Clean the cultivation rack every 20 days～30 days according to the monitoring water quality situation, will cultivate first rack and mention, clear up with giant again, change purification charcoal bag and middle cartridge bag once simultaneously; When the pH value of water in the shrimp pool is lower than 7 when being higher than 9, or greater than 0.15 mg/litre, throw in EM benefit rhzomorph and carry out water quality adjustment by the prawn pool greater than 0.25 mg/litre, nitrite for ammonia nitrogen;
(5), water circulation soil pick-up:
Carrying out the shrimp seedling threw in rear one month, the ON cycle ecosystem, water fender is arranged in the lower end of soil pick-up cover body, the screen pack lamella is arranged in the lower end of soil pick-up cover body with water fender, make the shrimp seedling be difficult for discharging outward, when shrimp aquaculture in the time of 2 months, water fender is to top offset, water fender fixes by spring catch and soil pick-up cover body, and this moment, the screen pack lamella to top offset, discharged dirt with water fender easily outward with filtering rod, prawn is blocked, the water source of high-quality is blocked by water fender, is not discharged from, discharge be sewage;
(6), open oxygen increasing equipment:
Use the oxygenation of nano oxygen enriching dish after the shrimp seedling is thrown seedling, open all oxygen increasing equipments when throwing seedling after 30 days, shrimp pool water body dissolved oxygen amount remains on more than the 4mg/L;
(7), patrolling the pool observes:
Patrol the pool every day and observe prawn food, active situation, in time process the shrimp that dies of illness, periodic monitoring water quality carries out disinfection to feed table, instrument, and strictly control cultivation unrelated person enters and exits culturing area, cultivation record palpus detailed complete;
(8), go out shrimp:
When shrimp is supported to 90 days～110 days, go out shrimp.
