Lodging in rice

As growers push for maximum grain yield, lodging is becoming a significant factor in rice production, increasing the time and cost of harvest and often resulting in significant yield loss andreduced grain quality.Several factors influence lodging susceptibility including seasonal weather, variety, sowing method, nitrogen rate and timing, plant density, water depth, time of draining and wind or rain as the crop nears maturity. Some of these factors can be managed, thus providing the opportunity to reduce crop lodging potential.

随着种植者追求籽粒最高产量，倒伏已成为水稻生产中的关键制约因素：它不仅延长了收获作业时长、增加了收获成本，还往往造成显著的产量损失与籽粒品质下降。诸多因素会影响水稻的倒伏易感性，包括季节性气象条件、品种特性、播种方式、氮肥施用量与施用时期、种植密度、田间水深、排水时机，以及作物临近成熟阶段的风雨影响。其中部分因素可通过人为调控手段进行干预，从而为降低作物倒伏风险提供可行途径。
