| 【目的】为掌握火龙果周年成花结果及市场价格规律以便制定出最优的产期调节方案,【方法】本研究以“桂红龙1号”红肉火龙果为对象,通过观测各批次花果的物候、单产、等级比例、批发售价等进行关联性分析,【结果】研究显示红肉火龙果全年可结果3个造次(结果周期),每个造次包括5～6个批次,在自然产期全年可结果13～15个批次,加上产期调节提早及延后批次周年可结果约18～20个批次；在自然产期单造产量峰高值与售价呈相反走向,7～8月成熟的批次同级别鲜果售价最低,且小果比例最高,大果比例越低。【应用范围】因此提出了火龙果周年产期调节要“抓两头、调中间”的基本策略,供生产者安排制定周年各批次的产期、产量生产计划方案提供参考依据。 |

| [Objective] In order to draw up a good plan for regulating off-season fruit set in Pitaya(Hylocereus undatus Britt＆Rose)which based on a analysis between seasonality of flowering fruiting and sales price , the study conducted a systematic observation to every batch of flowering and fruiting, yield, grades as well as wholesale price, then made correlation analysis among these facts. [Result] Results shown that red pulp Pitaya have 3 times fruits in a year with 5～6 separate batches/lots in a time which concludes 13～15 batches/lots in a whole year. We also found that in natural fruiting period, the sales price was reverse to the yield peek. Fruits ripening in July to August, the price was lowest in the whole year for the same grade fruit, and the proportion of small grade was the highest while big grade was the lowest. [Conclusion]Base on the analysis above, we suggesting a strategy for regulating off-season fruiting habit in Pitaya is early fruiting and delay fruiting than normal fruiting while staggered in normal fruiting period. |
