为了考察籼粳杂交稻春优84在浙东地区作连作晚稻栽培的可行性，以春优84单季栽培和晚粳稻宁84单双季栽培为对照，笔者在宁波市镇海区开展了春优84分期播种、不同秧龄移栽试验。结果表明，春优84在浙东地区作连作晚稻种植，宜在6月30日之前播种，产量可达到500 kg/667 m2。

In order to study the adaptability of indica/japonica hybrid rice Chunyou84 planting as continuous cropping late rice in the region of Eastern Zhejiang, a experiment was conducted at Zhenhai district to ascertain the yield changing with different sowing period and seedling age. The yield of Chunyou 84 could achieve 500 kg/667 m2 when planting as continuous cropping late rice and sowing before 30 June.
