前言碳铵粒肥深施是近年来发展的一项科学施肥新技术。它具有提高氮素利用率、节省用肥、增加农作物产量等优点。此外,碳铵粒肥还具有挥发少、不结块、便于深施和利于机械施肥等特点。因此,大力推广碳铵粒肥深施,对于降低农本,促进农业增产增收和实现机械化施肥有一定的意义。推广粒肥深施,关键是研制适合于化肥厂配套生产粒肥的造粒机。为了与小化肥厂用的离心机配套使用,造粒机台时产量为4～6吨/时。水稻施肥水平按每亩一次施碳铵
Introduction Ammonium fertilizer is a new scientific fertilization technology developed in recent years. It has the advantage of improving nitrogen utilization, saving fertilizer and increasing crop yield. In addition, ammonium carbon grain fertilizer also has less volatile, non-caking, easy to deep and conducive to mechanical fertilization and so on. Therefore, vigorously promote the application of ammonium bicarbonate fertilizer, for reducing agricultural capital, to promote agricultural production and income to achieve mechanized fertilization is of some significance. To promote the application of granule fertilizer, the key is to develop a pelletizing granulator suitable for the production of granule fertilizer for the fertilizer plant. In order to support the use of small centrifuges with fertilizer plants, granulation machine when the output of 4 to 6 tons / hour. Fertilizer application of ammonium fertilizer per acre once
