At the turn of the nineteenth century, agriculture in Spain was seen as an empirical know-how that was transmitted from generation to generation through practice. However, at the royal gardens the idea that agriculture was a scientific branch of knowledge was already germinating. Focusing on the two brothers—Claudio (1774–1842) and Esteban (1776–1812) Boutelou—this paper argues that these gardeners, profiting from their positions at the Spanish royal gardens, promoted agronomic development and education. In spite of the importance of the Boutelou family, a five-generation dynasty of gardeners, historiography has paid scant attention to them, as well as to the importance of agronomic travels and their reports. This paper aims at interweaving the boundaries between the history of science, history of agriculture, and gardens and landscape studies. Through the lenses of history of science and the application of Long's conceptual framework of ‘trading zones’ and Baldassarri and Matei's ‘gardens as laboratories’, we focus on the position of the Boutelou brothers in the gardens of the royal estates and the new Sanlúcar acclimatization garden. We then demonstrate how they were influenced by travels abroad and how Arthur Young, a Briton, became their role model. Moreover, we establish a relation between the Boutelou's network of experts and the rise of translations of English and French books and the appearance of the first agricultural teaching manuals in Castilian, often published in the context of agricultural societies. Finally, we show how this was fundamental to the renewal of agronomic practices and education in Spain.

在 19 世纪之交，西班牙的农业被视为一种经验知识，通过实践代代相传。然而，在皇家园林中，农业是科学知识分支的想法已经萌芽。本文着重于克劳迪奥 (1774-1842) 和埃斯特万 (1776-1812) 布特卢两兄弟，认为这些园丁从他们在西班牙皇家花园的职位中获益，促进了农艺发展和教育。尽管五代园丁王朝布特卢家族很重要，但史学很少关注他们，以及农艺旅行和他们的报道的重要性。本文旨在交织科学史、农业史以及园林和景观研究之间的界限。通过科学史的视角，运用朗的“贸易区”概念框架和巴尔达萨里和马泰的“花园作为实验室”，我们关注布特卢兄弟在皇家庄园花园中的地位和新的桑卢卡尔驯化花园。然后，我们展示了他们如何受到国外旅行的影响，以及英国人 Arthur Young 如何成为他们的榜样。此外，我们在 Boutelou 的专家网络与英语和法语书籍翻译的兴起以及卡斯蒂利亚语的第一本农业教学手册的出现之间建立了联系，这些手册通常在农业社会的背景下出版。最后，我们展示了这对西班牙农艺实践和教育的更新至关重要。
