摘　　要：[目的]为探索不同共生期对晚播稻茬麦的生长和产量形成的影响,[方法]以宁麦13为试验材料,研究了0共生和短共生稻套麦对小麦生长特性和产量及其构成因素的影响。[结果]短共生期稻套麦(共生期15 d)会影响小麦植株生长、茎蘖动态和成穗。0共生稻套麦(共生期0 d)对植株生长无显著差异,其基本苗、茎蘖数和成穗数均比较稳定,较对照显著提高。此外,短共生期会增加不孕小穗数,降低千粒重,产量较对照仅增加了0.83%,但不显著。0共生显著改善了小麦穗部性状,小穗数、穗粒数和千粒重显著增加,不孕小穗数显著减低,产量较对照提高了6.67%。[结论]0共生稻套麦是在晚播条件下较短共生稻套麦和常规栽培好的一种高产应变栽培技术。[Objective]To explore the effects of different symbiotic periods on the growth and yield formation of late-sowing wheat after rice.[Method]With Ningmai 13 as the research materials,we researched the effects of 0-symbiotic and short-symbiotic rice interplanting wheat on the growth characteristics,yield and its components of wheat.[Result]The short symbiotic rice interplanting wheat( symbiotic period 15 d) could affect the growth,tiller dynamics and panicle formation of wheat.The 0-symbiotic rice interplanting wheat( symbiotic period 0 d) had no significantly influence on growth of wheat.The number of basic seedlings,tillers and panicles of wheat were stable,which were significantly increased compared with the control.In addition,the short symbiotic period rice interplanting wheat increased the number of sterile spikelets and decreased1 000-grain weight,and the yield increased only by 0.83% with no significance when compared with the control.However,the 0 symbiosis rice interplanting wheat significantly improved the ear traits of wheat,spikelet number,grain number per spike and 1 000-grain weight,and its number of sterile spikelets decreased significantly,finally the yield increased by 6.67% compared to the control.[Conclusion]The 0 symbiosis rice interplanting wheat was a better way of high yield emergency cultivation technique when compared with the short symbiotic rice intergrowth wheat and conventional cultivation under the condition of late sowing.
