摘要
2006～2007年对温岭市梨大棚内外温、湿度的变化规律进行观测与比较。结果表明:大棚内外的温、湿度变化都具有良好的同步性,气温和地温均呈逐渐上升趋势。促成栽培期大棚内的温、湿度均明显高于露地,温度的提高是梨大棚栽培提早成熟的重要因素。不同天气类型气温的高峰值均出现在中午时段,最高温度与最低温度的差异幅度晴天>阴天>雨天。晴天12:00～14:00空气相对湿度最小,22:00～24:00空气相对湿度最大,相同时间段相对湿度雨天>阴天>晴天。
The change low of temperature and humidity had been surveyed and compared in plastic house and open ground for pear of wenling city duing 2006 - 2007. The results indicated that changes of temperature and humidity all had a good synchrany to the plastic house and open ground, and air temperature and oil temperature were gradually on the rise. The temperature and humidity in the plastic house were significantly higher than those in the open ground duing the cultivated period , so increasing the temperature was an important factor to make the pear＇s maturity earlier in plastic house. The peak of temperature with different types of weather appeared at the noon, the difference ranges with sunny between the maximum temperature in clear day and minimum temperature were the highest, followed by the cloudy day and rainy day. Relative air humidities of clear day were the least duing 12：00 - 14：00, and were the most duing 22：00 -24：00 the relative humidity of rainy day was the highest,cloudy day was higher than cleary day at the same phase.
