摘　　要：[目的]了解不同栽植密度杏园的温湿度变化规律,为选择合理建园密度及整形修剪奠定基础.[方法]用EI-USB-2型温湿度记录仪,对不同栽植密度杏园不同部位的温湿度变化进行测定,分析其温湿度差异.[结果]杏园内部温度比外部（对照）温度低,而湿度高于外部（对照）,一天中温度的变化都呈现出“低-高-低”的规律,而相对湿度的变化则反相关.杏园的株间、行间和树冠中心的温度从大到小依次为：行间＞株间＞树冠中心,相对湿度变化则相反.不同密度的杏园在15：00 ～ 16：00温度差异较大,温度变化从大到小依次为：8 m×8 m＞4 m×8 m＞4 m×6 m＞4 m×4 m＞2 m×4 m,湿度变化相反.[结论]不同栽植密度杏园内温湿度差异显著,栽植密度小的杏园温度小湿度大,栽植密度大的杏园温度大湿度小,4 m×6 m、4 m×8 m为较适中的栽植密度.[Objective] To master the variation of temperature and humidity of apricot orchards with different planting densities,and to lay a foundation of choosing the reasonable density for orchard construction and training and pruning.[Method]The temperature and humidity recorder,EI-USB-2 was used to to measure the temperature and humidity changes of different parts in apricot orchards with different planting densities,and the difference of temperature and humidity among them were analyzed.[Result] The internal temperature of the apricot orchard was lower than the outer （control） temperature,and the humidity was intenser than the external （control）,the change of temperature in a day showed a ＂ low-high-low＂ rule,and the change of the relative humidity was the inversely correlated.The temperature of inter-plant,inter-row and canopy center in the apricot orchards from big to small in turn was：inter-row ＞ inter-plant ＞ canopy center,while the change of relative humidity was just the opposite.From 3 o＇clock to 4 o＇clock in the afternoon,there was great difference in temperature among apricot orchards with the different densities.Temperature changes from big to small in turn was：8 m×8 m＞4 m×8 m＞4 m×6 m＞4 m×4 m＞2 m×4 m,and variations of humidity were just contrary to the change of temperature.[Conclusion] The significant difference of temperature and humidity were decided by the planting density in the apricot,and the planting density had a great influence on the temperature and humidity of apricot; In the low density of apricot orchard,the temperature was low and humidity was high,and it was found that the temperature was high and the humidity was low in the high density apricot orchard,i.e.the temperature and humidity in the high and low density of apricot orchard were the opposite,and we felt that the proper densities were 4 m × 6 m and 4 m × 8 m.
