Alice mouth red? Summer flower cultivation winter piece technology
First, the stocking preparation before stocking should be clear before the summer flower pond disinfection, it is best to drain the pool water drying pond about 20 days, then water injection 10 cm, with lime 100 ~ 150 kg / acre after the Quanchiposa disinfected pulp, after a week Pond water injection 1.2 meters. In the week prior to stocking summer flowers, 10% to 20% of EM biological preparations were added to stir the fermented water for 3 days, and 30 kg/mu was applied to the pond water to cultivate natural plankton. If the time is tight, bleaching powder or alternatives should be used to clean the pond. After 3 to 5 days, the water will be used as fertilizer. Second, the stocking of the first kind of oxygen carrier bags into the pond water for 30 minutes, if the sunny day is high, use a large basin to take the pool water, the fish slowly poured into the basin and the secondary water temperature, the detected temperature difference does not exceed 2 °C Put the fry into the pond. Acre 08,000 to 10,000, can be bred into winter specifications 13 to 15 centimeters; acre to 0.6 to 0.8 million is better, suitable for the cultivation of large-size winter pieces. Third, feeding and management 1, feed feeding: During the cultivation of fish species must always maintain a certain degree of fat, especially early enough natural zooplankton is very important. The next day, the powdered feedstuff can be put in the pond, such as fishmeal mix flour, and the conventional fish seed crushed material (protein content 30%~35%) can also be used. The amount of daily input increases as the growth period increases, generally from 0.8 to 1 kg/mu (0.5 to 0.8 kg of crushed material plus 0.2 to 0.4 kg of fish meal) → 1.2 to 1.5 kg/mu (1 to 1.2 kg of crushed material Add 0.5 to 0.8 kg of fish meal) → 1.8 to 2.5 kg/mu (1.2 to 1.8 kg of crushed material plus 0.8 to 1.2 kg of fish meal), and the number of shots per day is usually not less than two times. The amount of feed to be fed at each stage should be based on weather and fish The growth of sampling conditions for the corresponding increase or decrease. 2. Regulation of water quality: The depth of water at the pond is 1.2 meters, and new water is gradually added to 1.8 meters according to the rising water temperature. High-temperature season transparency is 0.3 meters or more, water quality requires fertility rate, daily aerators are activated to maintain high dissolved oxygen, and if necessary, uninterrupted circulation of micro-flowing water is used to improve the water quality of aquaculture waters. In late September, water quality is considered too low according to water quality conditions. When the quantity of natural zooplankton is insufficient, proper fertilizer should be used.
