| 摘 要： | 为进一步探索"安粳698"的优化高产配套栽培技术,采用二次回归通用旋转组合设计,研究"安粳698"产量与栽插密度、N、P、K施用量间的关系,建立各因素与产量指标的数学模型:Y=548.21-12.83X1-20.21X2+4.29X3+8.75X4+3.80X12-13.64X22-6.32X32-0.20X42-0.56X1X2+3.50X1X3+1.94X1X4+2.13X2X3-4.19X2X4-0.88X3X4,提出了"安粳698"获得535.55kg/667 m2产量以上的优化方案,即栽插密度为1.823 4万～1.880 2万穴/667 m2,N施用量5.845～6.930 kg/667 m2,P2O5施用量8.239 5～9.760 5 kg/667 m2,K2O施用量11.605～13.21 kg/667 m2。各因素对安粳698产量的影响大小为施氮量>栽插密度>施钾量>施磷量。

| Abstract: | In order to explore the high-yielding cultivation techniques for Anjing 698,the quadratic regression general rotary combination design was used to study the relationship between yield and transplanting density,N,P,and K application amount and to establish yield mathematic model,Y=548.21-12.83X1-20.21X2+4.29X3+8.75X4+3.80X12-13.64X22-6.32X32-0.20X42-0.56X1X2+3.50X1X3+1.94X1X4+2.13X2X3-4.19X2X4-0.88X3X4.The optimum scheme of reaching 535.55 kg/666.7 m2 for Anjing 698 was(1.823 4 or 1.880 2)×104 hills/667 m2,5.845 or 6.930 kg/667 m2 N,8.239 5 or 9.760 5 kg/667 m2 P2O5,and 11.605 or 13.21 kg/667 m2 K2O.The order of factors influencing on yield of Anjing 698 was N>transplanting density>K>P. |
