摘要： The acidification of farmland soil in the red soil region of South China has led to the decrease of agricultural products, quality and soil degradation, which is in urgent need of improvement. In this paper, a field trial was implemented to study the effect of applying different amount of Tebeigai soil conditioner (namely 750, 1125, 1500, 1875 and 2250 kg/ha) on eggplant's yield, heavy metal content and basic physical and chemical properties of soil in red soil area. The results showed that: compared with the control treatment, the application of different doses of Tebeigai soil conditioner could increase eggplant yield by 15.5%similar to 55.8%; reduce As content of eggplant fruit by 12.8%similar to 51.8%, Cr content by 33.7%similar to 57.1%, Pb content by 1.9%similar to 19.2%, Cd content by 14.3%similar to 30.4%; at the same time, the soil pH increased by 5.8%similar to 18.6%, exchangeable acid (potential acid) decreased by 37.6%similar to 82.3%; and the contents of available Pb, Cd and Cr were decreased by 7.0% similar to 21.6%, 15.1% similar to 29.6% and 1.0% similar to 21.4%, respectively.
