摘　　要：对豫东平原夏花生生产量构成因素进行了统计分析.结果表明:公顷株数对产量的贡献最大,单株果数次之,百果重居三.因此,在高产栽培中应在保证一定公顷株数的基础上,力争增加单株果数,提高百果重,以提高产量.A statistical analysis of the factors for the yield of summer peanut in Yudong plain is presented in this paper, Among many factors, the number of individual peanut plant per hectare plays the first role. and the number of pods per plant and 100 - pod weight play the second and the third role, In order to improve thc yield of peanut, the sufficient number of individual peanut plant per hectare should be ensured, at the base of the sufficient number of plant per hectare, the number of pods per plant should be increased and 100 - pod weight should be improved.
