摘要
本文介绍了修改的综合诊断施肥法(M-DRIS)对作物养分丰缺的判定方法。并以柑桔为例,列出了M-DRIS指数的计算公式和步骤。应用此法指导农作物施肥,比原法能进一步提高诊断的正确性。
In this paper, a method of judgement of the M-DRIS ( Modified Diagnosis and Recommendation Integrated System) to the plenty and lack of crops nutrient has been introduced. Taking oranges, it lists the calculating formulation of M-DRIS and its steps. Applying this method to guide fertilising the crops can be more accurate to diagnosis.
