环割、环剥和绞缢对甜樱桃幼树叶面积和成花的影响

Influences on flowerbud differentiation and leaf area of young sweet cherry trees treated with girdling,band girdle,and tying with rope

甜樱桃采用环割、环剥、绞缢等促花措施处理,结果表明,不同的处理时期对甜樱桃叶面积、新梢数、花枝百分率的影响不同,短枝停长期的各处理中,环割一道的新梢总叶面积较大,新梢数中等,花枝百分率最高;中梢停长期各处理中,以环剥不包伤口处理的促花效果最好.

Influnces of girdling, band girdle, and tying with rope on leaf area, number of shoot and flowerbud differentiation of young sweet cherry tree were observed. Effects on leaf area, shoot number and flowerbud differentiation with the treatment of girding once were evident when short shoots stop growing . when long shoots stop growing, the treatment of band girdling 2 mm with wound barely reached best result of flowerbud-inducing.
