我为增产做滴灌 ——记吉林省农业科学院研究员刘慧涛

Core Viewpoint - The implementation of integrated water and fertilizer technology in Jilin Province has significantly increased corn yields in saline-alkali soils, demonstrating the effectiveness of agricultural innovation in enhancing food security and improving living standards [1][4]. Group 1: Agricultural Innovation - The average yield of corn on lightly saline-alkali land reached 906 kg per mu, an increase of approximately 35.4%, while on moderately saline-alkali land, the average yield was 825 kg per mu, with an increase of over 30% [1]. - The integrated water and fertilizer technology allows for precise control of irrigation and fertilization, greatly improving the efficiency of water and fertilizer use, particularly in semi-arid regions [1][5]. Group 2: Historical Context and Development - Liu Huitao, a researcher at the Jilin Academy of Agricultural Sciences, has been instrumental in developing agricultural technologies since the 1990s, focusing on ecological restoration and efficient land use in sandy areas [2][3]. - The establishment of ecological governance and high-efficiency utilization demonstration zones in Jilin Province has led to a 16.3% increase in vegetation coverage and a 31.7% reduction in wind erosion intensity [3]. Group 3: Technology Adoption and Impact - The water and fertilizer integration technology has been adopted on approximately 5.253 million mu of land across Jilin, Inner Mongolia, and Xinjiang from 2022 to 2024, indicating a significant expansion of its application [7]. - The technology has been recognized as a key agricultural promotion technology by the Ministry of Agriculture and Rural Affairs for two consecutive years [7]. Group 4: Training and Knowledge Transfer - The promotion of water and fertilizer integration technology has led to about 50% of farmland in Dry County adopting this method, showcasing its widespread acceptance among local farmers [8]. - Liu Huitao's commitment to training and mentoring new agricultural professionals emphasizes the importance of knowledge transfer in advancing agricultural technology [9].
