摘　　要： 为探讨叶幕微气候对板栗果实品质的影响,在燕山板栗产区,选取生长健壮,无病虫害的10a生遵达栗3株,测量树冠内不同区域环境因子和果实品质分布,并进行相关分析。结果表明,树冠内不同区域的光照、温度、湿度存在差异并且有一定的分布规律,差异最大值分别为光照6.5×104lx、温度3℃、湿度45%。树冠内不同区域板栗养分含量存在差异并且与环境因子相关,与光照、温度呈正相关,相关系数分别达到0.82和0.83,与湿度呈负相关,相关系数达到-0.71。 To explore the influence of canopy microclimate on the quality of chestnut, three 10-years-old chestnut trees which were healthy and had no pests were selected for experiment in the Yanshan chestnut production area. The environmental factors and the quality of fruits in different regions in the canopy were measured, and correlation analysis was done as well.. The results showed that light intensity, temperature, humidity and other environmental factors varied considerably in different regions in the canopy and there were regularities of distribution. The maximum differences of light intensity, temperature, humidity reached 6.5×104 lx, 3 ℃ and 45%,respectively. Contents of nutrition of the fruits varied considerably in different regions in the tree canopy and was related to environmental factors. The fruit quality was positively related to light intensity and temperature, and the correlation coefficients were 0.82 and 0.83, respectively. But it was negatively related to humidity, and the correlation coefficient was -0.71.
