Pear Fruit Storage and Fresh-Keeping Methods and Technical Key Points
Different pear varieties and types require different optimal temperature, humidity and optimal gas composition standards. For newly bred varieties, experiments must be conducted to determine the suitable temperature, humidity and optimal gas composition required for their storage, so that temperature and humidity control and gas composition regulation can be effectively carried out during storage to achieve the best storage results. Pear fruits are broadly divided into two major types. 1. Crisp-fleshed type varieties: The white pear system and the sand pear system mostly belong to the crisp-fleshed type. Generally, crisp-fleshed varieties, after harvest

How to detect suspicious sick rabbits early? A must-read for rabbit keepers
Examine the ear color of a healthy rabbit: pink, with bright eyes. If the ears are red or light purple, it means the rabbit is overheated; placing it in a ventilated hutch to rest a while will relieve it. If the ears are pale and feel cool to the touch, it means the rabbit has drunk too much cold water or has caught a chill; on auscultation there will be a sloshing sound in the abdominal cavity, and placing the sick rabbit on a heated kang to warm its belly will suffice. If a young rabbit's ear tips bend forward or droop slightly, it means its body temperature is high; let it move about freely for a while to help bring the temperature down. If a rabbit's eyeballs look dull, it indicates the air in the hutch is foul, and ventilation should be carried out promptly. A rabbit running clear watery nasal discharge is a precursor of common cold,

What are the precautions for feeding pigs with distillers' grains? Farmers should keep them in mind
Distillers' grains are divided into baijiu distillers' grains and beer distillers' grains. Baijiu distillers' grains have 32 percent dry matter, 3.36 MJ per kg digestible energy, and 7.5 percent crude protein. Beer distillers' grains have 14 percent dry matter, 1.43 MJ per kg digestible energy, and 3.6 percent crude protein. Whether baijiu distillers' grains or beer distillers' grains, they must be fed fresh; if piled up for a long time, they will become moldy and spoiled. If there is any left over, it can be put into a large vat, trampled down firmly, and soaked in water. Pregnant sows and lactating sows are not suitable for feeding, to prevent miscarriage, stillbirth, and so on. For meat pigs, it generally does not exceed the daily ration

Releasing fish fry in early spring requires care; keep these precautions in mind
Fish fry quality For fish fry of the same species and same age, the specifications should be uniform, with little difference in body length and body weight, thick back muscles, bright color, intact scales and fin rays, normal activity, and strong upstream-swimming ability. After being taken out of the water and placed in a basin, the gill covers should not open, the tail should not bend, and the fish should keep jumping, with no wounds or parasites on the body surface. Fish fry disinfection Some farmers do not disinfect fish fry at all when releasing them, resulting in a high disease rate, and drug treatment is not ideal. In fact, as long as fish fry disinfection is done well, disease prevention can often achieve twice the result with half the effort

How to keep the cardinal tetra? Care methods and precautions
Native to the middle and lower reaches of the Amazon River. The fish body is 4 cm to 5 cm long, spindle-shaped, and laterally compressed. The body is slightly wider than that of the neon tetra. The dorsal and ventral margins form a shallow arc, and the head and caudal peduncle are correspondingly wider, with a rounded, blunt snout tip. The mouth is slightly large, and the eyes are also large, located at the upper front of the head. The dorsal and pectoral fins are normal in shape, and the distance from the origin of the dorsal fin to the snout tip is slightly shorter than the distance to the base of the caudal fin. The anal fin is elongated, and the caudal fin is forked. The body color is very brilliant, with a yellow-green appearance on the back. The striking feature of this fish is on both sides: from the rear edge of the eye to the caudal peduncle there is a relatively wide blue longitudinal band, and below the longitudinal band there is

What are the correct methods for storing honey to keep it fresh?
Honey is rich in nutrients and health-promoting properties, and has a sweet, fragrant taste. However, because honey is a liquid substance, with all its components coexisting in an aqueous solution, quality problems can arise if it is stored improperly. If its nutrients or aromatic substances are lost, its nutritional value and health benefits will be reduced, and its taste will deteriorate, so keeping honey fresh is extremely important. The reasons honey quality changes are very complex; under certain conditions, various components may undergo physical and chemical changes. For example, sucrose can decompose

There's a right way to feed rabbits: keep these three dos and three don'ts in mind
Feed a complete mixed ration. The nutrient composition of a rabbit's daily ration is: 10% crude protein and 10% crude fiber, 5% fat, 2800 kcal of digestible energy per kilogram of ration, and 10% amino acids. If there is no way to feed a complete mixed feed, appropriately add concentrated feeds such as soybeans, soybean cake, wheat bran and corn, along with succulent feeds such as carrots. Feed heavily at night. Rabbits have a strong tendency to eat at night, and nighttime intake can account for more than 75% of their total daily intake. Therefore, provide rabbits with enough feed and drinking water at night. Change feed gradually. When one kind of feed has been fed for a long time, the rabbit has

How Beekeepers Observe Bees Outside the Hive to Judge Conditions Inside
Honeybees are social insects that prefer a stable, quiet environment. In artificial beekeeping, opening the hive to inspect the bees is unavoidable due to production needs. But if the hive is opened too often and too frequently, it will inevitably disturb the colony's stability, and may even cause the colony to refuse the "climate" and abscond as a whole. Under normal temperature conditions, several bees stand at the hive entrance, not biting the entrance, not vibrating their wings, not crawling over one another, only paying a little "attention" to bees going in and out, or slightly following them; worker bees enter and exit one after another in succession; returning bees are either big-bellied, or have pollen pellets stuck to two legs.

Harvesting and Fresh-keeping Methods for Cuttings of Amorpha fruticosa, an Open-field Flower
[Other Chinese names] Mianhuai [Family and genus] Fabaceae, Amorpha [Place of origin] North America [Plant characteristics] Amorpha fruticosa is a clumping shrub. Plant height 1-4 m. Branches grayish blue. Odd-pinnate compound leaves alternate; leaflets 11-25, oblong. [Cutting harvest] The harvested part is the first-year woody branch of Amorpha fruticosa, preferably 1-1.5 cm in diameter. To obtain the ideal propagation results, top branches with shorter internodes and full growth should be selected. Pay attention to reasonable cutting collection so as not to affect
