Environmental model of meteorological risk of strawberry powdery mildew in solar greenhouse

Early warning for greenhouse crop disease is an essential way for protecting eco-environment and crop quality safety. Solar greenhouse provides suitable growth environment for crops, but also provides favourable conditions for disease occurrence. With the increase of strawberry area in Hebei Province, powdery mildew has become one of the main diseases of greenhouse strawberry. In order to better predict the risk degree of strawberry powdery mildew occurrence during its latent period from the meteorological perspective, temperature, humidity, and time were selected as model building factors in this study to build a cubic environmental prediction model of meteorological risk degree of strawberry powdery mildew. Meteorological data and powdery mildew data of strawberry shed in Panchang test base in Langfang city in 2021 were used to verify the model. The results showed, the cubic meteorological risk environmental model can better predict the risk of strawberry powdery mildew occurrence in the latent period. By changing greenhouse environmental factors, farmers can avoid the occurrence of strawberry powdery mildew in a large area, and green production of strawberry can improve its economic benefits and help rural revitalization.
