采用二次饱和D—最优设计,建立了有机肥(普通农家圈肥)和无机肥(三料复合肥)与花生产量的数学模型。对模型进一步分析得:有机肥和无机肥均具有显著的增产作用,有机肥当茬增产效果小于无机肥,其最大增产值分别为727kg/hm2和1780kg/hm2;有机肥和无机肥具有一定的互补性,一种肥料用量增加,另一种肥料用量可适当减少,但仅单施其中一种肥料,不能充分挖掘花生的增产潜力;本研究的最优组合为:有机肥86400kg/hm2,三料复合肥924kg/hm2,最高产量可达7960kg/hm2;产量在6750～7950kg/hm2范围内的优化措施组合为:有机肥40620～98880kg/hm2,三料复合肥520.8～1454.4kg/hm2。
Based on the secondary saturation D-optimal design, a mathematical model of organic fertilizer (ordinary farm circle fertilizer) and inorganic fertilizer (three-compound fertilizer) and peanut production was established. Further analysis of the model shows that both organic and inorganic fertilizers have a significant increase in yield, organic fertilizer stubble yield increase is less than inorganic fertilizer, the maximum increase of 727kg / hm2 and 1780kg / hm2 respectively; organic and inorganic fertilizers have a certain Complementarity, an increased amount of fertilizer, another amount of fertilizer can be appropriately reduced, but only one of the only fertilizer, can not fully tap the yield potential of peanut; the optimal combination of this study are: organic fertilizer 86400kg / hm2, tris The compound fertilizer 924kg / hm2, the highest yield up to 7960kg / hm2; output in the range of 6750 ~ 7950kg / hm2 the combination of optimization measures: organic fertilizer 40620 ~ 98880kg / hm2, three compound fertilizer 520.8 ~ 1454.4kg / hm2.
