Four pay attention to earth culture
Artificially cultivated soil yuan is driven by breakthroughs in the consumer market and variety. The current market price of medicinal insects is stable at 23 to 26 yuan per kilogram, and the price of edible insects (frozen) is between 10 and 15 yuan per kilogram. In the following, four attentions are paid to the earth element culture to promote and improve the economic benefits of breeding. (1) Breeding facilities. According to their own conditions, a rearing pond can be built indoors or in a greenhouse. The size of the rearing pond is determined by the amount of rearing. The rearing pond is set up with a brick to establish a body rack type, with a 4.5-cm plastic strip around the pool. The bottom is treated with cement to prevent escape. Terra elements can also be kept in plastic or plastic pots. The pots and boxes are erected layer by layer to perform three-dimensional culture to fully utilize the interior space and increase production. (B) living habits. Tuyuan is an omnivorous insect that likes to live in dark, moist, humus-rich and fertile soils. It is mostly out at night for activities, feeding, and mating, and is afraid of direct sunlight. (c) Temperature requirements. Artificial cultured earth elements must be cultured at a constant temperature, suitable for activities at a temperature of 17°C to 38°C, and an optimum temperature of 23°C to 32°C. At such temperatures, earth elements can grow and spawn in four seasons. Scientific and rational feeding from larvae to adults takes 7 to 8 months, the shortest time is 6 months, a breeding room can produce two batches of adult per year. (D) feeding technology. Regardless of whether the breeding facility is a pond or a tank, it must be laid on the bottom with loose and fertile feeding soil, with a thickness of 5 cm to 15 cm. The thickness of the raising soil is determined by the age of the insect. The smaller the insect age is, the thinner the soil layer is. The water content of the rearing soil is kept at about 20%, and the relative humidity is kept at about 70%. The time for feeding the soil yuan should be selected in the evening, and once a day, the food should be fed with bran and washed leaves. Moderately add water and stir evenly into the surface of the feeding soil, so that the bran to be eaten can be eaten cleanly, and leafy vegetables are better.
