任何园艺家,无论是专业的还是新手,都会同意知道如何测量花园和后院土壤的pH值是非常重要的。 否则,您怎么知道哪些水果、蔬菜和花卉您可以种植(如果您尝试种植,哪些一定会死)?

如果您不知道什么是pH值,请了解土壤pH值(潜在氢)测试是为了了解土壤中的氢离子含量。 如果pH值低于7,则被认为是酸性土壤。 完美的7是中性,而高于7则被认为是碱性土壤。

不过不用担心,被认为是酸性或碱性的土壤并不一定是坏事--这完全取决于您打算用它来做什么。 幸运的是,大多数植物都能完全适应pH值在6至7.5之间的土壤。

因此,如果您想在花园里种植一些特定的植物,您就需要尽快了解土壤的pH值。 但是,如果您没有土壤pH计来帮助您测试土壤的酸碱性,您该怎么办呢? 您只需参考我们的指南,其中详细介绍了如何在家中测量土壤的pH值。 见下文。

第一步:收集工具

无论您是要种植新的花圃,还是要种植对pH值有特殊要求的新品种,测试土壤pH值始终是个好主意。 一些专业人士甚至建议您每隔几年测试一次土壤(如果您过去曾对土壤进行过改良,这一点尤为重要)。

这是因为用于调节土壤pH值的材料,如元素硫和石灰,会随着时间的推移而分解。 因此,可能有必要添加一些新材料,以帮助保持土壤pH值在最佳水平。

如果您的花园土壤pH值已经很好,我们仍然建议添加有机堆肥、泥炭或其他有机材料,以帮助改善土壤质地和营养价值。

步骤2:采集土壤样品

用勺子或园艺铲将一些土壤放入一个干净的塑料容器中。 为达到最佳效果,将您想种植的同一空间(花园/地块)的一些土壤样本混合在一起。

例如,如果您对松树丛附近的土壤进行检测,可能会得到非典型酸性结果,因为松针会增加土壤的酸度。

步骤3:测试土壤碱度

将土壤样品放入盆中后,加入约1/2杯水。 用勺子搅拌样品,使其慢慢变成泥浆。

步骤4:加醋

在泥浆混合物中加入1/2杯醋。 如果土壤样品开始冒泡或起泡,则可以确定其pH值为碱性。 起泡越明显,pH值越高。

提示:由于大多数土壤已经具有微酸性,该测试的任何反应都将显示土壤呈碱性,因此您可能需要对土壤进行改良,使pH值更适合大多数植物生长。

步骤5:测试土壤的酸度

想知道如何测量酸性土壤的pH值吗? 然后,在另一个干净的容器中再取一份土壤样品。 加入半杯水,搅拌成另一种泥状混合物。

第六步:加入小苏打

现在,不要加醋,而是在泥浆混合物中加入约半杯小苏打。 如果出现气泡或起泡,则表明土壤呈酸性。

然而,强烈的反应可能表明土壤中的酸性水平极高。

最好的办法是:改良土壤以提高土壤的pH值,或者改种能在酸性土壤中生长的植物。

第7步:必要时更换土壤

当然,土壤过酸或过碱并不是世界末日(或您的园艺计划)。幸运的是,通过添加某些天然材料可以改变土壤pH值。

例如,添加木灰或农用石灰可提高土壤的pH值,使其碱性更强而酸性更弱。 而松针、硫酸铝和硫则有助于降低土壤pH值。

测试土壤pH值的技巧

  • 如果您用醋和碳酸氢钠测试土壤,但都没有产生气泡或泡沫,也不要紧张。 这可能意味着您的土壤是完全中性的,无需进一步测试。
  • 对于非常大的花园和庭院,最好分别测试几个土壤样本,而不是将所有样本合并为一个样本(对于较小的花园和庭院可能会这样做)。
  • 如果您的土壤无法种植任何植物,我们建议您将土壤样本送至实验室(您需要支付一定的费用),以便专业人员帮助您的园艺计划重回正轨。
  • 例如,蓝莓和绣球花可在酸性土壤中茁壮成长,而芦笋、甜菜根和观赏三叶草则更喜欢碱性土壤。
