| 摘 要： | 根据花生氮、磷、钾"3414"田间试验测得的数据,建立以花生产量为目标函数的7类回归模型,通过对各类模型提供的施肥信息及产量期望的经济效益分析,以氮磷二元二次回归模型(钾肥固定于2水平)提供的施肥决策:施纯氮91.73 kg/hm2、五氧化二磷137.60kg/hm2、氧化钾90.00 kg/hm2,花生产量期望4 555.01 kg/hm2,产投比21.20,作为新乡市西部地区花生生产的推荐施肥量。

| Abstract: | According to peanut NPK 3414 field test data,7 fertilizing effect models were set up taking peanut yield as the target function.Effect analysis of fertilizer amount and the corresponding yield had been carried out to take the fertilizer formula,which was given by NP binary quadratic regression model(K2O at 2 level),i.e.pure N 91.73 kg/hm2,P2O5 137.60 kg/hm2,K2O 90.00 kg/hm2,peanut yield expectation could reach 4 555.01 kg/hm2,the ratio of output to input was 21.20.This formula can be recommended to this cit... |
