摘要

红树林沼泽水稻生产(MSRP)是指在经过人为改造的前红树林土壤上种植水稻,用于粮食生产。这种方法尽可能利用淡水的最大储存量来淡化土壤,使其具有生产力。然而,降雨模式的时空变化会导致生产效率下降,影响作物生长并降低生产力。为了提高管理系统更新项目的效率,有必要找出与盐度有关的主要制约因素,提高淡水储存效率和水的生产力,并使之最大化。本研究对几内亚比绍北部和南部地区的 MSRP 系统进行了总体描述,旨在确定水资源管理的主要限制因素。在描述中使用了类型学方法,并确定了水稻田内具有特定特征的区域。此外,本综述还分析了与盐度问题有关的土壤理化特征,介绍了农艺管理、水稻品种以及管理堤坝和堤岸对改善红树林沼泽水稻水管理的意义。这项研究表明,红树林沼泽水稻生产系统具有动态性和复杂性的特点,涉及与盐度特征、文化影响和小气候条件相关的各种制约因素,而这些因素又受时间变化的影响。

The Mangrove Swamp Rice Production System of Guinea Bissau: Identification of the Main Constraints Associated with Soil Salinity and Rainfall Variability
Mangrove swamp rice production (MSRP) refers to rice cultivation in former mangrove soils that have been anthropogenically modified for food production. The method utilizes the largest possible storage of fresh water to desalinate the soils and make them productive. However, temporal variability in rainfall patterns causes loss of efficiency in production, impacting crop growth and reducing productivity. To improve MSRP, it is necessary to identify the primary constraints associated with salinity, enhancing and maximizing freshwater storage efficiency and water productivity. This study provides a general description of the MSRP system in both the northern and southern regions of Guinea-Bissau, aiming at the identification of the main water management limitations. The description involves the use of typologies and the identification of zones with specific characteristics within the paddies. Furthermore, this review includes an analysis of the physicochemical characteristics of soils in relation to salinity issues, descriptions of agronomic management, rice varieties, and the significance of managing dikes and bunds to improve mangrove swamp rice water management. This study shows how the MSRPS is characterized by dynamism and complexity, involving a wide range of constraints associated with salinity features, cultural influences, and microclimatic conditions that are subject to temporal variations.
