- 利用田间试验获得的参数,通过计算机使用旋转设计试验数据处理程序,建立了大豆新品种合丰39高产数学模型,解析了试验因素的产量效应及其交互作用,并优选出了最佳农艺措施组合方案,确定了置信区间,为其高产栽培提供参考依据。
- Abstract:
- A high- yield mathematical model of New Soybean cultivar Hefeng 39 Was setup w ith gyrating desig n. The model not only rev eals the yield- effect of th ree ag ronomic measures and their alterna tive ef fect , but also can be used to deduce the highest theo retical yield under the ex perinent ’s conditions, and provide abundant info rmation for desig ning the best measure of soybean production. Amo ng sy nthetic measures, the o rder of three ex periment ’s facto rs of agricultural measures according to their cont ributions to yield is: fertilizer> sowing date> density. Searching for the optimization of the model with the computer, w e assume the step is one, 125 designs are composed of th ree factors and fiv e levels. Yields of 51 desig ns reache more than 175kg /mu. By analysis, the best ag ronomic measures desig ns can be w orked out and is listed below: densi ty 12700~14800 plants /mu; fertilizer 14. 24~19. 6kg /mu; sowing date 9th May~15th May.
