To investigate the dynamics of dry matter accumulation and translocation, nitrogen uptake and utilization, and grain yield of spring wheat under different mulching practices, a field experiment was conducted in 2024 in the rainfed region of Northwestern China. Four treatments were applied: plastic film mulching (PM), straw strip mulching (SM), crushed straw mulching (CM), and a non-mulching control (CK). The effects of these mulching practices on dry matter and nitrogen accumulation, distribution, translocation, nitrogen use efficiency, and yield formation were analyzed. The results showed that mulching promoted aboveground growth and nitrogen accumulation in spring wheat, with the magnitude of increase ranking as PM>SM>CM. Dry matter and nitrogen allocation responded synchronously to mulching practices. Compared with CK, PM significantly reduced the dry matter and nitrogen distribution proportions in leaves at anthesis by 6.73% and 16.55%, respectively. Meanwhile, SM significantly increased the dry matter and nitrogen distribution proportions in grains at maturity by 5.39% and 6.63%, respectively, compared with PM. Mulching markedly influenced dry matter translocation. Compared with CK, PM significantly increased pre-anthesis dry matter translocation by 84.04%, while CM significantly enhanced post-anthesis dry matter assimilation by 48.46%, with SM exhibiting intermediate values. All mulching treatments significantly increased both pre-anthesis nitrogen translocation and post-anthesis nitrogen assimilation, with increase rate of 35.22% (SM), 32.43% (PM), and 21.26% (CM) for the former, and 34.51% (PM), 17.07% (CM), and 8.95% (SM) for the latter. Mulching also differentially affected nitrogen utilization. PM exhibited the highest nitrogen uptake efficiency, whereas SM and CM showed significantly higher nitrogen harvest indices than PM and CK. Furthermore, all mulching treatments significantly increased grain yield compared with CK, with yield increase rate of 33.10% (PM), 16.09% (SM), and 12.98% (CM). These findings indicate that mulching enhances grain yield by optimizing dry matter and nitrogen accumulation, allocation, and translocation in spring wheat. Taking yield, resource use efficiency, and sustainability into consideration, straw strip mulching (SM) is a highly promising mulching technology in spring wheat production in the rain-fed areas of Northwestern China.

为探究不同覆盖措施下春小麦干物质生产、氮素利用及产量的变化规律,于2024年在西北雨养区进行田间试验,设地膜全覆盖(PM)、秸秆带状覆盖(SM)、碎秆全覆盖(CM)和露地对照(CK)4个处理,分析其对春小麦干物质和氮素积累、分配、转运及氮素利用效率和产量形成的影响。结果表明,覆盖促进了春小麦地上部生长和氮素积累,且相对于CK的增幅均表现为PM>SM>CM;春小麦干物质和氮素在分配方面同步响应覆盖方式,PM的开花期叶干物质和氮素分配比例较CK显著降低,但SM的成熟期籽粒干物质和氮素分配比例较PM显著提高;覆盖显著影响了干物质转运量(P< 0.05),PM的花前干物质转运量较CK提高了84.04%,CM的花后干物质同化量提高了48.46%,SM干物质转运量介于PM与CM之间。覆盖均显著提高了花前氮素转运量和花后氮素同化量,SM、PM和CM花前氮素转运量较CK增幅分别为35.22%、32.43%和21.26%,花后氮素同化量增幅分别为8.95%、34.51%和17.07%;覆盖差异化影响氮素利用,PM的氮吸收效率最高,SM与CM的氮收获指数显著高于PM、CK;覆盖下春小麦籽粒产量较CK均显著提高,增幅分别为33.10%、16.09%和12.98%。由此可见,覆盖可促进春小麦干物质和氮素的积累、分配及转运,进而提高产量和氮素利用效率,其中秸秆带状覆盖综合表现较优,适合在雨养区春小麦生产中推广应用。

为探究不同覆盖措施下春小麦干物质生产、氮素利用及产量的变化规律,于2024年在西北雨养区进行田间试验,设地膜全覆盖(PM)、秸秆带状覆盖(SM)、碎秆全覆盖(CM)和露地对照(CK)4个处理,分析其对春小麦干物质和氮素积累、分配、转运及氮素利用效率和产量形成的影响。结果表明,覆盖促进了春小麦地上部生长和氮素积累,且相对于CK的增幅均表现为PM>SM>CM;春小麦干物质和氮素在分配方面同步响应覆盖方式,PM的开花期叶干物质和氮素分配比例较CK显著降低,但SM的成熟期籽粒干物质和氮素分配比例较PM显著提高;覆盖显著影响了干物质转运量(P< 0.05),PM的花前干物质转运量较CK提高了84.04%,CM的花后干物质同化量提高了48.46%,SM干物质转运量介于PM与CM之间。覆盖均显著提高了花前氮素转运量和花后氮素同化量,SM、PM和CM花前氮素转运量较CK增幅分别为35.22%、32.43%和21.26%,花后氮素同化量增幅分别为8.95%、34.51%和17.07%;覆盖差异化影响氮素利用,PM的氮吸收效率最高,SM与CM的氮收获指数显著高于PM、CK;覆盖下春小麦籽粒产量较CK均显著提高,增幅分别为33.10%、16.09%和12.98%。由此可见,覆盖可促进春小麦干物质和氮素的积累、分配及转运,进而提高产量和氮素利用效率,其中秸秆带状覆盖综合表现较优,适合在雨养区春小麦生产中推广应用。

To investigate the dynamics of dry matter accumulation and translocation, nitrogen uptake and utilization, and grain yield of spring wheat under different mulching practices, a field experiment was conducted in 2024 in the rainfed region of Northwestern China. Four treatments were applied: plastic film mulching (PM), straw strip mulching (SM), crushed straw mulching (CM), and a non-mulching control (CK). The effects of these mulching practices on dry matter and nitrogen accumulation, distribution, translocation, nitrogen use efficiency, and yield formation were analyzed. The results showed that mulching promoted aboveground growth and nitrogen accumulation in spring wheat, with the magnitude of increase ranking as PM>SM>CM. Dry matter and nitrogen allocation responded synchronously to mulching practices. Compared with CK, PM significantly reduced the dry matter and nitrogen distribution proportions in leaves at anthesis by 6.73% and 16.55%, respectively. Meanwhile, SM significantly increased the dry matter and nitrogen distribution proportions in grains at maturity by 5.39% and 6.63%, respectively, compared with PM. Mulching markedly influenced dry matter translocation. Compared with CK, PM significantly increased pre-anthesis dry matter translocation by 84.04%, while CM significantly enhanced post-anthesis dry matter assimilation by 48.46%, with SM exhibiting intermediate values. All mulching treatments significantly increased both pre-anthesis nitrogen translocation and post-anthesis nitrogen assimilation, with increase rate of 35.22% (SM), 32.43% (PM), and 21.26% (CM) for the former, and 34.51% (PM), 17.07% (CM), and 8.95% (SM) for the latter. Mulching also differentially affected nitrogen utilization. PM exhibited the highest nitrogen uptake efficiency, whereas SM and CM showed significantly higher nitrogen harvest indices than PM and CK. Furthermore, all mulching treatments significantly increased grain yield compared with CK, with yield increase rate of 33.10% (PM), 16.09% (SM), and 12.98% (CM). These findings indicate that mulching enhances grain yield by optimizing dry matter and nitrogen accumulation, allocation, and translocation in spring wheat. Taking yield, resource use efficiency, and sustainability into consideration, straw strip mulching (SM) is a highly promising mulching technology in spring wheat production in the rain-fed areas of Northwestern China.
