六叶期叶面喷施聚糠萘合剂处理后,春玉米灌浆期及籽粒形成期茎秆抗倒伏能力得到明显增强,茎皮厚度、茎秆直径及单位节间长度干物重显著提高。同时玉米穗部性状优化,秃尖变短或消失,百粒质量显著增加,百粒体积增大,穗长提高,穗质量增加,产量提高。以上结果表明,化学调控处理可以有效的提高春玉米的茎秆质量强度,在东北地区特定气候下实现丰产性与抗倒伏性的协同表达。
Six-leaf foliar application of poly-furfur naphthalene mixture treatment, spring maize grain filling stage and grain lodging resistance was significantly enhanced stem bark thickness, stem diameter and unit internode length dry weight was significantly increased. At the same time, the characteristics of ear in maize were optimized, the bald tip became shorter or disappeared, the quality of 100 grains increased significantly, the volume of grains increased, the spike length increased, the ear quality increased and the yield increased. The above results show that the chemical regulation and treatment can effectively improve the quality of spring corn stalks, in the Northeast climate to achieve high yield and lodging synergistic expression.
