For sea cucumber culture, the quality of the bottom material is one of the keys to culture. The aging of some ginseng circles has seriously affected the benefit of sea cucumber culture. The organic bottom of the pond has caused the flooding of aquatic plants, which is difficult to solve the problem of hypoxia, and the poisoning of returning to the bottom often occurs, and the peeling of floating ginseng is very serious. Therefore, most farmers began to realize the importance of cleaning the circle, but cleaning the circle could not solve all the problems. How to do a good job in the management of cleaning pens and new cleaning pens is the key to the success of follow-up farming. Here we give the following suggestions.

First, clear? circle

1, ploughing? The aging of the bottom of the pond is not too serious, and the ginseng circle with little long grass can be directly ploughed with a hook machine or a tiller used for farming. It is best to drain the water before ploughing, and at the same time use 300 kg/mu of quicklime for treatment. It can not only effectively sterilize, but also improve the total alkalinity and redox potential at the bottom, enhance the overall buffering power of the pond, reduce the water change and return to the bottom, and make the sea cucumber culture more smooth.

2. Dredging? Due to perennial water inflow, mud and sand accumulated in some participating circles, resulting in submerged reefs and no habitat for sea cucumbers, mud pumps can be used for dredging. However, ponds with serious aging or long grass and serious damage to the bottom environment must be backfilled with new soil after overall dredging. The bottom of such a pond is very hard after dredging, so it is necessary to splash more water (preferably muddy water). When a small amount of soil accumulates at the bottom, use "Qing Tang Xiu An" for disinfection.

Remind everyone: after cleaning the circle, the bottom of the circle must be leveled, and the small pit is easy to accumulate dirt, which will cause serious damage to the stocked ginseng seedlings.

Second, raise? water

1, detoxification? The use of multiple organic acids can reduce the influence of toxic and harmful substances on the survival rate of ginseng seedlings, and also provide a good breeding environment for bacteria and algae.

2. Replenishing bacteria and carbon: In order to quickly restore the biodiversity of the pond, stabilize the water body and reduce the loss of ginseng seedlings caused by water change, we can use "more stable water+more beneficial bacteria" to supplement bacteria and carbon, with outstanding results.

Third, release? seedling

1, picking seedlings by hand: after using anti-stress drugs two hours before releasing seedlings, put them directly on the reef or cage.

2. Shed seedlings: It is best to put the ponds with cages in the cages for 3-5 days. In the process of seedling slow-down, if the condition is not good, the "activation+nutrition express line" can be continuously sprinkled in the cages to help the seedlings adapt and recover and improve the survival rate of seedlings.

Fourth, release? Miao? After? Tube? reason

1 Supplementing exogenous bait: Since there is not much natural bait at the bottom after clearing, it is necessary to supplement exogenous "Li Miao Duo" after releasing seedlings. It can not only provide bait for ginseng seedlings to eat, but also play a role in supplementing bacteria.

2. Fertilizing water: After the seedlings are released, it is necessary to fertilize the water properly in order to stabilize the water quality of the pond because everyone is afraid that the seedlings will not touch the water for more than ten days. While making the pond environment good, it also supplements natural bait for sea cucumbers.

Finally, according to the statistics of the overall pond cleaning in 20 17 years, 60% ponds have peeling phenomenon, of which 20% are serious, and the remaining 40% may not find any problems due to careless observation. Therefore, we should not take any chances, do a good job in managing every detail of the new Qing circle and lay a good foundation for our new start.
