摘 要:以4年生枳壳砧晚棱脐橙树为试验材料,采用简易塑料大棚设施栽培模式,研究了设施条件下树冠内环境因子的变化特征,结果表明:简易塑料大棚树冠内温湿度与外界大气环境温湿度密切相关(相关系数R2分别为0.7359和0.7489),大棚内平均温度提高约1.6℃,湿度略有下降。对白天和夜晚设施内外温度差的分析表明,白天设施内平均增温4.8℃,晚上则恰好相反,内外温差为-1.2℃;设施内白天升温和夜间"逆温"现象并存,且不受天气类型的影响。Taking 4-year-old lane late navel orange as research material, the author used a simple plastic-film greenhouse to study the change characteristics of temperature and humidity in the crown of tree. The results showed that the temperature and hu- midity in the tree crown in the simple plastic greenhouse were closely relevant to those in the open air (the correlation coefficient R2 was 0.7359 and 0.7489, respectively), the average temperature in greenhouse was 1.6 ℃ higher, and the humidity was slightly low- er than those in the open air. The temperature gap between inside and outside of greenhouse was averagely 4.8 ℃ ( high inside and low outside) in daytime, and -1.2 ℃ in night. Both the temperature rising in daytime and the temperature inversion in night hap- pened in the greenhouse, which were not affected by the types of weather.
