    Controlled-release nitrogen combined with ordinary nitrogen fertilizer improved nitrogen uptake and productivity of winter wheat by Muhammad Fraz Ali, Ruifeng Han, Xiang Lin, Dong Wang

    Published 2025-01-01
    “…In order to improved winter wheat yields through effective N utilization, N2 application (240 kg ha-1) with the combination of (F4) 30% ONF + 70% CRNF would be recommended for northwest region of Shaanxi province in China. By increasing the amount of N accumulation at the anthesis stage, N transport is significantly increased after anthesis, and N accumulation and distribution ratio in grains are significantly increased at maturity.…”

    Coupling analysis of multi-systems urbanization: Evidence from China by Junqiang Luo, Weijing Ma, Shuang An, Zining Zhang, Yanchuan Fu, Hejun Huang, Genying Chang

    Published 2025-01-01
    “…Low-coordination cities are mainly found in the Qinghai-Tibet Plateau, Yunnan-Guizhou Plateau, the border areas of Gansu, Shaanxi, Sichuan, Chongqing, and Hubei, the Hetao area of the Yellow River Basin, the agricultural regions of the Huanghuaihai Plain, and the southeastern hilly and mountainous areas. (2) The degree of uneven urbanization development initially expands and then contracts, with intra-regional imbalances following the pattern: “Eastern Coastal Area > Northeast Area > Middle Reaches of the Yangtze River Area > Northern Coastal Area > Middle Reaches of the Yellow River Area > Southwest Area > Southern Coastal Area > Northwest Area.” (3) The coupling and coordinated development of urbanization is closely related to the economic foundation and production energy usage. …”
