【摘要】 为了促进甜樱桃品种美早2年生光秃主干萌发新芽,在定植2年的美早园中,选2种不同截头方式的小树为试材,研究了刻芽深度、刻芽时间及植物生长调节剂辅助3种刻芽处理对秃干萌芽的影响。结果表明:主干延长枝或侧枝被完全截掉的2年生秃干,3种刻芽处理之间的萌芽率差异不显著。但不管哪种方式的刻芽处理都比不刻芽显著提高萌芽率。更多还原

【Abstract】 In order to promote the new bud sprouting of bare trunk in two-year-old sweet cherry variety Tieton,we studied the effects of bud-notching depth,bud-notching time,and bud-notching combined with plant growth regulator application on the bud sprouting of sweet cherry bare trunks,whose tops were cut by 2 different modes(cutting off all branches on trunk,or reserving some one-year-old extension branches or lateral branches on trunk). The results showed that there was no significant difference in sprouting rate among 3 bud-notching treatments for two-year-old bare trunk without any branches. But all bud-notching treatments could obtain a higher sprouting rate than the control(no bud-notching).更多还原
