Indoor three-dimensional culture method

General use of cages, terrarium boxes can be used wooden boxes, plastic food boxes or scrap wood, bamboo, wicker production. Fir, aromatic coniferous wood and wood containing tannins or turpentine are harmful to earthworms. Lead paint or phenol oil is harmful to earthworms and cannot be used as a breeding box. The size and shape of the box are indefinite. Each box area should not exceed 1 square meter, which is convenient for movement and management. The length, width and height of the rearing box are generally of the following specifications: 50.835.615.2 (cm, the same below), 603020, 604020, 605020, 605025, 402030, 403530. The bottom of the tank and the side of the tank shall have drainage and ventilation holes. There must be symmetry of handle handles on both sides. The thickness of the feed should not exceed 20 cm in general, and it can be thickened in winter. Too much charge, easy to ventilated; too little charge, feed is easy to dry, affect the growth and reproduction of earthworms. The surface of the feed should be covered with plastic film, waste paperboard or rice straw, and the dew can be connected to keep the feed moist and reduce the evaporation of moisture in the feed. The size of the box hole is preferably 0.7-1.5 cm in diameter, and its area may account for 20-35% of the box wall area. In addition to the ventilation holes in the box hole, it is also possible to control the box temperature from being too high due to feed fermentation. At the same time, part of the earthworm feces will gradually fall from the box hole to facilitate the separation of earthworm feces. The boxes are stacked and raised so that it becomes a three-dimensional box culture. This can make full use of space, increase the amount of breeding, facilitate management, and is suitable for professional cultivation throughout the year. The bed structure can be provided with angle iron welding or bamboo wood frame breeding box placed on the bed, generally 4-5 layers is appropriate, ? bed room with a working path, 1.5 meters wide. A 50 cm 25 cm air inlet door can be installed on both sides of the interior door and a ventilating air duct can be installed on the roof to facilitate indoor gas exchange. In the winter, the heat of steam from the nearby factories can be used to adjust the temperature, and it can generally be kept at about 18°C. In the middle of the room, electric or fluorescent lamps can be installed for night lighting to prevent escape. The breeding density of the indoor box raising method should generally be 5,000-10,000 pieces per square meter, and the feed layer be covered with a layer of polyethylene plastic film to reduce the evaporation of water. When the outdoor temperature falls to -1°C in winter, the heating device must be activated in time to allow the room temperature to rise to about 18°C ​​and remain relatively stable. The indoor valve can be opened 2-3 times a day to keep the air fresh. In summer, all the valves should be opened, and the feed layer and the ground are often sprayed with cold water to cool and moisturize. With the growth of the carcass, the culture density of caries in the carton can be appropriately reduced. In the box of 604020?cm size, at the beginning, each box can be stocked in 2000, and under the conditions of better temperature (20°C) and humidity (75-80%), breeding can be increased after 3-5 months. To 18,000. When the baskets are stacked and put on shelves, the gap between the upper and lower left and right sides is 5 cm, so as to facilitate air circulation. The advantages of this culture method are: Small footprint, low manpower, easy management, and higher production efficiency than flatland culture. If the scale of cultivation is large, indoor three-dimensional bed breeding can be used. This method can further reduce production costs, reduce labor intensity, and facilitate the growth of alfalfa in the four seasons. Breeding production increased by 2-3 times over the flat raising method. The indoor three-dimensional bed is generally built with two rows of left and right. Each line is one meter in width and the length depends on the depth of the room, leaving a pedestrian path in the middle. The main materials for construction are bricks, cement, sand and gravel. Generally six layers is appropriate, too inconvenient to operate. The height of each floor is reduced from the bottom to the top, such as 40 centimeters in the first and second floors, 35 centimeters in the third and fourth floors, and 30 centimeters in the fifth and sixth floors. The total height is 210 cm. From the second floor, two slabs of cement with a thickness of 5 cm, a length of 105 cm and a width of 50 cm were placed in parallel. Each floor is one meter apart from the left and right. Stack the two holes upward with bricks to facilitate ventilation. In order to pay attention to economy and ease of moving masonry, 105 cm length can be used when pouring concrete boards. Four bars of finger thickness are used instead of steel bars. The weight of each cement board is controlled at about 70 pounds, and the ratio of cement, sand and gravel is 1:3:5 when pouring. The built-up three-dimensional beds resemble medicine cabinets in pharmacies, and each feed bed is one square meter. In front of the bed (on both sides of the sidewalk), colored curtains or colored plastic films with a width of 100 cm and a length of 210 cm should be hung for shade and wind, creating a dark and quiet habitat for the beaks inside the bed. Management points: (1) The thickness of the first feed is generally 10-15 centimeters per bed; the standard feed is 8-12 centimeters. The system is effective for raising cockroaches. Its production method is: 100 jins of clear water, 40 jins of 糠 ,, 0.2 jin of urea. Dissolve the urea in water first, and then add the reconstituted mixture. After about 7 days (?Slightly short in summer, slightly longer in winter), ferment and serve. After the fodder is placed in the ravioli, 1000-2000 pieces of clams are placed. When adding material, it is necessary to wait for the surface of the material to be decomposed and scraping off the dejecta. Each time the thickness of the material is fed, the material is generally 5 cm and the material is 3 cm. When breeding alfalfa all year round, add feed to master thin materials and apply thick summer to thick winter and spring and autumn. (2) Moisturizing. On the feed surface, cover a piece of bamboo with a square meter, a fixed bamboo strip on both sides, and a roll of feed film that can be rolled to provide a moisturizing effect. If you need to spray water, sprayers should be used to achieve even humidity. (3) Accept feces. To facilitate collection of manure, small bamboo or culm pieces of one meter long can be laid flat on the surface of the material and under the plastic film. When the manure is scraped, the blade (any hard piece can be made only with small bamboo) "Shadow," Scrap the manure once to the edge of the bed and put it in a container for poultry and livestock. Other management is the same as conventional feeding.
