栽培措施对文旦柚果实品质的影响

目的]研究栽培措施对文旦柚外观和内在品质的影响,为文旦柚优质果品的生产提供参考。方法]研究树盘覆盖、疏花疏果、套袋处理对果实外观、裂果率、商品率、可溶性固形物含量、可食率、维生素C含量、含酸量等的影响。结果]疏花疏果处理能增加果实重量和可食率;套袋处理果实表面光滑、色泽均匀,病虫果和污染果显著减少,果实商品率增加。套袋处理的文旦柚商品率最高,疏花疏果的处理次之。疏花疏果和套袋处理的果实糖酸比略高,均为10.21,果实酸甜适宜。结论]果实套袋和疏花疏果处理对果实的商品性、产量和品质都有一定影响,生产上可结合这2种栽培措施来提高果实品质和商品性。

Effects of Cultivation Measures on the Fruit Quality of Wendan Pomelo

Objective] To study the effects of cultivation measures on the appearance and internal quality of Wendan pomelo to provide guidance for the production of high-quality fruits of Wendan pomelo.Method] The effects of blossom and fruit thinning, tree disk covering, and fruit bag-ging on the appearance, quality, rate of the cracked fruits, commodity rate, solid content, edible rate, vitamin C content, and acid content of Wendan pomelo.Result] Blossom and fruit thinning increased the fruit weight and edible rate;fruit bagging improved the smoothness and luster of the fruits and decreased the percentage of the spotted and polluted fruits , so the commodity rate of the fruits increased .The commodity rate of the bagged fruits was the highest, followed by the blossom and fruit thinning.Through blossom and fruit thinning and fruit bagging, the sugar-acid ratio of the fruits increased to 10.21, and the fruits were moderately sweet and sour.Conclusion] Blossom and fruit thinning and fruit bagging have certain effects on the commodity rate, quality and yield of Wendan pomelo, so the two cultivation measures can be combined to improve the commodity rate and quality in practice.
