Pecan cultivation: general aspects

ABSTRACT: Given the increasing investment in the pecan production in southern Brazil, it becomes necessary researches, assisting in solve problems and proposition of technical and methodology to enhance this production chain. Thus, the present review aimed to survey the existing information about the culture, both on the world and the Brazilian scene. Issues related to botany, climate and soil requirements, alignment and planting density, cultivars, pests and diseases, among other technical aspects of this culture will be addressed. Pecan nut presents nutraceutical properties that are beneficial to human health, which has increased its demand from consumers. However, there are few research results with pecan nut in Brazil and there are many gaps in scientific knowledge about this culture, especially as regards the management of pests and diseases control, irrigation and nutrition, in Brazilian conditions.摘要：伴随巴西南部碧根果（pecan）产业投入的持续增长，开展相关研究以助力破解产业难题、提出技术方案与优化路径以完善该产业链已成为必要之举。为此，本综述旨在全面梳理全球及巴西境内有关该作物的现有研究资料。本文将涵盖该作物的植物学特性、气候与土壤要求、定植配置与种植密度、栽培品种、病虫害防控等多项核心技术内容。碧根果（pecan nut）具备有益于人体健康的营养保健属性，这推动了消费者对其需求量的持续攀升。然而，当前巴西境内针对碧根果的研究成果相对匮乏，且在巴西本土种植条件下，该作物的相关科学认知仍存在大量空白，尤其集中于病虫害防控管理、灌溉技术与养分管理等关键领域。
