農讀EP.17：鈣肥的漫長旅程-你補的鈣，果實還沒收到，葉片卻先跟你說謝謝！？
from 農.讀 · host 阿德
土壤鈣含量明明正常，為什麼果實還是缺鈣？阿德從鈣靠木質部蒸散流移動的物理機制切入，解釋果實蒸散量低、天生難以獲得足夠鈣素的根本原因，並說明水分管理不穩定如何加劇鈣運輸中斷。同時探討葉面補鈣的作用機制——不見得是鈣直接運送到果實，更可能是提升整體供應量讓果實獲得更多，並比較氯化鈣、硝酸鈣、螯合鈣三種形態的適用時機與優缺點。最後提出三個改善建議從穩定水分管理出發，搭配果實發育初期提早葉面補鈣，以及根據生育期選擇正確鈣肥形態，幫助農友從根本解決缺鈣衍伸的大小毛病與困擾。 有問題，問阿德：[email protected] -- Hosting provided by SoundOn
