摘　　要：以晚熟柑橘塔罗科血橙为材料,在冬季(12月至次年2月)于塔罗科血橙园区内设置塑料大棚,以研究大棚内温度变化情况及对柑橘果实品质的影响。结果表明,大棚提高了棚内的日最低气温,增温幅度在0.2~3.6℃;大棚也明显提高了日最高气温,增温幅度在0.5~10.8℃,棚内的气温日较差较大棚外大,且寒潮天气和晴好天气温差更明显。大棚内塔罗科血橙着色效果较大棚外差,大棚有效提高了塔罗科血橙的可食率、出汁率、可溶性固形物含量和糖分含量,降低了总酸的含量,增加了固酸比。Using Tarocco blood oranges were used as materials,a plastic greenhouse was set up in Taroko Blood Orange Garden in win⁃ter(December-February of the following year)to study the temperature change and its effects on the quality of citrus fruits.The results showed that the daily minimum temperature in the greenhouse was increased by 0.2~3.6℃,and the daily maximum temperature in the greenhouse was also significantly increased by 0.5~10.8℃.The diurnal temperature difference in the greenhouse was larger than that outside,and the temperature differences during cold wave and fine weather were more obvious.The coloring effect of Taroko blood or⁃ange outside was better than that in greenhouse.The greenhouse effectively increased the edible rate,juice yield,soluble solids and sugar content of Taroko blood orange,decreased the total acid content and increased the solid-acid ratio.
