Core Viewpoint - The article highlights the innovative "rice-duck co-cultivation" model in Younian Village, where 20,000 ducks are utilized to clean up leftover rice grains after harvest, providing ecological benefits and enhancing local agricultural productivity [1][3][4]. Group 1: Ecological Benefits - The "rice-duck co-cultivation" model creates a symbiotic relationship where ducks help control pests, weeds, and provide natural fertilizer, while rice fields offer a habitat and food for the ducks [4]. - Ducks are introduced immediately after rice harvesting to consume leftover grains and pests, reducing feed costs and enhancing soil nutrition through their droppings [3][4].
