南方典型區(qū)域水稻鎘富集系數(shù)差異影響因素探析
[Abstract]:The difference of cadmium uptake in rice from typical rice producing areas in southern China was analyzed by means of self-sampling analysis and other research results. The results of ANOVA showed that the CD enrichment coefficient of rice in southern China was significantly different and could be divided into high uptake (average enrichment coefficient and standard deviation was (0.96 鹵0.73), middle and high uptake (0.64 鹵0.59). There are four types of low absorption (0.29 鹵0.22) and low absorption (0.26 鹵0.30). In 19 study areas, the middle and low absorption types (enrichment coefficient between 0.2 and 0.3) are the most common among the four types. The effects of pH, organic matter content, texture, soil type, soil cadmium content and soil Zn/Cd on CD concentration coefficient of rice were discussed. The effect of soil pH on CD enrichment coefficient of rice was the greatest and it was in accordance with Weibull nonlinear equation model. The effect of soil organic matter was significantly lower than pH, and the effect of soil texture on CD enrichment coefficient of rice was greater than that of alkaline condition under acidic condition, and the effect of soil Zn/Cd ratio on CD enrichment coefficient of rice was also more prominent. In the soil with high Zn/Cd ratio, the CD concentration coefficient of rice is generally lower, but the effect of soil type and soil CD content on the CD enrichment coefficient of rice has great regional difference.
