1. Construction of aquaculture ponds Family sideline breeding is best done with a 4 to 5 square meter cement pond or a pool bottom to compact a 15 cm tri-soil pond. Collective sideline, can be more than ten square meters for a pool. The depth of the pool is about 1.5 meters. The pool is filled with 30 centimeters of thick mud, and some draft stalks and pigs and cow dung are added to the mud to increase organic matter. Stones and broken bricks are thrown again. Artificially caused cave conditions. After the pool is laid, the water depth should be about 15 cm. The wall of the pool rises above the surface 35. Centimeters or so. A drainage port is provided at a level with the horizontal plane, and an inlet is provided at a position slightly higher than the horizontal surface of the drainage outlet.
2. Seedlings stocking The first time breeding of Astragalus species, you can adopt the method of cage trapping to obtain seedlings, choose disease-free and injury-free, each weighing about half of the cubs rearing. Places that have cultivated yellow locusts can protect seedlings by protecting their young cubs through the winter. The seedlings of Astragalus are generally used for breeding young puppies in the previous year. They are stocked in April, and it is advisable to weigh about 25 grams of tail weight. The stocking rate is 1-2 kilogrammes per square meter, and seedlings should be generally uniform.
3. Baits and feeding Natural breeding 4 to 5 days after hatching seedlings can be fed leeches, rotifers and green algae. Cheng Shao can feed quail, snail meat, cocoon, wild fish and animal organs. Feeding quail grows best, every 8 grams of fresh quail, can increase the meat lg. Huang Hao likes to search for food at night, so it is appropriate to raise the bait at 4 to 5 pm or in the evening. After that, the feeding time will be increased from day to day. After about 10 days of bait, the bait can be given at 9 am or 2 pm every day, and the bait can be fed every other day. The daily feeding amount is 6% of the total weight of the carp. 7%, feeding in two early and late. After acclimation and feeding, the fish are fed regularly and at regular intervals. When the squid hears the vessel, a large number of squid are concentrated on the feeding site. Therefore, the bait station should be set when feeding. The bait station is a bait box made of wooden frame and nylon dense mesh, floating on a certain position in the Dianchi Lake, so that the yellow cormorant enters the table to eat. The water temperature of 15-28 degrees is its optimum growth temperature, feeding increased, and rapid growth. Therefore, it is necessary to feed and feed. When the water temperature is below 10 degrees, the food is stopped, and as the temperature drops, it enters the hibernation period.
4. Feeding and management are generally replaced with fresh water within 1-2 days after feeding, so that the water quality is good. Eli grows. In summer, in order to prevent the pool water temperature from being too high, it is possible to plant melons on the side of the pool to catch melon sheds, and in the winter to drain the pool water and add grass to prevent the cold. Size quail should be grading, in order to prevent weak meats.
Containerized Oxygen Cylinder Filling System
ETR can combine all parts of the Oxygen Cylinder Filling System into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks, Oxygen Generator and oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can reached to 15Mpa and fill in cylinders.
