alkaline soil 的音标是[ə'kælɪn] ['səʊl] ，含义是呈碱性的土壤；发音分别是 ['ælkəlin] 和 ['səʊl] 。使用方法是：当作为名词时，意思是含钾灰石或石膏的土壤，通常有足够的石膏或含碱矿物使土壤呈碱性；当作为形容词时，意思是碱性的。记法可以用谐音记忆，“爱哭林”发音类似“爱哭淋”，表示碱性土壤容易淋湿。
碱性土壤的物理现象有：
土色白且无生机 。碱性土壤一般呈现灰白色，土壤中的有机物含量低，土壤质地松散，土壤颜色贫瘠，很难长出植物。
含水量低 。此类土壤通常偏硬，其保水能力比酸性土要差。

Alkaline Soil Management: A Practical Guide
Introduction
Alkaline soil is a common problem in many parts of the world, particularly in regions with high altitudes, alkaline water sources, or high levels of fertilizer usage. Alkaline soil can affect plant growth and crop yields, leading to decreased crop quality and yield. Therefore, it is essential to understand alkaline soil management techniques to ensure optimal plant growth and yield.
I. Soil Analysis and pH Testing
The first step in alkaline soil management is to conduct a soil analysis and pH testing. This will help determine the specific pH level of the soil and identify any other nutrients that may be lacking. pH meters can be used to test the soil pH level, and soil amendments such as lime or sulfur can be used to adjust the pH level to a more suitable range for plant growth.
II. Amending the Soil with Lime or Sulfur
Once the pH level has been determined, it is necessary to add amendments to the soil to adjust its pH. Lime is commonly used to raise the pH level of alkaline soil, while sulfur can be used to lower the pH level of acidic soil. The type of amendment used should be based on the specific needs of the plants and the soil type.
III. Water Management
Water management is crucial for alkaline soil management. Waterlogging or excessive watering can increase the pH level of the soil, leading to plant stress and reduced yields. Therefore, it is essential to monitor water usage and ensure that plants receive sufficient water but not too much.
IV. Fertilizer Management
Fertilizer management is also crucial for alkaline soil management. High pH levels can lead to fertilizer runoff and leaching, reducing its effectiveness. Therefore, it is essential to use slow-release fertilizers or fertilizers that are designed for alkaline soils. Additionally, it is important to monitor fertilizer usage and adjust it based on the needs of the plants and the soil type.
V. Plant Selection
Finally, it is essential to select plants that are suitable for alkaline soil conditions. Some plants are more tolerant of alkaline soils than others, and selecting these plants can help maximize yields and minimize stress on plants.
Conclusion
Alkaline soil management is essential for ensuring optimal plant growth and yield. By conducting a soil analysis and pH testing, adjusting the pH level with lime or sulfur, managing water usage, using slow-release fertilizers, selecting appropriate plants, and implementing other management techniques, alkaline soil can be managed effectively to achieve optimal plant growth and yield.
