Method for cultivating selenium-enriched soft-shelled turtle

The invention discloses a method for cultivating a selenium-enriched soft-shelled turtle. The method comprises a step 1) of culturing aquatic plants in a culture pond; a step 2) of spraying selenium-enriched liquid to blade surfaces of the aquatic plants, spraying the selenium-enriched liquid once every other 7 days, continuously spraying the selenium-enriched liquid three times, and then spraying the selenium-enriched liquid once every month, wherein the selenium-enriched liquid is sprayed at 8-9 in the morning each time; a step 3) of feeding fries and young shrimps and snails with the aquatic plants as foods; a step 4) of placing soft-shelled turtles in the pond after half a month; a step 5) of utilizing corn and wheat which are rich in organic selenium to prepare selenium-enriched nutrient soft-shelled turtle feed, mixing the selenium-enriched nutrient soft-shelled turtle feed into feed special for soft-shelled turtles, preparing mixed feed, and feeding the soft-shelled turtles with the mixed feed, wherein
