金冠、短枝型国光4—6年生幼旺树,其1年生强壮枝易在秋梢上形成腋花芽,但这些腋花芽发育质量差,座果率极低。据我区连续3年调查表明,其花序座果率,金冠平均不足15％,短枝型国光仅5％;而且这些腋花芽开花比顶花芽晚,座住的果实普遍发育较小。自1989—1991年连续3年,我们对金冠、短枝型国光两品种的1年生强壮枝分别进行秋季拉枝到80—90度+9月中旬摘心和对
Golden crown, spur type Guoguang 4-6 years of vigorous tree, its annual strong branches easy to form axillary buds in the autumn tip, but these axillary buds poor quality of development, fruit set rate is very low. According to my area for three consecutive years survey showed that the inflorescence fruit rate, the average crown less than 15%, spur-type light only 5%; and these axillary bud flower bud later than the top, the seat of the fruit generally less developed. Since 1989-1991 for three consecutive years, we have the golden crown, spur-type Guoguang two kinds of strong annual branches of two branches in autumn pull branches to 80-90 degrees + mid-September topping and
