荔枝樹晚發新梢處理對增進結果之效果 第一報

The Effect of Delayed Shoot Treatment on Fruit Bearing of Litchi Tree (Ⅰ)

摘要


荔枝在11月-12月發生之晚梢,來年春天拉生花梢結果者甚少,本試驗試行各處理以促生花穗,經於61年-64年(1972-1975)在臺中南投等地,以黑葉高雄早生等品種連續試行三年,結果證明將晚生新梢剪除,其抽穗率可達60-100%,而果實品質亦較佳,不剪者只爲0-30%,當因剪枝可節省養分虛耗抑制發育,故有利於花芽之生成。試驗中亦發現以480ppm之ethrel浸漬新梢,亦有增進抽穗之效,證明ehrel具有抑制發育促進休眠之功用。
