摘    要:目的]设计小麦拔节期和灌浆期喷施抗逆型植物生长调节剂处理试验,探索该调节剂对豫北麦区小麦产量及产量构成所产生的影响,为合理时期喷施提供理论依据。方法]采用随机区组设计,研究抗逆型植物生长调节剂对小麦农艺性状容重、分蘖数、产量、产量构成的影响。结果]拔节期喷施生长调节剂和拔节期+灌浆期喷施生长调节剂促进了小麦千粒重的增加,从而提高了籽粒产量;灌浆期处理小麦产量下降。结论]拔节期+灌浆期喷施生长调节剂的增产效果最好,该方式可推广使用。

关 键 词:抗逆型植物生长调节剂  拔节期  灌浆期  小麦  产量

Abstract:Objective] To design the treatment test of spraying stress-resistance plant growth regulator (SPGR) in wheat jointing stage and fill-ing stage,to explore the effects of this growth regulator on wheat yield and yield component in north Henan Province,and to provide theoretical ba-sis for the reasonable spraying stage.Method]Randomized block design was conducted to research the effects of SPGR on wheat agronomic char-acters,volume weight,tiller number,yield and yield component.Result] Spraying SPGR at jointing stage and jointing stage +filling stage pro-moted the increase of 1000-grain weight,and enhanced the grain weight;while wheat yield at filling stage decreased. Conclusion] Spraying SPGR at jointing stage +filling stage had the optimal yield-increase effects,and could be used for large scale extension.
Keywords:Stress-resistance plant growth regulators  Jointing stage  Filling stage  Wheat  Yield
