锰是植物正常生活和生长所必需的微量营养元素之一。它的作用不能用别的营养元素来代替。如果土壤中植物能吸收的锰太少,植物就会出现缺锰症状,农作物的产量和质量都要下降。适当的施用锰肥能够消除缺锰症状,提高农作物的产量和质量。锰肥的用量少,成本低,是充分发挥农业生产潜力,增产增收的有效措施之一。 Manganese is one of the micronutrients necessary for the normal life and growth of plants.

If too little manganese is absorbed by plants in the soil, the plants will suffer from the symptoms of manganese deficiency and the yield and quality of the crops will have to be reduced. Proper application of manganese fertilizer can eliminate manganese deficiency symptoms and improve the yield and quality of crops. Manganese fertilizer with less dosage, low cost, is to give full play to the potential of agricultural production, increase production and income of effective measures.
