以未腐解有机物培肥土壤的理论为依据,介绍利用玉米深加工过程中产生的副产品及下脚料,采用挤压造粒法生产有机无机复混肥的工艺技术、主要工艺参数和自控水平。结合笔者多年经验,设计的连续生产工艺由电脑控制,基本实现自动化。同时对该种配方肥经过3年的田间试验,取得较好效果。
Based on the theory of not decomposing organic matter to fertilize the soil, this paper introduces the technology, the main process parameters and the level of self-control of the production of organic-inorganic compound fertilizer by the extrusion granulation method by using the by-products and scraps produced in the deep processing of corn. Combined with the author’s many years of experience, the design of the continuous production process controlled by the computer, the basic automation. At the same time, the formula fertilizer after three years of field trials, and achieved good results.
