复合肥与复混肥是两种不同类型的化学肥料，二者之间的区别主要是： 　　1生产工艺不同。复合肥是通过化学反应合成，其养分含量均一，颗粒大小一致。而复混肥是通过物理混合而成，生产工艺简单，养分不均，效果差。 　　2养分含量不一。复合肥养分一般固定，氮磷钾各为 15％ Compound fertilizer and compound fertilizer are two different types of chemical fertilizers, the main difference between the two is: 1 different production processes. Compound fertilizer is synthesized by chemical reaction, its nutrient content is uniform, the particle size is consistent. The compound fertilizer is made by physical mixing, the production process is simple, nutrient uneven, poor results. 2 different nutrient content. Fertilizer nutrients are generally fixed, nitrogen and phosphorus are 15%
