摘    要:在大田生产条件下研究了植物生长调节剂天达2116对冬小麦的产量和品质及生理特性的影响。结果表明,在适宜喷施浓度下,天达2116可显著提高冬小麦产量,改善冬小麦的籽粒品质及经济性状,促进灌浆期光合作用能力,利于光合产物的有效积累分配,但喷施浓度不当反而有负效应,从而最终影响产量潜力的发挥。故在对天达2116的实际应用推广中应注意其合理用量问题,本试验中,天达2116在拔期+孕穗期、灌浆期的喷施浓度为0.1%时获得最高的产量效益,为最适喷施浓度。

关 键 词:植物生长调节剂  天边2116  冬小麦  产量  品质  生理特性

Abstract:The effect of Tianda 2116 on winter wheat was studied under field condition.The results showed that Tianda 2116 could significantly increased yield,improved grain quality and economic properties,strengthened photosynthetic rate of grain filling period,and benefited the valid accumulation and distribution of photosythate only in case of proper spraying concentration,other wise it had negative effect,and therefore it influenced the yield and decreased economic profit.Thus attention shoud be paied to the concentration of Tianda 2116 in its practice use.The results suggested in this experiment that the highest yield and economic profit had been obtained with spraying concentration of 0.1% in jointing period,booting period and filling period.Therefore it was the most optimum spray concentration of Tianda 2116.
Keywords:Tianda 2116  Winter wheat  Yield  Quality  Physiological  Characters
