银川平原是我国春小麦高产地区之一。已出现了亩产超千斤的田块。目前,为了满足生产发展的需要,急需选育出比现有品种高产稳产的新品种。本试验的目的在于,通过对银川平原推广面积较大的几个高产品种产量及构成因素的分析,以探明本地区小麦高产品种的生产潜力,从而为选育适应本地区种植的高产稳产新品种 Yinchuan Plain is one of the spring wheat high-yield areas in China. There have been plots of super-kilograms per mu. At present, in order to meet the needs of the development of production, it is urgently necessary to breed new varieties that are more stable and stable than the existing varieties. The purpose of this experiment is to analyze the yield and components of several high-yielding varieties in Yinchuan Plain, so as to find out the production potential of high-yielding wheat varieties in this area, Variety
