According to the country's winter shed breeding experience and Yangjiang's unique local breeding environment, I suggest that I hope to help the vast number of winter shed farmers:
First, hardware facilities
1. Immediately take measures against the shed that has already been scraped and make up the shed.
2. Adhere the sticks of the winter shed iron tape to the air, minimize the convection with the outside air, and maintain the maximum temperature inside the shed.
3, conditions can be modeled on Jiangsu Rudong small shed breeding technology, adding boilers (because East East's winter shed temperature is much lower than the temperature in Guangdong).
Second, shrimp pond management measures
1. For the winter shed that has been planted, try to put the water and fertilizer together as much as possible because of the effect of water and fertilizer.
2, in the dissolved oxygen sufficient conditions to minimize the aerator, reduce heat, the general water temperature in the water will be relatively reduced consumption of oxygen, dissolved oxygen is relatively high.
3, shrimp do not eat at low temperature, so do not feed, spilled multi-dimensional and other nutrients to improve cold resistance.
4. With less use of biological agents, the temperature biological preparations have poor activity and the effect is not obvious. It may also increase the oxygen consumption of water bodies.
5. When oxygen is not enough, use as little oxygen aerator as possible, and use more oxygen products to reduce heat loss.
