農讀EP.20：農作物的鋅事，有沒有鋅真的很重要！從花芽分化到果實發育，沒鋅不可！
from 農.讀 · host 阿德
摘要：花開了卻坐不了果？新葉縮小節間短縮、果實畸形偏小？這些看似不同的問題，根源可能都是同一個微量元素的缺乏：鋅。今天阿德介紹鋅在植物體內的兩大核心功能：透過生長素合成影響細胞伸長，以及影響花粉活力、花粉管伸長與果實細胞分裂。另外分享台灣農地最常見的缺鋅成因：磷肥長期累積造成的磷鋅拮抗，以及偏鹼性土壤與有機質不足的問題。阿德提供三層解方：暫停磷肥施用、花期前兩週預防性葉面噴施硫酸鋅、長期增加土壤有機質，幫助果菜類與果樹農友從根本改善坐果率與果實品質，最後強調補鋅的關鍵在於時間點，預防優先於補救。 有問題找阿德：[email protected] -- Hosting provided by SoundOn
