摘要:

近年来设施火龙果栽培在浙江发展迅速,但浙江冬春季节保护地栽培仍受到低温、弱光等不利因素的影响,往往会导致光合速率偏低,严重影响火龙果商品性和农民经济效益。本研究以火龙果品种红水晶作为研究材料,设置3种不同浓度新型光合作用促进剂(TiO2)处理和1个对照组。果实成熟时,测定火龙果外观物理性状和品质性状。 结果显示,稀释1 500倍处理改善火龙果外观物理性状(单果重、果实纵径、果实横径)的效果最佳,TiO2稀释1 000倍和1 500倍处理对改善果实品质性状(维生素C含量、可溶性糖含量、固酸比、可溶性固形物含量)的效果较好。总体而言,TiO2对改善火龙果的品质有显著影响,其中稀释1 500倍处理效果最好。本研究将为浙江地区火龙果种植提供理论和实践借鉴。

Abstract:

In recent years, facility cultivation of pitaya has developed rapidly in Zhejiang Province. However, protected cultivation in the winter and spring seasons in Zhejiang Province is still affected by unfavorable factors such as low temperature and weak light, which often leads to low photosynthetic rate and seriously affects the commercialization of pitaya and the economic benefits of farmers. In this study, the pitaya cultivar Hongshuijing was used as the research material, and three different concentration treatments of a novel photosynthesis promoter (TiO2) were set up along with a control group. When the fruits ripened, the external physical properties and quality properties of pitaya were determined. The results showed that dilution of 1 500 times treatment exhibited the best effect in improving the appearance and physical properties (single fruit weight, fruit longitudinal diameter, and fruit transverse diameter) of pitaya. Both the dilution of 1 500 times and 1 000 times treatments had good effects on improving the quality properties (vitamin C content, soluble sugar content, soluble solid-acid ratio, soluble solid content) of pitaya fruits. In general, TiO2 had significant effects on the quality of pitaya, among which the dilution of 1 500 times treatment showed the best effect. The results of this study will provide new theoretical and practical references for pitaya cultivation in Zhejiang Province.
