一、炉渣微肥简介农作物在生长过程中,不仅需要大量的氮磷钾肥料,而且需要一定数量的铁、锰、硅、钙、铜、钼、硼、锌等元素,人们称之为微量元素肥料。例如:每公顷(垧)土地的麦子,需用锰量100—200克,水稻对锰的需要量还要高10倍。铁、锰量不足,会引起水稻的黄化病和其它病症,严重的可使植株死亡。长期作为水田的土地容易出现缺锰症状。铁合金炉渣中含有农作物生长所需要的 First, the introduction of slag fertilizer Crops in the growth process, not only requires a lot of nitrogen, phosphorus and potassium fertilizer, and requires a certain amount of iron, manganese, silicon, calcium, copper, molybdenum, boron, zinc and other elements, people call it trace elements fertilizer. For example, wheat per hectare (垧) of land requires 100-200 grams of manganese, and rice requires 10 times more manganese. Inadequate amounts of iron and manganese can cause yellowing and other diseases in rice and can cause serious plant death. Long-term land as paddy fields prone to manganese deficiency symptoms.
