Blumeria graminis f. sp. tritici, the pathogen that causes wheat powdery mildew, is one of the most important diseases affecting wheat production in China, and the oversummering is the key stage of wheat powdery mildew epidemic. The more oversummering regionalization of wheat powdery mildew has played an important role in disease prediction, prevention and control. In this study, we analyzed the correlation between oversummering data of wheat powdery mildew and the meteorological factors over the past years, and determined that temperature was the key meteorological factor influencing oversummering of wheat powdery mildew. The average temperature at which wheat powdery mildew growth was terminated(26.2°C) was used as the threshold temperature to regionalize the oversummering range of wheat powdery mildew. This regionalization was done using the GIS ordinary kriging method combined with the Digital Elevation model(DEM) of China. The results showed that annual probability of oversummering region based on Model 26.2 were consistent with the actual survey of the more summer wheat powdery mildew. Wheat powdery mildew oversummering regions in China mainly cover mountainous or high-altitude areas, and these regions form a narrow north-south oversummering zone. Oversummering regions of wheat powdery mildew is mainly concentrated in the high-altitude wheat growing areas, including northern and southern Yunnan, northwestern Guizhou, northern and southern Sichuan, northern and southern Chongqing, eastern and southern Gansu, southeastern Ningxia, northern and southern Shaanxi, central Shanxi, western Hubei, western Henan, northern and western Hebei, western Liaoning, eastern Tibet, eastern Qinghai, western Xinjiang and other regions of China.

准确的植物叶片理化参数对于监测植物生长状况至关重要。随着深度学习技术的迅速应用,结合深度学习和高光谱遥感技术的植物叶片理化参数分析应用潜力巨大;然而,现阶段结合深度学习和高光谱遥感技术在植物多叶片理化参数的联合估算研究尚少。该研究旨在挖掘结合高光谱遥感技术和深度学习技术开展高精度的多植被叶片理化参数(叶绿素含量、类胡萝卜素含量、水分含量、蛋白质含量和碳基成分含量)联合估算的潜力。首先,通过利用新型PROSPECT-PRO辐射传输模型模拟分析,确定了多个植被叶片理化参数的敏感光谱区域,并设计了LeafTraitNet模型;然后,基于Lopex93数据开展LeafTr aitNet模型训练和验证,取得了高精度的叶片参数估算结果。得到以下结论:(1)基于PROSPECT-PRO辐射传输模型辅助实测开展植被光谱特征选择十分必要;叶绿素(约434和约676 nm)和类胡萝卜素(约445 nm)两类色素的光谱吸收峰均主要位于可见光区域;然而,其与叶片光谱的相关系数绝对值最大的点却不是各自的吸收峰位置,这可能是因为叶绿素和类胡萝卜素对光谱吸收的相互影响。(2)水分的吸收峰主要位于950~2500 nm范围内,这与叶片蛋白质和碳基成分的吸收区域重叠,因此削弱了后者的高光谱遥感估算精度。基于PROSPECT-PRO辐射传输模型和Lopex93数据集的叶片参数相关性分析结果表明,叶片水分含量与950~2500 nm范围内叶片光谱反射率相关系数绝对值接近1,而叶片蛋白质和碳基成分含量与950~2500 nm范围内光谱反射率相关系数较低。(3)三种传统统计回归方法和LeafTraitNet模型的叶片理化参数估算精度可以基于其估算总nRMSE而排序为:Le afTraitNet(总nRMSE=0.84)

Single-atom catalyst has garnered widespread attention to mimic mature enzymes due to its well-defined atomic structure and coordination environments. However, since the carbon–carbon（C–C） coupling reactions require synergistic catalysis of multiple sites, single-atom catalysts suffer from insufficient active sites and unclear reaction mechanisms. Controlling the reaction intermediates in a precisely targeted pocket through careful metal–organic cage design is therefore crucial. Here, we prepare a tetrahedral [Cu6L4]-type boron–imidazolate cage integrating highly active Cu sites and optimized cavity, which exhibits enzyme like specific catalytic performance in electrochemical CO2reduction reaction（CO2RR） to enhance the selectivity of *** analyses and computational calculations suggest that the single Cu site together with neighboring boron–imidazolate ligands provides suitably synergistic effects that enable the energetically favorable formation of an *COCHO intermediate, a key step determining selectivity. As a result, the [Cu6L4]-type cage of BIC-145 achieves a Faradaic efficiency of 28% for C2H4maintaining an average current density of -3.54 mA cm-2over a 5-hour electrolysis period. This work represents the first example for studying single-metal site catalysts with ultra-low coordination numbers through the rational design of metal–organic cages.
