运用最优设计，对杂交香稻泸优明占进行插植密度、施K量、施N量3项栽培措施的研究。通过建立产量和稻米品质与3项栽培措施的回归模型，分析3项栽培措施对产量和稻米品质的影响，结果表明，这3项措施对产量和稻米品质都有不同程度影响。并经计算机模拟筛选出高产、低垩白粒率的优化措施：平均21．45万丛/hm2，施K2 O 140．2 kg/hm2，施纯N 136．6 kg/hm2。
運用最優設計，對雜交香稻瀘優明佔進行插植密度、施K量、施N量3項栽培措施的研究。通過建立產量和稻米品質與3項栽培措施的迴歸模型，分析3項栽培措施對產量和稻米品質的影響，結果錶明，這3項措施對產量和稻米品質都有不同程度影響。併經計算機模擬篩選齣高產、低堊白粒率的優化措施：平均21．45萬叢/hm2，施K2 O 140．2 kg/hm2，施純N 136．6 kg/hm2。

Effects of transplanting density ,nitrogen ( N) application dosage and potassium ( K) applica-tion dosage on hybrid rice“Luyoumingzhan”were studied by optimal design .Regression models between yield , quality and the three cultivation measures were built to study the effects of the three cultivation measures on rice yield and quality.The results showed that ,the yield and quality were influenced in various degrees .An opti-mization measure for high yield and low chalky ratio was simulated by computer ,which was 214500 clumps per ha,140.2㎏N per ha and N 136.6 kg per ha.
