“绿肥+”让土壤吃上“营养餐”

Core Viewpoint - The research team from Gansu Agricultural University has developed innovative green manure planting models and supporting technology systems to enhance soil quality and reduce reliance on chemical fertilizers in the arid regions of Northwest China, thereby unlocking new opportunities for sustainable agricultural development [1][5]. Group 1: Research and Development - The project "Green Manure and Grain Crop Synergistic Efficiency Technology Innovation and Application" won the first prize of the Gansu Provincial Science and Technology Progress Award for 2024 [1]. - The team has created a new model for the synergistic planting of green manure crops and staple crops, significantly increasing soil organic matter content and achieving ecological cycling [1][5]. - The research involved customizing green manure planting models based on the unique climate and soil conditions of different arid regions, conducting extensive field trials to analyze crop growth, yield changes, and soil fertility [3][4]. Group 2: Economic and Ecological Benefits - The innovative techniques have led to a 20%-30% reduction in the use of chemical nitrogen fertilizers while significantly improving soil organic matter [5]. - The implementation of these techniques has resulted in tangible benefits for farmers, including increased crop quality and yield, as well as reduced pest and disease incidence [5]. - The green manure technology has been promoted across multiple regions, generating an additional 2.4 billion yuan in benefits for 3.55 million acres of land, contributing to the green development of agriculture in Northwest China [5]. Group 3: Educational and Community Engagement - The establishment of the "Gansu Liangzhou Green Manure Technology Small Courtyard" has become a training hub for farmers, with over 2,000 agricultural technicians trained to promote green manure technology [5]. - The team collaborates with various research groups to enhance the efficient use of resources and promote sustainable agricultural practices, focusing on soil health and crop quality improvement [6][7]. Group 4: Long-term Vision and Legacy - The team aims to transition Northwest agriculture from a resource-consuming model to a green and sustainable one, ensuring both increased productivity and longevity of the land [6][7]. - The foundational goal is to enhance both the productivity and health of the soil, aligning with the philosophy that "lucid waters and lush mountains are invaluable assets" [7].
