小麦植株细矮,叶片稀少,淡绿色渐变黄,干枯,分蘖少,穗子短小是缺氮的症状。叶片紫绿色,老叶枯死,分蘖少,抽穗成熟迟。种子发芽不旺是缺磷的症状。缺钾时,全部叶片呈蓝绿色,老叶尖和边缘焦黄,甚至变棕色枯死,茎秆弱小,易倒伏。

Small and thin wheat plants, sparse leaves, pale green gradient yellow, dry, less tiller, short ears are symptoms of nitrogen deficiency. Leaves purple green, old leaves dead, less tillering, heading mature later. Poor seed germination phosphorus deficiency symptoms. When potassium deficiency, all the leaves were blue-green, the old tip and edge of the yellow, brown and even brown dead, stalk weak, prone to lodging.
