| 摘要: |
| 抗倒伏能力的合理评价在玉米生产中非常重要。为了解当前国内外玉米抗倒伏能力常用的评价方法(茎秆质量评价、根系评价、田间风洞测试和田间原位测试)及其相关仪器设备的研究进展，基于中国知识资源数据库(CNKI)和国家知识产权局专利检索数据库，以“玉米”、“抗倒伏”为关键词，检索了1990—2020年文献资料，进行归纳和总计，并比较分析了不同评价方法的相对优势和改进方向。结果表明:1)田间原位无损测试能够模拟不同风速下的植株受力情况，测试效率高且使用成本低，在玉米抗倒伏能力评价中具有较好的应用前景；2)明确单株与群体、生物力学与实际风速的关系，通过单株的抗倒伏力的实时动态变化去反映群体抗倒伏力，是未来玉米抗倒伏能力评价的发展方向；3)研制田间原位无损测试专用仪器，结合多年、多点、多生态区、多气候条件田间测试，建立原位无损定量评价指标体系，制定技术标准，是未来玉米抗倒伏能力无损评价的重要研究内容。本研究进展综述可为玉米抗倒伏能力的合理评价及为田间原位无损测试植株抗倒伏仪器的研制和应用提供依据。 |

| Abstract: |
| A rational evaluation of lodging resistance is of great importance to maize production. The aim of this study was to understand the current research progress of evaluation methods(stem quality evaluation, root system evaluation, field wind tunnel test, and field in-situ test)and their related equipment to determine maize lodging resistance. We compiled existing available studies with “maize” and “lodging resistance” as keywords in China Knowledge Resource Database(CNKI)and patent search database of China National Intellectual Property Administration from 1990 to 2020. Data were summarized and analyzed to assess the relative advantages and improvement directions of different evaluation methods. The results show that 1)Field in-situ non-damage testing method does well in simulating the stress of maize plants under different wind speeds and should be widely used due to its higher efficiency and lower cost; 2)Relationships between individual plants and community and between biomechanics and actual winds should be clarified for better evaluation on the lodging resistance, and then the real-time changes in the lodging resistance of individual maize plants can reflect their substantial responses at the community level; 3)The development of specific instruments for in-situ nondestructive testing and the establishment on a quantitative evaluation index system based on data collection from field tests at different temporal and spatial scales are highlighted in the future. The observations in our review can provide technical support for the reasonable evaluation of lodging resistance in maize and for the development and application of in-situ non-damage testing in the field. |
