通过7个品种,在群体密度相同条件下,研究不同品种边1行至边5行玉米商品品质性状的变化,揭示不同品种、不同边行品质变化的特点及规律性,为生产和科研中协调玉米单株个体与群体的矛盾,为夺取玉米高产、稳产、优质、高效益提供科学依据,更为高产玉米新品种的选育提供借鉴。
Through the seven varieties, under the condition of the same population density, the changes of the quality traits of maize from the first row to the fifth row of different varieties were studied to reveal the characteristics and regularities of the quality changes of different breeds and different sides, and to coordinate the production and scientific research The contradiction between individuals and groups of maize plants provides a scientific basis for seizing the high yield, stable yield, high quality and high benefit of maize, and provides references for the breeding of new maize varieties with higher yield.
