摘　　要：采用5因素二次回归正交旋转组合设计试验方法,研究了影响直播夏花生产量的有机肥,N,P2O5,K2O和石膏因素与产量的关系及交互作用,建立了产量目标性状函数模型.通过模拟寻优,筛选出了6000kg·hm-2以上荚果产量的优化施肥方案.By the designing of five-factor quadratic regression orthogonal rotation cross,studies were conducted on the relationship between yield and the five factors organic fertilizer,N,P_2O_5,K_2O and gypsum,influencing the yield of direct sowing summer peanut and their interaction.And the functional model of the goal of yield and property was established .Through simulated optimization,the optimizing ferlilization project was screened for the pod yield over 6 000 kg·hm^(-2).
