甜柿枝梢开花结果特性研究

Study of Charactoristics of Blossom and Fruiting of the Branch in Persimmon

不同甜柿品种、不同枝梢类型,开花结果能力各不相同。一次梢段组成的梢其开花坐果率较低,除了利用极少数生长充实者短截补空外,其余应予以疏除;二次梢段组成的梢是坐果的主体,应尽量保留以增加坐果量;三次梢段组成的梢开花数较低,对此类梢的处理,可大年多留,小年少留,补空短剪,过密疏剪。

Blooming and fruitset ability are different due to persimmon varieties and branch types.The first branches develope few flower and has low fruitset rate,so it should be thinned except for several that should be short pruned to fill the empty. The second branches is main fruitset branch so it should be kept as to increase the number of fruitset.The third branches formates fewer flowers so it should be kept more in 'on year' and fewer in 'off year',and short pruned to fill the empty,or thinned if too thick.
