Abstract: The changes of air temperature, relative humidity, light intensity and dew point of meteorological factor on Solanum tuberdsm and Allium Chinese interplanting were observated in October. The effects of autumn intercropping of Camellia oleifera on microclimate was studied. The results showed that crops with the ability to regulate the air temperature in the forest were ranked as Allium Chinese > Solanum tuberdsm > tillage (control). Crops with the ability to regulate the air humidity in the forest were ranked as Allium Chinese > Solanum tuberdsm > tillage (control). Crops with the ability of adjusting light intensity in the forest were ranked as Solanum tuberdsm > Allium Chinese > tillage (control). Crops with the ability to regulate dew point in the forest were ranked as Allium Chinese > Solanum tuberdsm > tillage (control). Therefore, Solanum tuberdsm and Allium Chinese can significantly improve autumn microclimate of Camellia oleifera young plantation. The results can provide a reference for the improvement of autumn microclimate of Camellia oleifera intercropping.
