[Ecological effects of bagging on actinidia fruits]

Studies on the ecological effects of bagging on actinidia fruits showed that under different types of bagging, the ecological effects on actinidia fruits were different. Bagging with membrane changed the conditions of temperature and humidity. The inside temperature raised by 0.7-0.9 degree C, humidity increased by 10.8%-11.8%, single fruit weight increased by 25.7%-37.7%, commercial fruit rate raised by 20.4%-30.1%, percentage of diseases and pests decreased by 85.7%-90.2%, and storage property was good. Additionally, the application rate of chemical pesticide was reduce by 72.2%, and the concentration of remnant pesticide inside fruits was only 0.31% mg.kg-1, which was decreased by 90.0%. The chemical pesticide pollution in ecological circumstance and actinidia fruits both reduced. It would be a new way for the rgeen fruits production in the future. Bagging with paper has obvious negative effects.
