In order to compare the characteristics of different varieties of sweet cherry and to formulate corresponding pruning scheme, hierarchical cluster analysis was conducted for the 14 sweet cherry varieties that were mainly planted in Shanxi Province. The results showed that the 14 varieties of sweet cherry could be divided into two types, Hongmanao and Rainier. Fruit setting rate, branching rate, medium fruit shoot proportion, spur proportion and yield per plant were significantly different between these two types of sweet cherry. The key points of pruning management, to improve the yield of Rainier type, were to increase the fruit setting rate and spur proportion, and to control properly the long and medium fruit shoot proportion.
扁桃(Amygdalus communis L.)属蔷薇科李亚科桃属扁桃亚属植物。扁桃营养和医药价值丰富,且其理化性状好,还可被广泛用作工业防锈油和化妆品生产原料;同时,扁桃的适应性强,抗寒耐干旱,是退耕还林,荒山绿化的首选树种。基于此,仅就扁桃的产业化生产基地规划,栽培技术等内容进行论述,以期为扁桃产业良性发展提供参考。
