促花措施对日光温室甜樱桃幼树成花及坐果的影响

Influences on Flowerbud Differentiation and Fruit Setting of Young Sweet Cherry Trees Treated With Flowerbud-inducing Methods in Solar Greenhouse

日光温室中甜樱桃采用刻芽、环剥、绞缢、PP333 等促花措施处理 ,促花效果以环剥后不包伤口、绞缢、短梢停长期低浓度PP333 喷布和中长梢停长期高浓度PP333 蘸尖效果较好。日光温室中甜樱桃可多次分化花芽 。

Brow-incising, band girdling, tying with rope and treating with PP333 were used to promote flowerbud differentiation in sweet cherry. The flowerbud-inducing effects were evident with the treatments of band girdling 2mm with wound barely, tying with rope, treating with PP333 in lower concentration when short shoots stop growing and in higher concentration when mid and long shoots stop growing. Flowerbuds differentiation of sweet cherry could occur many in solar greenhouse, and the flowerbuds formed later had a higher fruit setting percentage.
