摘　　要：施肥模型是精准施肥的核心。根据当前橡胶树施肥方法现状和橡胶树精准施肥的业务流程,通过对橡胶树精准施肥的实体关系分析,笔者以胶园土壤和叶片养分含量为基准,在橡胶树叶片营养诊断指导施肥方法的基础上,构建中国橡胶树精准施肥基本模型,实现橡胶树精准施肥宏观调控与微观指导的统一。同时,在基本模型的基础上,笔者增加了成本收益分析模块来拓展精准施肥模型。这样不仅能为橡胶树精准施肥提供更加科学合理的决策依据,而且可使精准施肥成本得到进一步优化,从而推动橡胶树精准施肥技术的发展。Fertilization model is the core of precise fertilization. In case of current actuality of rubber fertilization methods and business flow chart of rubber tree precise fertilization, with nutriment contents of rubber plantation soil and leaf, this paper established rubber tree precise fertilization model to realize macro-control and micro-guide unification of rubber tree precise fertilization, which based on nutrients diagnosis of its leaves to conduct fertilizing. But this paper added avails analysis cost model to the base model to open up an exhibition. It not only can prefer more technical and reasonable treasures to rubber fertilizing by the analyze result, And it also can optimize the cost of further precise fertilizing to promote the development of rubber tree precise fertilization.
