水果套袋可以为果实发育创造相对封闭而又透气的微环境,能显著提高果品外观质量和减少农药残留污染,是生产无公害水果、增强果品国际竞争力的一项关键技术。我国90年代开始推广该项技术。2000年全国使用果袋200亿只。 水果套袋的实质是使果实与外界隔离,有效地改变果际微环境,包括光照、温度、湿度等。套袋可以显著地改善水果的外观品质,使果面光洁美观,着色均匀,防止裂果。水果套袋后,农药、细菌、真菌和烟尘不易 Fruit bagging can create a relatively closed and breathable microenvironment for fruit development, which can significantly improve the quality of fruit appearance and reduce pesticide residue pollution. It is a key technology for producing pollution-free fruits and enhancing the international competitiveness of fruits. China started to promote the technology in the 90s. In 2000, 20 billion fruit bags were used nationwide. The essence of fruit bagging is to isolate the fruit from the outside world, effectively changing the fruit micro-environment, including light, temperature and humidity. Bagging can significantly improve the appearance of fruit quality, smooth and beautiful fruit surface, uniform coloring, to prevent cracking fruit. After fruit bagging, pesticides, bacteria, fungi and smoke are not easy
