Ecological breeding method for freshwater shrimp and bengal waterdropwort herb crop rotation

The invention relates to an ecological breeding method for freshwater shrimp and bengal waterdropwort herb crop rotation. The ecological breeding method comprises the following steps: (1) preparing a pond condition; (2) breeding seed bengal waterdropwort herbs; (3) stocking freshwater shrimps; (4) managing bengal waterdropwort herbs; (5) managing water quality; (6) managing feeding; (7) managing oxygenation; (8) controlling diseases; (9) harvesting the freshwater shrimps; (10) preparing a pond and fertilizing; (11) accelerating germination and rooting; (12) seeding; (13) managing a water level; (14) topdressing and weeding; (15) evenly arranging seeds and softening; (16) collecting the bengal waterdropwort herbs. Compared with the prior art, the ecological breeding method has the advantages that a pond land resource is fully utilized according to season difference of the bengal waterdropwort herbs and the freshwater shrimps, and breakthrough in a production mode is achieved; a pond ecotope is reasonably built and arranged according to the biological characteristics of the bengal waterdropwort herbs and the freshwater shrimps, and win-win is achieved; after the bengal waterdropwort herbs are bred in one season, and the pond soil quality is more favorable for the environment required by growth of the bengal waterdropwort herbs in winter no matter from the aspect of nutritional ingredients or the loose degree, so that labor cost is reduced.
