摘要: 试验应用311-A拟饱和最优回归设计,研究PAA、PAM、补水量对旱作区玉米产量的影响。结果表明:单因素对玉米产量的影响为PAM〉PAA〉补水量:两因素互作对玉米产量的影响为PAA+PAM〉PAM+补水量〉PAA+补水量。经模拟寻优表明.最优组合为PAA为51kg/hm^2,PAM为36kg/hm^2,补水量为0.302L/穴,拟获得的最高产量为7845.45kg/hm^2。

Abstract: Effects of PAA ,PAM and additional water amount on corn yield in arid area were studied through 311-A application of optimal fitting saturated regressive design. The results showed that the effect of single factors on corn yield was: PAM〉PAA〉 additional water amount;the effect of interaction two-factor on corn yield was: PAA+PAM〉PAM+additional water amount〉PAA+ additional water amount.The results after simulated optimization showed the optimal combination was that the PAA was 51kg/ hm^2,PAM was 36kg/hm^2 and additional water amount was 0.302L/point,the yield was 7845.45kg/hm^2.
