摘要: 全球农业正面临着保障粮食安全与实现绿色可持续发展的双重挑战。设置膜下滴灌(FM)、无膜浅埋滴灌(NM)和覆膜漫灌(T)3种栽培模式,以及7.5万(低密)、9.0万(中密)和10.5万株/hm2(高密)3个种植密度,探讨其对玉米干物质积累量、产量形成及经济和生态效益协同机制的影响。结果表明,FM模式显著缩短玉米生育期,出苗期和成熟期较NM模式分别提前2.5~3.0和4.0~6.5 d;但NM模式的干物质积累量与FM模式无显著差异,且收获指数(HI)持平。高密度种植下,NM模式的籽粒产量与FM模式相当,但其单位产量温室气体(GHG)排放强度降低30.0%。NM模式消除地膜生产排放,减排贡献18.7%。经济方面,NM模式净收益较T模式提高87.3%,得益于地膜成本节省及水肥利用效率提升;环境方面,其单位产量GHG排放强度低于全球玉米生产均值。综上,NM模式在实现“吨粮田”目标的同时兼顾“低碳田”建设,为河套灌区探索粮食生产与低碳发展协同路径提供了理论依据。

Abstract:

Global agriculture is facing the dual challenges of ensuring food security and achieving green and sustainable development. Three cultivation modes, including film-mulched drip irrigation (FM), no-film shallow buried drip irrigation (NM), and film-mulched flood irrigation (T), and three planting densities of 7.5×104 (low), 9.0×104 (medium), and 10.5×104 plants/ha (high), were established to explore their effects on maize dry matter accumulation, yield formation, and the synergistic mechanisms of economic and ecological benefits. The results showed that the FM mode significantly shortened the maize growth period, with the emergence stage and maturity occurring 2.5-3.0 and 4.0-6.5 days earlier than those of the NM mode, respectively; however, there was no significant difference in dry matter accumulation between the NM and FM modes, and the harvest index (HI) remained comparable. Under high planting density, the yield of the NM mode was comparable to that of the FM mode, but its greenhouse gas (GHG) emission intensity per unit yield was reduced by 30.0%. The NM mode eliminated emissions from plastic film production, contributing 18.7% to emission reduction. Economically, the net income of the NM mode increased by 87.3% compared with the T mode, benefiting from plastic film cost savings and improved water and fertilizer use efficiency; environmentally, its GHG emission intensity per unit yield was lower than the global average for maize production. In conclusion, the NM mode achieves the goal of “ton-grain field” while simultaneously addressing the construction of “low-carbon field”, providing a theoretical basis for exploring the synergistic path of grain production and low-carbon development in the Hetao Irrigation District.
