Abstract: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 i… Show more
