Abstract: The study showed that culturing cucumber with film bag increased cucumber yield by 12.3%～15.1%,reduced abnormal cucumber by 65.3%～72.8%,and the shape of cucumber was straight and smooth.The keeping-fresh period of the cucumber prolonged to 20～25 days,its vitamin C increased 21.9%,and total sugar increased to 5.1%.Paper bagging increased cucumber yield by 7.2%～10.1%,and reduced abnormal cucumber by 52.2%～57.7%.Bag body could efficiently prevent the cucumber from the direct pollution of chemicals spray.The survival pesticides in film and paper bags was 0.760mg·kg^-1 and 1.2208 mg·kg^-1,reduced by 83 3% and 73.2%,respectively,compared to non-bagging.
