| 摘 要： | 以播种量(x1)和氮(x2)、磷(x3)、钾(x4)肥施用量为研究对象,采用4因子5水平二次旋转回归组合设计,对高产抗病小麦丰优3号的高产栽培技术进行试验,建立了各因素与产量指标的数学模型y=305.75 11.67x2 14.5x4-9.270 83x22-8.02x24。综合得到丰优3号丰产栽培配套技术措施的优化组合是:施用2 000 kg/667m2农家肥作底肥的基础上,播种量6 kg/667m2,氮施用量22.5 kg/667m2,钾施用量30 kg/667m2,不施磷肥,产量可达314.63 kg/667m2。

| Abstract: | The orthogonal rotation regression design of 4 factors(seed quantity x_1,nitrogen x_2,phosphorus x_3and potassium x_4) was used in Fengyou 3,a wheat variety with high yield and resistance to establish the mathematical model between yield and 4 factors.That is,y=305.75 11.67x_2 14.5x_4-9.27083x2_2-8.02x2_4.The optimum combination cultivation technique for 314.63 kg/667m2 includes 6 kg/667m2 of seed quantity,22.5 kg/667m2of nitrogen and 30 kg/667m2 of potassium based on 2 000 kg/667m2 of farmyard manure. |
