高温季已经来临,很多养殖户会选择搭遮阴网来度夏。白天遮阴网能够有效阻挡光线,避免海参池升温过快,起到降温的作用。同样的,遮阴网也会阻碍风力,影响自然风增氧的效率,并且晚上遮阴网也会阻碍池水热量的散发,导致水分层、池底缺氧加重。往往我们忽视了水体中80%以上的氧气是来源于藻类和青苔的光合作用这个事实,我们在走访客户的时候经常听到,部分老板拉上遮阴网之后因为管理不当,导致海参在高温前就出事了。因此搭遮阴网后的池塘管理是一种全新的管理模式。
High temperature season has come, many farmers will choose to build shade net to spend the summer. During the day, the shading net can effectively block the light, prevent the sea cucumber pool from heating too fast, and play a role in cooling. In the same way, the shading network will also block the wind and affect the efficiency of natural wind oxygen, and at night, the shading network will also block the heat emission of the pool water, resulting in water stratification and the aggravation of oxygen deficiency at the pool bottom. We often ignore the fact that more than 80% of the oxygen in the water comes from the photosynthesis of algae and moss. When we visit our customers, we often hear that some bosses pull up the shade net, because of improper management, the sea cucumber has an accident before the high temperature. Therefore, the pond management after shading net is a new management mode.
当海参池塘安装上遮阴网之后,海参池的光照会受到影响,藻类和青苔的光合作用变弱,产氧能力变小;光线变弱,水体中主要以喜弱光的鞭毛藻类为主,白天产氧能力强,晚上耗氧量大;池底死亡藻类、青苔等有机质继续厌氧发酵升温,加重池底耗氧;自然风变小,水体流动变差,水体自净能力变弱,所以安上遮阴网之后是一套全新的管理方式。
When the shading net is installed in the sea cucumber pond, the light note of the sea cucumber pond will be affected, the photosynthesis of algae and moss will be weakened, and the oxygen production capacity will be reduced; the light will be weakened, and the flagellate algae that like weak light will be the main species in the water body, with strong oxygen production capacity in the daytime and large oxygen consumption in the evening; the organic matter such as dead algae and moss at the bottom of the pond will continue to be heated by anaerobic fermentation, which will increase the oxygen consumption at the bottom of the pond; the natural wind will change Small, the flow of water becomes poor, and the self purification capacity of water body becomes weak, so after installing the shading network, it is a new management method.
