摘要： 冠层微气候的监测是精细农业的发展的必然要求。苹果树冠层温湿度是影响果树生长、决定苹果质量和产量的直接因素，冠层温湿度的监测方案及策略是由其分布特性决定的。为了研究冠层温湿度的时空分布特性，进行了实地试验持续地监测了苹果树冠层多个位置点的温湿度，在不同的冠层不同的日期进行了2次试验以相互验证。试验结果表明：时间上在太阳最为活跃的中午前后，空间上在果树冠层靠顶部和边缘的位置温度随时间的波动最大；冠层温度的极值点最多出现在沿着主干的直线方向上。【结论】由此,可得出结论:中午前后及冠层边缘处的监测频率应较大一些；提出了一种优先监测冠层中心沿着主干方向2~3个位置点，再监测冠层其他点的监测策略

Abstract: Canopy micro-climate monitoring is an inevitable demand of precision agricultural development. Temperatures in an apple tree canopy are key factors that impact the tree growth and fruit quality and quantity, and temperature monitoring strategy is determined by its distribution characteristics in the canopy. Field test was performed to monitor temperatures at a few positions in an apple tree canopy continuously, and the test was conducted repeatedly in a different canopy on a different date for verification. The results showed that around noon when the sun was the most active in time, and at the top and on the edge of a canopy in space the temperature changed the most with time; The temperature extreme values appeared the most in the line along the trunk. It could be concluded that the monitoring frequency around noon and at the top and on the edge of the canopy should be set higher than the other places, and that 2-3 positions in the line along the trunk should be monitored prior to the other positions.
