用上无人驾驶收割机，麦收效率提升七成多（经济聚焦·夏收里的“新选手”）

Core Viewpoint - The implementation of smart farms and the use of unmanned harvesting machines in Jiangsu's Zhenjiang City significantly enhance agricultural efficiency and productivity, addressing challenges posed by the region's hilly terrain [2][4]. Group 1: Smart Farm Implementation - The smart farm in Hezhuang Village utilizes three unmanned harvesting machines that can operate continuously, with each machine capable of harvesting approximately 200 acres in a 24-hour period, improving efficiency by over 70% compared to traditional methods [4][5]. - The introduction of smart farming technology aims to resolve issues related to labor shortages and agricultural productivity in hilly areas, where traditional farming yields are about half of those in flat regions [2][4]. Group 2: Technological Advancements - The unmanned harvesting machines are equipped with advanced features such as a navigation system, multiple cameras for situational awareness, and pressure sensors to monitor grain storage, allowing for automated operations and real-time adjustments [4][5]. - The use of AI technology in smart farming enables automatic identification of pest issues and crop growth monitoring, which has led to an increase in wheat yield from 500 pounds to over 1000 pounds per acre [5]. Group 3: Economic Impact - The cost savings from reduced labor needs—where one operator can manage multiple machines instead of three—result in a two-thirds reduction in labor costs [4][5]. - The expected return on investment for the initial setup of smart farming technology is projected to be achieved within four years due to increased efficiency and expanded operational capacity [5].
