摘要
[目的]明确不同因素对冬小麦抗倒伏性的影响，为今后冬小麦生产提供科学依据。[方法]调查测定国家旱地区域试验13个新品系株高、茎粗、第一节间长度、第二节间长度、茎秆二氧化硅含量。[结果]科遗12－6105、中麦39、太1305、长7080、长6990、众信5158、临旱5115这7个供试品系的抗倒伏性优于其他品系。[结论]培育矮秆、粗茎，第一、第二节间较长及第一、二节间二氧化硅含量较高的品种是预防倒伏的主要途径。
Abstract
Objective] To determine effects of different factors on winter wheat lodging resistance and provide scientific basis for winter wheat production.[ Method] The plant height, stem diameter, section 1 length, section 2 length, silica content of 13 new lines in dryland were in-vestigated.[Result] The lodging resistance of Keyi12-6105,Zhongmai39, Tai1305, Chang7080, Chang6990, Zhongxin5158, Linhan5115 was better than other lines.[Conclusion] Cultivating lines with short, thick stem, longer section length between section 1 and 2, higher silica content is the main way to prevent lodging.
