| Abstract: | Carrying through the best design of the saturation D on the test data in the fields,we have drown a conclusion as follows from the statistical results. Under the climate condition of the year, the maths model of the wheat yield per mu (Y) about the supplying quantity(X-1) and irrigating amount(X-2) is Y=6264.0+384.8X-1+414.8X-2-616.5X-1+2+729.8X-2+2+242.2X-1X+2,that is to say ,the highest yield points of the X-1 and X-2 are respectively 825kg/hm+2 and 6000mm; the maths model of the corn yield per mu(Y) is similarly Y=577.8+533.7X-1+288.0X-2+100.8X-1+2-338.1X-22+5.64X-1X-2, the highest yield points of the X-1 and X-2 are respectively 1050kg/hm+2 and 4254.0mm. |
