不同施肥类型对稻田氮素流失的影响

open access: yesShuitu Baochi Xuebao, 2021
采用田间试验探究了不同施肥处理对稻田氮素流失的影响,其中不同施肥包括对照(CK)、常规施肥(CT)、有机肥替代(BS)和炭基肥(CB)4个处理。结果表明:CB和BS组对降低稻田氮素径流流失的效果显著(p < 0.05),其中稻田铵态氮的径流流失总量CT组(20.08 kg/hm2) > BS组(15.53 kg/hm2) > CB组(12.68 kg/hm2) > CK组(0.63 kg/hm2)。通过估算不同深度土壤的铵态氮与硝态氮淋溶流失量可知,BS和CB组对降低稻田氮素淋溶流失的效果有限。CT ...

Broad‐Spectral Response Lead Halide Perovskite Solar Cells Through Integration of Multifunctional Organic Bulk‐Heterojunction and Quantum‐Cutting Downconversion Materials

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...
