上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)(shui)石(shi)(shi)的實質是碳酸鈣苔(tai)蘚(xian)植(zhi)物化(hua)石(shi)(shi),暄(xuan)而又脆,良好的吸(xi)水(shui)(shui)(shui)(shui)(shui)石(shi)(shi)吸(xi)水(shui)(shui)(shui)(shui)(shui)性(xing)特別強(qiang)。上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)(shui)石(shi)(shi)由于暄(xuan)而脆易于造型,可(ke)隨意鑿槽、鉆洞(dong)(dong)、雕刻出各(ge)式各(ge)樣的形狀。上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)(shui)石(shi)(shi)天(tian)然洞(dong)(dong)穴(xue)(xue)很多,有(you)的互相穿連(lian)通(tong)氣,小的洞(dong)(dong)穴(xue)(xue)如(ru)氣孔,這(zhe)就是吸(xi)水(shui)(shui)(shui)(shui)(shui)性(xing)強(qiang)的主要(yao)原因(yin)。在(zai)上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)(shui)石(shi)(shi)上(shang)(shang)(shang)的洞(dong)(dong)穴(xue)(xue)中,填(tian)上(shang)(shang)(shang)泥(ni)土(tu)可(ke)植(zhi)花(hua)草(cao),大的洞(dong)(dong)穴(xue)(xue)可(ke)栽(zai)樹木(mu),由于石(shi)(shi)體吸(xi)水(shui)(shui)(shui)(shui)(shui)性(xing)強(qiang),植(zhi)物生(sheng)長(chang)茂盛,開(kai)花(hua)鮮艷。上(shang)(shang)(shang)水(shui)(shui)(shui)(shui)(shui)石(shi)(shi)可(ke)以散發(fa)濕氣,用它造假山或盆景,都有(you)濕潤環境(jing)的作用。
上水(shui)石又稱吸(xi)水(shui)石,盆(pen)(pen)中蓄水(shui)后,頃刻可(ke)吸(xi)到頂端。石上可(ke)栽植野草、蘚苔(tai),青(qing)翠蒼潤,為(wei)制作(zuo)盆(pen)(pen)景的佳石。 沙積(ji)石,暄(xuan)(xuan)而脆,但吸(xi)水(shui)性很強;石灰(hui)石硬度稍(shao)高,結構比沙積(ji)石細密。上水(shui)石易于造型,由于暄(xuan)(xuan)而脆,可(ke)隨(sui)意鑿槽、鉆洞、雕刻出心中理想的形(xing)象。
