摘要
倒伏一直是限制小麦高产稳产的关键因素,化学调控是一种有效降低倒伏风险的策略。喷施化控防倒剂(Chemical anti-lodging regulators,CARs)能够控制小麦生长,提高茎秆强度,预防倒伏。然而针对小麦高产栽培中化控抗倒伏的研究及应用还未有较全面的综述。因此本文收集整理了我国现有登记的小麦抗倒伏CARs,总结了不同CARs的特点、功效及其对小麦茎秆结构与组成、根系、冠层结构、作物生产力及品质的影响,并以高产抗倒为目标,总结了不同CARs在实现小麦高产抗倒协同提升的适宜施用时期。此外,本文全方面汇总了与CARs配套的小麦抗倒伏栽培管理措施(耕作方式、适宜密度、营养水平与水分管理),小麦抗倒伏评价方法及CARs对关键指标的影响,并展望了CARs在小麦抗倒伏高产栽培中的研究方向,旨在为促进小麦的高产、稳产提供精准调控措施及理论支撑。
Lodging has always been a key factor limiting the high and stable yield of wheat.Chemical anti-lodging regulator is an effective strategy to reduce lodging risk.Chemical anti-lodging regulators(CARs)spraying can control wheat growth,improve stem strength,and prevent lodging.However,the research and application of chemical control and lodging resistance in wheat high-yield cultivation have not been comprehensively reviewed.Therefore,this paper collected and sorted out the wheat CARs registered in China,summarized the characteristics,efficacy and effects of different CARs on wheat stem structure and composition,root system,canopy structure,crop productivity and quality,and summarized the suitable application period of different CARs in realizing the synergistic improvement of wheat yield and lodging resistance with the goal of high yield and anti-lodging.In addition,the management measures of wheat lodging resistance(tillage mode,suitable density,nutrient level and water management),evaluation methods of wheat lodging resistance and the influence of CARs on key indicators were summarized.The research direction of CARs in wheat anti-lodging high-yield cultivation was prospected,aiming at providing precise control measures and theoretical support for promoting wheat high-yield and stable yield.
