農讀EP.13：氮肥是把雙面刃：天氣一變熱菜就爛？其實是冬天施肥埋下的伏筆
from 農.讀 · host 阿德
每年開春之後，最怕的就是菜突然大量腐爛，許多人以為是春雨或濕氣的問題，但真正的原因往往出在冬季的氮肥施用過量。阿德從科普角度解析氮肥過量的連鎖反應：冬季低溫導致氮素積累土中，春季溫度回升後微生物爆發、植物快速吸氮，造成細胞壁薄弱、碳氮比失衡，加上春季高濕環境，病原菌趁機入侵。節目提供三層解方，從基礎的施肥時間點與劑量調整、搭配鉀鈣補充，到進階的緩釋肥料與少量多次施肥策略，以及長期改善土壤有機質的根本方案，幫助農友避開春季爛菜危機。 -- Hosting provided by SoundOn
