"in leaf"的含義解析
"in leaf" 是英語中的固定搭配,形容樹木或植物處于"長滿葉子"或"枝葉茂盛" 的狀态,強調植物正處于生長周期中葉片完全展開的活躍階段。其反義為"落葉狀态"(bare或leafless)。
植物生長狀态
指樹木、灌木等在春季或生長季葉片完全展開後的繁茂景象。例如:"By April, the oak trees were fully in leaf."(到四月時,橡樹已枝葉繁茂)。
生态與季節标志
該短語常作為物候學指标,标記季節變化。溫帶地區落葉林春季"in leaf"象征新生,如英國皇家植物園邱園記錄中提及:"Beech forests in Europe come in leaf by mid-May, signaling the end of frost risks"(歐洲山毛榉林五月中旬長葉,預示霜凍結束)。
修剪或移植樹木需避開"in leaf"期,以減少水分流失壓力。劍橋大學植物園指南指出:"Transplanting deciduous trees is optimal when out of leaf"(落葉樹移植宜在無葉期進行)。
詩人常以"in leaf"隱喻生命力,如濟慈在《秋頌》中描寫"Trees in leaf whispering hymns of abundance"(枝葉繁茂的樹木低吟豐饒頌歌)。

該短語僅用于植物,與“leaf”的其他含義(如書頁、金屬箔)無直接關聯。若表示“翻書頁”,需用動詞形式 leaf through。
