It is found that although some fishing households are all equipped with oxygen increasing equipment, there are still some deficiencies in their use methods, which often only regard it as a "life-saving machine" and do not play its role as a "yield increasing machine". Here is a brief summary of how to use it scientifically:

1,、常年養(yǎng)殖過程中，若遇魚,、蝦,、蟹出現(xiàn)浮頭缺氧狀態(tài)，應立即全部開啟增氧設備急救,，增加水體中的溶氧,，此時就當“救命機”。

1. In the process of perennial breeding, if fish, shrimp and crab have floating heads and lack of oxygen, all oxygenation equipment should be turned on immediately for first aid to increase dissolved oxygen in the water body. At this time, it should be used as a "life-saving machine".

2,、在魚,、蝦、蟹等旺盛生長季節(jié),，晴天的中午開啟增氧機曝氣1~3小時,，充分發(fā)揮增氧機的攪水作用，促進上下層水體對流,，能增加池水的溶氧,，并加速了池塘的物質(zhì)循環(huán)，改良了水質(zhì),，減少了夜間浮頭發(fā)生,。

2. In the vigorous growth season of fish, shrimp, crab and so on, the aerator is opened at noon on a sunny day for aeration for 1~3 hours, giving full play to the role of the aerator in stirring the water, promoting the convection of the upper and lower water bodies, increasing the dissolved oxygen in the pool water, accelerating the material circulation of the pond, improving the water quality, and reducing the occurrence of floating heads at night.

3、陰雨天氣,，浮游植物光合作用弱,，造氧能力低，池塘溶氧不足,，易引起浮頭,。在夜間應及早開啟增氧設備，防止缺氧泛池。

3. In rainy weather, phytoplankton have weak photosynthesis, low oxygen production capacity, and insufficient dissolved oxygen in the pond, which is easy to cause floating heads. At night, the oxygenation equipment should be started as soon as possible to prevent hypoxia flooding.

4,、當大量施肥后,，水質(zhì)過肥時，要采用晴天中午開機和凌晨開機相結(jié)合的辦法,，改善池水溶氧條件,，預防浮頭。池塘使用殺蟲劑,、劑或微生物制劑后,，開啟增氧設備1~2小時，能使藥物分散均勻,，增強使用效果,；同時3日內(nèi)夜晚及時開啟增氧設備，防止“轉(zhuǎn)水”后造成的缺氧現(xiàn)象,。

4. When the water quality is too fat after a large amount of fertilization, the method of starting the machine at noon and in the early morning on a sunny day should be adopted to improve the dissolved oxygen conditions in the pool water and prevent floating heads. After using pesticides, disinfectants or microbial agents in the pond, turn on the oxygenation equipment for 1~2 hours, which can make the drugs disperse evenly and enhance the use effect; At the same time, the oxygenation equipment shall be opened in time at night within 3 days to prevent hypoxia caused by "water transfer".

5,、晴天傍晚與陰雨天中午不要開機，若開機會增加池塘的耗氧水層,，加速了下層的耗氧速度,，容易引起魚、蝦,、蟹等養(yǎng)殖動物的缺氧,。

5. Don't start the machine at noon on sunny evenings and rainy days. If you open the opportunity to increase the oxygen consumption layer of the pond, it will accelerate the oxygen consumption rate of the lower layer, which is easy to cause hypoxia of fish, shrimp, crab and other cultured animals.

6、有條件的塘口可以裝一臺測氧儀,，只要溶氧低于3mg/L就應停止喂料,，魚池溶氧低于2.0mg/L，蝦池溶氧低于2.5mg/L,，蟹池溶氧低于3.0mg/L時,，就開啟增氧設備。

6. If possible, an oxygen meter can be installed at the entrance of the pond. As long as the dissolved oxygen is lower than 3mg/l, the feeding should be stopped. When the dissolved oxygen in the fish pond is lower than 2.0mg/l, the dissolved oxygen in the shrimp pond is lower than 2.5mg/l, and the dissolved oxygen in the crab pond is lower than 3.0mg/l, the oxygenation equipment should be started.

總而言之,，廣大示范戶們對增氧機的科學使用,，除與以上的天氣、水溫,、水質(zhì)等有關以外,，還應綜合考慮養(yǎng)殖池塘與養(yǎng)殖品種的具體情況，根據(jù)池水溶氧變化規(guī)律,，靈活掌握開機方法和開機時間,，以達到合理科學使用增氧設備,，起到增產(chǎn)與增效的目的,。

In a word, the scientific use of the aerator by the majority of demonstration households, in addition to the above weather, water temperature, water quality and so on, should also comprehensively consider the specific conditions of the breeding pond and breeding varieties, and flexibly master the starting method and starting time according to the change law of dissolved oxygen in the pool water, so as to achieve the rational and scientific use of the aerator and achieve the purpose of increasing production and efficiency.
