摘要
本文综述了提高ＤＲＩＳ诊断准确性的几种改进方法，即计算干物质指数的ＤＲＩＳ（ｍ－ＤＲＩＳ）、调整高产亚群体的样本数、修改养分比的函数方程表达式和修改养分比的表现形式。并简略介绍了以籽粒为诊断对象的ｍ－ＤＲＩＳ养分诊断标准及其应用。
It was reviewed that several modified methods for improved the DRIS diagnostic accuracy in this paper. The modified methods included calculation dry matter index to the DRIS indices(m-DRIS),adjustment high yield subpopulation data bases,modification the forms of nutrient ratio function expression and of nutrient ratio expression and was briefly introduced m-DRIS nutrient diagnosis norms which has examined seed as a diagnostic target and its uasge.
