秋大蒜叶尖黄化的补救方法

秋季，种植大蒜易出现叶尖黄化现象，使茎叶不长，茎杆不粗，产量低，品质差，必须加强栽培管理。
　　
　　合理施肥 在秋大蒜生长期间，必须每15～20天根部施一次肥，以优质有机肥为主，每次每平方米蒜地施沤制腐熟的花生饼肥0.5～1千克，兑清水或沤制腐熟的人畜粪水10～15千克后淋施。同时，每10～15天叶面喷施一次800倍蔬菜专用型高美施有机腐殖酸活性液肥水溶液，均匀喷湿所有的叶片，以开始滴水为宜。
　　
　　及时供水 秋季种植大蒜，必须保证有充足的水分供应，土壤要保持湿润，除每天早、晚要各淋一次清水，每次每平方米淋8～10千克外。还要用干枯稻草或其它杂草将畦面覆盖住，草厚3～5厘米，以减少水分损失，保持土壤湿润。
　　
　　防治病虫 秋大蒜受叶斑病、炭疽病、蚜虫、红蜘蛛等为害严重，使叶尖黄化，必须每15～20天叶面喷洒一次1000倍乐斯本、800倍甲基托布津混合液，或25～30倍过磷酸钙与干燥纯净的草木灰混合浸出澄清液，或1500倍安绿宝，600倍敌克松混合液，喷湿叶片滴水为宜，消灭为害叶片的各种病虫。
