Abstract

The rhizosphere environment of tea (Camelllia sinensis Kuntze) intercropped with persimmon (Diospyros kaki) differs from monocultures of tea. A trial was conducted to determine the effects of intercropping with persimmon on root exudates and soil nutrient condition of tea. Amino acid exuded in intercropping was three times higher than that in monoculture. Phenol, phenol/amino acid ration, dissolved sugar, and total organic acid were also lower in intercropping. The value of pH in soil was higher, and soil nutrient condition of rhizosphere, especially available nutrient, was not as well in intercropping as that in tea grown alone. While soil nutrient of non-rhizosphere was better than that in monoculture, tea quality and soil nutrient condition were better in intercropping ecosystem.
