边际效应对玉米子粒商品品质的影响

The Influence of Marginal Effects on the Commercial Quality of Maize Grain

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。

Changes of commercial quality of maize at first row to fifth row of land margin were studied in experi- ment of 7 varieties and same population density. Characters and regularity of this change of different varieties were discovered. This study supplied scientific basis for solving contradiction of individual and group and achieving high and stable yield, high quality and high benefit. This provided reference for breedinz of new maize varieties.
