| 摘 要： | 通过田间试验，豫南粳稻晚播营养生长期缩短14d，灌浆成熟期延长8．5d，单产提高8．43％,品质有所改善。扬花灌浆期间温度降低，有利于提高粳稻的结实率和千粒重，是晚播增产的原因。

| Abstract: | On basis of the field's late sowing experiment of Keng in the South of Henan,it was found that the growth period shorted 14 days,the filling and maturing period prolonged 8.5 days,the single yield increased by 8.43%,and the quality has been improved.Falling the temperature of the flowering and filling period of Keng will facilitate increasing the rate of seeding and the weight of Kilograin,this is the reason why late sowing can increase production. |
