| 中文摘要: |
| 饲草燕麦是我国重要的优质饲草，然而，倒伏是限制燕麦饲草高产、稳产和优质的主要原因之一。本文系统整理、分析了国内外相关文献，综述了倒伏对燕麦生产的影响，倒伏降低燕麦营养物质积累和种子产量、降低燕麦草饲用价值和贮藏品质。分析了影响燕麦倒伏的因素，主要包括燕麦形态特征、茎秆力学特性、木质素代谢等内在因素，以及自然条件、栽培措施等外界因素。总结了田间观察法、人工模拟法、模型综合评价法等评价燕麦倒伏性能的方法，并从燕麦抗倒伏关键性状筛选、抗倒伏品种培育及高产栽培措施优化等方面做了展望，旨在为我国燕麦抗倒伏性相关研究和实际生产提供参考。 |
| 英文摘要: |
| Oat is an importantly high-quality forage in China. However, lodging is one of main factors limiting the high and stable yield and premiumization of oat forage. This review systematacially collates and analyzes the related literatures around lodging home and abroad. We review the influence on oat forage production of lodging, which decrease nutrient accumulation, seed yield, feeding value and storage quality. The factors affected lodging are analyzed, including internal factors of morphological characteristics, mechanical property of stem, lignin metabolism and external factors of natrual conditions and cultivation practice in planting area. We summary the evaluation oat lodging methods including field observation, manual simulation and simulated comprehensive evaluation. We outline that oat lodging is able to be eased by selecting key characteristics of lodging-resistant, breeding lodging-resistant cultivars and optimizing cultivation practice, aiming at providing references for studies on oat lodging and practical production. |
