Abstract:

It is very important to integration new variety and it’s cultural measures for increase production of crop, Qinghai No.12 was examined and approved ,which is larger seed variety of faba bean. In this paper Quadratic saturation D-best design wax used, which is fertilizer(x1), density(x2) and cut top(x3) is variable in the experiment. Through set up mathematic model between these variables and yield of Qinghai No.12, to analysis the influence effect of these variables to yield of Qinghai No.12 and decision-making the best collocation of the cultural measures, for provided the reference frame to set down the criterion of cultural measures of high yield for Qinghai No.12 in Faba bean.
