Highlights • We evaluated the effect of a ridge mulched system (RM) on soil water and inorganic N.• RM increased soil water storage and decreased evapotranspiration during the pre-silking stage.• RM increased soil inorganic N in the topsoil under the ridge and reduced N leaching.• RM led to high inorganic N accumulation in soil after three years maize cultivation.

垄膜对黄土高原土壤水分和无机氮分布的影响

亮点 • 我们评估了垄作覆盖系统 (RM) 对土壤水和无机 N 的影响。• RM 增加了土壤储水量并减少了预制丝阶段的蒸散量。• RM 增加了垄下表土中的土壤无机 N 和减少氮淋失。• 玉米种植三年后,RM 导致土壤中无机氮含量较高。
