| 摘 要： | 在膜下滴灌棉田,随灌水设置0,90,180,270,360 kg/hm2共5个N肥用量处理,观测不同N用量下棉花生长和干物质积累情况,尝试建立推荐施肥决策支持系统.结果表明:N 270 1g/hm2处理最好,施肥模型为y=3271.82 14.46x-0.0312x2(R=0.9604*),y籽棉产量,x滴灌棉田施N量.

| Abstract: | We intercalate 5 treatments of N dosage which is 0,90,180,270,360 kg/hm2,to obsere the crop's growth and the accumulated material of these treatments in the drip irrigation cotton field,and establish the recommendatory-decision system tried.The result shows that the treatment 270 kg/hm2 is the best and we got the return model of the seed cotton yield(y) and the nitrogen fertilizer dosage(x),which is y=3271.82 14.46x-0.0312x2(R=0.9604*). |
