摘　　要：采用五因素二次回归旋转组合设计，建立了川西、川东２个不同生态区杂交稻制种稻粒黑粉病病粒率和产量的数学模型，并模拟推导了优化农艺方案。The quadratic regression revolution design with five factors was adopted to estahlish twomathematical models for the rate of kernel smut一infected seeds and paddy yield for the twodifferent ecological regions of eastern and western Sichuan. Simulated optimized agrotechiqueschemes were obtained.
