以“斗南”苹果为试材,研究比较了疏花蔬果时保留中心花和保留边花对其所结果实霉心病发病率、单果重及果形指数的影响。结果表明:2011年和2012年中心花所结果实霉心病发病率分别为8%和36%,边花所结果实霉心病的发病率分别为4%和17%;边花所结果实与中心花所结果实的单果重、果形指数无显著差异。可见,疏花时选留边花坐果可以降低“斗南”苹果霉心病的发病率。
Taking “Dounan” apple as test material, this paper studied the effects of preserving central flowers and preserving border flowers on the incidence of moldy fruits, single fruit weight and fruit shape index when compared with the control. The results showed that the incidence of mold-borne disease was 8% and 36% respectively in 2011 and 2012, and the incidence of mold-borne disease was 4% and 17% respectively. Flowers fruited fruit weight, fruit shape index no significant difference. Visible, thinning flowers when the election to stay edge flowers can reduce the “Dounan ” the incidence of mildew in apple.
