| 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 Province and financial income. Through multi-point test, various mathematical models of ecosystems of wheat fields have been obtained. After application on a small scale and comparison in 1986 and 1987, the optimization plans proved to be feasible and profitable. |
