The authors analyzed certain species and varieties of fruit tree in which applied crop technology is used and also undergoes the effects of climate change. The aim is to extend productive crop varieties, resistant to disease and pests, in order to obtain superior yields. The research was conducted in orchards located in northwestern Romania (on 8.59 ha), intensively cultivated with apple, plum, and almond species. The blooming period of the species and fruit production was studied in 2009, the first year of the farm's commercial production, and then compared to figures from 2016 to see the changes that occurred. Climatic conditions were studied throughout the period of existence of the farm (2002-2016). To determine the influence of the climatic factor on the blooming and production periods, respectively, every year is considered having pre-blooming, blooming, and ripening periods. It was found that climate change influences the annual biological cycle of the trees: the vegetative rest period of the trees shortens, the tree vegetation begins earlier in the spring, and the blooming period is advanced by as much as 10 days compared to normal cultivated varieties. All these factors have direct repercussions on the quantity of production.
作者分析了某些经过作物技术应用和气候变化影响的果树品种和变种。其目的是延长生产性作物品种的生长期,使其具有抗病虫害的能力,从而获得更高的产量。研究在罗马尼亚西北部(占地 8.59 公顷)的果园进行,这些果园集中种植苹果、李子和杏仁等品种。研究人员研究了这些物种的开花期和果实产量,在 2009 年,也就是该农场商业生产的第一年进行了研究,并与 2016 年的数据进行了比较,以观察发生的变化。在农场存在的整个期间(2002-2016 年)都对气候条件进行了研究。为了确定气候因素对开花期和结果期的影响,每年都被认为有预开花期、开花期和成熟期。结果发现,气候变化影响了树木的年度生物周期:树木的营养休眠期缩短,树木的植被在春季更早开始,开花期比正常栽培品种提前了多达 10 天。所有这些因素都对产量产生直接影响。
