摘要
通过室内模拟试验和玉米盆栽试验,研究了5种保水剂对土壤蒸发量和玉米幼苗抗旱性的影响。结果表明,保水剂能够降低土壤表面的蒸发量,其中以保定“科翰98”高效抗旱保水剂处理的总蒸发量最小,比对照降低了8.95%,效果最显著。保水剂的施用有利于增强玉米的抗旱性,施用保水剂使细胞质膜透性、过氧化氢酶的活性、丙二醛含量和脯氨酸含量降低,其中以保定“科翰98”效果最佳。
Experiments were conducted to study the effects of super absorbent polymers on soil evaporation and drought resistance of corn seedlings. The results obtained were as follows: the super absorbent polymers decreased evaporation from soil surface and improved the drought resistance of corn seedlings.
