With the peach fruits of ‘Hujingmilu’,‘Jinxiuhuangtao’ and ‘Zaolupantao’ as material,the effects of the reflecting film application on soluble solids content,mean fruit weight and fruit colouring of the mid lower portion were studied.The results showed that the fruit colouring degree of the fruits(Treat) was significantly higher than that of the fruits(CK) in the fruits of three peach cultivars(P<0.01);soluble solids content of the fruits(Treat) was significantly higher than that of the fruits(CK) in ‘Zaolupantao’(P<0.01),and soluble solids content of the fruits(Treat) was higher than that of the fruits(CK) in other peach cultivars(P<0.05);mean fruit weight of the fruits(Treat) was significantly higher than that of the fruits(CK) in ‘Zaolupantao’(P<0.01),but there were no significant differences in mean fruit weight between CK and Treat in other peach cultivars(P>0.05).
