Arrowhead field 茨菇田
Stop 9 of the Wetland walk · 濕地路線第9站
Chinese arrowhead, an old wet-field crop, grown here again.
Its tubers are a Chinese New Year food.
Its tall, upright leaves suit dragonflies and damselflies: they perch on the stems, lay eggs on them, and the nymphs climb up them out of the water to become adults.
Growing crops besides rice keeps the farmland varied, for wildlife and for the farmers.
But the invasive apple snails eat arrowhead very fast.
茨菇是傳統水田作物，今日在此重新種植。
茨菇是新年應節食物。
茨菇高而直立的葉柄最適合蜻蜓及豆娘：牠們停在莖上、在莖上產卵，水蠆亦沿莖爬出水面羽化。
種植稻米以外的作物，令農地更多樣，對野生生物及農夫都有好處。
可惜入侵的福壽螺吃茨菇吃得很快。
