摘要
为探究微喷灌水肥一体化设备在农田中的应用效果,该文以玉米种植为试验对象,分析该设备在土壤含水率、土壤呼吸速率、土壤贮水量、土壤水分利用效率,以及玉米产量的影响,通过对比传统灌溉施肥方式与微喷灌水肥一体化系统开展3年定位试验。结果表明,微喷灌水肥一体化系统能有效提高土壤含水率与贮水能力,降低土壤呼吸速率波动,改善土壤水分与养分分布状况,显著提升水肥利用效率。与传统灌溉施肥方式相比,该设备处理下玉米的单位面积产量提高15%,因此,微喷灌水肥一体化技术具有显著的节水、省肥、增产效果,适合在玉米种植区推广应用,具有良好的生态和经济效益。
In order to explore the application effect of micro-sprinkler irrigation and water-fertilizer integration equipment in farmland,this article takes corn planting as the test object,analyzes the impact of this equipment in soil water content,soil respiration rate,soil water storage capacity and soil water use efficiency of nutrients and corn yield,and by comparing the traditional irrigation and fertilization methods with the measured data of micro-sprinkler irrigation and water-fertilizer integration system in field,the results show that:micro-sprinkler irrigation and water-fertilizer integration system The results showed that micro-sprinkler irrigation water-fertiliser integration system can effectively increase soil water content and water storage capacity,reduce soil respiration rate fluctuations,improve soil water and nutrient distribution,and significantly improve water and fertiliser use efficiency.Compared with the traditional irrigation and fertiliser application methods,the unit area yield of maize under the treatment of this equipment is increased by 15%,therefore,the micro-sprinkler irrigation water-fertiliser integration technology has a significant effect of water saving,fertiliser saving and yield increasing,and is suitable for popularising and applying in maize planting areas,which has good ecological and economic benefits.
