摘要
通过饱和 - D最优回归设计田间试验测得的参数 ,建立了花生产量目标函数的密度 ( X1) ,N( X2 ) ,P2 O5( X3)三因素效应编码值回归模型 ,依此模拟得出亩产 >2 2 0 kg的优化栽培方案为 :每亩种植 9.375～ 10 .15千株 ,施纯氮 7.58～ 8.0 1kg,P2 O59.73～ 10 .84 kg。
According to the parameters obtained from field experiment which based on the satura- tion- D optimum regression design,effective regression model for peanut yield was estab- lished.Three influence elements for consideration were plant density(X1 ) ,nitrogen(X2 ) and phosphorus(P2 O5,X3) .Based on the obtained model,the best cultivation measures were set up,in which the plant density was from 9375 to 1 0 1 5 0 plants per m u ,pure nitrogen was from7.5 8to8.0 1 kilogram and phosphorus(P2 O5) was from9.73to1 0 .84kilogram.Single element effect and mutually effects were also discussed in the paper.
