摘　　要：农作物生长中,对其品质影响因素较多,我们主要关注的因素为土壤及其地球化学环境对大米品质的影响。从分析大米营养成分出发,推导出影响大米品质的一组特征元素,从而将农业问题转化为地球化学问题。从分析土壤中特征元素的分布特征,推断出大米品质的产区分布,为农业规划及不同深加工目的服务,达到地球化学为农业服务的目的。Many factors affect the quality of crops during their growing, and the chief factor the authors are concerned about is the soil and its influence on the rice quality. Based on an analysis of the nutrition composition of rice, the authors infer that there exist a set of characteristic elements that affect the rice quality, thus converting the agriculture problem to a geochemical problem. At the same time, according to the distribution features of the characteristic elements in soil, the authors deduce the distribution of rice quality, which can serve agricultural planning and further processing.
