1. Build a large-scale rearing pond with a brick ash structure. It is 3 to 4 meters long, 2 meters wide and 2 meters deep. The bottom is filled with 1 meter thick loam and pressed slightly. Fill in 20 cm thick moist and loose manure-containing or humus-containing soil, sprinkle a layer of fermented cow dung or horse dung, crushed wheat stalks, and wheat bran on the surface as a raft activity and protective layer, and loosely put a layer of long wheat straw on it. Corn cobs, straw, etc. Shade and insulation, pool mouth covered with iron yarn cage. 2. There is a strong phototaxis in the seedlings, which can be trapped in the field near the village after dark days using electric or black light lamps from April to May and from September to October every year. The trapped adult insects were extirpated from the incomplete, thin, diseased, and severely worn individuals and processed into commodities, leaving the elite individuals to retain the species. The two cockroaches were kept in separate ponds and 10 pairs of insects per square meter per pond were used. 3. The green feeds for feeding and managing crickets include wheat seedlings, cereal seedlings, corn, sorghum, young leaves, melon peel or other leaves, etc. The concentrated feed has cooked dried grains, fried bean cake, peanut cake residue, and wheat. Bran and so on. Feeding in the evening, it is better to feed the ingredients. Green feed is fed daily and concentrate feed is applied once every 1 to 2 days. Diligently cast, cast less, and prevent mildew. Concentrate processing into blocks can avoid and reduce mildew. The preparation methods and formulas are as follows: 5000g of dry powder for grass seedlings, 500g of wheat bran (saute), 50g of dry yeast, 1000g of bean cake powder (fried), 1500g of clear water. Ml. The above feed was stirred into a thick paste, pressed into small pieces and dried in the sun. When it is fed, it is crushed into the size of rice and put into the pool. At the same time, it is fed with green feed. If the temperature in the rearing pond is too high, it can shade or splash water around the pool. If it is too dry, it can splash some water in the pool and increase the humidity. In the winter, wind barriers can be set up along the pool and the straw can be kept warm. 4. Harvesting and processing of artificially reared oysters, Oriental oysters harvested once a year, North China worms harvested every other year, once adults. Every spring in the spring, 20 cm deep humus soil inside the pond is used to remove adults with large-mesh sieves and remove debris, leaving a part of high-quality insects as species worms, and found that there are more insects in the soil, and agglomerates or parasites, etc. should be replaced. Clay. The adults will be removed to the head, wings and feet, the internal organs will be removed, washed, and burnt in boiling water, dried or dried. Food can be directly fried with fresh insects, fried, boiled, steamed and processed into flavored foods.
