根据果树生产的需要,克服大小年,使果树年年稳产高产,又不损伤树体,陕西杨凌专家研制成功了果树成花素。大小年现象是目前红富士苹果生产中存在的严重问题。为了克服大小年,生产中多采用环剥、环切、拉枝以及疏花疏果等栽培管理措施,特别是环剥对成花很有效果。但多次严重环剥以后,会使树体衰弱,成果期缩短,结果受到影响。又由于环剥造成伤口,病菌容易侵入,易引起腐烂 According to the needs of fruit tree production, to overcome the size of the year, so that fruit trees steadily and yielding year by year, without damaging the tree, Shaanxi Yangling experts successfully developed fruit flori. Size year-round phenomenon is currently a serious problem in the production of Red Fuji apples. In order to overcome the size of the year, the production of more use of girdling, circumcision, pull branches and thinning and thinning and other cultivation management measures, in particular the stripping on the flower is very effective.
