小麦产量的不同构成因素,是在小麦一生中的不同阶段奠定的。但在小麦生育期中,常常受到各种外界因素的影响,从而必然反映在小麦产量的不同构成因素上,进而影响其产量。本文根据因子分析方法,对宁夏银川灌区1986、1987年春小麦产量构成因素之间的关系及其对产量的影响进行探讨。因子分析方法,属多元分析方法的一种,具有主组元分析和聚类分析方法的优点,已被应用于地质、土壤等科学技术的各个广泛领域。
The different components of wheat yield are laid at different stages of wheat’s life. However, in the wheat growth period, it is often affected by various external factors and thus inevitably reflects on the different components of wheat yield, thereby affecting its yield. Based on the method of factor analysis, this paper discussed the relationship between the yield components of spring wheat in Yinchuan Irrigation Area in 1986 and 1987 in Ningxia and its impact on yield. Factor analysis method, which is a kind of multivariate analysis method, has the advantages of principal component analysis and clustering analysis methods and has been applied to a wide range of fields such as geology and soil science and technology.
