| 摘 要： | 从植株形态、生物力学特性、茎秆解剖形态等方面研究包衣处理与根部抗倒性、茎秆抗倒能力的关系,分析种子包衣处理对夏玉米抗倒性能的作用效果.结果表明,种衣剂可促进植株生长,使干物质积累量增加,根系发育较早,根条数增加；促进茎秆内部维管束和机械组织发育；茎秆含钾量增加,有利于抗拉力、抗折力、茎秆穿刺强度增加；可以提高植株抗倒能力从而增加产量.

| Abstract: | The effect of seed dressing on stem resistance of summer maize(Zea mays L.) were studied. Plant morphology, mechanical characteristics and anatomical characteristics were investigated to analyze the action of seed dressing on root and stem lodging resistance. The results showed that seed dressing treatment was conductive to growth and lodging resistant development in maize, which was mainly manifested as an overall positive increase of lodging rates. These characteristics included dry matter, root number, width of outer vascular bundles group, width of cuticular tissue and potassium content of the 3rd internode and bending resistance, breaking resistance, hardness. Seed dressing might have an effect on improving the lodging resistance for certain types of varieties and thus enhance yield of summer maize. |
