摘要

摘要目前,灌溉用水不足是降低园艺作物产量和生产力的关键因素。灌溉用水的严重短缺需要改进我们的灌溉方法和灌溉管理技术。“在灌溉用水有限的情况下,最大限度地提高作物产量的一种可能方法是城市灌溉,其中一种不足灌溉方式是部分根区干燥”。因此,本综述的目的是评估部分根区干旱对土壤含水量、植物生理、水分吸收、运动及其利用效率的影响,并提出叶绿素荧光在部分根区枯死灌溉管理中的作用。不同研究结果表明,部分根区干旱灌溉通过将根区干旱部分吸收的水分补偿到湿润部分,并交替灌溉或重新湿润,来保持土壤水分的减少和灌溉吸水。当我们使用部分根区干燥灌溉时,ABA介导的水通道蛋白活性增加,这反过来又增加了水向上进入茎和叶的运动。这种情况发生在湿区和干燥区。部分根区干旱灌溉在缺水年份可节省518 m3 ha−1灌溉用水,灌溉用水效率提高70%,与全灌溉相比仅减产10%。叶绿素荧光可能有助于早期检测植物水分胁迫,并最终帮助制定部分根区干旱灌溉的灌溉计划。总的来说,这篇综述强调了部分根区干燥灌溉的一些重要性,并提出了主要管理叶绿素荧光的方法。

Review: partial root zone drying an approach to increase water use efficiency of horticultural crops and chlorophyll fluorescence
Abstract Nowadays, lack of irrigation water is critical factor that reduce horticultural crop production and productivity. This serious shortage of irrigation water requires improvement of our irrigation methods and irrigation management techniques. “One of the possible methods to maximize crop production with limited irrigation water was deficit irrigation one way of deficit irrigation was partial rootzone drying”. Therefore, the objective of the review was to assess impact of partial root zone drying on soil water content, and physiology of plants mainly, water absorption, movement, its use efficiency by plants and to suggest role chlorophyll fluorescence on partial root zone dying irrigation management. Result of different studies showed that partial rootzone drying irrigation preserve soil moisture lessening and irrigation water absorption by compensating water absorbed from dry part of the root zone to the wetter part and dry part is irrigated or rewetted alternatively. When we use partial root-zone drying irrigation ABA mediated aquaporin activity increases, which in turn increase the movement of water upward in to stem and leaf. This occurs in both the wet to dried zones. Partial rootzone drying irrigation saves 518 m3 ha−1 irrigation water in moisture deficit year and increase irrigation water use efficiency by 70%, and it reduce grain yield by only 10% compared to full irrigation. Chlorophyll fluorescence may help in early detection of plant water stress and ultimately to irrigation scheduling o f partial rootzone drying irrigation. Generally, this review highlights some importance of partial rootzone drying irrigation and suggests methods to manage it mainly chlorophyll fluorescence.
