不同材质果袋对哈密瓜果实微域环境及品质的影响

【目的】研究不同材质果袋对哈密瓜果实微域环境及品质的影响,为哈密瓜田间生产提供指导。【方法】以“黄皮9818”甜瓜品种为材料,采用白纸袋、硫酸纸袋、塑料膜袋、淋膜纸袋4种不同材质的果袋,不套袋(CK)为对照,进行哈密瓜果实套袋试验,并测定不同材质果袋中微域环境,及对哈密瓜外观和营养品质的影响。【结果】哈密瓜套袋后,微域环境的温度、光照均低于对照(CK),除塑料膜袋外,其它材质果袋均能有效防止果面灼伤;而各套袋处理哈密瓜营养品质中总酸、蛋白、水解还原糖、VC含量无明显差异。【结论】在哈密瓜露地栽培条件下,淋膜纸袋为较理想果袋,果实平均单果重(1.52kg)、商品率(82.80%)最高,且果面鲜亮干净,网纹细密,水浸斑较少。

Effects of Different Fruit Bags with Different Materials on Hami Melon Microenvironment and Quality

【Objective】 The objective of the study is to investigate the effect of different fruit bags with different materials on the microenvironment and fruit quality of Hami melon in the hope of providing guidance for field production.【Method】The fruit bagging experiment of Hami melon was carried out by using "Huangpi 9818" melon variety under the field drip irrigation mode as control and using four kinds of fruit bags with different materials, such as white paper bag, sulphuric acid paper bag, plastic film bag and coated paper bag. The microenvironment in different fruit bags and their effects on the appearance and nutritional quality of Hami melon were also determined.【Result】The results showed that the microenvironment temperature and light of Hami melon were lower than those of CK after bagging. Except plastic film bag, all other fruit bags could effectively prevent the fruit sunburn. However, there was no significant difference in the contents of total acid, protein, hydrolytic reducing sugar and vitamin C in the nutritional quality of Hami melon treated by bagging.【Conclusion】Under the condition of open field cultivation of Hami melon, film paper bag was the ideal fruit bag, the average fruit weight per fruit was 1.52 kg, the commodity rate was 82.80%, the fruit surface was bright and clean, and the net grain was fine. Besides, there are fewer water spots in the fruit.
