新建草坪要铺多厚的土？

在整理好的基土上铺 10–15 厘米优质种植土。低于 10 厘米干得很快，第一波高温草就会受损。铺土前先把基土松开。

一立方码种植土有多重？

干土约 2,000–2,200 磅，湿土可达 2,700 磅，大致相当于每立方码一吨。用手推车搬运前值得先算清楚。

一立方码等于多少袋？

按常见的 0.75 立方英尺规格约为 36 袋。超过十袋左右，即使算上运费，散装通常也更便宜。

种植土和营养土有什么区别？

种植土是筛分过的天然土壤，属于基础材料；营养土掺入了堆肥和改良剂。高床菜园只用种植土会导致基质过密、排水不良。

新土要和原土混合吗？

铺土前把表层松开即可，不必深翻。新土与压实基土之间形成明显分层会阻挡根系和水分，这正是新草坪长不好的常见原因。

体积 yd³ = 长 × 宽 × (厚 in ÷ 12) ÷ 27   ·   重量 = ft³ × 密度

参考资料

Measure what the tool asks for
This calculator works from 长度 in ft, 宽度 in ft and 厚度 in in. Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
体积 yd³ = 长 × 宽 × (厚 in ÷ 12) ÷ 27 · 重量 = ft³ × 密度 Every figure on the page comes out of that one expression, so you can check it by hand.
Choosing a 土壤状态
提示：湿土同体积可重出 25%。雨后按吨采购，等于在为水付钱。
Where the numbers come from
The constants are taken from USDA NRCS Soil Health — Soil bulk density guidance and ASTM D5268 — Standard Specification for Topsoil, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.

把长、宽、厚（英尺）相乘再除以 27 得立方码。6 × 3 米的区域铺 15 厘米约需 3.7 立方码。
