摘要
为了探究文冠果树冠内不同方向和区域中微气候的变化情况和对结果的影响,在内蒙古阿鲁科尔沁旗文冠果园内选取4株长势一致的4年生文冠果树开展研究。结果表明:树冠内不同区域的温湿度差异不显著,光照是影响树冠内微气候变化的主要影响因素;除日间温差外,不同方向对环境因子的再分配影响微弱;不同区域间可孕花数量、果实产量和单果重差异显著,且与光照呈显著正相关关系,相关系数分别为0.66、0.85和0.75;果实含油率与光照的关系主要体现在光照低于4 000 lx的区域没有果实产出,剔除无果实区域后发现对于已有果实的含油率与光照无显著相关关系。
To explore the micro-climate in the tree canopy ofXanthoceras sorbifolia, four 4-year-old trees were selected for the research in a orchard in Inner Mongolia. The crow were divided in 32 areas and light intensity, temperature, humidity and the fruit yield were recorded in each area. The result shows that temperature and humidity were not significantly different amount these areas, while the light intensity was an significant factor. Primary, these differences come from the locations of the area while direction was not an significant factor. Fertile flower, production and the weight of single fruit from different areas are significant different and positive correlated with light intensity and, the correlation coefficients were 0.66, 0.85 and 0.75.Seed oil content is also correlated with light intensity, but if none fruit areas （light intensity lower than 4 000 Lx） were eliminated, the oil content was not significant related with light intensity.
