自制生物保护膜对瑞雪苹果果实品质的影响OA

To develop a biological protective film suitable for bag-free cultivation of'Ruixue'apples,8-year-old'Ruixue'apple fruits were used as test materials,and two self-made biological protective films were sprayed.Spraying Kangluwei organic film protective agent and bagging with special fruit bags were set as controls to systematically evaluate the effects of the two self-made biological protective films on fruit quality.The results showed that,compared with bagging with special fruit bags,spraying self-made biological protective films could significantly increase the single fruit weight,fruit longitudinal diameter and the red-green chromaticity of fruit surface,and the fruit surface smoothness was close to that of the bagging treatment;compared with the treatment of spraying Kangluwei organic film protective agent,spraying self-made biological protective films could increase the soluble solid content,solid-acid ratio,total phenol content,total flavonoid content and total flavonoid content of fruits.Spraying either of the two self-made biological protective films can improve fruit quality.Among them,the treatment of spraying self-made biological protective film 2 performs best in both fruit appearance and internal quality,and can be used for bag-free cultivation of'Ruixue'apples.
