肥料是花生生产的主要投入成本和调控因子，科学施肥对于保证花生生长发育良好和高产优质十分重要。以彩色花生品种彩51为材料，探讨一次性基肥与追肥施用量对花生生长发育、农艺性状及产量的影响。结果表明：与不施肥比较，基肥与追肥均有利于彩51增产；产量最高的施肥方式为基施复合肥600 kg／hm2，不施追肥。过多施用化肥（750 kg／hm2）在一定程度上抑制营养与生殖生长，影响了荚果产量。%Fertilizer is the main cost and cultivation regulation factors of peanut production. The scientific manuring sys-tem is very important to guarantee good growth and high yield and quality. A three repetitions experiment was conducted to explor the respond of one-time fertilization and topdressing with 25% (N1 0-P6 -K9 )common compound fertilizer to peanut cultivar Cai-51. The results indicated that fertilizer supplication was advantageous to pod yield. The suitable kind of fertilizer was 600 kg/hm2 of base fertilizer,and it increased 1 9.7% of the pod yield than that of no fertilizer. The ex-cessive application of chemical fertilizers (750 kg/hm2 )inhibited peanuts’vegetative and reproductive growth in a certain extent,and then affected the pod yield.
