小麦抗倒伏研究进展

Research Progress on Lodging Resistance of Wheat

小麦倒伏发生后对生产影响极大,因此小麦抗倒性不仅是育种研究的突出问题,同时也是栽培研究的热点。造成小麦倒伏的影响因素有多种,如大风、病虫害、品种、播期、密度、水肥管理、化学调控等,评价指标也涵盖形态、结构、成分、生理学以及衍生出的数学模型等方面,部分学者也据此对部分小麦的抗倒性进行了评价。对近年来小麦抗倒性方面的研究进行了系统总结,并对未来的研究方向提出了建议。

The occurrence of lodging in wheat has a great impact on wheat production,which is not only a prominent problem in breeding,but also a focus of cultivation research.There are many factors that affect lodging of wheat,such as strong wind,diseases and insect pests,variety,sowing date,density,water and fertilizer management,chemical regulation and so on.The evaluation indexes also cover many aspects such as morphology,structure,composition,physiology and derived mathematical models.Some scholars also evaluated the lodging resistance of wheat.This paper summarized the research on wheat lodging resistance in recent years,and suggestions for future research directions were also given.
