|---|---|
| CO₂ | 无需添加 (添加 CO₂ 可促进繁茂生长) |
| 水温 | 20°C – 28°C |
| pH | 5.0 – 8.0 |
| 造景位置 | 绑缚于沉木或青龙石/岩石上 (切勿将根茎埋入底床) |
| 生长速度 | Slow |
| 养护难度 | 极易 |
| 科属 | Polypodiaceae |
如何修剪与繁殖铁皇冠 (微囊蕨)？
Snip old, damaged or algae-covered fronds close to the rhizome; growth is slow, so a big trim is rarely needed (about once a year in many tanks). Propagate by cutting the rhizome into sections with several fronds each, or detaching the plantlets that form on leaf tips, margins and undersides once they have roots and a few leaves.
铁皇冠 (微囊蕨)有哪些常见问题？
Regular brown/black dots or streaks in rows under mature fronds are spore cases (sporangia) — normal, not a disease. Genuine spreading dark patches and dying fronds point to a nutrient shortage (commonly blamed on low potassium); a soft, declining rhizome means it was buried; algae settles on the slow fronds under too much light.
如何解决铁皇冠 (微囊蕨)的常见问题？
Leave the spore dots alone; remove damaged fronds and dose a complete fertiliser; lift any buried rhizome onto wood or stone; lower the light, add faster-growing plants and algae grazers.
