Core Viewpoint - The implementation of water-fertilizer integration technology in corn farming has significantly increased crop yields and improved resource efficiency in Qian'an County, Jilin Province, demonstrating the effectiveness of modern agricultural practices [1][3]. Group 1: Technology Implementation - The water-fertilizer integration technology allows for precise and timely delivery of water and nutrients to corn crops, resulting in an average yield increase from 1200 jin to 1600 jin per mu, representing a growth of over 30% [1][2]. - The technology has been adopted across 80,000 mu of land managed by a local livestock farm, with plans to apply it to 120,000 mu of the 2.88 million mu of arable land in Qian'an County this year [3]. Group 2: Resource Efficiency - The use of this technology enables a water savings of 26 tons per mu, with water and fertilizer utilization rates improving by 43.1% and 30.2%, respectively [3]. - The integration of advanced techniques, such as "water-fertilizer integration + dense planting," is being explored to further enhance productivity and efficiency [5]. Group 3: Soil Health Improvement - The adoption of practices like deep plowing of corn stalks and returning them to the soil has led to an increase in the thickness of the black soil layer from approximately 15 cm to over 20 cm in recent years [5].
