| 摘 要： | 采用Ｌ９（３４）正交试验，得出秧龄对三系杂交中籼协优５７产量的影响最大，氮素水平次之，密度和施钾量的影响较小。协优５７在合肥地区作一季中稻种植，以５月１８日播种，秧龄４３ｄ，施纯氮２６２．５ｋｇ／ｈｍ２，密度２２．５万～３５万穴／ｈｍ２ 为宜。

| Abstract: | The straight cross experiment in seeding age,planting density of rice combination Xieyou 57,and N and K fertilizer amount was studied.The results showed that the seedling age had a greater effect on yield than N fertilizer applied and the planting density and K fertilizer had little effect on yield.The cultivation measures of Xieyou 57 used as single middle rice were as follows:seeding on 18,May,43day seedling age, the amount of N fertilizer:262.5kg/hm 2and the planting density:225～350 thousand seedling/hm 2 in Hefei region. |
