摘要
盆栽条件中度水分胁迫下,在玉米大喇叭口期用各抗旱剂叶面喷施处理,研究胁迫期间和恢复供水后植株的形态特征。结果表明,经不同抗旱药剂处理后的玉米植株形态结构和抗旱生理指标方面表现出不同的差异。证明大喇叭口期喷施处理中,旱地龙处理显著提高了两个玉米品种的单株产量。
Under moderate water stress and potted plant condition, spraying treatment with drought-resistant agent was carried out at corn big trumpet period to study the plant morphological characteristics during stress period and after water supply. Result showed that after the treatments with different drought-resistant agents,differences in corn morphological characteristics and physiological index of drought resistance were observed. It was proved that Handilong treatment significantly improved the single plant yield of two corn cultivars during the spraying at big trumpet period.
