摘　　要：试验研究了保水剂与尿素的互作效应对玉米生长发育的影响,结果表明:保水剂与尿素的互作效应可以增加玉米的株高,叶面积,叶绿素含量,促进玉米根系的生长发育,提高玉米产量。要注意保水剂与尿素的用量,用量过多或过少,效果不明显,在试验中效果最好的处理是B2N2。In the experiment,the interaction effect of Super Absorbent Polymer and urea on corn growth were studied.Its result shows the interaction effect of Super Absorbent Polymer and urea can increase corn,s stem tall leaf area chlorophyll,promote the growth of corn,s roots,Increased corn yield.Should pay attention to the dosage of Super Absorbent Polymer and urea,use too much or too little,the effect is not obvious,Best treatment in the experiment is B2N2.
