玉米冠层耕层优化高产技术体系研究与应用中国农业科学院作物科学研究所,赵明研究员团队针对玉米密植倒伏早衰问题围绕着密植高产挖潜,创立了冠层耕层优化及二者协同的理论体系,构建了冠层“产量性能”定量分析体系,确立了玉米不同产量目标(9.0~15.0 t/hm~2)的定量指标,建立了动态监测系统;创建了耕层“原位根土立体分析”方法,探明了土壤与根系空间分布特征,提出
Research and Application of Optimized and High Yield Technique System for Corn Canopy Topsoil Research Team, Institute of Crop Sciences, Chinese Academy of Agricultural Sciences In response to the problem of premature failure of dense planting and lodging of corn, the research team focused on the potential of dense planting and high yield and established the theoretical system of optimization of canopy layer cultivation and their synergy , A quantitative analysis system of canopy “yield performance ” was established, the quantitative index of different yield target (9.0 ~ 15.0 t / hm ~ 2) of corn was established, the dynamic monitoring system was established, Soil Stereo Analysis "method to explore the spatial distribution of soil and root system characteristics, put forward
