| 摘 要： | 本试验采用4因素5水平二次回归正交旋转组合设计方法,以大豆子粒脂肪含量为目标,种植密度及氮、磷、钾肥施用量为试验因子,研究了不同施肥量和种植密度对中晚熟大豆品种长农18脂肪含量的影响。建立了4项农艺措施与产量关系的数学模型,并解析了数学模型;指出了各因子的理想搭配模式及其适宜取值范围。从而得出了长农18高脂肪栽培措施的技术方案,为吉林省中部地区大豆高脂肪栽培提供了参考依据。 |

| Abstract: | Using four-factor and five-level quadratic rotational regression combination design and taking soybean fat as goal,taking density and application rate of nitrogen,phosphorus and potassium as research test factors,the influences of different fertilizer application and density of crop to the yield of the middle-late-maturing soybean cultivar ‘Changnong 18’has been studied in the experiment.The mathematical models of the fat and fertilizer application and density of crop have been established and analyzed.The ideal match pattern of various factors and their suitable value scope has been pointed out.The comprehensive cultivation measures for cultivation of high fat of soybean cultivar ‘Changnong 18’was obtained.This provided reference for high-fat soybean cultivation in the central region of Jilin Province. |
