| 英文摘要 | Soil respiration (R-s) from cropland in response to tillage practices contribute to global climate change. We quantified the effect of no-tillage (NT) and conventional tillage (CF) on R-s and precipitation in the North China Plain (NCP). An in-situ automatic sampling and measurement method was applied during the maize (Zea mays L.) growth stages in 2018 and 2019. The continuous daily R-s, soil water content and temperature were monitored during all the maize growth stages, whereas maize grain yield, aboveground biomass, and soil microbial biomass were measured after harvest. The mean R-s across tillage practices on bright days was higher in 2018 (16.69 g CO2 m(-2) d(-1)) than that in 2019 (12.99 g CO2 m(-2) d(-1)). Compared with CT, NT increased R-s on bright days by 31.44% in 2018 and 15.60% in 2019. However, mean R-s on rain-affected days across tillage practices was lower in 2018 than that in 2019. NT increased mean R-s after precipitation in 2018 (p < 0.05). The contribution of R-s after precipitation to cumulative R-s (across tillage practices) was higher in 2019 (51.90%) than that in 2018 (41.18%). Mean soil water content and temperature were higher in 2018 than that in 2019 (p < 0.05). NT increased soil water content on bright days in 2019. Furthermore, soil water content was more important in regulating R-s in 2018, while soil temperature was more critical after precipitation in 2019. Crop productivity was lower in 2019 than in 2018 (p < 0.05). However, neither crop productivity nor soil microbial biomass varied with tillage practices (p > 0.05). Overall, influence of tillage practices and precipitation on R-s were different according to soil water content. Therefore, it is necessary to decrease excessive irrigation to reduce R-s in dry years and to conduct continuous observations on R-s after precipitation in the NCP. (C) 2020 Elsevier B.V.
