采用植物体内温度监测系统,监测了库尔勒香梨树干形成层的温度和主要气象因子,分析了树干阳阴面形成层温度变化特性并探讨了融冻和日灼发生的可能性。结果表明:树干阳阴面形成层温度变化有季节特性,阳面温度变化比阴面强烈,尤其是冬季更加明显;夏季阳阴面温度差异较小;白天树干阳面形成层温度高于阴面,夜间阴面温度略高于阳面;阳面日较差最高值出现在冬季,达33.14℃,比阴面日较差高17.14℃;越冬期间树干阳面日最低温度低于阴面,最高温度高于阴面,说明树干阳面比阴面更容易受到低温冻害和日灼危害;夏季树干阳面形成层日最高温度高于阴面且大于40℃高温持续日数在20d以上,说明树干阳面形成层比阴面更容易受到日灼的危害。
The plant temperature monitoring system was used to monitor the temperature and the main meteorological factors of the formation layer of Korla fragrant pear trunk. The temperature variation characteristics of the formation layer of the tree trunk positive and negative was analyzed and the possibility of thawing and sunburn occurred was discussed. The results showed that the temperature of the formation layer of the sun and the shades of the trunk had the seasonal characteristics, the change of the temperature of the sun surface was stronger than that of the cloudy surface, especially in winter, and the temperature difference between the sun and the shades was small in summer. On the sunny side, the highest value of the sun on the sun appeared in winter, reaching 33.14 ℃, which was 17.14 ℃ higher than the negative on the sun. The lowest temperature of the sun on the sunrays was lower than that on the negative during the wintering period, indicating that the sunrays were easier than the sunrays The frost damage and the sunburn were harmed. The maximum daily temperature of formation layer on the sun trunk in summer was higher than that on the cloudy side and the duration of days longer than 40 ℃ was above 20 days, indicating that the sunburst formation layer of the trunk was more susceptible to the sunburn than the cloudy side.
