西班牙Estepa地区橄榄树状况的简要报告

 2023-08-24     已有1人浏览


Conclusion: In general, terms, the new crop is developing well without significant incident of pest or weather  conditions. The olive groves present a healthy situation but poor amount of olive fruits. The fruits are  developing without any affected pest like fly, etc. The olive trees are starting to present some hydric stress that could affect to the fruits. The  humidity of the soil is enough for the current develop of fruits by now and supporting the  summer. The temperatures and weather conditions are the usual for this period of the year although we  are reaching to some peaks of temperature of 45ºC. These heat waves were not so many days  therefore the incident in the trees was not very significant.  In addition, I must mentioned that this summer we had a good thermal amplitude between day  and night, this gives a rest to the tree during the nights.

Going around the area, we can find some farms with very healthy fruits in a good develop. In  the other hands, others farms present shortage of water with the wrinkled fruits. As well, other  farms present small and short developed fruits. Regarding to maturity of the fruits; the fruits show better maturity than previous season; some  of them present a yield of 11% at the beginning of August. It seems to be that harvest will start  earlier this season due the advanced maturity of fruits. Below some pictures took on date 20th August 2023.  The pictures were taken in new frame farms (intense farms) , old frame farms and super intense  farms.  The farms with irrigation systems present better-developed fruits with better sizes, those farms  without irrigation present poor fruits.  In general, all farms present poor amount of olive fruits on the trees.

结论:总体而言,新作物发育良好,没有发生重大病虫害和气候条件的影响。橄榄园呈现健康状况,但橄榄果实数量不足。果实正在发育,没有苍蝇等害虫的影响。橄榄树开始出现一些可能影响果实的水分胁迫。土壤的湿度足以满足目前水果的发育,并支持夏季。气温和天气状况在一年中这个时期是正常的,尽管我们达到了45ºC的一些峰值。这些热浪没有那么多天,因此在树上的事件不是很重要。另外,我必须提到的是,今年夏天我们有一个很好的昼夜热振幅,这给了树在晚上休息。在这个地区四处走走,我们可以找到一些种植着健康水果的农场。

另一方面,其他农场用皱巴巴的水果来表示缺水。同样,其他农场也提供小而短的水果。关于果实的成熟;果实比前一季更成熟。由于果实的成熟期较早,本季节的收获预计会提前。以下是2023年8月20日拍摄的一些照片。照片是在新框架农场(密集农场),旧框架农场和超级密集农场拍摄的。有灌溉系统的农场果实发育较好,尺寸较大,没有灌溉系统的农场果实质量较差。总的来说,所有农场的橄榄树果实数量都很低。
