台湾甜脆桃留果量试验初报

Preliminary Study on Fruit Keeping Amount of Taiwan Crispy Peach

以台湾甜脆桃为试材,探讨了不同留果量对产量、品质的影响,结果表明：随着留果量的增加,单株、单枝产量显著提高,但果个变小,可溶性固形物含量降低;兼顾产量和品质,成年树单株目标产量、单果重分别以15kg左右、80～100g为宜;单株留果量应控制在150 ～200个,短果枝适宜留果量为1个、中果枝1～2个、长果枝2～3个.

Effects of fruit keeping amount on output and quality of Taiwan crispy peach were studied. The results showed that, increasing fruit keeping amount obviously increased the output per plant and per branch, but decreased the soluble solid content and the size of fruit. Taking the consideration of both output and quality, for the adult tree, the suitable target output per plant should be 15kg and single fruit weight should be 80 to 100g, the optimal fruit keeping amount for single plant should be 150 to 200, and I for short frait branch, 1 to 2 for medium fruit branch, 2 to 3 for long fruit branch.
