Abstract: The paper aims to study the effect of meteorological condition in different growth stages of blueberry on the quality formation, and provide reference for improving scientific introduction and planting management. With the blueberry quality data from 14 planting sites of different altitudes and different slopes in 2012 and 2013, the effects of meteorological elements on blueberry quality were analyzed by using correlation analysis method. The results showed that: heat condition was the most important factor of blueberry quality. The heat condition from budding to full productive stage directly affected the accumulation of fruit sugar and had large effect on blueberry taste. Temperature, precipitation and sunshine hours had relatively great influence on blueberry fruit quality from early fruiting to full productive stage. Low temperature in the flowering stage and too much rain in the maturity stage were main unfavorable meteorological factors that affected the quality of blueberry planting in Guizhou.
