[Effect of bagging on greenhouse cucumber].
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 0.760 mg x kg(-1) and 1.2208 mg x kg(-1), reduced by 83.3% and 73.2%, respectively, compared to non-bagging.
