　　为了确定南方砂梨二次花分级标准，2010—2012年连续对2个具有代表性的丰水梨果园进行了调查统计、分类研究，在原二次花分级标准I的基础上，拟定了砂梨二次花发生的新分级标准II。研究了二次花2个分级标准的病情指数间的关系以及开花率与二次花指数问的相互关系。结果表明：2种分级方法在二次花较重时（二次花指数＞45）时，对二次花指数调查结果影响不显著，而在二次花较轻（二次花指数＜45）时，则对二次花指数的调查结果有显著的影响。分级标准I方法的二次花指数调查值显著偏高，而分级标准II调查值显著偏低。归纳出分级标准II为评价二次花发生相对准确、实用的模式。

In order to determine the classification criterion of reflorescence, a comprehensive survey of reflorescence of Hosui cultivar were accomplished in 2010-2012. The results formed a new classification criterion II with a great improvement upon the old classification criterion I. The author studied the relationship between classification criterion I and classification criterion II, and the relationship between the rate of reflorescence and classification criterion. The analysis of coefficients showed that: no significant differences were observed in the rate of reflorescence (rate of reflorescence>45) between the two classification criterion and significant differences were observed in the rate of reflorescence (rate of reflorescence<45). The rate of reflorescence of classification criterion I was higher, while the rate of reflorescence of classification criterion II was lower. The author also summarized the accurate and practical structure model with classification criterion II.
