马蹄莲是一种多年生的草本植物,叶色碧绿,花姿优美。叶尖枯萎是马蹄莲的常见病,表现为叶的尖端发黑、脱落和滴水。叶尖枯萎是马蹄莲缺钾的病状表现。马蹄莲生长需要大量的钾,而盆内土壤中营养元素有限,钾又极易溶解于水,会随过量的水分渗出,造成植物在长期生长过程中钾元素供给量的不足。钾在植物体内起着很多种催化作用,在植物整个代谢过程中处于重要的地位。在植物缺钾时,由于植物体内部 Calla is a perennial herb, leaf color green, graceful flowers. Leaf wilt is a common disease of calla, manifested as the tip of the leaf black, shedding and dripping. Tip wilt is the manifestation of calyx deficiency potassium. Calla growth requires a large amount of potassium, while nutrients in pots are limited. Potassium is extremely soluble in water and exudes with excess water, resulting in a deficit of potassium supply in the long-term growth of plants. Potassium plays a great variety of catalysis in plants and plays an important role in the entire metabolism of plants. In plants potassium, due to plant body inside
