Q优6号具有产量高、米质好、适应性好等优点。采用五元二次回归正交旋转组合设计,对促进水稻高产的密度、氮、磷、钾肥不同用量和氮肥次数进行了试验研究与分析。结果表明Q优6号稻谷产量以10.5t/hm2以上为目标,优化农艺措施方案:种植密度为1.208 0～1.229 6万株/667m2,施氮肥(纯氮)9.862～10.138kg/667m2,分3次施用(60%作底肥,20%作分蘖肥,20%作穗肥),施磷肥(五氧化二磷)6.052 5～6.367 5kg/667m2,施钾肥(氧化钾)8.972～9.528kg/667m2。
Q No. 6 with high yield, good quality, good adaptability and so on. The five-element quadratic regression orthogonal rotation combination design was used to study and analyze the density, nitrogen, phosphorus and potash fertilizers and the number of nitrogenous fertilizers to promote high yield of rice. The results showed that the yield of Qyou 6 was above 10.5 t / hm2, and the agronomic measures were optimized. The planting density was 1.208 0-1.2965 6 000 / 667m2, nitrogen fertilizer (pure nitrogen) 9.862-10 10.138kg / 667m2, (60% as base fertilizer, 20% as tillering fertilizer, 20% as panicle fertilizer), phosphorus fertilizer (phosphorus pentoxide) 6.052 5 ~ 6.367 5kg / 667m2, and potassium fertilizer (potassium oxide) 8.972 ~ 9.528kg / 667m2.
