The invention provides a mixed farming method of Panulirus ornatus and Coccoloba uvifera, which comprises the steps of (1) preparing a farming pond; (2) putting in Coccoloba uvifera; (3) putting in fry of Panulirus ornatus; (4) providing daily management; (5) carrying out disease control; and (6) harvesting Coccoloba uvifera. According to the biological characteristics of Panulirus ornatus and Coccoloba uvifera, Coccoloba uvifera is inoculated by using a liftable farming floating bed, and the optimal illumination for the growth of Coccoloba uvifera is achieved by adjusting the height of the farming floating bed; the farming floating bed can create an appropriate shade environment for the benthic Panulirus ornatus, and the optimal illumination intensity for the growth of Panulirus ornatus is also achieved. The farming method of the invention has the advantages of low cost, good simplicity and convenience of operation and low bait usage, and is suitable for continuously producing fruitsof Coccoloba uvifera all year round, Panulirus ornatus farmed via the farming method has high survival rate, high growth speed, short farming period and good farming benefit, the utilization rate of afarming workshop can be increased so that large-scale popularization is benefited, and the farming method has a good application prospect.
