細葉紅羽毛

細葉紅羽毛的基本資料

栽培難度

適合中級者

壽命

多年生草本。通過修剪可長期維持

體型

高度20-50公分、寬度12-20公分

適宜溫度

22〜28℃

澆水

CO2補充與硝酸鹽、磷酸鹽、鐵質營養補充

光量·照明

需要中等至強光。光越強，紅褐色越濃郁。

CO2·肥料

建議補充CO2（約25-30mg/L）。降低硝酸鹽、增加磷酸鹽和微量元素則顏色會變濃郁。缺乏鐵質時葉子會褪色。

水溫·水質

適溫為22-28℃。喜歡弱酸性軟水（pH5-7.5），但能在一定程度上適應不同水質。

底床·著床

由於生長較大，應植於容量76升以上水族箱的中景至後景。

修剪·繁殖方法

當生長至水面時，修剪頂端後重新種植。也可分割側枝進行繁殖。

注意事項

體型較大，不適合小型水族箱。水草不要丟棄於野外，也不要讓其逃逸出水族箱外。

關於細葉紅羽毛

Ammannia gracilis is a stem plant that turns reddish-brown under strong light. This large 20-50cm perennial suits the mid- to background of aquascapes and can be maintained long-term through trimming and replanting.

開始照料細葉紅羽毛前需要了解的7件事

1. 1Give It Strong Light

   Bright lighting is essential for bringing out Ammannia gracilis's signature cognac-red color. Under weak light it tends to stay green and grow leggy, so place it where light reaches well.

2. 2Plant Mid to Background

   This is a large plant, growing 20-50cm tall and 12-20cm wide, so it looks best planted in groups toward the middle or back of the tank rather than up front. Tanks of 76 liters or more give it room to show its full form.

3. 3Use Nutrient-Rich Substrate

   Because it grows so large, this plant has fairly high nutrient demands from its roots. A nutrient-rich substrate combined with root tabs helps keep leaf color and stem thickness consistent.

4. 4Trim and Replant Cuttings

   As a perennial, overgrown stems can be cut and replanted to keep the plant going indefinitely. Regular trimming both shapes the plant and rejuvenates it.

5. 5Choose Compact Nodes

   Look for a plant with tightly spaced leaf nodes and a sturdy stem, which establishes more easily. Leggy, stretched-out specimens can take longer to regain their proper form once settled in.

6. 6CO2 Boosts Coloration

   This is considered an intermediate-level plant, and growth and coloration tend to be more stable with CO2 injection. It can survive without CO2, but the reddish coloring is harder to achieve and the plant is more prone to legginess.

7. 7Keep Temperature Stable

   Sudden swings in water temperature can damage or drop leaves. Use a heater or chiller as needed through seasonal changes to keep conditions steady and avoid stressing the plant.

細葉紅羽毛的常見問題

Q.Is this plant suitable for beginners?

A.Ammannia gracilis is considered an intermediate-level plant. It needs a bit more attention to lighting and CO2 than easier species, so it's a good next step once you're comfortable with basic stem plants.

Q.Why does it stay green instead of turning red?

A.The main cause is insufficient light. Providing strong lighting for a sufficient duration each day helps bring out the cognac-red coloration.

Q.What tank size does it need?

A.Since it can grow 20-50cm tall and 12-20cm wide, it's best suited to the mid- to background of tanks 76 liters or larger. Smaller tanks can feel cramped for a plant this size.

Q.What should I do if it grows too tall?

A.Cut the top of the overgrown stem and replant it in the substrate as a cutting. Since it's a perennial, repeating this process lets you maintain it indefinitely.

Q.Is CO2 injection required?

A.It's not strictly required, but growth and coloration tend to be more stable with CO2. Without it, the plant is more prone to legginess and weaker red coloration.
