摘要

预计到2050年世界人口将超过90亿,因此增加粮食生产势在必行。因此,智能农业技术的发展是一个重要的关键粮食生产问题。事实上,通过使用无人机(uav),可以创建归一化植被指数(NDVI)地图,可以指示健康和植被活力等因素。在此背景下,本研究旨在评估三个番茄品种(牛肉心,“chucha”和苹果)在铁和锌生物强化工作流程框架下的状态,遵循有机生产模式。在番茄试验田(GPS坐标- 39°41′48.517″N;8°35′45.524″W),在生产周期内进行6次叶面喷施,喷施剂分别为Zitrilon(15%)(0.40和1.20 kg·ha - 1)和Maxiblend(1和4 kg·ha - 1)。NDVI在第一次叶面喷施前7天测定,最大值为0.86(范围从- 1到1)。第3次叶面喷施后,新鲜收获的番茄颜色没有变化(通过分光光度比色仪测定),但叶片中铁和锌含量增加,番茄本身锌含量增加(“chucha”品种除外)。讨论了与其他分析相关的精准农业技术的使用。

Can Precision Agriculture Be Used in the Management of a Fe and Zn Biofortification Workflow in Organic Tomatoes (Lycopersicum esculentum L.)?
It is expected that the population worldwide might exceed 9 billion by 2050, therefore it being imperative to increase food production. As such, the development of smart farming technology is an important key food production issue. In fact, through the use of UAVs (Unmanned Aerial Vehicles), it is possible to create normalized difference vegetation index (NDVI) maps, that can indicate factors, such as health and vegetation vigor. In this context, this study aimed to assess the state of three tomato varieties (beef heart, “chucha”, and apple) in the framework of a biofortification workflow with Fe and Zn, following an organic production mode. In a tomato experimental production field (GPS coordinates—39°41′48.517″ N; 8°35′45.524″ W), six foliar sprayings were carried out during the production cycle, with a mix of Zitrilon (15%) (0.40 and 1.20 kg·ha−1) and Maxiblend (1 and 4 kg·ha−1). NDVI was determined 7 days before the first foliar spraying and showed a maximum of 0.86 (on a scale from −1 to 1). After the 3rd foliar spraying, no changes were detected in the color of freshly harvest tomatoes (assessed through spectrophotometric colorimeter), but an increase of Fe and Zn content was found in the leaves, and of Zn in tomatoes themselves (except in “chucha” variety). The use of precision agriculture techniques in correlation with the other analyses is discussed.
