摘要
针对水稻栽培中的水资源管理问题,介绍了水稻栽培水分需求分析,以及全球水资源状况和水稻生产所面临的挑战;阐述了节水灌溉技术在水稻生产中的应用,分析了各种技术的优缺点和适用条件;探讨了土壤水分管理和种植方式对水稻产量和水分利用效率的影响;最后总结水稻栽培中的新技术,如精准灌溉、土壤墒情监测、农业遥感等,这些技术可以帮助农户更加科学地管理水资源,提高水稻产量和水分利用效率。合理的水资源管理对水稻生产至关重要,必须采取多种措施来保障水稻的生长和发展。
This paper provides an overview of water management issues in rice cultivation.Firstly,an analysis of water demand for rice cultivation is presented,as well as the global water resources situation and the challenges faced by rice production.Then,the application of water-saving irrigation technologies in rice production,including rainwater harvesting,soakaway irrigation,drip irrigation,and micro-sprinkler irrigation,is described,and the advantages,disadvantages,and applicability conditions of each technology are analyzed.Then,the effects of soil moisture management and planting methods on rice yield and water use efficiency are discussed,including the principles of moisture management,determination of irrigation volume,selection of irrigation timing,and improvement of irrigation methods.Finally,some new technologies in rice cultivation,such as precision irrigation,soil moisture monitoring,and agricultural remote sensing,are introduced,which can help farmers manage water resources more scientifically and improve rice yield and water use efficiency.Rational water resource management is crucial for rice production,and various measures must be taken to ensure the growth and development of rice.
