Two Technical Points of Breeding Earthen

(1) feeding equipment may be developed according to the size and purpose of the feeding scale. Only the feeding equipment for providing the source of medicinal materials and insects is introduced here. The format of the feeding pit is the use of old houses. For the time being, barns and toilets with roofs and walls are dug to a depth of about 67 centimeters. 70-100 cm wide. A pit of unlimited length (depending on the amount of feed and the actual situation in the house). Tamp the bottom of the pit and spread cement around it to make it smooth. For example, it is better to stick 3-7 cm wide glass to prevent turtle insects from escaping above the pit wall (931, 7.00, 0.76%). The pit is divided into several compartments with thin cement board or glass, and the size of each compartment should be standardized in order to calculate the amount of nymphs in different periods of raising and the yield per unit area. Put the feeding soil 20-27 cm thick in the pit, and then put in adults or nymphs of different ages. Separate feeding is easy to manage and feed. Because most of the feeding pits extend below the surface, the temperature in the pit is higher than the surface in winter and below the surface in summer, which can make the soft-shelled turtle less affected by the season, conducive to growth and development, and improve the survival rate. The structure of the semi-underground breeding pond is similar to the format of the feeding pit, only half of the pond is buried in the ground, the other half is higher than the ground, the pool is no longer divided, the pool is 2 meters long and 1.5 meters wide, and the semi-underground pond is suitable for feeding adults, propagating in large numbers and obtaining insect medicinal materials.

(2) preparation and treatment of breeding soil the soft-shelled turtle is a diurnal and nocturnal insect, which sneaks into the soil during the day and likes to look for food in the soil or on the soil surface, so the soil is the small living environment of this kind of insects. The quality of soil and the collocation of containing substances are directly related to the survival, growth and development of Trionyx sinensis. 1: soil quality and water content: the requirements for the selection of breeding soil should be adjusted according to its specific conditions, such as vegetable garden soil. Garbage. Ditch mud. Kitchen feet. Sand-clay mixed soil, at the same time mixed with an appropriate amount (20% Mel 30%) of fermented chicken manure. Pig dung. Horse dung. Coke mud ash or rice chaff ash. No matter what kind of soil is chosen, it should be loose in texture, rich in nutrition, moderate in dry humidity, clutching and loosening. If the water content is measured, the water content should be 15% 20%. This kind of soil is easy for soft-shelled turtles to lurk. Get in or climb out and move around to find food at will. Looking for a mate. 2: the treatment of breeding soil: before the breeding soil is put into the pit or pond, it should be exposed to the sun. Sterilization. Worm by worm, and sift to remove impurities and bricks. Rocks. All factors that are not conducive to the life of Trionyx sinensis should be excluded as far as possible in advance. The thickness of soil laid in the pond should be different according to different ages or adult stages, and different densities and seasonal soil thickness should also be different in the same pond. Experience has proved that the thickness of soil for 1-4 instar nymphs, 5-8 instar worms and 9-11 instar nymphs should be 7-10 cm, 16-20 cm and 20-26 cm respectively. In the same pond, the soil with high population density should be thicker, and the soil with lower density is lighter; the soil is thinner in summer and thicker in winter; the soil of breeding insects is thicker than that of raising medicinal insects, so that the process of mating and spawning is less disturbed. Trionyx sinensis is an omnivorous insect. However, from the point of view of insect eating physiology and different degrees of gluttony to food, any omnivorous insect has its favorite food range. Under artificially controlled feeding conditions, the selection and matching of feed is directly related to the success or failure of feeding and the size of harvest. 1: feed types: generally can be divided into three different properties of feed: plant feed: including wheat bran, rice bran, cake, powder, broken rice, corn (2520, 10.00,0.40%) and other miscellaneous grain powder. After stir-frying to overflow fragrance, spread out to cool and feed. Animal feed: the leftover scraps of pigs, cattle, chickens, ducks and fish in the restaurant can be used as feed for its consumption, but can not be spoiled or deteriorated to prevent the soft-shelled turtle worm from becoming infected and dying. If possible, it can be processed into a loose mixture of bone and meat and stored in cold storage. Yellow powder bug. Earthworms, crickets, locusts, moths and other small insects are put to death and can be eaten. Earthworms can also be cultured artificially (except for medicine), which can be used to feed turtles as the most gluttonous. The food that must be matched with green feed turtle worms. Green cabbage, cabbage, lettuce, amaranth, sesame, broad bean, peanut, sweet potato and other leaves, pumpkin, loofah flowers and fruits can be fed. Cut pieces such as melon peel and yam are more favored to eat. The green feed should be kept fresh and clean. We should pay more attention not to pick green fodder sprayed with insecticides to prevent the poisoning and death of ground turtles. 2: matching feeding: in summer and autumn high temperature season, green fodder should be fed 1-2 times a day, put in in the morning and keep fresh. In order to increase nutrition, pumpkin flowers and towel gourd flowers are indispensable. The times and amount of feeding in a day should be mastered once every other day in low temperature months and 1-2 times a day in high temperature months. The amount of feeding is commensurate with the population density of pits and ponds. After each feeding, the surplus and shortage of feed should be observed, and in principle, we should master the consumption of concentrate and more than green fodder. We should not only feed the worms, but also avoid unnecessary waste and excess residues that lead to parasites and plant mites. Soft-shelled turtles should be fed less before and after desquamation, but not during peeling. When it is found that there is a lot of skin on the surface of the breeding soil, there is an urgent need for a lot of food, it is necessary to resume normal feeding in time. Hibernating period can not be fed, but the climate suddenly warms up, found that insects unearthed activities, should also sprinkle some concentrate feed for its feeding.
