In February, there was less fat in the pond bottom, and digging pit composting around the pool edge. As the temperature gradually increased, the water level gradually increased, and the fermented mature manure naturally dissolved into the pool.
If the amount of plankton in the pond water is insufficient in March-April, and the transparency of the pool water is more than 40 cm, 50kg-100kg/mu of fermented manure water should be applied in a timely manner.
In the middle and late April of the year, egg-holding shrimps are generally present. At the same time, due to the large temperature difference between day and night and high oxygen consumption, the first Floating Head Festival of shrimp ponds is coming. The focus of water quality management should be changed from adding top dressings to changing water and increasing oxygen levels. In particular, in mid-May, the water quality changes rapidly, and more attention should be paid to changing the water, changing from the original 20 centimeters per half month to two or three times per week. When changing the water, it is necessary to add water first after draining water, but not on one side; use water pump to pump water; do not open the surface water in the ditch; change the water in the morning and change the water in the evening.
In June, the water quality in ponds tends to deteriorate. At this time, large areas should be changed and old water should be removed. At the same time, the drug is sterilized with water and replaced with fresh water. Due to the relatively rapid fertility consumption of juvenile shrimp in June, it is necessary to cast some animal manure and other animal manures in small quantities to promote the water quality.
In July-August, especially at the end of the second floating season beginning in late July and early August, fertilization should be stopped, and water changes and pond inspections should be stepped up. The transparency of the pool water is more than 40 m2, and brown green is preferred. If it is found that ponds are pooled on the edge of the pond and gathered on the grass, they should not be disturbed and the light should not be returned. Oxygen should be taken immediately to avoid accidents.
In addition, every time you inject and drain, you should check the nylon sieve and find that it is damaged and replaced in time to prevent wild fish and stings from entering the shrimp pond. As a means of supplementing calcium, 29 kg/mu of quicklime can be used to regulate the quality of water when breeding more than 3 cm of shrimp.
