摘要
对田间试验数据进行饱和D 最优设计统计得出 ,在当季气候条件下 ,施肥量 (X1)和灌水量 (X2 )对小麦亩产(Y)的回归方程Y =6 2 6 4.0 +384.8X1+4 14.8X2 - 6 16 .5X12 +72 9.8X2 2 +2 42 .2X1X2 ,最高产量点对应的施肥量和灌水量分别为 82 5kg/hm2 和 6 0 0 0mm ;施肥量 (X1)和灌水量 (X2 )对玉米亩产 (Y)的回归方程Y =5 77.8+5 33.7X1+2 2 8.0X2 +10 0 .8X12 - 338.1X2 2 +5 .6 4X1X2 ,最高产量点对应的施肥量和灌水量分别为10 5 0kg/hm2 和 42 5 4.0mm。
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.
