应用311-A拟饱和最优回归设计试验方案，通过田间试验建立烟后稻深两优5814移栽密度、施氮量、施钾量与产量的数学（回归）模型。结果表明，单因素对产量的影响为施氮量＞移栽密度＞施钾量；两因素互作对产量的影响为移栽密度＋施氮量＞移栽密度＋施钾量＞施钾量＋施氮量。经模拟寻优表明，最优组合是移栽密度21.0万丛· hm -2、施钾量（K2 O ）138.1 kg · hm-2、施氮量（N ）143.4 kg · hm -2，拟获得的深两优5814的最高产量为8908.18 kg · hm -2。
應用311-A擬飽和最優迴歸設計試驗方案，通過田間試驗建立煙後稻深兩優5814移栽密度、施氮量、施鉀量與產量的數學（迴歸）模型。結果錶明，單因素對產量的影響為施氮量＞移栽密度＞施鉀量；兩因素互作對產量的影響為移栽密度＋施氮量＞移栽密度＋施鉀量＞施鉀量＋施氮量。經模擬尋優錶明，最優組閤是移栽密度21.0萬叢· hm -2、施鉀量（K2 O ）138.1 kg · hm-2、施氮量（N ）143.4 kg · hm -2，擬穫得的深兩優5814的最高產量為8908.18 kg · hm -2。

Using 311-A optimal fitting saturated regressive design , the regression model for ‘Shenliangyou 5814’ rice rotated after Tobacco was established with the factors in transplanting density , nitrogen rate and potassium rate .The results indicated that the effects of single factor on rice yield revealed in order of nitrogen rate >transplanting density > potassium rate .The interaction effect between two factors were in order as transplanting density and nitrogen rate > transplanting density and potassium rate > nitrogen rate and potassium rate .The optimum combination in factors was simulated with computer optimization ,which was in transplanting density 210 000 hills · hm-2 ,potassium rate (K2O) 138.1 kg · hm -2 and nitrogen rate (N) 143.4 kg · hm -2 for the highest rice yield in 8 908.18 kg · hm-2 .
