農讀EP.21：花兒不實？沒硼友會讓你的果樹白開花！從結構到開花，從授粉到結果，絕對不可少的硼元素
from 農.讀 · host 阿德
花開滿樹卻坐不了果加上果實龜裂木栓化？這些讓農民心痛的問題，根源可能都指向同一個微量元素：硼。今天阿德解說硼在植物體內的三大核心功能：作為細胞壁果膠交聯的黏合劑、參與糖分韌皮部裝載運輸、以及影響花粉形成品質與花粉管伸長。特別說明硼是所有必需元素中安全使用範圍最窄的，缺硼和硼中毒的臨界點極近，葉面施用濃度必須嚴格控制在千分之零點五(2000倍)左右。並提供三層解方：花期前兩週預防性葉面噴施、低濃度多次施用原則、以及偏鹼性土壤的pH調整策略，幫助果菜類與果樹農友從花期前就做好硼素管理，讓花能成果，開得值得。 有問題找阿德：[email protected] -- Hosting provided by SoundOn
