農讀EP.14：磷肥的隱形危機：一冷葉子就變紅？果樹抽梢不開花？我施的磷肥去哪裡了？
from 農.讀 · host 阿德
冬天蔬菜葉片轉紅、果樹開春只抽梢不開花，這兩個農民最常遇到的困惑，背後都指向同一個問題——磷肥在冬季的吸收效率大幅下降。這集阿德從低溫抑制根系活性與磷擴散速度切入，解析磷在花芽分化與醣類轉運中的關鍵角色，同時揭露磷肥施用最常卡住的兩個錯誤方式：表面撒施讓磷到不了根系，以及土壤酸鹼值不對讓磷被固定鎖死。提供三層解方，從調整施肥位置、土壤pH檢測與石灰調整，到冬季葉面噴施磷酸二氫鉀的緊急補救策略，幫助農友大幅提升磷肥利用效率，從根本提高冬季磷肥利用問題。 -- Hosting provided by SoundOn
