中文摘要	探索黄土丘陵区增施有机肥对全膜覆土穴播小麦土壤碳氮含量及比值影响,为该地区小麦养分高效管理提供理论指导。于2016 ~ 2017年在甘肃省陇中半干旱区设置定位试验,设全膜覆土平作穴播(PMS)、全膜覆土平作穴播+有机肥(PMO)、裸地平作(CK)3个处理,研究各处理对春小麦生育期土壤碱解氮(SAN)含量、动态分布变化、碱解氮盈余,土壤有机碳(SOC)含量,土壤C/N(SOC/SAN),旗叶氮素含量,化肥偏生产力及水分利用效率和产量的影响。结果表明,在0 ~ 50 cm土层,PMO处理全生育期SAN含量较PMS和CK平均分别提高131.96%和64.39%;在0 ~ 30 cm土层,全生育期SOC含量较PMS和CK平均分别提高50.04%和44.23%。在挑旗-扬花阶段,PMO处理0 ~ 30 cm土层SAN含量下降幅度较PMS和CK平均增加了67.80%和201.62%;收获后PMO的SAN累积量在30 ~ 50 cm土层显著盈余。在挑旗期-成熟期,PMO在0 ~ 30 cm土层SOC/SAN较PMS平均降低22.25%,在0 ~ 10 cm土层SOC/SAN较CK处理平均降低60.22%。抽穗期-灌浆期,PMO旗叶全氮含量较PMS和CK平均提高4.44%和20.21%;化肥偏生产力平均提高5.13%和58.96%;水分利用效率提高26.49%和59.18%;产量增加了5.12%和59.00%。全膜覆土穴播条件下增施有机肥能够提升旱地春小麦耕层土壤碱解氮和有机碳含量,降低土壤C/N值,提高土壤氮素供应能力和延长肥效,显著提高产量和水分利用效率。
英文摘要	The effects of organic fertilizer application on soil carbon,soil nitrogen,and soil C/N of spring wheat under whole field soil-plastic mulching and bunch seeding were studied to provide theoretical guidance on fertilizer management efficiently in semiarid area.The field experiment was conducted in the semiarid area of middle Gansu province from 2016 to 2017,the involved three treatments were whole field soil plastic mulching(PMS),whole field soil plastic mulching and organic fertilization(PMO),non-mulched and bunch seeded(CK).The contents of soil available nitrogen(SAN)and soil organic carbon(SOC),SAN dynamic change and surplus,soil C/N(SOC/SAN),leaf nitrogen content,partial factor productivity,Water use efficiency(WUE) and the yield of spring wheat were recorded and calculated.The results showed that the PMO averagely enhanced SAN content at 0 ~ 50 cm profile by 131.96% and 64.39%,SOC content at 0 ~ 30 cm profile by 50.04% and 44.23% in the whole wheat growth stages respectively,as compared with PMS and CK.PMO significantly increased SAN content by 67.80% and 201.62% at 0 ~ 30 cm profile at the flag leaf stage to flowering stage,the observably surplus of the SAN accumulation at 30 ~ 50 cm profile were recorded in the harvesting stage,as compared with PMS and CK.From the flagging to maturing stage,PMO averagely decreased SOC/SAN by 22.25% at 0 ~ 30 cm profile,and 60.22% at 0 ~ 10 cm profile as compared with PMS and CK,respectively.PMO averagely increased total nitrogen content of flag leaf by 4.44% and 20.21% from heading stage to filling period,increased the partial chemical fertilizer productivity by 5.13% and 58.96%,the WUE by 26.49% and 59.18%,the yield by 5.12 % and 59.00% respectively,as compared with PMS and CK.Consequently,the application of organic fertilizer could increase the SAN and SOC content of topsoil,decrease soil C/N ratio,enhance the supplying capacity of soil nitrogen and prolong the longevity of fertilizer,which resulte in the significant increment of yield and WUE of spring wheat in semiarid area.
