In the autumn, it takes only two or three months to grow green shrimp, and it can produce more than 100 kilograms of shrimp per acre. The shrimp has large specifications and high aquaculture efficiency. 1. The conditions of the pond require that the water source be free from pollution and the injection and drainage are convenient. The pond area is 1.5 mu to 4.5 mu and the water depth is 1.2 meters to 1.5 meters. The bottom of the pool should not be too thick, about 5 cm. Sandy soil is better for the bottom. The pool width is more than 2 meters wide and the slope ratio is 1:3 to 4. The pool slope needs to have a large shallow beach foot, and the shallow water depth is about 0.4 meters. 0.5 kW to 1 kW impeller aerators per acre pool. After the pond is clear pond, there are small square-shaped or strip-shaped aquatic plants (water leeks or water peanuts) floating on the surface of the pond, accounting for 25% to 30% of the water surface. Second, the timely release of fresh shrimp in the autumn, shrimp should be in the early September lower pool, New Year's Day, before and after the Spring Festival into the shrimp market. Before juveniles are stocked for 7 days to 10 days, the ponds are filled with water to a depth of 80 cm. The influent water was filtered in order using a 40-mesh sieve. At the same time, 300 kg to 400 kg per mu of decomposed livestock and poultry manure, the whole pool evenly spilled through the residue of fertilizer. Before juvenile prawns try to “test water†to avoid excessive temperature difference. Generally, 15 kg of juvenile shrimp, 2 cm to 3 cm in size, is stocked per acre. When stocking, set a piece of screen net of 8 square meters horizontally in the pond, and enter the water depth of 8 cm to 12 cm. Slowly pour the shrimp into the middle of the mesh and allow it to free the mesh. After some time, the shrimps that are still on the mesh are removed. 3. After the feed is fed to the lower pool of juvenile shrimp, feeds are generally replaced by feeds of Macrobrachium rosenbergii. Production is usually based on feeding cakes, supplemented with wheat bran, rice bran and animal feed, such as minced wild fish, snails, oysters and so on. When the water temperature is 20 degrees Celsius, the daily feeding amount is about 10% of the whole pond shrimp weight; when the water temperature is 15 degrees Celsius, it is about 7%. As the water temperature decreases, the feeding amount decreases accordingly. Fourth, the daily management of prawns within 7 days after entering the pool, the water depth to maintain 1 meter. Gradually add water after 7 days and increase the water level to 1.5 meters within 1 week. Keep the pH of the pool water stable between 7 and 7.2. Change the water from 8 days to 10 days. The aerator is usually open at midnight from 1 midnight to sunrise and open all day in rainy days. Once the floating head appears, open the aerator in time and add new water. Fifth, prevention and treatment of disease is mainly based on disinfection and prevention. In general, lime water is splashed twice a month and 15 kg of lime are used per acre.
Sweet corn, also known as sugar corn, is a corn with high sugar content. Unlike field corn varieties harvested in the field when dried and matured, sweet corn is picked at immature (in the milk stage) and prepared and consumed as vegetables rather than grains. Since the sweet corn maturation process involves the conversion of sugar to starch, sweet corn needs to be eaten fresh or canned or frozen before it becomes hard and starchy. In order to provide a rich taste of sweet corn, we can make IQF sweet corn kernels by shelling and de-maturing sweet corn mature, soft, juicy and smooth corn cobs under the premise of strict hygiene. We can provide good quality and price. The iqf (Imported Quick Frozen) sweet corn is always dedicated to providing the highest quality products to our valued customers.
