Bream farming and processing technology

Also known as Tianlong and Baidu worm, it is a common traditional Chinese herbal medicine that is used to treat convulsions, tetanus, swollen poisonous snakes and so on. Habits are afraid of daylight, and they are nocturnal. During the day, it usually inhabits hillsides, fields, roadsides or overgrown areas. It particularly likes to hide in abandoned gullies, deserted grave packs, gaps in roadsides, rocks, and rubble. From the Mang species to the summer solstice, as the temperature gradually rises, the cricket prefers to live in places that are dark, moist, warm, sheltered from the rain, and air circulated. In the late fall season, they live in leeward sunny slopes or in tree holes. When the temperature is lower than l00°C, it will stop feeding, and it will enter hibernation at minus 7°C. The hibernating baboons are no longer active and do not eat. The body is in an "S" shape. The antennae curl from the outside to the inside and the tails are close together. The depth of latent wintering is directly related to the temperature and the temperature of the soil.蜈蚣 From egg hatching, larval development to adulthood, it takes several times to molt. Once each time, the skin is obviously growing up once. Adults lick their skin once a year and individual lice twice. Do not disturb the skin when it is molted, otherwise it will prolong the molting time (usually about 2 hours). At this time, it is also necessary to prevent the hordes of ants from attacking because the crickets in the pelt have no resistance. The larvae grow slowly, from the first year of egg hatching to larvae, to 3 cm to 4 cm before the hibernation of the year, to 3.5 cm to 6 cm in the second year, and to more than 10 cm in the third year. Therefore, it takes 3 to 4 years for quail to grow from egg to adult and then to lay eggs. Artificial pools can be built in tanks or tanks. Using cylinder culture, use worn-out tile cylinder or ceramic cylinder, the diameter of the narrowest point is above 0.5m, buried about 20cm into the mouth, the middle of the cylinder is made of tattered brick or adobe, about 10cm lower than the cylinder surface, the middle of the cylinder The billet and the cylinder wall have a certain gap. If you use a complete cylinder, do not knock out the bottom, directly in the cylinder can be placed in clay. A cylinder with a diameter of 80cm can be placed around 200 or so. When the pool is raised, the aquaculture pond shall be built in a place with sunny ventilation, good drainage conditions and a relatively humid and secluded place. It may be built indoors or outdoors. Bricks or stones, etc., cement plaster surface, height 80cm, aquaculture pond size random, generally 5m2 ~ 10m2. Fine stones or broken tiles are laid on the ground. Weeds and trees can also be planted in the ponds to create a natural ecological environment suitable for habitats. All around the pool wall with a smooth non-destructive plastic film paste or around the pool with glass around a circle of about 15cm wide and with the pool wall at right angles to prevent the cockroaches escape, but also can prevent harmful animals into the pool. Generally, about 500 to 900 adult larvae can be stocked in aquaculture ponds per square meter. The life span of mating and laying eggs is only 6 years. After sexual maturity, mating is generally conducted in the early morning after the rain in March to May and July to August, and spawning starts in 40 days. Before spawning, the abdomen is almost close to the ground and dug wells. At the time of spawning, the body's body curves into an "S" shape, and the next few steps hold up. The tail foot is upturned and the antennae stretch forward, and then the string of eggs is discharged from the genital hole. The spawning process takes about 3 hours. Each time they spawn 80 to 150 grains, the eggs have mucus on the surface. The eggs stick together and form an egg mass. During the hatching period, the females will not eat or drink until they hatch. After the spawning was completed, the mandarin then skillfully turned the body, gathered the eggs into a group with stepping feet, and hung in his arms. The hatching time was 43 days to 50 days. The quail eggs are oval, of different sizes, beige and translucent. The eggs hatched slowly, with no significant changes in the first 5 days. After 10 days, the eggs became long and flat; after half a month, the eggs became kidney-shaped and the middle marks broke; after 20 days, they became crescent-shaped; after 1 month The larvae form, and in the mother's armpit wriggled; 35 days to 40 days later, the larval body has crawled up and down; from 43 days to 45 days later, the larvae detached from the mother and acted alone, feeding themselves. Dietary fleas belong to carnivorous animals and prefer to eat small insects. Scorpions have venom and can kill smaller animals than themselves. The small animals to be eaten include Tenebrio, tadpoles, rice worms, chafers, termites, cockroaches, cockroaches, spiders, flies, bees, and their eggs, cockroaches, larvae, and the like. You can also feed some worms, cockroaches, snails and all kinds of livestock and poultry, aquatic animal meat, internal organs, blood, cartilage, etc., also eat fruit skins, potatoes, carrots, tender vegetables, etc. Others such as milk, bread, etc., but to ensure food fresh. Management 1. Keep a quiet environment: 蜈蚣 Spawning and hatching require a quiet environment. If there is disturbance, the phenomenon of eating eggs and larvae often occurs. In general, the timing of spawning by females is inconsistent. Non-spawning females often interfere with the normal disruption of spawning and hatching, and some also snatch eggs. Therefore, females should be kept separately before spawning, or they can be isolated in glass, bottomless glass, or canned boxes in large breeding ponds. 2. Prenatal strengthening feeding: The quail does not eat or drink during the incubation period, and maintains its activities by consuming its own nutrition. Before spawning, females have a lot of habits of eating and storing nutrition. At this time, the amount of feeding should be increased and the type of food should be adjusted so as to encourage females to eat more and increase the nutrition before hatching. 3. Incubation period management: During the gestation period, there are certain responses to disturbance, vibration, strong light, strong sound and so on. Therefore, the breeding room must choose a quiet, dark place. It is best to install a red light in the room and block the windows with cloth or bamboo curtains to prevent strong light. Incubation tanks in the house should be set in advance. Once spawned, it is easy to not move. Do not move the covered glass piece (pressing sheet) casually, nor use a flashlight. If the humidity in the incubation nest is too small, it will affect the normal development of the embryo, so the incubation tank should be filled with water in a timely manner. When water is added, it should be slowly poured along the cylinder wall so that the inner wall of the hatching nest can be slightly moistened. When the hatching is over, the female body should be promptly removed or the larvae should be reared in a nest due to the fact that there is contention for food and eating small. 4. Attention should be paid to stocking density: Observing the body length and body size of the earthworms must be observed and grouped and kept in separate ponds. At the same time, we must prevent the elk from running away In addition, we must keep the feed clean and hygienic. In particular, foods contaminated with pesticides must not be fed. Observe regularly to prevent natural enemies from entering the culture ponds and remove sick aphids in time. Processing Method Medicinal pots are dry. After being caught, they were scalded with boiling water, and then they were inserted into the head and tail with two sharpened thin bamboo sticks. They were stretched with bamboo elasticity and dried in the sun. After processing, the cocoons are flat and elongated, with a length of 14cm to 16cm, a width of 0.6cm to l.Ocm, and a total of 22 knots.
