摘要
采用盆栽试验研究抗旱剂对玉米生长及产量的影响,结果表明:抗旱剂可使玉米苗期株高降低,叶片增加,根数减少,根长增加,最终使玉米生育期缩短,提前成熟;应用抗旱剂能够增加苗期土壤含水量;抗旱剂能够有效增加玉米的产量。
Effect of drought-resistant chemical on growth and yield of corn is studied by potted plant experiment, the result showed that drought-resistant chemical has significant effect on growth of corn, such as plant height decrease in seedling stage, leaf number increase, root number decrease, and root length increase, all of these changes result in growth period of corn was reduced. And drought-resistant chemical can increase water content of soil in seedling stage and corn yield effectively.
