摘　　要：为了探讨小麦(Triticum aestivum L.)高产新技术——新型植物调节剂的使用效果,选用不同叶面肥及其助剂于小麦灌浆始期进行叶面喷洒试验。结果表明,小麦灌浆速度呈多元回归;各施肥处理的成穗数、穗粒数之间差异均不显著(P>0.05),但产量与千粒重间差异极显著(P<0.01),其中以喷洒叶面肥阿尔比特+锌的处理千粒重和产量最高,对照(喷施磷酸二氢钾处理)次之,其他处理的千粒重和产量均低于对照。In order to study effects of the foliage as a new type of plant growth regulators on yield components and yield of wheat, experiments of spreading different leaf fertilizers and its additives at the initial stage of grain filling of wheat were carried out. The results showed that the speed of wheat（Triticum aestivum L.） filling rate was multiplely regressed. The yield components and yield analysis showed there was no significant（P 0.05） difference of panicles and grains among different treatments. Thousand grain weight and yield of treatments was significantly different（P0.01）. Among which, Albit ＋ Zinc had the highest thousand grain weight and yield, folleowed by the treatment of monopotassium phosphate. The thousand grain weight and yield of other treatments were lower than that of the control.
