猕猴桃套袋技术的生态效应

提出了猕猴桃套袋技术，并在田间系统研究了套袋对猕猴桃生长发育、温湿度效应及对病虫的控制效果，室内测定分析了套袋猕猴桃的营养物含量及农药残留量。结果表明，袋型不同，其生态效应差异明显，套膜袋能显著改变温湿度条件，袋内温度升高0．7～0．9℃，相对湿度增大10．8％～11．8％．果重增加25．7％～37．7％，商品果率提高20．4％～30．1％，病虫危害率降低87．5％～90．2％，贮藏性能好，化学农药使用量减少72．2％，果实中农药残留量仅为0．31mg·kg^-1，降低90．5％，减轻了化学农药对生态环境及猕猴桃果实的污染，为绿色果品的生产开辟了新途径，具有广阔的推广应用前景，套纸袋负效应明显，果色发黄，品质差，不宜推广应用。

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.
