遮阴及地膜覆盖对黄皮果实表面温湿度变化及果实品质的影响

以金鸡心黄皮为试材，研究了遮阴及地膜覆盖处理对黄皮果实品质与果实表面温湿度变化的影响。结果表明：阴雨天气下，遮阴及遮阴＋地膜覆盖处理的果实表面日平均湿度低；晴天天气下，地膜覆盖处理及对照果实表面的日平均温度高，昼夜温差大，阴雨及晴天天气下温度变化、湿度变化趋势基本一致；地膜覆盖提高了果实品质，遮阴及遮阴＋地膜覆盖降低了果实好果率。

Effects of shading and plastic film mulching on changing of temperature and humidity and quality of wampee fruit

The wampee Clausena lansium （ Lout. ） Skeels ] cultivar ＇ Jinjixin＇ was used to study the effects of fruit quality and changing of temperature and humidity under shading and plastic film mulching. The results indicated that daily mean relative humidity under shading and shading ＋ plastic film mulching treatments was lower than the left treatments in rainy weather condition. Whereas, in sunny weather condition, daily mean temperature and temperature difference of day and night were higher under plastic film mulching and control. And similar changing trends were kept in temperature and relative humidity no matter rainy and sunny weather condition. Plastic film mulching increased fruit quality and shading and shading ＋ plastic film mulching decreased the percentage of the healthy fruit.
