巨峰葡萄为我省近年来引进的良种,在光照好、温度高的地区,一次果蔓短截促当年冬芽萌发,能结出优良二次果,甚至三四次果。盆地西南地区光照少,温度较低,巨蜂葡萄当年冬芽不易萌发,即使少数萌发结出二次果也不易成熟,果实小、青、酸、硬,经济价值很低。故生产上很少利用二次果。两年来,我们在夹江、乐山等地对巨峰 Kyoho grapes for the introduction of the province in recent years, the fine varieties of well-lit, high temperature areas, a cranberry short cut when the winter buds germination, can produce excellent secondary fruit, or even 34 fruit.

Even a few germinated secondary fruits are not easy to mature. The fruits are small, green, sour and hard with low economic value. It is rarely used in the production of secondary fruit.
