【摘要】 桂南和桂东南芒果生产是广西芒果产业的重要组成部分，近年来芒果种植面积不断扩大，产量稳步增长，果品质量和生产效益持续提升。深入了解该地区芒果产业的现状特别对其存在问题的研究有助于扬长避短，促进该地区芒果产业健康发展。本研究调研了近10年桂南和桂东南芒果产业的发展状况，包括产业概况、果园立地条件、土壤质地、种植规模、种植品种、种植密度、上市时间及栽培表现等，发现当前该地区芒果产业发展具有单产高的优势；同一品种的芒果通常比广西芒果主产区右江河谷的晚熟10～15 d，有利于错开收获时间提高经济效益；芒果树的生长发育状况良好，未出现因过度使用生长调节剂导致大量无胚果实的现象，也没有过量使用果实拉长膨大剂人为促进果实生长以追求高产量的现象。存在的主要问题是政府部门重视程度不足，缺乏有效组织；适种区域界定不明确，易受不良天气影响；芒果生产的关键栽培技术普及率低；提早采收现象普遍，未能充分发挥晚熟优势。针对存在问题提出如下对策建议：科学划分适种区和非适种区；组建芒果产业科技研发团队，持续开展适配栽培技术研究、示范及推广；加强品种结构调整，积极推广中晚熟品种，提升中晚熟品种的种植比例；倡导合理使用生长调节剂及膨大剂，减少无胚果的数量；推广省工省力栽培技术，加大技术培训力度，提高果农的生产技术水平。更多还原

【Abstract】 Mango production in southern and southeastern Guangxi is an important part of the Guangxi mango industry,with expanding of planting area,increasing yield and improving fruit quality and production benefits in recent years. A deep understanding of the current state of the mango industry in this region,especially its problems,will help promote its healthy development.The study investigated the development of mango industry in southern and southeastern Guangxi in recent 10 years,including industrial overview,orchard site conditions,soil texture,plantation scale,planting varieties and densities,sales period and cultivation performance,etc. The mango industry in this region has several advantages. These include a high yield per unit area;a later ripening period—typically 10 to 15 days after mangoes in the Youjiang River Valley(a major production area in Guangxi)—which helps stagger the harvest and improve economic efficiency;and healthy tree growth without the excessive use of growth regulators that cause seedless fruits,or elongation agents used to artificially boost yield. The main challenges include inadequate attention from government departments and ineffective organizational support;unclear delineation of planting zones,which exposes the crops to adverse weather in unsuitable areas;low adoption rates of essential mango cultivation techniques;and the widespread practice of early harvesting,which undermines the full potential of late-maturing varieties. To address these problems,the following countermeasures are proposed:scientifically delineate suitable and unsuitable planting areas;establish a dedicated research and development team to conduct studies,demonstrations,and promotion of appropriate cultivation techniques;optimize the varietal structure by promoting mid-and late-maturing mango varieties and increasing their planting proportion;advocate for the rational and controlled use of growth regulators and fruit expansion agents to reduce the occurrence of seedless fruits;demonstrate and promote labor-saving cultivation methods;and enhance technical training programs to improve farmers’ production skills.更多还原
