    美农8月12日对产量的预估可能会发生很大变化

      美国农业部将于8月12日发布今年第一份以调查为基础的收成预测。到目前为止,生产前景还只是猜测,因此政府的数据将最终提供一些更有力的证据,证明农民们在田地里种了些什么。但历史告诫人们不要爱上这些预测,到一月份最后一次生产数据公布的时候,它们可能看起来完全不同了。

      我自己的“猜测”是玉米产量为每英亩176.7蒲式耳,大豆产量为51.3bpa。在深入研究产生这些估计的机制之前,值得注意的是一年前发生的事情。我用于预测的模型在2020年8月的预测范围为178.4到184 bpa,美国农业部的预测范围为181.8 bpa。五个月后,玉米产量只有172 bpa,附近的玉米价格从未低于5美元。

      大豆的产量变小了

      美国农业部一年前对大豆的预测也是悲观的,高达53.3 bpa。报告发布前,我的模型范围在50.4到55.1 bpa之间,而美国农业部一月份的产量一路下降到50.2。同样的,或许更多的不确定性存在于今年,因为一个不寻常的生长季节走向终点。为什么会有这样的疑虑?除了西北部玉米地带的干旱,八月的天气可能再次变得重要。一年前,美国农业部早期的乐观情绪被干旱转变的开始所削弱,而干旱已经演变成一些种植者今年的全面灾难。我使用各种技术来估计产量。其中大多数年份的数据都是“正确”的,尽管去年玉米的数据并非如此。

      对于玉米来说,自2006年以来最准确的方法是农场期货自己对农民的调查,这要到本周晚些时候才能公布。紧随其后的是基于每周全国农作物收视率的预测,紧随其后的是逐州分析。根据天气和植被健康指数做出的估计显示准确性较低,但是所有这些占了美国农业部8月份实际数字(所谓的r平方)的差异超过85%。农业期货调查也是预测美国农业部八月份大豆产量最准确的方法,其次是天气、作物评级和VHI。

      收益率看起来“正常”

      那么,2021年的模型预测如何呢?在范围的低端是170.4 bpa生产的VHI模型。农作物的等级稍高一些,州和全国的等级分别为172.3和174.4 bpa。另一个极端是天气模型,高达184.9 bpa。但是这个数字说明了在如此早的时候做出预测的一些困难。它基于7月份关键玉米种植州的初步平均气温和降雨量,使用的测量读数通常会在最终数据清理和公布时发生变化。使用卫星地图部分估算的降雨量将把产量降低到179.1 bpa。

      这些农作物进度等级也可以微调。我的评级模型将收益率与去年秋天公布的最终评级进行比较。从8月第一周开始,利用评级进行历史性的预测,将收益率估计提高到179%。把所有这些预测结果加起来,我的总体估计是176.7 bpa,比统计学上的“正常”产量少了一蒲式耳。

      美国农业部的结果各不相同

      由于大豆是在8月份生产的,因此大豆估计还有更多的惊喜可能。我把下个月的最新预测数据输入到我的估算中,根据7月份的初步天气数据得出的结果是51.3 bpa。依靠7月的卫星降雨量,这个数字略微减少到51.1。与广泛的玉米估计不同,大豆的变化较小。VHI模型得出的指数最低,为50.6 bpa,国家农作物评级为51,国家条件为52.1。在8月的第一周,利用历史评级将这一数据下调至51.9 bpa,所有这些结果的平均值为51.3。这与用20年趋势产量估计的“正常”作物产量非常接近。

      当所有这些都在一月份说完并完成时,美国农业部八月份的预测对玉米和大豆都是相当有利的。只有天气模型更准确,但正如去年所显示的那样,政府的数字也可能出现偏差,有时偏差很大。事实上很难预测2021年1月份的最终产量预测结果。自1965年以来,玉米产量从8月25日开始下降,增长了30倍,并保持了一次不变。大豆产量下降了23倍,上升了31倍,两次保持不变。这些差异都不足以达到统计上的显著性,这意味着没有明确的趋势。这表明关于2021年粮食产量的争论远未结束,历史表明这才刚刚开始。(编译:农产品集购网)
