%X Zhangshi Irrigation Area is notorious for its cadmium pollution in this country, which has bad effects in human health through food chain. So it is very imperative to adopt a comprehensive way of prevention and improvement. In this report, various methods have been summed up to decrease Cd uptake by rice plant during 1980-1983. They are by:1. Reducing Cd concentration and increasing pH value in irrigation water,2. Applying soil supplement materials: lime, Ca-Mg-P fertilizer, etc.,3. Taking off polluted surface soil at different depth or covering the polluted top soil with unpolluted one,4. Biological methods: in addition to rice, other kinds of crops are planted, such as soybean, corn, sunflower, etc. and using Cd-polluted rice as breed good strains.These experiments have been carried out in polluted fields. And, conclusions are, of course, suitable for this particular area.
