摘　　要：为了解决浙北地区因早稻收获偏迟 ,连作晚粳稻品种难于应用抛秧栽培的矛盾 ,作者于1995～ 1998年进行了系列栽培试验。结果表明 :连晚采用全生育期 12 0 d左右的特早熟晚粳品种抛秧 ,表现短龄早发 ,茬口适应性广 ,综合措施配套时可以实现高产稳产。在配套技术上关键是掌握适期播种 ,适当减少用种量 ,培育短龄壮秧 ;本田期要确保在一定起点苗数的基础上 ,适当降低前期的用肥量 ,及时搁田 ,增加穗肥用量 ,提高成穗率 ,争取大穗高产。The studies were carried out in 1995~1998 to solve the problems that late season Japonica rice cultivars were difficult to be planted in seedling broadcasting because of late harvest of early season rice in the northern Zhejiang. The results showed that the extraearly maturing late season Japonica rice cultivars with growth duration around 120 days should be chosen, and that sowing at the suitable date and lower rate, raising the healthy seedlings with less leaves, decreasing fertilization rate properly at the early stages and increasing fertilization rate at the panicle stage and draining the paddy fields in time were the key parameters for achieving the high and stable yield by these cultivars.
