作物表型高通量获取和智能解析为高效精准筛选优良种质资源提供技术支撑。2024年来,南京农业大学农学院智慧农业团队的作物表型监测组师生,利用地基激光雷达量化小麦冠层的叶角分布,取得了突破性进展。研究结果2024年4月4日以“Quantify Wheat Canopy Leaf Angle Distribution Using Terrestrial Laser Scanning Data”为题,发表...
The technology of canopy plastic mulching has been widely used in citrus orchards for protecting fruit trees from cold damage. Understanding the spatio-temporal dynamics of plastic-mulched citrus (PMC...
Afforestation is a strategy to protect croplands and to sequestrate carbon in coastal areas. In addition, inorganic carbon is a considerable constitute of the coastal soil carbon pool. However, the ve...
The cloud forests are threatened due to the climate change process. Investigations seeking to predict how future climate change will affect species are of great importance as they are fundamental to g...
Accurate information on tree species is in high demand for forestry management and further investigations on biodiversity and environmental monitoring. Over regional or large areas, distinguishing tre...
Habitat spatial distribution is essential to know where to focus the protection of the seafloor resources. In this work, the bathymetry and backscatter seabed data show the importance of remote sensin...
Species distribution models (SDMs) are currently the main tools to derive species niche estimates and spatially explicit predictions for species geographical distribution. However, unobserved environm...
The continued fraction is a very old and classical object. Its period is closely related to the solubility of the Pell equations, and also to the class group of quadratic fields. Last year, Koymans an...
日前,2018级博士研究生夏宇轩在国际学术期刊《分形》发表题为《一种基于多孔介质孔径分布的分形维数新计算方法》的论文,入选Mathematics学科领域高被引论文。在该论文中,夏宇轩提出了一种基于分形毛细管假设的计算多孔介质孔隙空间和迂曲度分形维数的新方法。
非线性光学因为它的高阶物理过程而独具魅力,在固体激光,物质探测,光子通信,量子纠缠,量子隐形传输等领域都有广泛应用。1961年科学家们在石英晶体中观测到了激光的二阶非线性过程。随后,非线性光学迎来了飞跃的发展。在非线性光学微观机理研究方面,从化学键、原子尺度上发展了许多理论模型和近似的方法,包括非谐振子模型、双能级模型、键电荷模型、键参数模型、电荷转移理论等,为非线性光学材料的内在机理和设计合成方...
Bacterial blight (BB) is an important constraint on achieving a high and stable rice grain yield. An increasing number of BB resistance (R) genes have been identified and cloned to increase the availa...
Nitrogen (N) fertilization is a commonly applied silvicultural treatment in intensively managed coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) plantations. Field trials were e...
A single drop of seawater can contain a wide representation of ocean microbes from around the world -- revealing new insights into the ecology, evolution and biotechnology potential of the global micr...
Recently, increasing attention has been paid to the anthropogenic degradation of the riverbed and its relationship to the ecological status of the adjacent river landscape. The key objective of this r...
Walnut is one the most popular nuts worldwide and contains various mineral nutrients. Little is known, however, about the relationship between toxic heavy metals in walnuts and growth soil. In this st...
