多年来的生产实践证明,把有机肥(如饼肥、人粪尿、绿肥、厩肥、堆肥等等)与化肥结合起来施用,如果其他生产措施跟得上,作物就能生长健壮、繁茂,年年“五谷丰登”。这是什么原因呢?有机肥增产的秘密在哪里呢?营养最丰富的“食粮”秘密之一就在于有机肥供结的营养多样而全面。我们知道,植物正常生长发育,需要几十种营养元素。其中有些的需要量很大,叫“大量元素”,属于这类的有氮、磷、钾、钙、碳、氢、氧、镁、硫等。另外,有些营养元素,植物需要的并不多,甚至极少,但它们在植物体内起着特殊的作用,这叫“微量元素”,如硼、锌、铜、锰、钼等等。植物对 Over the years, production practices have proven that organic fertilizers (such as cakes, manure, green manure, manure, compost, etc.) can be combined with chemical fertilizers. If other production measures are followed, the crops will grow robustly and flourish. “Fine harvest.” What is the reason for this? Where is the secret of organic fertilizer production increase? One of the most nutritious “food” secrets lies in the diversity and comprehensiveness of organic fertilizer supply. We know that normal plant growth requires dozens of nutrients. Some of them require a large amount of resources and are called “mass elements.” Nitrogen, phosphorus, potassium, calcium, carbon, hydrogen, oxygen, magnesium, sulfur, and the like belong to this category. In addition, some nutrients, plants do not need much, even very little, but they play a special role in the plant body, which is called “microelements” such as boron, zinc, copper, manganese, molybdenum and so on.
