Abstract

Abstract:

【Objective】 Study the effects of different straw returning methods and plastic film mulching on soil water and nutrient contents, yield and water use efficiency of spring maize (Zea mays L.) in arid areas in order to find out the effects of different straw returning methods on fertility and yield, and to seek a green and efficient way of straw utilization in the hope of providing scientific and technological support for high-quality agricultural development in arid areas of Northwest China. 【Methods】 A field experiment was conducted in Huining County, Gansu Province from 2019 to 2020, six treatments were set up, namely straw returning to the field without plastic film (CK), straw comminution returning to the field (SS), straw fermenting returning to the field (FS), straw returning to the field without plastic film mulching (Mk), straw comminution returning to the field + plastic film mulching (MS), and straw fermenting returning to the field + plastic film mulching (MFS), soil water content, water storage and water consumption, soil carbon, nitrogen, phosphorus and potassium, crop water use efficiency, dry matter accumulation and yield were measured. 【Results】 Under the two treatments of plastic film mulching, the water storage and water use efficiency of plough layer increased by 7.33%-16.29% and 10.73%-19.25%, respectively, the water storage and water use efficiency of plough layer increased by 6.39% and 7.38% compared with that of straw comminution. Plastic film mulching could further increase soil water storage and water use efficiency by 10.62%-16.29% and 13.88%-18.87%, respectively, and increase soil nutrient content, the contents of soil organic carbon, total nitrogen, available phosphorus and available potassium increased by 0.70%-8.03%, 1.63%-8.01%, 7.75%-13.86%, 9.19%-40.48% and 4.06%-10.62%, respectively. Compared with straw returning or film mulching, the dry matter quality and yield increased by 3.10%-15.35%, 11.02%-17.08%, 1.84%-12.81%, 8.94%-14.83%, respectively, the average was 12.04% and 10.08%. 【Conclusion】 Straw returning and plastic film mulching can improve soil water supply and fertilizer supply by regulating soil moisture and nutrients, and then promote the synchronous increase of crop dry matter accumulation and yield. The effect of MFS is better than that of MS, which was beneficial to the multiple objectives of drought resistance, fertilizer increase, efficiency increase and high yield of spring maize.

摘要：

【目的】研究干旱区不同秸秆还田方式与覆膜处理对农田土壤水分和养分含量及春玉米产量和水分利用效率的影响,分析不同秸秆还田方式的农田培肥和增产效应,筛选西北旱区绿色高效的秸秆资源化利用方式,为旱区农业高质量发展提供科技支撑。【方法】于2019~2020年在甘肃省会宁县设计大田试验,设置秸秆不还田+无膜(CK)、秸秆粉碎还田(SS)、秸秆发酵还田(FS)、秸秆不还田+覆膜(MK)、秸秆粉碎还田+覆膜(MS)和秸秆发酵还田+覆膜(MFS)6个处理,测定不同秸秆还田与覆膜处理下土壤水分含量、贮水量和耗水量、土壤碳氮磷钾、作物水分利用效率、干物质累积量和产量。【结果】2种覆膜处理下,秸秆还田可使全生育期耕层贮水量增加7.33%~16.29%,水分利用效率提高10.73%~19.25%,其中,秸秆发酵还田的耕层贮水量和水分利用效率较秸秆粉碎还田平均增加了6.39%和7.38%。覆膜处理可进一步提高土壤贮水量和水分利用率,增幅分别为10.62%~16.29%、13.88%~18.87%;并增加了土壤养分含量,其中土壤有机碳、全氮、碱解氮、速效磷和速效钾含量分别增加0.70%~8.03%、1.63%~8.01%、7.75%~13.86%、9.19%~40.48%和4.06%~10.62%。与秸秆还田或覆膜相比,秸秆还田结合覆膜处理的干物质量和产量分别增加3.10%~15.35%、11.02%~17.08%,1.84%~12.81%、8.94%~14.83%;其中秸秆发酵还田增加最多,平均为12.04%和10.08%。【结论】秸秆还田和覆膜通过调控土壤水分和养分,提升了土壤供水供肥能力,进而促进作物干物质积累量和产量的同步增长。其中秸秆发酵还田(MFS)效果优于粉碎还田(MS),有利于春玉米抗旱、增肥、增效和高产。
