小麦单位面积产量是由单位面积穗数、每穗粒数和粒重等三个因素构成,这三个因素随自然条件和品种特性的不同,对产量的影响效应也各不相同.所以在一定的自然条件下,弄清这三个因素对产量以及三者之间的关系,对小麦生产是有意义的. 本文应用多元统计的方法,讨论了小麦单位面积产量构成因素对产量的贡献以及各因素之间的关系,以便为当地小麦生产服务.
The yield per unit area of wheat is composed of three factors: the number of spikes per unit area, the number of grains per spike and grain weight. These three factors have different effects on yield depending on the natural conditions and variety characteristics. Therefore, , It is significant for the wheat production to understand the yield and the relationship among the three factors.This paper applies the method of multivariate statistics to discuss the contribution of the yield components of the yield per unit area of wheat The relationship between factors in order to serve local wheat production.
