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.
