为降低复混肥料生产成本 ,提高其使用效果 ,采用玉米作物简单经典的肥料效应函数法 ,讨论已知主要原料价格及养分含量 ,举例说明如何计算最佳推荐施肥量 (纯收入最大 )和复混肥料原料优化配方 (成本最低 )。并指出复混肥料厂提高质量、降低成本应重视应用科学技术
In order to reduce the compound fertilizer production cost and improve its using effect, the simple and classic fertilizer effect function method of corn crops is used to discuss the price and nutrient content of the known main raw materials. Examples are given to illustrate how to calculate the best recommended fertilizer amount (maximum net income) and complex Mixed fertilizer raw material optimization formula (the lowest cost). And pointed out that compound fertilizer plant to improve the quality and reduce costs should pay attention to the application of science and technology
