不同类型果林间套播花生性状的相关分析和因子分析

Correlation Analysis and Factor Analysis of Traits of Peanut Interplanted with Different Fruit Trees

通过花生品种花育31号在新疆和田地区农科所4种果林间的套播栽培试验,对调查的6个性状的数据利用DPS软件进行相关分析和因子分析,探讨在不同果林中套播花生性状间的相互关系及其差异,并对性状因子结构和因子中主要载荷性状间的关系进行分析,评价在不同果林间花生套播种植的效果。结果表明,在4种果林中套播种植花生时,以在3年生红枣林中产量最高,效益最好;在7年生红枣林中产量位列第二;对6个性状的相关分析和因子分析结果表明,在相应的4个类型的果林中套播种植花生时,不同果林中的花生性状之间的相关关系、性状的因子结构和因子内主要载荷性状间的关系均发生了较大变化。

Correlation analysis and factor analysis of 6 traits of peanut were conducted to investi-gate the relationship and the difference of the relationship in the traits by using the datum gotten from test which the peanut Huayu31 variety was interplanted with 4 different types of fruit trees.Factor structures of traits and relationship of the main loading traits in different factors was also studied in this paper.Meanwhile, effect of peanut interplanted with 4 different types of fruit trees was evalua-ted.The results of the experiment showed that the yield of peanut interplanted with 3 years date tree was the highest and the yield with 7 years date trees was the second.The results of correlation analy-sis and factor analysis of 6 traits indicated that the relationship and the factor structures of traits were changed when peanut interplanted with different fruit trees.The relationship of the main loading traits in different factors changed too accordingly.
