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。[ Objective] To design the treatment test of spraying stress-resistance plant growth regulator （SPGR） in wheat jointing stage and filling stage ,to explore the effects of this growth regulator on wheat yield and yield component in north Henan Province ,and to provide theoretical basis for the reasonable spraying stage. [ Method] Randomized block design was conducted to research the effects of SPGR on wheat agronomic characters, volume weight,tiller number, yield and yield component. [ Result] Spraying SPGR at j ointing stage and jointing stage ＋ filling stage promoted the increase of 1 000-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.
