小麦倒伏是品种、栽培措施以及环境条件综合影响的结果.抽穗灌浆阶段受暴风雨的袭击,则是南方冬麦区造成小麦倒伏的重要外部因素.一般认为,倒伏越早减产越严重.但是,不同时期倒伏对小麦产量及其构成因素影响的系统研究尚少.本试验目的,在于通过人工模拟倒伏,明确不同时期倒伏对小麦地上部诸性状、干物质积累、产量及其构成因素的影响,为制订小麦高产栽培技术措施提供参考资料.
The lodging of wheat is the result of the combined effects of varieties, cultivation measures and environmental conditions.The storm attack on the heading stage of filling stage is an important external factor that causes the wheat to lodging in the winter wheat area of the South China.It is generally believed that the sooner the lodging is reduced, the more serious it is.However, Systematic research on the effects of period lodging on wheat yield and its components was still scarce.The purpose of this experiment was to find out the effects of lodging at different periods on the traits, dry matter accumulation, yield and its components of wheat by artificial lodging Development of high-yielding cultivation techniques and measures to provide reference materials.
