研究了地面覆盖反光膜对早熟温州蜜柑果实着色及品质的影响。结果表明,覆膜后,柑桔果皮色泽指数呈正值,果皮亮度值(L)达到70以上,其着色状况明显优于对照(空白),极大地改善了柑桔外观着色。试验还表明,早熟温州蜜柑秋季地面覆盖反光膜的最佳时期在完熟采收(11月上旬)前30～40天,若此期覆膜,龟井、兴津和宫川等3个温州蜜柑品种的果实外观着色明显优于对照,果实内在品质有较大幅度地提高,糖度比对照提高0.7个百分点以上。
The effect of ground-covered reflective film on the coloring and quality of early-matured Wenzhou mandarin orange fruit was studied. The results showed that the color index of citrus peel was positive after coating, the peel brightness value (L) was above 70, and its coloring status was significantly better than the control (blank), which greatly improved the appearance of citrus. The experiment also showed that the best time for early autumn Satsuma osmanthus reflective coating on the ground in the mature harvest (early November) 30 to 40 days, if the coating, Kamei, Xingjin and Miyagawa three Satsuma The appearance of the fruits of the varieties of coloration was significantly better than the control, the intrinsic quality of the fruits have a more substantial increase in sugar content than the control increased by 0.7 percentage points or more.
