告别粗放种植“一增五改”玉米增产超两成

Core Viewpoint - The "One Increase and Five Modifications" corn cultivation technology in Guizhou Province aims to enhance corn yield and efficiency, with a projected application area of 3.7193 million acres by 2025, representing a 15.3% increase from 2024 [1] Group 1: Technology Overview - "One Increase and Five Modifications" refers to increasing planting density, switching to high-yield varieties resistant to dense planting, changing from single to double planting, replacing nitrogen fertilizer with organic and balanced N-P-K fertilization, shifting from surface application to deep application of fertilizers, and transitioning from straw burning and shallow tillage to straw returning and deep tillage [1] - This technology addresses issues such as low planting density, insufficient fertilization, and poor management practices in corn production [1] Group 2: Demonstration and Results - In August 2025, a high-yield demonstration using the "One Increase and Five Modifications" technology in Bijie City achieved an average yield of 1,016.11 kg per acre, setting a new regional record [1] - The technology has shown a significant yield increase of over 20% compared to conventional methods, with successful demonstrations in multiple cities including Guiyang, Zunyi, Bijie, Liupanshui, and Anshun [1]
