根据作物对各种元素肥料施用的多少,对肥料作了大量、中量和微量元素肥料分类。配方肥料的配制生产,既含有大量元素肥料,也含有作物需要而土壤中没有或者不足的微量元素肥料,各种元素肥料配合施用,相互促进供给作物吸收,用量适当,养分全面,利用率高是配方肥料使作物增产的机理。随着农村劳动力的转移,从事农业生产的人力减少,配方施肥技术的推广普及和配方肥料的生产应用,将使配方施肥料在生产上的推广应用范围逐渐扩大,可以通过各种方式进行配方肥料的投资生产,如果将配方肥料和控释肥料生产技术有机结合,就会对农业的增产增收做出更大的贡献。
According to the amount of fertilizer on the various elements of the crop, the fertilizer made a lot of, the amount of trace elements and fertilizer classification. Formulated fertilizer production, both containing a large number of elemental fertilizers, but also contains crops and the soil is not enough or lack of trace element fertilizers, a variety of elemental fertilizers with the application of each other to promote the supply of crop absorption, the appropriate amount of nutrients comprehensive, high utilization rate The mechanism by which fertilizers increase crops. With the transfer of rural labor, less manpower to engage in agricultural production, the popularization of formula fertilization technology and the production and application of formula fertilizers, the range of popularization and application of formula fertilizers will be gradually expanded, and formula fertilizers can be formulated in various ways Of the investment in production, if the formula fertilizer and controlled release fertilizer production technology organically, it will increase the agricultural production to make greater contribution.
