First, it should be skillfully opened in the early morning at night. At night and in the early morning, the amount of dissolved oxygen in the pool is the lowest, and fish are susceptible to lack of oxygen. The best boot effect at night, generally should boot to sunrise.
Second, it should be a good day at noon on sunny days. Summer and autumn are the main growing season for fish. Each sunny day should be open for 1 to 2 hours at noon. This can break the hot water layer, use biological oxygen and combine mechanical oxygen, and fully utilize the supersaturated dissolved oxygen in the upper layer to accelerate the material circulation in the pond. . However, it should be noted that it is not advisable to turn on the power in sunny evenings. In the evening, it will cause convection in the upper and lower water layers in advance, but it will increase the oxygen-consuming water layer and the oxygen consumption, which may easily cause floating heads.
Third, the rainy weather should be skillfully opened. In cloudy and rainy days, the photosynthetic activity of phytoplankton in ponds is not strong, oxygen production is low, and oxygen consumption is high, which can easily lead to deterioration of pool water. It is necessary to start the plant early and extend the start-up time so as to give full play to the effect of mechanical oxygenation of aerators to prevent and rescue floating heads.
Fourth, the fishing season should be skillfully opened. Pay attention to the fish activity in the pond, during the high temperature during the late night of continuous rain, and during the fishing season. Since there are many fish in the pool, frequent pond inspections should be conducted to find abnormal conditions.
Fifth, different situations should be skillfully opened. High-temperature weather every day, boot, low temperature and less boot; sunny open at noon, cloudy early morning, continuous rainy night, open evening, floating head early open. The operating time can be taken as follows: long boot time in the middle of the night, short boot time at noon, long boot time for fertilization, application of pesticides, and hot weather; no start of fertilizers, no pesticide application, and short boot time when the weather is cool; long boot time in a pond area, pond area Small boot time is short.
