection treatment of explants, inducing of dormant axillary bud germination, inducing of adventitious bud and lateral bud high-frequency generation, strong seedling culture, test-tube rooting culture and acclimatization and transplanting. Finally, regenerative plants which have consistent parental character, excellent quality and strong stress resistance are obtained. According to the invention, lots of seedlings with consistent specification and excellent quality can be obtained within a short period of time, and marketization progress of Enkianthus chinensis is promoted powerfully.

The invention relates to a grouper crossbreeding method. The method comprises the four steps of parent breeding, temperature-sensitive domestication, artificial spawning and insemination, incubation and fry breeding, specifically, cold water-based clear water stone spots and hot water-based brown spot stone spots are selected as parents, the clear water stone spots are used as female parents, the brown spot stone spots are used as male parents, and the middle water temperature is adapted through gradient temperature-sensitive domestication; stress-resistant feed containing hilsa herring egg source peptide and haematococcus pluvialis astaxanthin ester and a temperature-sensitive blender are matched, a reproductive care agent is supplemented to strengthen sperm and egg performance, and normative spawning induction, insemination and graded cultivation processes are adopted. According to the method, the problems of poor water temperature adaptation and low hatching rate of grouper hybrid sperms and eggs in different temperature areas are solved, the wide-temperature property of filial generations is improved, the method adapts to the water temperature of 18-28 DEG C, the hatching rate, the fry survival rate, the adult fish survival rate and the average weight of single fish are remarkably improved, and technical support is provided for industrial application.

This application relates to an ecological restoration system and method suitable for high-altitude and cold environments, specifically in the field of environmental restoration systems. The system includes: leveling a surface to create a smooth surface on exposed surfaces in high-altitude and cold environments; constructing an acclimatization shed on one side of the leveled surface, where acclimatized plants are planted; laying a base mesh layer on the leveled surface, with multiple fixing devices on the base mesh layer to secure it to the leveled surface; spraying topsoil onto the base mesh layer to form a restoration substrate layer; pressing planting troughs into the surface of the restoration substrate layer and transplanting the acclimatized plants from the acclimatization shed into the planting troughs; covering the surface of the restoration substrate layer with a protective layer; installing miniature meteorological and soil moisture monitoring equipment on the restoration substrate layer, the miniature meteorological and soil moisture monitoring equipment having an alarm function; and also installing drip irrigation equipment on the restoration substrate layer. This application has the effect of optimizing the restoration effect of high-altitude and cold environment restoration work.

A system of estimating acclimatization to environmental conditions and providing a corrected fitness level estimates based on the acclimatization level. The environmental conditions are particularly related to heat and altitude. At first previous training history is provided including a plurality of day records, where each day record includes a date stamp and information regarding altitude and optionally temperature and humidity and training history including timestamp and training load data from executed exercises in stored records.

The invention relates to the technical field of biomedicine and nutriology, and relates to a composition for targeted inhibition of lipid peroxidation to promote plateau study and application. Specifically, protein change characteristics of plateau hypoxia stress cells or mouse tissues are analyzed through a proteome technology, a lipid metabolism change rule in the plateau hypoxia stress mouse tissues is analyzed through a targeted lipid metabolome technology, and lipid peroxidation damage of hypoxia to the cells is analyzed through tests such as MDA content determination, ATP content determination and CCK8 cell activity detection. And providing a scheme of jointly supplementing iron and oleic acid to promote plateau exercise, and verifying in animal experiments. The iron and the olive oil are supplemented into the feed at the same time, so that the oxygen partial pressure and the oxyhemoglobin saturation of the mouse can be further improved while the mouse resists lipid peroxidation damage caused by high altitude hypoxia. The combined supplement of iron and olive oil can reduce tissue damage and improve the plateau taking ability of the organism, and the method is a safe and effective plateau taking promoting strategy.

This invention provides a method for the low-temperature gradient acclimatization and selection of edible fungi strains. First, the starting strain is rejuvenated, purified, and mononuclearized to obtain a genetically homogeneous initial strain. Then, a multi-level arithmetic gradient low-temperature stress system is constructed. Through gradient cooling and multiple generations of continuous low-temperature stress culture, combined with mycelial vigor and stress-resistance morphology, a two-dimensional initial screening is completed generation by generation. After verifying and eliminating unstable strains through alternating high and low temperature stress cycles, physiological and biochemical detection and molecular marker-assisted identification are integrated to screen genetically stable low-temperature tolerant strains. Finally, agronomic traits are comprehensively evaluated through low-temperature fruiting cultivation experiments, ultimately selecting excellent low-temperature tolerant strains with strong stress resistance and stable heritability. This low-temperature gradient acclimatization and selection method solves the problems of unstable traits, easy reversion, and poor cultivation adaptability associated with traditional low-temperature acclimatization. The acclimatization process is standardized and coherent, with high selection accuracy, and is suitable for the improvement of low-temperature stress-resistant germplasm and off-season cultivation of various edible fungi.

A method for breeding redclaw crayfish in extremely cold soda-saline-alkali areas belongs to the field of freshwater crayfish artificial breeding technology. To address the problem of inconsistent environmental conditions for overwintering, hatching, and juvenile rearing of redclaw crayfish in extremely cold soda-saline-alkali environments, this invention employs a three-tiered gradient of carbonate alkalinity pre-acclimatization, a three-zone integrated extremely cold-insulated breeding greenhouse configuration, low-temperature overwintering within the greenhouse, stepped temperature increases to promote maturation, independent sealed compartments for mating and hatching, and segmented juvenile rearing. This method ensures that different breeding stages are matched with corresponding temperature, water quality, and circulation conditions, reducing the impact of extreme low temperatures and soda-saline-alkali water quality fluctuations on the continuous breeding process. It is applicable to freshwater crayfish artificial breeding, redclaw crayfish breeding in extremely cold regions, and juvenile redclaw crayfish cultivation in soda-saline-alkali waters.
