The utility model discloses a tilapia mossambica hotbed type overwintering device, which relates to the technical field of aquaculture devices and comprises a warmer and a hotbed. The heater is used for providing hot water into the hotbed; the hotbed is arranged at the bottom of the overwintering pond. The tilapia mossambica hotbed type overwintering device is easy to manufacture and convenient to operate, hot water is provided for the hotbed through the heater, only the water temperature in the hotbed is increased, tilapia mossambica overwinter on the hotbed, hot water in the hotbed does not exchange with pond water in the overwintering pond, and energy is saved by more than 40%.

The invention discloses an alpine region afforestation method, and belongs to the technical field of afforestation, the method comprises the steps of soil pretreatment, nursery stock transplantation, stabilizer application, later-stage management and protection and the like, indigenous tree species nursery stocks are selected in spring for transplantation planting, and then a stabilizer A and a stabilizer B are prepared for application; the stabilizer A continuously reacts to release heat so as to increase the temperature of rhizosphere soil, the stabilizer B inhibits the released heat from dissipating outwards for heat preservation, and the rhizosphere soil is heated and preserved through the combined action of the stabilizer A and the stabilizer B, so that safe overwintering of nursery stocks is guaranteed, and the final afforestation survival rate is increased; the method disclosed by the invention has important significance in promoting the restoration of the ecological environment of the alpine region.

The invention relates to grass carp and black carp overwintering feed and a production method thereof, and belongs to the technical field of fish feed. According to the overwintering feed for the grass carps and the black carps, the food calling performance, the nutrition performance and the functionality of the overwintering feed are greatly improved through winter nutrition adaptation, health-care factor addition and a microbial fermentation technology, physical recovery and physique enhancement of the overwintering fishes are facilitated, and therefore the prevention effect on the overwintering syndromes is achieved; the problems that an existing overwintering feed cannot effectively provide nutrition and energy for overwintering fishes and is not easy to digest and absorb are solved, and the feed is particularly suitable for overwintering feeding of grass carps and black carps.

The invention provides a degradable liquid anti-freezing film and a grape cultivation method for safe overwintering without burying soil, and belongs to the technical field of degradable liquid mulching films. The degradable liquid anti-freezing film is prepared from substances such as humic acid and sodium lignin sulfonate; the cultivation method comprises the following steps: load capacity control: controlling the ear remaining amount of each plant through ear thinning; spraying a kaolin composite particle film on the grape plants; water and fertilizer management: ditching, applying organic fertilizer and irrigating after dormancy in winter; ecological soil management: sowing and managing pasture among rows, and covering crushed branches in the rows; delaying winter pruning before bleeding in spring; and spraying a degradable liquid anti-freezing film on the tree trunk and the field planting belt ground. Through comprehensive management measures, the cold resistance of grape plants is effectively improved, soil-burying-free safe overwintering is achieved, the production cost is reduced, and meanwhile ecological environmental protection is promoted.

The application discloses a gallnut dwarfing and dense planting and precise layering inoculation method, which comprises five steps of dwarfing seedling cultivation of rhus copallinum, dwarfing and dense planting, soilless cultivation of winter host moss and overwintering and nursing of aphid, precise layering inoculation of aphid, field management and harvesting. A high adaptability rhus copallinum source is screened, dwarfing and dense planting is realized through multi-effect azole regulation, the soilless moss bed substrate is optimized to cultivate moss, 11000-13000 aphids are inoculated per square meter and temperature and humidity are controlled to overwinter, in spring, precise inoculation is carried out according to the three-layer structure of the rhus copallinum crown layer, matching different specifications of moss blocks, inoculation densities and components, water and fertilizer management and green prevention and control are combined with the period of insect galls, and natural airing and harvesting are carried out. The application constructs a collaborative planting system, is simple and convenient to operate, low in cost, improves the survival rate and the aphid knotting rate of aphid, realizes waste recycling, is suitable for large-scale and intensive planting, and significantly improves the yield and quality of gallnut.
