Desert truffles have become an alternative agricultural crop in semiarid areas of the Iberian Peninsula due to their much appreciated edible value and their low water requirements for cultivation. Although most studies related to desert truffle production point to the sole importance of precipitation, this work is the first systematic study carried out to characterize whether other important agroclimatic parameters, for example reference evapotranspiration, soil water potential, relative air humidity %, aridity index or air vapour pressure deficit, may have an impact on a desert truffle production in an orchard with mycorrhizal plants of Helianthemum almeriense × Terfezia claveryi for 15 years from the plantation. The results show for the first time that T. claveryi production has two key periods, during its annual cycle: autumn (September to October) and spring (end of March). The aridity index and soil water potential seem to be the most manageable parameters in the field and can be easily controlled by applying irrigation during the abovementioned periods. Agroclimatic parameters can influence the final crop a long time before the desert truffle fruiting season contrary to what happens with other edible mycorrhizal mushrooms. Four different models to manage desert truffle plantations are proposed based on these agroclimatic parameters in order to optimize and stabilize carpophore fructifications over the years.

在两个关键的年度期间，沙漠松露的农作物取决于农业气候参数

由于伊比利亚半岛半干旱地区的沙漠松露具有很高的食用价值和耕种所需的低水量，它们已成为伊比利亚半岛半干旱地区的替代农作物。尽管大多数与沙漠松露生产有关的研究都指出降水是唯一的重要性，但这项工作是进行的第一个系统研究，目的是表征其他重要的农业气候参数，例如参考蒸散量，土壤水势，相对空气湿度％，干旱指数或空气水汽压差，可能对一个沙漠松露生产在果园与菌根植物产生影响almeriense半日× Terfezia claveryi用于从种植园15年。结果首次显示了克拉维酵母在其年度周期中，生产有两个关键时期：秋季（9月至10月）和春季（3月底）。干旱指数和土壤水势似乎是该领域中最可管理的参数，并且在上述期间可以通过灌溉来轻松控制。与其他可食用菌根蘑菇不同，农业气候参数会在沙漠松露结果季节之前很长时间影响最终作物。在这些农业气候参数的基础上，提出了四种不同的沙漠松露人工林管理模型，以优化和稳定多年生的oph果结构。
