摘　　要：2010年7月中旬在望都县万亩苹果基地抽查3个套袋苹果品种,调查果实日灼率发生情况。结果表明:套纸袋的"富士"和"斗南"日灼率为11%和14%,套塑料膜袋的"王林"日灼率为26%。对气象资料分析发现,7月5日和6日的高温、强日照天气可能是导致此次苹果日灼病发生的主要原因,并据此提出了预防苹果日灼病的相关对策。In order to know about the sunburn rate of the apple fruit,we investigated three varieties of bagging apples in the middle of July 2010 in Wangdu county.The result showed that the fruit sunburn rates of＂Fushi＂and＂Dounan＂bagged with papers were 11%and 14%respectively,and that of＂Wanglin＂bagged with plastic membrane was 26%.Analysis of the meteorological data showed that high temperature and strong sunlight on the 5th and the 6th of July should be the main reasons causing the sunburn disease.Some methods to prevent the sunburn disease of apples were also discussed in the paper.
