摘要 经分析DRIS存在两类理论缺陷:两正态分布的营养元素的比值分布为正偏的非常态;DRIS在营养元素等比不等量变化时存在诊断盲区。依据多维正态分布的二次型理论,以及等概率平衡观点,建立优于DRIS,以及与临界值诊断形式统一的“平衡态诊断施肥综合法”BDRIS。当营养元素相关矩阵R=I(单位矩阵),即不考虑元素颉颃作用时,BDRIS简化为临界值诊断。同时,还提供了SAS语言编写的诊断程序。 Analyses have shown that two kinds of theoretical defects exist in DRIS: the distribution of the ratios of twonormally-distributed nutrition elements is abnormal of positive skewness. There is a blind diagnostic area in DRIS on theoccasion when the nutrition elements change in equal proportion but with unequal amount. In the light of the quadratic formtheory on multi-dimensional normal distribution and the balance of equal probability, this paper constructs BDRIS - 'BalanceDiagnosis and Recommendation Integrated System' , which features unitarity and exceeds DRIS. When the matrix ofnutrition elements R= I (identity matrix), i.e., the effects of elements' reciprocal countering is disregarded, BDRIS will besimplified to the diagnosis of critical value. In addition, this paper also provides a diagnosis program written in SASlanguage.
