摘　　要：以"蒙山红"为试材,在定植后翌年春天对其分别进行0°(CK)、70°、接近90°主干拉枝,研究主干拉枝对山楂枝类特性及结果性能的影响。结果表明:接近90°主干拉枝的山楂枝量、结果枝枝量、花量、坐果量最多,70°主干拉枝的山楂中短枝比例及中长结果枝比例最大。To explore the effect of trunk-bending on branch characteristics and fruit setting performance of‘Mengshanhong＇hawthorn,we did three treatments on its trunk that were 0°,70°,nearly 90°bending angle at the next spring after planting.The results showed the hawthorn which trunk under nearly 90°bending angle was superior to other treatments at the amount of branch and fruiting branch,inflorescence and fruiting inflorescence,flower and fruiting flower;the percentage of middle and short branch,the percentage of middle and long fruiting branch of the hawthorn which trunk under 70°bending angle were higher than others.
