摘要
利用二次旋转正交回归设计研究了黑土区大豆花期配合施肥措施。通过田间试验测定参数 ,进行试验数据处理 ,建立产量函数模型 ,经计算机模拟寻优 ,筛选出最佳农艺措施组合方案 ,为大豆高产优质栽培的数量化、精准化提供了科学依据。图 4 ,表 2。参 5。
The measure of combined fertilizer application rate during soybean flowering in black soil were studied according to quadratic regression rotation design The yield function model was established based on parameters collected from field tests and treated data.The best agronomic measures were selected by using computer simulation.It provides a scientific basis for quantities and accuracy of high yielding culture in soybean.
