[0010] Drain the water in the earth pond of the previous season, sprinkle 100~120kg of quicklime per mu, inject water after 2~3 days of light, start topdressing fertilizer 4~6 days before seedlings, and throw 120~145kg of livestock manure per mu to make the pool transparency at 20 ~30cm, and then put in loach summer flowers, the stocking density is 50-80 tails per square meter. The feeding amount is 1-3% of the body weight of the loach, and the feeding amount is increased as the temperature rises; the water is changed once a week in spring and autumn, and the water is changed every 2-4 days in summer, and the amount of each water change is 1 / 3 of the total water amount ~2 / 3. Loach summer flowers are soaked in salt water before feeding to prevent saprolegniasis, and at the same time, it can enhance the resistance of loach to pathogens. From June, when the temperature is higher than 25 degrees Celsius, 2 to 3 aerators per mu of ponds are guaranteed to operate. Sprinkle photosy...
