摘要：

为探究不同秧龄和栽培密度对春优801生育期和产量的影响，开展秧龄试验和栽培密度试验。秧龄试验采用双因素裂区试验设计，以6月25日（A1）、6月30日（A2）和7月5日（A3）3个播种期为主处理，7月20日（B1）、7月25日（B2）和7月30日（B3）3个移栽期为副处理。栽培密度试验采用单因素随机区组设计，设置4种不同栽培密度，每公顷分别移栽27.8万穴（C1）、23.8万穴（C2）、20.8万穴（C3）和18.5万穴（C4）。结果表明，机插栽培下，秧龄对生育期和产量有显著（p0.05）影响。当播种期相同时，随着秧龄的延长，播种期—齐穗期天数延长，齐穗期—成熟期天数缩短，全生育期延长。3个播种期下，均以秧龄25 d时产量最高。栽培密度对生育期无显著影响，2021年各处理之间产量无显著差异，但2022年C1处理产量最高，且显著高于C4处理。综上，春优801在衢州地区作双季晚稻种植，秧龄25 d，每公顷栽培27.8万穴时，机插易获得高产。

Abstract:

To investigate the effects of different seedling ages and planting densities on the growth period and yield of Chunyou 801，seedling age and planting density tests were conducted. The seedling age test employed a split-plot design with two factors，using three sowing periods，June 25（A1），June 30（A2），and July 5（A3），as the main treatments and three transplanting periods，July 20（B1），July 25（B2），and July 30（B3），as the sub-treatments. The single factor randomized block design was used in planting density test with four cultivation densities：27.8×104 hills per hectare（C1），23.8×104 hills per hectare（C2），20.8×104 hills per hectare（C3）and 18.5×104 hills per hectare（C4）. The results showed that seedling age had a significantly（p0.05）effect on whole growth period and yield under machined-transplanting cultivation. When the sowing period was the same，as the seedling age increased，the days from sowing to heading period prolonged，the days from heading to maturity period shortened，and the whole growth period prolonged. The yield was the highest at 25 d seedling age. The planting density had no significant effect on the growth period. There was no significant difference among treatments in 2021. However，in 2022，the C1 treatment had the highest yield and was significantly higher than the C4 treatment. Overall，Chunyou 801 is suitable for planting as double-cropping late rice in Quzhou. The appropriate seedling age of mechanical transplanting is 25 d，and the planting density is 27.8×104 hills per hectare，which is easy to obtain high yield.
