[0002] Blueberry is an emerging berry economic tree species in recent years. With economic development and the improvement of people's living standards, consumers' demand for high-quality blueberry fruits has increased year by year. In recent years, the area of ​​blueberry in China has expanded rapidly. As of now, the blueberry planting area in my country is about 77,000 hectares, mainly adopting the facility substrate cultivation mode. However, the facility cultivation condition is a semi-closed environment, and often there are problems such as high humidity in the greenhouse. High humidity can easily lead to the outbreak of gray mold during flowering and low fruit set rate, which seriously affects the yield and even the total yield in some years, resulting in poor economic benefits of some specific varieties. To improve the economic benefits of facility blueberry substrate cultivation, increase the fruit set rate, and reduce the occurrence of gray mold, it is urgent to reduce the humidity in the facility greenhouse and accelerate air circulation.
