肥料之间以及肥料与农药混合使用,不仅可减少操作程序,节省劳力;而且可提高肥效和药效,降低农业成本.但不是所有的肥料都能与农药混合,也不是肥料与农药混合使用效果都好.一、肥料的相互混合各种肥料间是否可以混合,一般分四种情况:①可以混合.混合后不但养分不能损失,而且还能改善物理性状和提高肥效.②可以暂时混合但不能久放.混合后立即施用没有不良影响,但久放会引起有效养分减少,肥料的物理性状变坏.③可按一定比例混合.如氨水及碳酸氢铵与过磷酸钙混合时,混合氨水及碳酸氢铵的数量应按过磷酸钙的游离酸量来确定.④不能混合.
The combination of fertilizers and fertilizers with pesticides not only reduces operating procedures and saves labor, but also increases fertilizer efficiency and efficacy and reduces agricultural costs, but not all fertilizers can be mixed with pesticides or mixed with pesticides Are good. First, the mutual mixing of fertilizers A variety of fertilizers can be mixed, generally divided into four situations: ① can be mixed after mixing not only nutrients can not be lost, but also to improve physical properties and improve fertilizer efficiency. ② can be temporarily mixed but not For a long time. Mix immediately after application without adverse effects, but long time will lead to effective nutrients to reduce the deterioration of the physical properties of fertilizers. ③ can be mixed in certain proportions. Such as ammonia and ammonium bicarbonate and superphosphate mixed with ammonia and The amount of ammonium bicarbonate should be determined by the amount of free acid superphosphate ④ Not mixed.
