| 摘 要： | 2008-2010年，采用二次回归正交旋转组合设计方法进行研究，建立了威宁球茎草芦(Phalaris tuberosa cv.Weining)主要栽培因子（播种量、有机肥、氮肥、磷肥、钾肥和种子产量）关系的数学模型。通过效应分析，得出各试验单因子对种子产量影响的顺序为播种量＞氮肥＞有机肥＞磷肥＞钾肥；试验双因子交互效应以播种量和氮肥、播种量和磷肥、氮肥和钾肥间效果较显著。寻优结果表明，在播种量为3.75 kg·hm-2、有机肥为7 500 kg·hm-2、尿素为450 kg·hm-2、磷肥为750 kg·hm-2和钾肥为450 kg·hm-2的组合条件下，其种子产量达449.50 kg·hm-2，可获最大经济效益。

| Abstract: | A method of quadratic regression orthogonal rotation design was used to establish mathematical models for studying the relationships between seed yield of Phalaris tuberosa cv.Weining and five main cultivation factors(sowing rate,organic,nitrogen,phosphate and potash fertilizer) in 2008-2010.The results indicated that the order of the impact of various factors to the seed yield was the sowing rate>nitrogen fertilizer>organic fertilizer>phosphate fertilizer>potassium fertilizer.The analysis of two-factor interaction effects showed that the interaction effects between the seeding rate and nitrogen fertilizer;the seeding rate and the phosphorus fertilizer;or the nitrogen and the potassium fertilizer were more significant ot the seed yield.The optimum cultivation conditions for seed production of P.tuberosa cv.Weining were: sowing rate 3.75 kg·hm-2,organic fertilizer 7 500 kg·hm-2,nitrogenous fertilizer 450 kg·hm-2,phosphate fertilizer 750 kg·hm-2 and potash fertilizer 450 kg·hm-2.The highest seed yield was obtained at 449.50 kg·hm-2. |
