新型生物菌肥对日光温室草莓产量影响及其数学函数模型的建立

通过二次正交旋转回归设计,探讨不同种生物菌肥对草莓的产量的影响.以这4种菌肥为决策变量,以草莓产量为目标函数,通过在乌兰察布地区日光温室作物草莓的试验地进行田间试验获得数据,建立了草莓产量与参数因子间的数学模型,得出了各因素与产量的主次关系和双因素搭配的产量效应.最后,通过计算机模拟寻优获得了在该实验地条件下的最高产量.草莓最高产量36861.54kg/667 m2的施肥方案：A（EM液体喷施）、B（绿康微液体喷施）、C（A50液体喷施）、D（A50粉末土壤施用）分别为：1.96 ～ 2.04g/L、1.927 ～ 2.073 g/L、0.71 ～0.790 g/L、1.3940 ～ 1.606 kg/667 m2.

Effect of Compound Biofertilizer Amount on Yield of Strawberry and Establishment of its Mathematic Model

Field experiment with the design of quadric circum - regression were performed to investigate the effects of Compound Biofertilizer Amount on yield of Strawberry. Four kinds of Biofertilize as decision variables, and taking the content of Strawberry - yield as target function , The mathematincs model between the Strawberry- yield and experimental facters is set up. The mathematics model gives out the main and secondary factors affecting the Strawberry - yield, and the Strawberry - yield response of double factors. Finally, the optimization scheme of Biofertilizer use for the maximum yield of Strawberry by using computer simulation in this experiment conditions is obtained. The maximum yield of Strawberry is 36861.54 kg / 667 m2. The fertilization scheme as follows ： A （ 1.96 - 2.04g/L ）, B （ 1. 927 - 2. 073 g/L ）, C（O. 71 -0. 790 g/L ） ,D（ 1. 3940 - 1. 606 kg/667 m2 ）.
