摘要
采用5因素二次回归正交旋转组合设计的试验方法,研究了夏花生产量与有机肥、氮肥、磷肥、钾肥和石膏施用量的关系及其5项施肥因素之间的交互作用,建立了产量目标性状技术模式。通过模拟寻优,筛选出了6000kg/hm2以上夏花生荚果产量的优化施肥方案:有机肥62115.0～65745.0kg/hm2,氮肥(N)219.2～237.9kg/hm2,磷肥(P2O5)133.1～144.7kg/hm2,钾肥(K2O)57.8～75.6kg/hm2,石膏(CaSO4)186.8～202.7kg/hm2。
Using the five factor two return orthogonal revolving unitized design testing method, we research the relations among the summer peanut output and the organic fertilizer, the nitrogenous fertilizer, the phosphate fertilizer, the potassium fertilizer, the gypsum employment quantity. We research the factor correlation between the five items apply fertilizer. Then we established the output goal character technology pattern. Through the simulation optimization, we screened apply fertilizer the plan that the summer peanut pod output above 6000 kg/hm^2 the organic fertilizer is 62115.0-65745.0 kg/hm^2, the nitrogenous fertilizer（N） is 219.2-237.9 kg/hm^2, the phosphate .fertilizer（P2O5） is 133.1-144.7 kg/hm^2, the potassium fertilizer （K20） is 57.8-75.6 kg/hm^2, the gypsum employment（CaSO4） is 186.8-202.7 kg/hm^2
