The invention discloses a method for cultivating plant-growing concrete seedlings of red sea olive, which comprises the following steps of: fixing seeds of red sea olive in a plant-growing concrete seedling-growing tube, and then directly and vertically planting the plant-growing concrete seedling-growing tube on a field mud flat wetland for natural seedling cultivation. The vegetation concrete seedling raising pipe is formed by pouring seed germination concrete on the upper layer and seedling breeding concrete on the lower layer in the seedling raising pipe in a laminated mode. Wherein the seed germination concrete and the seedling breeding concrete are prepared from sea mud, sea sand, cement, seawater and fertilizer according to different dosage ratios. According to the method, the three functions of seed germination, seedling breeding and field planting application can be achieved in the same device, and the cultivation rate, the survival rate and the retention rate of the natural seedlings of the red sea olive can be remarkably increased.

The invention discloses a pure kelp powder extruded puffed food and a preparation method thereof, and belongs to the field of food processing. The method comprises the following steps: (1) drying kelp, crushing, and sieving to obtain kelp powder; (2) extruding and puffing the kelp raw material powder by using a twin-screw extruder, and setting the extrusion temperature of each area of the twin-screw extruder, the kelp powder feeding amount, the water inlet amount and the screw rotating speed; and (3) finally, collecting a product obtained in the step (2), and finishing and forming after the product is cooled. The kelp powder is used as the raw material, and no grease is added, so that the prepared puffed food is low in calorie, rich in various components such as dietary fibers, high in nutritional value and balanced in nutrition; through a twin-screw extrusion technology, the raw materials are puffed in a high-temperature and high-pressure state, caramelization and Maillard reaction of the materials are promoted, insoluble dietary fibers are converted into soluble dietary fibers, and the product is endowed with unique flavor and crisp taste.

The invention discloses a circular economical laying hen feed formula and a processing preparation method, and belongs to the technical field of livestock and poultry feeds, the formula comprises yellow mealworm sand, rumex hanus, chicory, sweet sorghum grains, sweet potatoes, wormcast, yellow mealworm powder, shell powder, stone powder, peanut oil, a premix and peanut cakes, and the proportion of unconventional raw materials exceeds 70%; according to the processing and preparation method, through multiple processes of anaerobic aerobic fermentation, oyster mushroom strain decomposition, curing, air drying and the like, toxic and harmful ingredients in the raw materials are degraded, the nutrition structure is optimized, and meanwhile a circulating closed loop of planting, edible mushroom, earthworms, tenebrio molitor and laying hen breeding is constructed. The feed is balanced in formula nutrition, all core nutrition indexes are matched with the suitable range of laying hens in the egg producing period, and the feed is good in palatability and can be directly used for feeding the laying hens in the egg producing period; agricultural waste resource utilization is achieved, ecological and economic benefits are remarkable, and the method has extremely high industrialization value and popularization prospects.

This invention belongs to the field of turfgrass and forage grass maintenance technology, specifically relating to a microbial selenium protein preparation for alleviating drought stress in perennial ryegrass, its preparation method, application method, and application. The microbial selenium protein preparation comprises the following raw materials in specific weight proportions: peptone, beef extract, sucrose, salt, selenium-enriched mushroom powder, organosilicon, calcium amino acids, potassium humate, betaine, salicylic acid, and Bacillus natto. This microbial selenium protein preparation aims to solve the limitations of traditional drought-resistant methods and the poor effectiveness of single-component preparations. When using this microbial selenium protein preparation, it is first diluted and then applied as a root drench to ryegrass seedlings multiple times. The selenium protein preparation of this invention, through the synergistic effect of multiple components, can significantly improve the drought resistance of ryegrass. Furthermore, the preparation process of this protein preparation is simple, environmentally friendly, and efficient, suitable for ryegrass propagation and maintenance, and has broad application prospects.

The invention provides a peach jelly and a preparation method thereof. The steps include: obtaining peeled peach pieces according to a mold; steaming to kill enzymes; preliminarily freeze-drying to obtain peach pieces in a preliminarily dehydrated state; dipping in a mixed solution of carboxymethyl chitosan and water-soluble dietary fiber obtained by enzymatic extraction; taking out and freeze-drying again to obtain a quasi-freeze-dried peach piece with a macroporous structure; dipping in a low-viscosity konjac gum solution containing milk small bursting beads; taking out and coating, drying and sterilizing to obtain. The invention obtains a peach piece in a preliminarily dehydrated state with a microporous structure, and the fine and dense pores facilitate the entry of carboxymethyl chitosan to strengthen the fiber toughness of the peach piece; the second freeze-drying obtains a quasi-freeze-dried peach piece with a macroporous structure, which is not completely freeze-dried and is convenient for rehydration, but at the same time has formed a stable porous structure, which can facilitate the entry of low-viscosity konjac gum solution and milk small bursting beads to obtain a peach jelly similar to jelly but better than jelly in taste.

The present invention discloses a microalgae composition and its application in bullfrog breeding and promoting the growth and metamorphosis of bullfrog tadpoles. The present invention optimizes the nutritional structure of bullfrog feed by adding a specific microalgae composition, promotes the weight growth and metamorphosis of bullfrogs in the tadpole stage, shortens the time of adult frogs, improves the efficiency and success rate of metamorphosis, reduces reproductive losses, saves feed, reduces feeding costs, and also promotes the development of the digestive system and immune system of bullfrogs, maintains the health of the digestive tract, improves the digestion capacity of feed, and enhances immunity. The present invention not only improves the breeding efficiency of bullfrogs, but also reduces the dependence on chemical additives, is conducive to environmental protection and green sustainable development, and can also promote the wide application of microalgae in aquaculture, bringing new development opportunities to related industries.
