Effects of Supplemental Drip Fertigation on Grain Yield and Water and Nitrogen Use Efficiencies of Spring Maize in the Dryland Farming Region of the Eastern Loess Plateau

Water–nitrogen mismatch constrains stable and resource-efficient spring maize production in the eastern Loess Plateau. A two-year field experiment was conducted in Jinzhong, Shanxi Province, China, during 2024–2025. Supplemental irrigation was applied three, four, or five times i...

Effects of Supplementary Fertilization on Physiological Traits and Yield of Soybean Following Drought-Flood Abrupt Alternations of Varying Intensities

Drought-flood abrupt alternation (DFAA) events severely constrain soybean production, yet the physiological effects of supplementary fertilization and other measures following such events are unclear. This study investigated the effects of supplementary fertilization (SF) on the...

Improvement of Flow Channel Structure for Single-Wing Labyrinth Emitter

Abstract The anticlogging performance and clogging law of a single-wing labyrinth drip irrigation emitter were analyzed through hydraulic performance tests. On this basis, numerical calculation was carried out using computational fluid dynamics (CFD) technology, and the flow chan...

Integrated Adaptive Responses of Rhizosphere Microbial Communities and Functional Genes to Cadmium Stress in Ryegrass (Lolium perenne L.)

Heavy metal pollution impacts on soil microorganisms are of growing concern. This study employed high-throughput sequencing and qPCR to investigate rhizosphere microbial communities and functional genes responses in ryegrass (Lolium perenne L.) under cadmium (Cd) stress. Results...
