“…Some of this organic matter may be released into the soil by root exudates, increasing microbial community richness, affecting the decomposition of SOM, and subsequently impacting soil carbon sequestration and soil CO 2 emissions. 14,15 Water resource shortage is a serious challenge to agricultural production in NCP. Previous studies have shown that winter wheat is more sensitive to soil water deficits during the jointing stage compared to other growth stages.…”

BACKGROUNDThe shortage of water resources and the increase of greenhouse gas emissions from soil seriously restrict the sustainable development of agriculture. Under the premise of ensuring stable yield of winter wheat through reasonable irrigation scenario, finding a suitable straw returning method will have a positive effect on agricultural carbon sequestration and emission reduction in North China Plain (NCP).RESULTSStraw burying (SR) and straw mulching (SM) were adopted based on traditional tillage under in the winter wheat growing season of 2020–2021 and 2021–2022. Three irrigation scenarios were used for each straw returning method: no irrigation (I0), irrigation 60 mm (I1) at jointing stage and irrigation of 60 mm each at the jointing and heading stages (I2). Soil moisture, soil respiration rate, cumulative soil CO2 emissions, yield, water use efficiency (WUE) and soil CO2 emission efficiency (CEE) were mainly studied. The results showed that compared to SM, SR improved the utilization of soil water and enhanced soil carbon sequestration. SR reduced soil respiration rate and cumulative soil CO2 emissions in two winter wheat growing seasons, and increased yield by increasing spike numbers. In addition, with an increase in the amount of irrigation, soil CO2 emissions and yield increased. Under SR‐I1 treatment, WUE and CEE were the highest. SR‐I1 increases crop yields while reducing soil CO2 emissions.CONCLUSIONThe combination of straw burying and irrigation 60 mm at jointing stage is a suitable straw‐returning irrigation scenario, which can improve water use and reduce soil CO2 emission in NCP.This article is protected by copyright.
