使用说明与常见问题How-to & FAQ

「土壤/花园用土量计算器」是什么？What is the Soil Calculator tool?

计算花坛、菜畦或容器需要多少土壤/堆肥：按长 × 宽 × 深求体积，给出立方英尺、立方码、升和立方米，并按袋装容量换算所需袋数。支持英制（ft/in）和公制（m/cm）。Work out how much soil or compost a garden bed, raised bed or container needs: length × width × depth gives the volume in cubic feet, cubic yards, litres and cubic metres, plus the number of bags for a given bag size. Works in feet/inches or metres/centimetres.

如何使用「土壤/花园用土量计算器」？How do I use the Soil Calculator tool?

在「土壤/花园用土量计算器」中，填写「单位」、「长」、「宽」、「深」、「单袋容量（可选）」等参数，结果会随输入实时计算并显示在下方。In the Soil Calculator: Fill in "Units", "Length", "Width", "Depth", "Bag size (optional)"; results are recalculated instantly as you type.

用土量是怎么算的？How is the amount of soil calculated?

体积 = 长 × 宽 × 深。英制下长宽用英尺、深用英寸（自动换算为英尺），结果以立方英尺为主；公制下长宽用米、深用厘米。1 立方码 = 27 立方英尺，常用于散装土方。Volume = length × width × depth. In imperial, length and width are in feet and depth in inches (converted to feet), giving cubic feet; in metric, length and width are in metres and depth in centimetres. 1 cubic yard = 27 cubic feet, common for bulk soil.

需要多少袋？How many bags do I need?

填入单袋容量（立方英尺或升）后，用总体积除以单袋容量并向上取整。常见袋装为 1.5 ft³、2 ft³ 或 40 L、50 L。散装土方通常按立方码或立方米购买。Enter the bag size (cubic feet or litres) and the total volume is divided by it and rounded up. Common bags are 1.5 ft³, 2 ft³, 40 L or 50 L. Bulk soil is usually sold by the cubic yard or cubic metre.

花坛深度该填多少？What depth should I use for a bed?

一般草花和蔬菜根系需要 15–30 cm（6–12 in）土壤，抬高苗床常填 30 cm 以上，草坪铺土 5–10 cm。按你的作物和容器深度填写即可。Most flowers and vegetables need 15–30 cm (6–12 in) of soil; raised beds are often filled 30 cm or more, and top-dressing a lawn uses 5–10 cm. Enter the depth your plants or container need.

不规则形状怎么估算？How do I estimate an irregular shape?

可把区域拆成几个矩形分别计算再相加，或用能覆盖该区域的最小矩形估算（会略多）。圆形花坛可用 面积 = π × 半径² 先求面积，再乘以深度。Split the area into rectangles, work out each and add them, or use the smallest rectangle that covers the area (a slight over-estimate). For a round bed, find the area with π × radius² first, then multiply by the depth.
