| 摘 要：A 7-year microplot experiment was conducted to evaluate Cd-resistance of several main cultivated plants in south China. It revealed that cereals such as Oryza sativa and Zea mays had a strong resistance to Cd toxicity physiologically. Whereas, their products (grains) were easy to be polluted and hence lose their edible value. So they belonged to Cd-sensitive crops, and it was improper to be planted in the polluted soils. Other plants such as Brassica napus, Arachis hypogaea and Saccharum officinarum also had a strong resistance to Cd pollution physiologically. Meanwhile, Cd stocks in their products (oil or sugar) were very little and had few effects on their eatable quality. So these crops could be cultivated in some slightly Cd polluted farmlands. But the straw and dregs of oil crops, and sugarcane bagasse should be properly treated as pollutants, and they were not suitable to be used as manure or stock food. Fibre crops, such as Gossypium hirsutum, Hibiscus cannabinus, Boehmeria nivea and Morus alba were resistant to soil Cd pollution to some different degrees. There were basically no unfavorable effects of soil Cd pollution on the products of fibre crops. Moreover, there was hardly any Cd coming into the food chain through these crops. We should, therefore, take up these fiber crops to replace those sensitive crops in the polluted region previously. |
