| Abstract: | Environmental reconstruction, decontamination and resuming the soil quality are the traditional strategy to renovate the cropland polluted by Cd. This article puts forward an agricultural ecological renovation strategy for using polluted cropland in high efficiency. We take polluted cropland as a kind of special resource. Through the choice of Cd resistant lawngrasses, the polluted cropland could be used in safe and high efficiency way. Instead of food production mode, the lawngrass production mode could stop the pollution, eliminate the harmness of Cd in the food chain and resume the soil productivity. |
