摘　　要：以"巴莱姆"为试材,研究U形双干整枝方式对越冬茬辣椒的植株生长、光合特性和产量的影响。结果表明:采用U形整枝技术,对植株进行拉枝定型,在生长前期可控旺促壮,根系生长发育明显增强,根系活力增加15.44%;叶片叶绿素含量、净光合速率增加,上层和下层叶片的叶绿素含量分别比CK高3.47%、3.46%,净光合速率分别比CK高1.58%、7.92%;盛果期、后期的增产效果显著,总产量比CK增加993.69 kg/667 m^(2),增产7.34%。The effect of U-shaped double stem pruning on the growth,photosynthetic characteristics and yield of pepper in winter was studied with"Ballem"as experimental material.The results showed that the growth and development of the root were enhanced obviously,and the chlorophyll content and net photosynthetic rate of leaves increased when the U-shaped pruning technique was used to keep double stem shape,and the root activity increased by 15.44%in the early growth stage.The chlorophyll contents of upper and lower leaves were 3.47%and 3.46%higher than control,respectively.The net photosynthetic rate was 1.58%and 7.92%higher than control,respectively.Yield of the total yield increased 993.69 kg/667 m^(2),7.34%compared with control.
