复(混)合肥料是近年来世界化肥推广施用的一项新技术,也是化肥生产销售高度商品化的产物。在国外,化肥包装、运输、贮存和施用上所花费的投资,相当于化肥成本的50%左右。为了减少这些投资,许多国家都积极生产高浓度的复(混)合肥,七十年代比五十年代提高一倍左右,所生产的聚磷酸铵复合肥养分总量高达70～80%。西欧各国复(混)合肥数量,已占化肥总量的60～70%。现仍在继续发展。
Complex (mixed) Hefei expected in recent years the world fertilizer to promote the use of a new technology, but also a highly commercialized fertilizer production and marketing products. In foreign countries, the investment in the packaging, transportation, storage and application of chemical fertilizers is equivalent to about 50% of the cost of chemical fertilizers. In order to reduce these investments, many countries are actively producing high-concentration Hefei fertilizer, doubling the seventies’s compared with the 1950’s and producing as much as 70-80% of the total ammonium polyphosphate fertilizer compound. Western European countries complex (mixed) Hefei, the total amount of fertilizer accounted for 60 to 70%. Now continue to develop.
