发现部分渔农户虽然全部配备了增氧设备,但就其使用方法还存在一些不足之处,往往只把它当成“救命机”,而没有发挥出其“增产机”的作用。现就其该如何科学使用简略总结如下:
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、常年养殖过程中,若遇鱼、虾、蟹出现浮头缺氧状态,应立即全部开启增氧设备急救,增加水体中的溶氧,此时就当“救命机”。
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、在鱼、虾、蟹等旺盛生长季节,晴天的中午开启增氧机曝气1~3小时,充分发挥增氧机的搅水作用,促进上下层水体对流,能增加池水的溶氧,并加速了池塘的物质循环,改良了水质,减少了夜间浮头发生。
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、阴雨天气,浮游植物光合作用弱,造氧能力低,池塘溶氧不足,易引起浮头。在夜间应及早开启增氧设备,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、当大量施肥后,水质过肥时,要采用晴天中午开机和凌晨开机相结合的办法,改善池水溶氧条件,预防浮头。池塘使用杀虫剂、剂或微生物制剂后,开启增氧设备1~2小时,能使药物分散均匀,增强使用效果;同时3日内夜晚及时开启增氧设备,防止“转水”后造成的缺氧现象。
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、晴天傍晚与阴雨天中午不要开机,若开机会增加池塘的耗氧水层,加速了下层的耗氧速度,容易引起鱼、虾、蟹等养殖动物的缺氧。
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、有条件的塘口可以装一台测氧仪,只要溶氧低于3mg/L就应停止喂料,鱼池溶氧低于2.0mg/L,虾池溶氧低于2.5mg/L,蟹池溶氧低于3.0mg/L时,就开启增氧设备。
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.
总而言之,广大示范户们对增氧机的科学使用,除与以上的天气、水温、水质等有关以外,还应综合考虑养殖池塘与养殖品种的具体情况,根据池水溶氧变化规律,灵活掌握开机方法和开机时间,以达到合理科学使用增氧设备,起到增产与增效的目的。
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.
