[Objective]To explore a planting model that can improve soil physical and chemical properties,increase soil nutrients,and create a good growth environment for red pomelo.[Method]The effects of intercropping red pomelo with Vicia villosa and Galium odoratum on forage yield and soil properties were studied.[Result]The underground roots of Vicia villosa and Galium odoratum were mainly distributed in the 1-20 cm cultivation layer,and didn't overlap with the root growth of red pomelo trees in space.The height of both types of grass was about 30 cm,and they would not compete with fruit trees for nutrients and light,nor would they cause canopy closure and lack of ventilation in the orchard.The orchard temperature decreased by 0.7℃and 0.6℃,respectively.[Conclusion]After intercropping with grass,the orchard temperature was effectively reduced,soil moisture evaporation was reduced,soil fertility was improved,and the content of alkaline hydrolyzed nitrogen,available phosphorus,and available potassium were all increased,with Vicia villosa having the most significant effect.
