[目的]研究播期、密度、施肥量和水分对早稻生长发育与产量的影响,筛选最佳栽培因子组合。[方法]对杂交早稻金优402进行播期、密度、施肥量和水分4因素3水平的正交试验。[结果]播期和施肥量是影响早稻生育期和产量的主要因素;播期对金优402的生育期和产量影响极显著,施肥量对早稻生育期和产量的影响显著。早稻高产栽培的最佳组合为:播期3月22日,密度135万/hm2,施肥总量225 kg/hm2,水分刚淹没土表。[结论]为农业生产提供参考。
[Objective] The research aimed to study the effects of sowing date, planting density, fertilizer amount and water on the growth and yield of early rice and screening the best combination of cultivation factors. [Method] The orthogonal experiment of sowing date, density, fertilizer amount and water 4 factor 3 level of early hybrid rice Jinyou 402 was conducted. [Result] Sowing date and fertilizer amount were the main factors affecting the growth and yield of early rice. Sowing date had a significant effect on the growth and yield of Jinyou 402. The effect of fertilization on growth period and yield of early rice was significant. The best combination of early rice high-yielding cultivation is: sowing March 22, the density of 1.35 million / hm2, total fertilization 225 kg / hm2, water just submerged soil table. [Conclusion] It provides a reference for agricultural production.
