连续7年在苹果生长季内每隔2周加钙盐或不加钙盐对果实进行喷雾处理,并在果实采收贮藏6周后,确定“桔苹”果实外部和内部的苦痘病的发生率。此外,在采果后,用氯化钙进行真空渗透处理。结果表明,喷钙后并经钙渗透处理的果实的苦痘病得到了最大程度的控制,但不显著。只进行渗透处理比之喷钙更能降低罹病程度,而且在降低外部苦痘病更有效。结果显示。为预防苦痘病,在生长季内喷钙优于采后用钙进行真空渗透处理。
For seven consecutive years in the apple growing season every two weeks with calcium salt or no calcium salt on the fruit spray treatment, and in the fruit harvest storage for 6 weeks, to determine the “orange apple ” fruit outside and inside the bitter pox The incidence of disease. In addition, vacuum-infiltration treatment is carried out with calcium chloride after picking the fruit. The results showed that bitter pox disease was most controlled, but not significant, after spraying calcium and infiltrated with calcium. Permeation alone is more effective at reducing disease severity than calcium spray and is more effective in reducing external bitter pox disease. The results show. In order to prevent bitter pox disease, spraying calcium in the growing season is better than using calcium for vacuum infiltration after harvesting.
