大樱桃的花芽量大,果小,疏花应结合花前和花期复剪进行。一般在3月底至4月中旬(河南地区)进行花前和花期复剪,此时,疏去树冠内膛细弱枝上及多年生花束状结果枝上的弱质花蕾、畸形花,以改善保留花的营养条件,有利坐果和果实发育。 由于大樱桃的多数品种自花结实率很低,为了确保产量,除了建园时配置好授粉树外,还应做好人工授粉和利用访花昆虫辅助授粉。
Large amount of large cherry flower buds, fruit small, thinning flowers should be combined with flowering and pre-scissors. Generally in the end of March to mid-April (Henan area) for the pre-flowering and flowering complex cut, this time, to the thinning of the crown and the weak branches on the bouquets of perennial bouquets of weak flower buds, deformed flowers, to improve the preservation of flowers The nutritional conditions, favorable fruit and fruit development. Due to the low self-inflorescence rate of most cherry varieties, in order to ensure the yield, pollination trees should be constructed in addition to the pollination trees in the park, pollination should also be done by artificial pollination and pollinators.
