摘　　要：以杂交辣椒甘科5号为材料,在张掖市研究了不同肥料处理对制种辣椒种子产量和质量的影响。结果表明,基施N 142.5 kg/hm2、P2O5328.5 kg/hm2、K2O 76.5 kg/hm2,分别于对椒坐果后及辣椒杂交授粉结束后追施N 135.0 kg/hm2、P2O5135.0 kg/hm2、K2O 135.0 kg/hm2时,辣椒种子的千粒重、发芽势、发芽率表现良好;产量最高,为181.25 kg/hm2,较不施肥处理增产81.93 kg/hm2,增产率82.5%。Pepper Ganke 5 is used as test material,the effects of different fertilizer treatments on hybrid seed yield andquality are studied. The result shows that the base application N 142.5 kg/hm2,P2O5328.5 kg/hm2 and K2O 76.5 kg/hm2,dressingthe second level fruit setting and the end of hybrid pollination N 135.0 kg/hm2、P2O5 135.0 kg/hm2 and K2O 135.0 kg/hm2,respectively made the 1 000-grain weight,germination energy and germination percentage increased. The yield is the highest,whichis 181.25 kg/hm2,increased by 81.93 kg/hm2,the yield increase rate being 82.5% higher than of the check no control.
