反射膜在芒果运输中的温度调节作用

Temperature Regulation of the Reflex Film in Mango Transportation

芒果运输中的环境温度对果实的呼吸代谢、蒸腾作用、酶活性、乙烯产生等生理生化过程起着主导作用，温度升高芒果成熟加快，易造成腐烂变质。为了改变运输过程中太阳辐射热造成的小环境增温，使用在塑料编织布上涂反射膜的方法，降低太阳辐射增温。经实测，反射膜能把８５％的太阳辐射反射或散射掉，透过率低于１０％，从而阻止了太阳辐射对车内的增温效应，避免了由于车内温度剧变对果实的伤害作用。为长途运输的降温提供了实用、简便的方法。

During the dynamic transportation of the fruit named Mango,the temperature plays a main role for the fruit breathe,transpiration,enzyme living and ethylene produce.The Mango is ripen faster as the temperature increasing,therefore this is disadvantageous for the fruit transportation.For reducing the increasing temperature effect of the solar radiation on Mango transportation,the new method that the reflex film was spreaded on the plastic weave cloth was suggested.Thus,85% solar radiation was reflected and scattered by the reflex film ,and its transmissivity was less than 10%.The reflex film protects the transportation from the increasing temperature effect of the solar radiation and the fruit harming caused temperature severe change within the vehicle was avoided.
