1。有机肥料由有机物质组成的肥料,包括绿肥、油饼、禾秆等植物性肥料,粪尿类、鱼肥等动物性肥料,以及这些肥料的混合物如厩肥、堆肥等。特点是含有大量有机质和多种营养元素,来源广,积制方便。一般肥效较缓慢而持久,并能产生腐殖质,改良土壤。同无机肥料合理配合施用,能提高肥效。化学肥料中的尿素、石灰氮等是人工制成的有机物质。 2。无机肥料也称“矿质肥料”或“化学肥料”。由无机物质组成的肥料,如硫酸铵、过磷酸钙、磷矿粉、氯化钾、石灰、草木灰等。绝大多数的化学肥料属这种肥料。化学肥料中的尿素、石灰氮等是人工制成的有机物质,性质接近无机物,不能产生腐殖质,习惯上当作无机肥料。
1. Organic fertilizers Organic fertilizers include plant fertilizers such as green manure, oil cakes and straw, animal fertilizers such as manure and fish manure, and mixtures of these fertilizers such as manure and compost. Characterized by a large number of organic matter and a variety of nutrients, wide source, the plot system convenient. Fertilizer is generally slow and lasting, and can produce humus, soil improvement. Reasonable with inorganic fertilizer application, can improve fertilizer efficiency. Chemical fertilizers in the urea, lime nitrogen is made of artificial organic matter. 2. Inorganic fertilizers are also called “mineral fertilizers” or “chemical fertilizers.” Fertilizers composed of inorganic substances, such as ammonium sulfate, superphosphate, phosphate rock, potassium chloride, lime, ash and so on. The vast majority of chemical fertilizers belong to this fertilizer. Chemical fertilizers urea, lime nitrogen is made of artificial organic matter, the nature of close to inorganic matter, can not produce humus, used to be used as inorganic fertilizers.
