对杂交晚稻盛泰优9712进行不同播期、移栽期、移栽密度和施氮量进行4因素3水平的正交试验,筛选其最佳栽培因子组合。结果表明:播期、移栽期和施氮量是影响晚稻生育期、产量和米质的主要因素。播期对生育期的影响最大,播期、移栽期和施氮量对产量的影响较大;播期和移栽期对米质的影响较大。盛泰优9712高产优质栽培最佳方案为:6月30日播种,7月15日移栽,移栽密度20.0 cm×20.0 cm,施氮量157.5 kg/hm2。
The orthogonal experiment was conducted on the hybrid late rice Shengtayou 9712 under different sowing date, transplanting date, transplanting density and nitrogen application rate. The best combination of cultivation factors was screened. The results showed that sowing date, transplanting date and nitrogen application rate were the main factors affecting late rice growth period, grain yield and grain quality. Sowing date has the greatest impact on the growth period, sowing date, transplanting date and nitrogen application rate have a greater impact on the yield; sowing date and transplanting period have a greater impact on the quality of rice. The best plan of Shengyouyou 9712 high yield and quality cultivation was sowing on June 30th and transplanting on July 15th, the transplanting density was 20.0 cm × 20.0 cm and the nitrogen application rate was 157.5 kg / hm2.
