Abstract For the first time, this research enables a systematic parametric analysis of oat lodging to be undertaken. A generalised lodging model combining agronomy, biology and wind engineering has been used. Standard husbandry treatments have been deployed in order to ensure that the oat plants are grown in realistic conditions and to ensure that the results are widely applicable. It is shown that the drag area, which increases through the growing season as the oats become entangled, is the plant trait which influences both stem and root lodging the most. In addition (and consistent with other plants) stem yield stress and the number of stems per plant for stem lodging and the diameter of the root structure in the case of root lodging, are found to play an important role. It is also shown that there is a linear relationship between failure anchorage moment and the cube of the root diameter in oats. Moreover, monitoring the lodging in crops which were grown under different husbandry treatments revealed using a resistant variety coupled with low Nitrogen rates and low seed rates, whilst also applying a Plant Growth Regulator (PGR) can increase the resistance of oat against lodging.

校准的燕麦住宿模型与农艺测量比较

摘要 本研究首次实现了对燕麦住宿的系统参数分析。已使用结合农学、生物学和风工程的广义住宿模型。为了确保燕麦植物在现实条件下生长并确保结果广泛适用，已经部署了标准的畜牧业处理方法。结果表明，随着燕麦缠结，阻力面积随着生长季节的增加而增加，是对茎和根倒伏影响最大的植物性状。此外（并与其他植物一致）茎产量压力和每株植物茎倒伏的茎数和根倒伏情况下的根结构直径也起着重要作用。还表明，失效锚固力矩与燕麦根部直径的立方之间存在线性关系。此外，监测在不同畜牧业处理下种植的作物的倒伏，显示使用抗性品种以及低氮和低种子率，同时还应用植物生长调节剂 (PGR) 可以增加燕麦的抗倒伏性。
