Embodiment 1
[0034] A method for promoting the estrogen cream of Portunus trituberculatus, comprising the following steps:
[0035] (1) Selection of the ointment pool
[0036] The indoor cement pool is used as the ointment pool, the pH of the pool water is 7.8, the salinity is 18‰, the water depth is 1m, and the dissolved oxygen is ≥ 5g / m 3 , the water temperature is 18°C, ammonia nitrogen ≤ 0.4 mg / L, hydrogen sulfide ≤ 0.1 mg / L, the bottom of the ointment pond is covered with a sand bed, the thickness of the sand bed is 8 cm, and the area of the sand bed accounts for 1 / 3 of the bottom area of the pool.
[0037] (2) Disinfected fertilizer water in the ointment pool
[0038] After draining the pond water, soak the ointment pool in seawater with a bleaching solution concentration of 40ppm and a temperature of 5°C for 40 minutes, then drain it, rinse it twice with seawater, and apply ammonium carbonate 0.5Kg / mu and superphosphate 0.05 Kg / mu, let stand for 3 days, stand-by.
