摘要
运用二次回归旋转设计法，建立了３个可控栽培因子与银杏林下黄豆产量的数学模型。通过综合因素分析，提出了银杏林下黄豆种植的优化方案，为黄豆高产预控提供了信息。
The quadratic regression revolution design has been applied in the experiment and a group of mathematical models of three controllable factors and yield of soybean established in this paper .The analysis of complex of factors works out the optimixation version for soybean cultivation and data are provided for control in abvance of the crop for purposes of high yield.
