摘　　要：以6年生枳砧温州蜜柑为材料,研究在果实细胞分裂期、细胞膨大期以及成熟前期等3个时期进行地表覆膜对温州蜜柑果实品质和外观的影响。结果表明:在果实细胞分裂期和成熟前期进行覆膜,果实总糖、还原糖、VC的含量均高于对照,果实可滴定酸的含量以及果实纵横径、果皮重、单果重均低于对照,果实细胞分裂期覆膜使果实可食率高于对照,果形指数与对照无差异,果实成熟前期覆膜使果实可食率与对照无差异,果形指数低于对照;果实细胞膨大期覆膜,果实总糖、还原糖、可滴定酸的含量以及果实可食率低于对照,果实VC的含量比对照稍高,果实纵横径、果皮重、单果重以及果形指数均低于对照。果实成熟前期覆膜,可有效提高果实总糖、还原糖、VC的含量,降低果实可滴定酸的含量,从而提高果实品质,但对果实外观有一定的负面影响。In the orchard of six-year-old satsuma orange （Citrus unshiu） trees, the bare land was covered with plastic film at 3 growth stages, and the effects of the mulching on the fruit quality and appearance of satsuma orange were studied. The results showed that： in comparison with the control, the mulching at fruit cell division stage or at earlier fruit mature stage increased the contents of total sugar, reducing sugar, and Vc in fruits, and reduced the fruit titratable acid content, fruit size, pericarp weight and single-fruit weight. The mulching at fruit cell division stage could enhance the edible rate of fruits, but had no influence on fruit- shape index. The mulching at earlier fruit mature stage could decrease the fruit-shape index, but had no influence on the edible rate of fruits. The mulching at fruit cell expansion stage decreased the contents of total sugar, reducing sugar, and titratable acid in fruits, the edible rate of fruits, as well as the fruit size, pericarp weight, single-fruit weight and fruit-shape index. Therefore, the mulching at earlier fruit mature stage could improve the quality of fruits, but it had a certain negative influence on the appearance of fruits.
