研究了苹果生长季节腐烂病发生规律。结果表明,苹果腐烂病菌越冬存活率为64.0%。在苹果生长季节内病疤面积扩展有两个高峰,在第一高峰期病斑扩展较为迅速,第二高峰期相对较慢(分别为6月和9月)。不同季节腐烂病的发病率,以春季接种发病率最高达88.83%,其次为夏季和秋季,冬季最低,为2.75%。
The law of apple rot disease was studied. The results showed that the survival rate of apple rot pathogen overwintering was 64.0%. Within the growing season of apple, there are two peaks in scar area expansion, the lesion spread more rapidly in the first peak, and the second peak is relatively slow (June and September respectively). The incidence of rot disease in different seasons, the incidence of spring vaccination up to 88.83%, followed by the summer and autumn, the lowest winter, 2.75%.
