西班牙Estepa地區(qū)橄欖樹狀況的簡要報(bào)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(jié)論:總體而言,新作物發(fā)育良好,沒有發(fā)生重大病蟲害和氣候條件的影響。橄欖園呈現(xiàn)健康狀況,但橄欖果實(shí)數(shù)量不足。果實(shí)正在發(fā)育,沒有蒼蠅等害蟲的影響。橄欖樹開始出現(xiàn)一些可能影響果實(shí)的水分脅迫。土壤的濕度足以滿足目前水果的發(fā)育,并支持夏季。氣溫和天氣狀況在一年中這個時期是正常的,盡管我們達(dá)到了45oC的一些峰值。這些熱浪沒有那么多天,因此在樹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很好的晝夜熱振幅,這給了樹在晚上休息。在這個地區(qū)四處走走,我們可以找到一些種植著健康水果的農(nóng)場。
另一方面,其他農(nóng)場用皺巴巴的水果來表示缺水。同樣,其他農(nóng)場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(jié)的收獲預(yù)計(jì)會提前。以下是2023年8月20日拍攝的一些照片。照片是在新框架農(nóng)場(密集農(nóng)場),舊框架農(nóng)場和超級密集農(nóng)場拍攝的。有灌溉系統(tǒng)的農(nóng)場果實(shí)發(fā)育較好,尺寸較大,沒有灌溉系統(tǒng)的農(nóng)場果實(shí)質(zhì)量較差。總的來說,所有農(nóng)場的橄欖樹果實(shí)數(shù)量都很低。
