多种化学肥料经混合后,一次施肥可以同时满足作物对N、P、K等营养元素的需求,起到一肥多用,诸素并增,互相促进,协调补充的作用,是农业生产上经济用肥的一个好方法。配制混合肥料,主要抓下面三个环节: 一、确定配肥的组分配制混合肥料,必须考虑到肥料混合后的相互影响。如混合不当,将会引起肥料的肥效损失、肥效降低或施用性状变坏。各种肥料能否混合,大体可分以下三种情况:①可以混合:肥料经混合后,不但养分没有损失,而且可以取长补短,利于作物吸收利用。如碳酸氢铵和过磷酸钙混合,即可防止氨的挥发,又可中和过磷酸钙中的游
A variety of chemical fertilizers after mixing, a fertilization can simultaneously meet the crop of N, P, K and other nutrients demand, play a fat and more use of all the other and promote each other to promote and coordinate the role of complementarity is agricultural production economy A good way to use fat. Preparation of compost, mainly to grasp the following three links: First, determine the composition of fertilizer Manure compost, fertilizer must be taken into account the interaction after mixing. Such as improper mixing, fertilizer will result in the loss of fertilizer efficiency, fertilizer use or deterioration of the traits. Whether a variety of fertilizers can be mixed, the general can be divided into the following three conditions: ① can be mixed: fertilizer by mixing, not only no loss of nutrients, but also learn from each other, which will help absorb the use of crops. Such as ammonium bicarbonate and superphosphate mixed, you can prevent ammonia volatilization, but also in the superphosphate in the tour
