Continuous rain and more boot

In summer, if it rains continuously, the light conditions are poor, the photosynthesis intensity of phytoplankton is weak, and the supply of dissolved oxygen in the water is low. However, the respiration of various organisms in the pond and the decomposition of organic matter require a large amount of oxygen, resulting in a shortage of dissolved oxygen in the water. , it is easy to cause the floating head of the breeding object. In addition, on cloudy and rainy days, the water is sometimes crystal clear, with few phytoplankton and many water fleas, which almost eat up the phytoplankton in the pond, resulting in lack of oxygen in the pond due to lack of photosynthesis sources of oxygen.

When the "oxygen debt" is large, it is necessary to switch on more

That is, it has been suy for a long time, the water temperature of the pond is high, the water quality is excessively fertilized due to a large number of feeding, the transparency is low, the water is rich in organic matter, the oxygen difference between the upper and lower layers is large, and the lower layer is too oxygen-deficient (oxygen debt).

At this time, in addition to prolonging the startup time, it is necessary to add new water to the pond, otherwise, the water quality will be excessively fertilized or the water quality will be deteriorated and cause hypoxia.

Does not tu on when baiting

Therefore, when the machine is tued on, the bait will be rotated to the center of the pond and Pond Aeration Equipment accumulated with the excrement, so that it is not easy to be eaten, resulting in waste of bait; do not tu on the machine in the evening, because the photosynthesis of phytoplankton is about to stop at this time, and oxygen caot be added to the water. The dissolved oxygen in the upper and lower layers of water is evenly distributed, and the dissolved oxygen in the upper layer caot be replenished after the reduction, while the dissolved oxygen in the lower layer is quickly consumed, which in tu accelerates the rate of dissolved oxygen consumption in the entire pond.

In short, when to start the machine and the length of the start-up time should be flexibly controlled according to the weather, the specific conditions of the farmed animals, and the load of the aerator. Generally, open at noon on a suy day, open in the early moing on a cloudy day, open in the middle of the night with continuous rainy days, not open in the evening, and open the floating head early, the weather is hot and the start time is long, the weather is cool and the start time is short, the start time in the middle of the night is long, the start time at noon is short, and the load surface is large. Long time, small load surface and short startup time strategy.
