Abstract:
With a regression design this study deals with the quantitative technical measures irrigation frequency and dates,weight of seeds sown per hectare,(rate of seeding),application of manure and chemical nitrogen and phosphorus fertilizers in relation to the yield of spring wheat grown in irrigated fields in the Yanbei Prefecture of Shanxi Prowince and financial income.Through multipoint test,various mathematical models of eco-systems of wheat fields have been obtained.After application on a small scale and comparison in 1986 and 19g7,the optimization plans proved to be feasible and profitable.
