西班牙Estepa地區橄欖樹(shù)狀況的簡(jiǎn)要報告

 2023-08-24     已有1人瀏覽


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.

結論:總體而言,新作物發(fā)育良好,沒(méi)有發(fā)生重大病蟲(chóng)害和氣候條件的影響。橄欖園呈現健康狀況,但橄欖果實(shí)數量不足。果實(shí)正在發(fā)育,沒(méi)有蒼蠅等害蟲(chóng)的影響。橄欖樹(shù)開(kāi)始出現一些可能影響果實(shí)的水分脅迫。土壤的濕度足以滿(mǎn)足目前水果的發(fā)育,并支持夏季。氣溫和天氣狀況在一年中這個(gè)時(shí)期是正常的,盡管我們達到了45oC的一些峰值。這些熱浪沒(méi)有那么多天,因此在樹(shù)上的事件不是很重要。另外,我必須提到的是,今年夏天我們有一個(gè)很好的晝夜熱振幅,這給了樹(shù)在晚上休息。在這個(gè)地區四處走走,我們可以找到一些種植著(zhù)健康水果的農場(chǎng)。

另一方面,其他農場(chǎng)用皺巴巴的水果來(lái)表示缺水。同樣,其他農場(chǎng)也提供小而短的水果。關(guān)于果實(shí)的成熟;果實(shí)比前一季更成熟。由于果實(shí)的成熟期較早,本季節的收獲預計會(huì )提前。以下是2023年8月20日拍攝的一些照片。照片是在新框架農場(chǎng)(密集農場(chǎng)),舊框架農場(chǎng)和超級密集農場(chǎng)拍攝的。有灌溉系統的農場(chǎng)果實(shí)發(fā)育較好,尺寸較大,沒(méi)有灌溉系統的農場(chǎng)果實(shí)質(zhì)量較差??偟膩?lái)說(shuō),所有農場(chǎng)的橄欖樹(shù)果實(shí)數量都很低。
