Abstract

Film mulching technology has attracted much attention as an important means to improve the quality and yield of crops. Straw fiber paper film, due to its fully degradable characteristics, has been applied to the green production of various economic crops. This study explored the possibility of large-scale effective application of paper film mulching in water-saving irrigation paddy fields. Through field experiment, it comprehensively analyzed the rice growth characteristics, rice yield, and nitrogen transfer in soil under paper film mulching conditions, and examined the responses of these variables to different layers of paper film mulching thicknesses. The experimental result showed that one layer of paper film was currently the best mulching thickness for water-saving irrigation paddy fields, which ensured environmental friendliness while improving rice yield. Compared with non-mulching, one layer of paper film can increase rice yield by 20.2 % and ensure the low level of ammonia volatilization flux. At the same time, it offered more cost-effective solution for weed suppression compared to manual weeding. This study provided the reference for green sustainable cultivation of rice and innovatively development of film mulching technology.

覆盖新视野：膜厚控制下水稻生长和氮素转化

地膜覆盖技术作为提高作物品质和产量的重要手段受到广泛关注。秸秆纤维纸膜由于其完全可降解的特性，已被应用于各种经济作物的绿色生产。本研究探讨了纸膜覆盖在节水灌溉水田大规模有效应用的可能性。通过田间试验，综合分析了纸膜覆盖条件下水稻的生长特征、产量和土壤氮素迁移，并考察了这些变量对不同纸膜覆盖厚度的响应。试验结果表明，1层纸膜是目前节水灌溉水田的最佳覆盖厚度，在保证环境友好的同时提高了水稻产量。与不覆盖相比，一层纸膜可使水稻增产20.2 %，且氨挥发通量较低。同时，与人工除草相比，它为杂草抑制提供了更具成本效益的解决方案。本研究为水稻绿色可持续栽培和地膜技术创新发展提供了参考。
