The Urine Reagent Strip Rapid Test is based on a double sequential enzyme reaction. One enzyme, glucose oxidase, catalyzes the formation of glucomic acid and hydrogen peroxide from the oxidation of glucose. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen to oxidize the chromogen to colors ranging from blue-green to greenish-brown through brown and dark brown.

Second, the fish species selection of stocking grass carp species should be physically strong, smooth surface, bright colors, shiny, disease-free, no injury, scales intact, strong top water, the lid does not immediately open after leaving the water. Before stocking, the selected species of summer fish should be immersed and sanitized with 3% to 4% saline.
Third, the bait half bucket to cultivate the summer fish and grass bait cultivation, generally in the fingerling pond cultivation of Euphorbia or duckweed, that is, a month before the grass carp summer stocking, the first clear pond, and then Shizujifei, generally using manure as Basal fertilizer uses 400 to 500 kg of manure per 667 square meters, and then uses bamboo to divide the water surface into a cross-shaped frame, and then puts 16 to 25 kg of castor bean or duckweed per 667 square meters into the box. After 15 days, apply 25-50 kg of manure every 667 m 2 every 2 days, or dilute it with 1 kg of ammonium bicarbonate and 0.5 kg of superphosphate and dilute it with water. Spray it every day, every morning, evening, and evening. Accelerate the breeding of duckweed.
Fourth, fish stocking Every 667 square meters of water generally rearing 4,000 to 5,000 grass carp, 500 carp, 1,500 carp, 10 herring, 2500 carp, 500 carp. When stocking, the main fish should be stocked early, which not only can ease the conflict between the scion and the fish and the space for fish, but also can further improve the specifications of the main fish and increase its bait ability.
Five, bait half-fighting feeding Xiahuacaoxiatang, do not need to feed at the beginning, to be eaten when the duckweed or small duckweed when the fast, spilled milk every day, and every day to feed 2 pounds per acre, grow to For more than 3 cm, feed 4 kg per lopper, more than 7 cm, and feed 10 kg of duckweed or verticillium per 1,000 pounds. After 20 days, when it grows to about 10 cm, you can feed it or young. Land grass and concentrate feed. From July to August, the amount of bait should be properly controlled and no feeding should be conducted at night. In late September, feeding should be strengthened to allow the fish to eat day and night.
Six, water quality management Summer fish grass fertilizer pond, after 20 days should be appropriate to control water quality, every 2 days recharge 1 new water, each 10 cm deep; side by side to part of the old water, the transparency of water quality can be maintained at 35 About centimeters to promote the appetite of grass carp. In the middle and late September, the number of water additions is gradually reduced, and fertilizers are chased at the same time. Once every 7 to 10 days, urea doses of 1.5 to 2.5 kg and phosphate fertilizers of 2.5 to 5 kg can be applied to each 667 square meter pond.
VII. Control of fish diseases After the grass carp grows to 10cm in length, it is susceptible to bleeding and enteritis. According to the principle of “disease-free prevention, disease early treatmentâ€, after entering in July, bleaching powder shall be splashed once every 15 days to a concentration of 1ppm. And every 20 days, spit an insecticide, King Exterminator and other insecticides. The treatment of bacterial grass carp disease generally uses chlorine dioxide, bromochlorohydantoin and other drugs, the treatment of grass carp parasite disease generally uses extermination, copper sulfate and ferrous sulfate mixture and so on.
The test area of the Urine Reagent Strip Rapid Test is specific for glucose; no substance excreted in urine other than glucose is known to give a positive result.Approximately 100 mg/dl glucose in urine is detectable.
The Urine Reagent Strip Rapid Test is based on the protein error-of-indicator principle. At a constant pH, the development of any green color is due to the presence of protein. Colors range from yellow for a Negative reaction, to yellow-green and green to blue-green for a Positive reaction.
